In Mexico, redberry disease in blackberry (Rubus sp.) was first observed in Tacambaro, Michoacan, in 2011, causing losses greater than 70%. In this study, the eriophyid mite species associated with buds and berries and its association with redberry disease were identified. Based on morphology, the specimens of mites collected from the buds and fruits were identified as Acalitus orthomera (Keifer in Bull Dept Agric State Calif XL(3):93–104, 1951) (Acari: Eriophyidae). The eriophyid mite densities in the buds of fruiting laterals were moderately to highly positively correlated (ρ = 0.6–0.95) with redberry disease incidence at harvest. In the second part of this study, the effects of different management strategies on the density of A. orthomera in fruiting lateral buds and redberry disease incidence were evaluated. Two IPM and organic experimental plots were established during the 2014 and 2016 seasons. Treatments were based on sequential or alternating applications of lime sulfur, plant extracts, soybean oil, the entomopathogenic fungus Hirsutella thompsonii, and acequinocyl, abamectin, and hexythiazox. Treatments were applied either from budbreak or the start of the blooming period. Management programs based on the application of lime sulfur alone or in blocks or alternating with acequinocyl, abamectin, or neem extracts were effective in reducing A. orthomera densities in buds and the incidence of redberry disease when applied either after budbreak or at the beginning of the blooming period; some of these treatment schemes are feasible for use in organic systems. These results will contribute to optimizing the management of redberry disease in blackberry in the context of integrated pest management.

Plants of the genus Nothofagus (Fagales, Nothofagaceae) has ancient South American-Australasian disjunctive distribution and represent a perspective model for biogeographical studies in Eriophyoidea. Among six currently known eriophyoid genera reported from Nothofagus (Acalitus, Aceria, Austracus, Cymoptus, Rectalox, and Nothacus) only genus Cymoptus was registered in western and eastern distribution areas of Nothofagus. In this paper we describe a new vagrant species, Solenocristus nothofagalis n. sp. (Phytoptidae, Sierraphytoptinae) collected from lower leaf surface of Nothofagus pumilio in Los Glaciares National Park (Patagonia, Argentina). Because all mite specimens in the sample were dead, amplification of three marker genes (COI, 18S, 28S) performed ten days after collecting data was unsuccessful. Morphological identification of the host plant was confirmed using PCR method and resulted in new sequences of 18S (MT164471) and ITS1‒5.8S‒ITS2 region (MT164174) of N. pumilio, deposited in GenBank.

Eriophyoid mites from plum trees (Prunus domestica L.) in Hamadan Province, northwestern Iran, were collected during a survey in 2018–2020. Altogether 12 species, belonging to eight genera and two families, are reported herein. Five species are new to science and five species are new records for Hamadan province of Iran. The collected mites according to their families, genera and species are as follows: family Diptilomiopidae: Quadracus reticulatus sp. nov., Rhinophytoptus nemalobos Lotfollahi & de Lillo, 2014, Diptacus hamedanicus Jafari & Khanjani, 2020, Diptacus gigantorhynchus (Nalepa, 1892); family Eriophyidae: Acalitus iranicus sp. nov. causes small irregular galls around of buds, Aculus flechtmanni sp. nov., Aculus fockeui (Nalepa & Trouessart, 1891), Eriophyes prunorum sp. nov. causes blisters on leaf surface, Eriophyes savagei Keifer, 1939 causes leaf nail galls, Phyllocoptes hamedi sp. nov., Phyllocoptes abaenus Keifer, 1940, and Tetra pruni Jafari, Khanjani & Ueckermann, 2020.

