1. Dormancy of a specialist herbivore, Anthonomus rufipennis (Coleoptera: Curculionidae), in a dry tropical forest.

Abstract: The life history aspects of dormancy of the weevil Anthonomus rufipennis LeConte (Coleoptera: Curculionidae) were studied a 57-month period in a seasonally dry tropical forest of central Mexico. Weevil populations and their physiological status were monitored on both the reproductive host tree, Senna polyantha (Collad.) H.S: Irwin & Barneby (Fabales: Fabaceae) and the highly favored refuge host, Tillandsia recurvata L. (Poales: Bromeliaceae) or "ball moss." During the dry season, weevils were only found on the refuge host with a mean total density of 1.014 ± 2.532 individuals/ball moss (N = 1,681). Weevil densities on T. recurvata between early and late dry seasons were not significantly different, suggesting that dry season survival was relatively high. Weevils collected during these seasons revealed little reproductive development and relatively high-fat accumulation in both sexes. During 5 of 6 yr, densities of the weevils in T. recurvata dropped significantly during the early rainy seasons, when the reproductive host trees leafed out and began producing oviposition sites (flower buds). At this time, more males than females initially moved to vegetative trees and showed significant signs of reproductive development. Recolonization of ball moss by weevils began during the late rainy season when oviposition sites (flower buds) were still available. A proportion of the weevils remained on the reproductive host, suggesting that A. rufipennis is facultatively multivoltine. The methodologies and results of the study can serve as a model system for future studies of the dormancy of other insects in dry tropical forests and provide insight into the dormancy of other anthonomine weevils of economic importance.

Abstract: Simple Summary: The boll weevil (Anthonomus grandis Boheman) (BW) is one of the most well-known and historically important insect pests in the Americas. Presently it is a key pest of cotton in Mexico and Central and South America. In the United States, a successful area-wide pest management program has eradicated the pest from nearly the entire country, except for the Lower Rio Grande Valley region of extreme southern Texas. Eradication in the US has been successful, in part, because the insect can only develop on a narrow range of host plant species besides cotton, none of which occur outside of Texas and Arizona. However, wild host plants are an important consideration for management of this pest in regions where they are present and for preventing reinfestations in areas where eradication has been successful. Here, we present the first detailed analyses of the potential distributions of all known significant wild host plants of the boll weevil in the United States and Mexico. These analyses will enable management to better evaluate the role of wild host plants in their management areas, improve existing boll weevil eradication strategies, and provide insights into the evolutionary history of this important pest insect. The boll weevil (Anthonomus grandis Boheman) reproduces on a reported 13 species of wild host plants in North America, two in the United States and 12 in Mexico. The distributions of these plants are of economic importance to pest management and provide insight into the evolutionary history and origin of the BW. However, detailed information regarding the distributions of many of these species is lacking. In this article, we present distribution models for all of the reported significant BW host plants from Mexico and the United States using spatial distribution modelling software. Host plant distributions were divided into two groups: "eastern" and "western." In Mexico, Hampea nutricia along the Gulf Coast was the most important of the eastern group, and the wild cottons, Gossypium aridum and Gossypium thurberi were most important in the western group. Other species of Hampea, Gossypium, and Cienfuegosia rosei have relatively restricted distributions and are of apparent minimal economic importance. Cienfuegosia drummondii is the only truly wild host in the southern United States, east of New Mexico. Factors determining potential distributions were variable and indicated that species were present in five vegetation types. Ecological and economic considerations of host plant distributions are discussed, as well as threats to host plant conservation. [ABSTRACT FROM AUTHOR]

Abstract: Mexico is a center of New World crop origins with many insect species associated with the wild crop relatives, some of which have become pests of cultivated plants. Many of these indigenous pests of Mexico are weevils (Coleoptera: Curculionidae), and some represent potential quarantine pests. In the present work, we present some of the most important species of weevils considered as crop pests, which are presently restricted primarily to Mexico with the potential to invade other regions. We also present species of weevils exotic to Mexico, considered by national quarantine authorities to be possible threats to Mexican agriculture. Potential quarantine weevil pests for avocado include Conotrachelus aguacatae Barber, Conotrachelus perseae Barber, Heilipus lauri Boheman, Heilipus albopictus Champion, and Copturus aguacatae Kissinger (all Coleoptera: Curculionidae). For guava, species include Conotrachelus dimidiatus Champion and Conotrachelus copalensis Salas-Araiza and Romero-Nápoles (both Coleoptera: Curculionidae). Weevil pests reported with quarantine importance for sugar cane are Sphenophorus incurrens Gyllenhal (Coleoptera: Dryophthoridae), Apinocis angustus (Casey), and Apinocis subnudus (Buchanan) (both Coleoptera: Curculionidae). The weevil Rhyssomatus nigerrimus Fåhraeus (Coleoptera: Dryophthoridae) recently has been observed damaging soybeans in northern and southern Mexico. Cactophagus spinolae Gyllenhal (Coleoptera: Dryophthoridae) is a generalist cactus pest. Scyphophorus acupunctatus Gyllenhal (Coleoptera: Dryophthoridae) is a well-known pest of cultivated and wild agaves. Several species of Epicaerus (Coleoptera: Curculionidae) have been reported on various crops in restricted areas including, among others, Epicaerus operculatus (Say) on garlic, and Epicaerus cognatus Sharp (both Coleoptera: Curculionidae) on potato. Amphidees latifrons (Sharp) (Coleoptera: Curculionidae) has been reported from apples in localized regions of northern Coahuila. Weevils exotic to Mexico of quarantine concern are Naupactus cervinus Boheman, Diaprepes abbreviatus (L.) (both Coleoptera: Curculionidae), and Rhynchophorus ferrugineus (Olivier) (Coleoptera: Dryophthoridae). [ABSTRACT FROM AUTHOR]

Comments. Members of this genus can be confused with other genera of the subtribe Tylodina that also have tuberculate elytra, such as Tylodes, Xenosomus, or Phymatophosus. Species of Tylodinus are most commonly confused with Acalles, because so many species were erroneously originally placed in this genus (Champion 1904, O��Brien and Wibmer 1982); however, the metepisternum of these genera is not externally visible, and this character separates these genera from Tylodinus. Fiedler (1940) placed Tylodinus near Canistes and Pseudoacalles because these genera have the metepisternum distinctly visible, but other characters given in the diagnosis will separate Tylodinus from Canistes and Pseudoacalles. In a forthcoming paper on the phylogenetic relationships of Tylodinus, a number of new genera, closely related to Tylodinus, will be described. Derivation of generic name. C hampion (1905) did not indicate the derivation of the name Tylodinus but it appears to be derived from the combination of two words: Tylodes = derived from Greek �� tylodes