Apricot bud gall mite, Acalitus phloeocoptes (Nalepa), is a destructive arthropod pest that causes significant economic losses to apricot trees worldwide. Infested bud examination revealed that the starch granules in the bud axon were extended at the onset of the attack. During the later stages of the attack, the cytoplasm was distributed in apricot. The results also demonstrated that the accumulation of large amounts of cytokinin (zeatin, ZT) and auxin (indoleacetic acid, IAA) led to rapid bud proliferation during the rapid growth period. Abscisic acid (ABA) controls the development of gall buds and plays a vital role in gall bud maturity. The reduction of gibberellic acid (GA3) content led to rapid lignification at the later phase of bud development. Our results reveal the mechanism underlying the interaction of apricot bud gall with its parasite and provide reliable information for designing valuable breeding programs. This study will be quite useful for pest management and will provide a comprehensive evaluation of ecology-based cost-effective control, life history and demographic parameters of A. phloeocoptes.

Apricot bud gall mite, Acalitus phloeocoptes (Nalepa), is a destructive arthropod pest that causes significant economic losses to apricot trees worldwide. The current study explores the ways to understand the mode of dispersal of A. phloeocoptes, the development and ultrastructure of apricot bud gall, and the role of phytohormones in the formation of the apricot bud galls. The results demonstrated that the starch granules in the bud axon were extended at the onset of the attack. During the later stages of the attack, the cytoplasm was found to deteriorate in infected tissues. Furthermore, we have observed that the accumulation of large amounts of cytokinin (zeatin, ZT) and auxin (indoleacetic acid, IAA) led to rapid bud proliferation during rapid growth period, while abscisic acid (ABA) controls the development of gall buds and plays a vital role in gall bud maturity. The reduction of gibberellic acid (GA3) content led to rapid lignification at the later phase of bud development. Overall, our results have revealed that the mechanism underlying the interaction of apricot bud gall with its parasite and have provided reliable information for designing valuable Apricot breeding programs. This study will be quite useful for pest management and will provide a comprehensive evaluation of ecology-based cost-effective control, life history and demographic parameters of A. phloeocoptes.

Several mite species attack southern highbush blueberries (SHB), including the southern red mite (Oligonychus ilicis McGregor (Acari: Tetranychidae)), the false spider mite or flat mite (Brevipalpus yothersi Baker) and the blueberry bud mite (Acalitus vaccinii Keifer). The southern red mite is the key mite pest attacking blueberry plants in the southeastern US (Lopez and Liburd 2020). The false spider mite is a secondary leaf feeding mite pest that was reported attacking southern highbush blueberry in 2016 (Akyazi et al. 2017). This publication discusses southern red mites and flat mites on SHB in Florida, including life cycle, damage, and management practices.

EnglishBlackberry is part of the small-fruit group and the blackberry cultivation area is expanding as an important option for small farmers using the agroecological production system. Mites are prominent among the world’s major crop pests, as they can affect plants from growth to fruiting. The objective of this study was to evaluate the occurrence of phytophagous and predatory mites in different blackberry genotypes in the municipality of Pelotas, RS, Brazil. This study was carried out in the period Nov. 2015 - Oct. 2016, totaling 14 samples. A total of 11,158 mites were collected [phytophagous (5940) and predatory (323) mites, and those with varied feeding habits (4895)], which were distributed in 8 families. The species Neotetranychus asper (Feres & Flechtmann, 2000), Diptacus rubuscolum (Trinidad, Duarte & Navia, 2018), and Acalitus orthomerus (Keifer, 1951) had highest occurrence. According to the faunistic classification, the N. asper phytophagous species is predominant in genotypes 128 and 178; whereas, D. rubuscolum is predominant in genotype 132. Monitoring of these genotypes is recommended to detect possible damage to the crop. Key words: Rubus spp.; faunistic analysis; phytophagous; predators. portuguesA amoreira-preta faz parte do grupo das pequenas frutas e sua area de cultivo esta em plena expansao, sendo uma opcao importante para os pequenos agricultores que usam o sistema de producao agroecologico.

Acalitus vaccinii (Keifer, 1939) is reported for the first time in South Africa, on cultivated blueberries (Ericaceae: Vaccinium spp.). This is the first known occurrence outside its likely native range in North America where it is a pest on cultivated and wild blueberries. In South Africa it has first been identified in 2014 and now occurs between Amsterdam and Lothair, and near Lydenburg and Dullstroom in the Mpumalanga Province. The morphology of the South African A. vaccinii specimens was compared with previous published taxonomic descriptions and differences were found. Infestation levels in South Africa were high, and reduced flower and berry formation considerably on various Vaccinium corymbosum L. cultivars, and on rabbiteye blueberry Vaccinium virgatum Aiton. 'Centurion'. The current status of, symptoms, and cultivars infested by the mite in South African blueberry plantings are presented and discussed in the context of published information in North America. Acalitus vaccinii is a potential threat to cultivated blueberries in South Africa, but the threat varies according to climate and the susceptibility of different cultivars to this mite. Acalitus vaccinii will unlikely infest South Africa’s indigenous vegetation, apart from possibly the native Vaccinium exul Bolus.

For the first time, Tetranychus ludeni Zacher and Acalitus orthomera (Keifer) were reported in addition to T. urticae Koch in cultivated blackberries, Rubus fruticosus L., at Zapotitlan de Vadillo, Jalisco, Mexico. A total of 219 organisms were collected, 40 specimens of A. orthomera, 117 of T. ludeni and 62 of T. urticae. Current distribution of the species in the country and damage to cultivation were discussed.

An invasive East Asian rust fungus Melampsoridium hiratsukanum, obligate biotroph belonging to Pucciniastraceae, Pucciniales (Basidiomycota) is found widely spread on leaves of Alnus incana in eastern, central and southern parts of Lithuania. On Alnus glutinosa this fungus is rare, sometimes occurring with an alder leaf pest, a microscopic eriophyid gall mite Acalitus brevitarsus. Information on the distribution patterns, ecological and morphological characters of this neomycete is given.

A new vagrant species of Diptilomiopidae mite, in the Diptacus Keifer, 1951 genus, namely Diptacus rubuscolum sp. nov., living on the lower leaf surface of blackberry-Rubus sp. (Rosaceae) in South Brazil, is described and illustrated. In addition, Acalitus orthomerus Keifer, 1951, for the first time reported in Brazil and even in South America; a supplementary description of this species is presented based on females, males and immature specimens associated to the drupelets. Main morphological differences distinguishing the new Diptacus species and A. orthomerus species from those belonging to the same genera or morphologically similar also associated with Rubus are presented.

Two new species of eriophyid mites (Acari: Prostigmata) viz. Cosetacus sharadi n. sp., collected from leaf erineum on Cordia dichotoma (Boraginaceae), and Acalitus delhiensis n. sp., collected from leaf erineum on Salvadora persica (Salvadoraceae), are described from India. Cosetacus sharadi has divided feather claw, each branch comprising of 4–5 rays, shield with median line present from rear to mid, admedian lines parallel to median line till mid, then bulging out meeting at the anterior end, submedian lines present from anterior to mid, epigynium ribbed in 2 ranks, accessory seta absent, antapical seta present. Acalitus delhiensis has 7 rayed simple feather claw, shield with median line present in rear to mid, admedian and submedian lines branched, epigynium coarsely granulated, accessory seta and antapical seta absent.

Acalitus essigi, the eriophyoid mite that causes red berry disease in Rubus species (Rosaceae), was collected from the fruits of three species of weedy blackberry, R. anglocandicans, R. laudatus and R. ulmifolius, in south-west Australia. This is the first record for this species in Western Australia and these plants appear to be new host records for A. essigi, which causes uneven ripening of fruit. Information on the mite is reviewed in the context of determining its potential as a biological control agent for Rubus species, especially those that are not susceptible to Phragmidium violaceum (Uredinales), the rust fungus being released against species of European blackberry in Australia. Published records also show that A. essigi will attack a wide range of Rubus species including species of North American origin that currently escape biological control in Australia. It may also be useful for preventing the spread of commercial varieties of Rubus (e.g. raspberry and loganberry) that have escaped to become weedy. However, the mite may have limited dispersal ability and thus require redistribution.

Six species of spider mites (Tetranychidae), Oligonychus biharensis (Hirst), O. modestus (Banks), O. psidii Flechtmann, Tetranychus gloveri Banks, T. mexicanus (McGregor), T. urticae Koch; three species of false spider mites (Tenuipalpidae); Brevipalpus phoenicis (Geijskes), B. styxus De Leon, B. trinidadensis Baker; three speeies of eriophyid mites (Eriophyidae), Acalitus cracens Flechtmann and Etienne, Calacarus capsica Chakrabarti and Mondal, Paraphytoptus intersitus Flechtmann and Etienne; and one species of snout mites (Bdellidae), Bdella distincta Baker and Balock are reported from Guadeloupe and Les Saintes. Oligonychus modestus (Banks) is redescribed.

Two new species of eriophyid mites, Acalitus alnusae n. sp. from Alnus glutinosa (L.) Guertin. and A. subcordata (L.) C.A. Meyer (Betulaceae), and Aceria castaneifoliae n. sp. from Quercus castaneifolia C. A. Meyer (Fagaceae), are described from Iran. The new species are compared with related species and illustrated. Additionally, two new records of eriophyid mites from Iran are given. They are Aceria geranii (Canestrini) and Aceria pterocaryae Kuang and Gong.

Acalitus sp. (Eriophyidae) induces the formation of galls on terminal buds of the deciduous tree Carpinus tschonoskii Maxim., and some phytoseiid mites inhabit these galls. Seasonal occurrence of Acalitus sp. and phytoseiid mites on C. tschonoskii was observed in central Japan, and the role of the gall as a habitat for phytoseiid mites was evaluated. A large number of phytoseiid mites overwintered in the galls. In spring, phytoseiid mites appeared on the galls and preyed on Acalitus sp. The phytoseiid mites readily oviposited eggs on and/or in the galls and reproduced. These results suggest that the galls provide beneficial habitat for phytoseiid mites and that galls as well as leaves, may be important arboreal habitats of phytoseiid mites.

The goal of this study was to evaluate potential alternatives to endosulfan for control of the blueberry bud mite (Acalitus vaccinii), because the availability of this acaricide may be restricted in the future. Laboratory evaluations of potential acaricides showed that endosulfan and a combination of abamectin plus oil provided 97% and 100% control, respectively. Pyridaben and fenpropathrin were less effective, reducing mite survival by 49% and 57%, respectively. Further laboratory evaluation of the abamectin plus oil treatment showed that each component applied alone provided a high level of control of blueberry bud mite. Field trials in Michigan on a mature highbush blueberry (Vaccinium corymbosum) planting were conducted to compare control of this pest by postharvest applications of endosulfan, delayed-dormant application of oil, or a combination of both treatments. The oil provided a 40% reduction in mite scores, while endosulfan was more effective (48%) and similar to the combination of endosulfan and oil (52%). A separate field trial using a multifan/nozzle sprayer that applied the pesticide in 233.8 L·ha-1 (25 gal/acre) of water suggested that the level of control from one application of endosulfan was not as effective as two applications. Results are discussed in relation to developing future bud mite control programs in blueberry and the need to address gaps in our understanding of the biology of blueberry bud mite. Endosulfan (Thiodan 50 WP), Endosulfan (Thiodan 3 EC), Abamectin (AgriMek 0.15 EC), Fenpropathrin (Danitol 2.4 EC), Pyridaben (Pyramite 60 WP).

A new species of eriophyoid nothopodine mite from Australia is described and illustrated. Floracarus perrepae n. sp. causes leaf curling of the Old World climbing fern, Lygodium microphyllum (Cav.) R. Br. and Lygodium reticulatum Schk. (Schizaeaceae) in Queensland. This species was also collected from L. microphyllum in China and New Caledonia and is the first record of the genus from Australia. Ten eriophyoid species new to the Australian fauna are recorded: Oxycenus maxwelli (Keifer) on olive, Olea europaea L.; Epitrimerus pyri (Nalepa) on pear, Pyrus communis L.; Cisaberoptus kenyae Keifer (also a new record for West Timor, Indonesia), Neocalacarus mangiferae Channabasavanna and Tegonotus mangiferae (Keifer) on mango, Mangifera indica L.; Diptilomiopus assamica Keifer on citrus, Citrus limon (L.) Burm. f.; Acalitus essigi (Hassan) on blackberry, Rubus fruticosus L.; Aceria magnoliae (Keifer) on yulan tree, Magnolia denudata Desr.; Aceria fraxiniflora (Felt) on golden ash tree, Fraxinus sp. and...

The eriophyoid mite, Acalitus essigi (Hassan), is hypothesised to be responsible for redberry disease of blackberry (Rubus fruticosus L. agg.) fruit. Infested fruit ripen unevenly with affected drupelets becoming hard, inedible and bright red, whereas unaffected drupelets ripen evenly. As a first step toward possible control of this disease, the method and timing of dispersal of A. essigi onto developing blackberry fruit was examined. No mites were found on unopened flower buds or open flowers. However, infestation of fruit was found to commence during the green stage of fruit development and significantly increase during the red fruit stage. Although redberry symptoms were not observed, experimental exclusion of A. essigi to prevent the mite moving up the pedicel of open flowers by a sticky barrier significantly reduced A. essigi populations within the resultant fruit by over five fold that of control fruit. Although very low levels of aerial dispersal onto fruit cannot be discounted it was concluded that non-aerial or crawling dispersal via the fruit pedicel was the dominant method of blackberry fruit infestation.

Specialised phytophagous arthropods often display high levels ofspecificity to particular sites on their host plant. In this paper we examinethe occupation of microhabitats and aggregation patterns of the eriophyoidmite,Acalitus essigi (Hassan), on its host plant, Europeanblackberry (Rubus fruticosus L. aggregate), a plant thatundergoes significant seasonal changes in its morphology. A.essigi was found to be a refuge inhabiting species. It resided inbudand leaf axil microhabitats on both primocanes and fructocanes and alsooccupiedberry and bract microhabitats on fructocanes. Population fluctuations withinthedifferent microhabitats were evident across seasons. From summer to winter,populations significantly declined in bract and leaf axil microhabitats, butsignificantly increased within bud microhabitats where overwintering took placeas slowly reproducing colonies. Live fruit and young shoots were alsoidentifiedas overwintering sites. A. essigi populations displayed anaggregated distribution both within and between individual blackberry canes.Within primocanes A. essigi were aggregated in the lower20% of cane length. On fructocanes aggregation of A.essigiwas in the lower 20% and especially in the upper 20% of cane length. In springA. essigi was confirmed to emerge from bud overwinteringsites and colonise shoots mainly in the lower third of the previousseason's primocanes, suggesting limited dispersal away from overwinteringsites. It is proposed that biotic factors such as tissue age, microhabitatmorphology and limited ambulatory dispersal capabilities are responsible fortheaggregation patterns of this mite.

Some spider mites (Tetranychidae), false spider mites (Tenuipalpidae) and eriophyid mites (Eriophyidae) are reported from the French Antilles of Guadeloupe, Les Saintes, and French Guyana. Two new species of eriophyid mites, Acalitus granulatus and Paraphytoptus intersitus, are described. Aceria chrysophylli (Cook, 1906) is redescribed from Guadeloupe.

Four new species of eriophyid (Acari: Prostigmata) are described from Trema micrantha (L.) Blum., Ulmaceae, in Brazil, viz: Acalitus tanysetus n. sp., Tegolophus apheles n. sp., Shevtchenkella gnatholoba n. sp. and Vimola (?) paucisetosa n. sp. Hypostomal or infracapitular lobes are described from S. gnatholoba as well as a minutive solenidion-like structure on the dorsum of tibia I which is probably homologous with solenidion phi (⊘) of other Prostigmata.

Aculops emblemus n.sp. and Acalitus carbonis n.sp. (Acari: Eriophyidae) are described from leaf erineum galls on Sclerolobium paniculatum Vog. (Caesalpiniacea) from Central Brazil.

Acalitus delhiensis Menon, Joshi & Ramamurthy, 2009: 65 — Holotype female (IARI), from Salvadora persica (Salvadoraceae), Iari, New Delhi, India., Published as part of LIU, DONG, YI, TIAN-CI, XU, YUN & ZHANG, ZHI-QIANG, 2013, new mite species described during 2007 to 2012 3663, pp. 1-102 in Zootaxa 3663 (1) on page 39, DOI: 10.11646/zootaxa.3663.1.1, http://zenodo.org/record/5630595

Two new eriophyid mites from Brazil are described: Distaceria ommatos, n. g., n. sp., and its alternate form, both with conspicuous eye-like structures, and Acalitus accola. Both mite species were collected from the same leaves of an unidentified small Rubiaceae tree, with galls on the upper surfaces and erineum on the lower surfaces.

In this study the effectiveness of the sticky tape method of eriophyoid mite extraction (Harvey and Martin, J. Econ. Entomol. 81, 731–734, 1988) was evaluated with and without the addition of a new method – a supplementary synthetic pyrethroid spray – for estimating the critical abundance of eriophyoid mites from within architecturally complex plant structures. To do so the eriophyoid mite, Acalitus essigi (Hassan) was sampled from within the architecturally complex fruit of blackberries (Rubus fruticosus L. aggregate). Even though damage symptoms were not observed, sticky tape extraction supplemented with a synthetic pyrethroid spray was the significantly most successful method of mite extraction, with on average over twice the number of mites extracted from blackberry fruit using this method compared with sticky tape alone. Visual counts of A. essigi on the receptacle region of blackberry fruit were correlated to the number of mites extracted using the sticky tape method both with and without a spray treatment. However, due to the low numbers that were visually assessed, the use of visual methods alone appears limited.

A new vagrant species of eriophyoid mite, Asetadiptacus acarubri n. sp., is described and illustrated from Rubus fruticosus (Rosaceae) in Britain, a key to the world species of Asetadiptacus is provided, and Anthocoptes rubicolens Roivainen and Trimeroptes rubi Bagdasarian are recorded from Britain for the first time. In addition, Acalitus essigi (Hassan) and Phyllocoptes gracilis (Nalepa) are reported from R. fruticosus and Rubus sp., respectively. Collection details, distribution and host plant symptoms are provided, together with digital micrographs of the prodorsal shield and coxigenital region of a female from each species discussed. A review of the other eriophyoid mite species hitherto recorded in Britain from Rubus is also provided.

Acalitus essigi (Hassan, 1928) (Fig. 1) Type host and locality. Hassan (1928) had not clearly specified the type host or locality but stated that A. essigi was first reported by Essig and Smith (1922) on Himalaya blackberry in California, USA. Keifer (1941) redescribed this species from Rubus vitifolius Cham. & Schlechtendal collected in Sacramento, California, to ���definitely characterize the red-berry mite���. Distribution. Widespread in Europe and the USA and also recorded from Australia, New Zealand, and Chile on many species of Rubus. Relation to the host. The feeding activity of A. essigi is the causal agent of ���red berry disease���, which results in incomplete, uneven ripening of the fruit, and is a particular problem for late maturing varieties (de Lillo & Duso, 1996). Collection data. England, Norfolk, Norwich, commercial plant nursery site, low numbers of adult females and males on R. fruticosus, 26.viii. 2009; England, Kent, Tonbridge, commercial plant nursery site, low numbers of adult females, males and nymphs on R. fruticosus, 07.x. 2009 and 12.xi. 2009. Remarks. The first record of eriophyoid mites causing ���red berry disease��� in England appears to have been made by Massee (1931), who recorded damage from East Malling, Kent, and Kirdford, West Sussex, and listed the host plants as wild and cultivated blackberries, loganberry and Himalaya berry, but did not provide any specific plant names. Massee (1961) confirmed A. essigi from slide mounted specimens and reported it from Rubus spp. from East Malling, Preston, Lancashire and Southfleet, Kent, and reported it as ���locally common���., Published as part of Pye, Daniel R. L. & Lillo, Enrico De, 2010, A review of the eriophyoid mites (Acari: Eriophyoidea) on Rubus spp. in Britain, with a new species (Diptilomiopidae) and two new records, pp. 15-26 in Zootaxa 2677 on pages 16-17, DOI: 10.5281/zenodo.199254, {"references":["Hassan, A.

Seven species of plant mites are reported from Guadeloupe: two spider mites, Oligonychus biharensis (Hirst) and Tetranychus mexicanus (McGregor), Tetranychidae; one false spider mite, Brevipalpus phoenicis (Geijskes), Tenuipalpidae; two eriophyid mites, Colomerus bucidae (Nalepa) and Ectomerus triquetrus Flechtmann & Etienne, Eriophyidae; two phytoseiid mites, Amblyseius largoensis (Muma) and Iphiseiodes zuluagai Denmark & Muma, Phytoseiidae; and, four new species of eriophyid mites, namely Acalitus cracens n. sp. from Turnera subulata Smith (Turneraceae), Aceria doliolum n. sp. from Haematoxylon campechianum L. (Caesalpiniaceae), Eriophyes gallitor n. sp. from Sideroxylon obovatum (Lam.) (Sapotaceae) and Vasates caritus n. sp. from Haematoxylon campechianum L. (Caesalpiniaceae).

Chromolaena odorata is a neotropical plant introduced to humid tropical Asia and Africa in the mid 1800 s. In the mid 1900s it became a weed problem in West, Central and Southern Africa, South and Southeast Asia and Micronesia. It is highly allelopathic and fire prone. It invades disturbed forests, vacant lands, wildlife reserves, riverbanks, pastures and plantation crops. Mechanical and chemical methods of controlling this weed are expensive and require repeated operations. Classical biological control has been implemented in several countries. The natural enemies Pareuchaetes pseudoinsulata and Cecidochares connexa have been successfully introduced to several countries in Asia and Micronesia with positive results. Another natural enemy, Acalitus adoratus has been fortuitously introduced to Asia and Micronesia. The South African biotype of chromolaena is different from the biotype that invaded the rest of the world and the natural enemies which proved effective on the later biotype do not thrive on the former. The origin of the biotype of chromolaena in South Africa has been narrowed down to northern Caribbean region. Natural enemies from this region are being screened in South Africa.

J. Etienne, 4 Aug. 2001, on 7 microscopic preparations in the collection of Departamento de Entomologia, Fitopatologia e Zoologia Agrícola, Universidade de São Paulo, ESALQ, Piracicaba, São Paulo, Brazil. One paratype slide deposited in the New Zealand Arthropod Collection. RELATION TO HOST ­ vagrant on lower leaf surface. ETYMOLOGY ­ The specific designation, simplex, is from the Latin simplex meaning simplicity and refers to the reduced prodorsal shield design. REMARKS ­ One species of Acalitus, A. ruelliae (Channabasavanna, 1966), described from Ruellia patula in India, was reported on R. tuberosa from Venezuela (Boczek & Nuzzaci, 1988) and from Guyana (Mohanasundaram & Muniappan, 1990). A. simplex n.sp. differs in being much larger (A. ruelliae 115­125 long); in presenting a granulated epigynium (with longitudinal scorings in A. ruellia) and in the anteriorly rounded prodorsal shield (triangular, acuminate in A. ruelliae).
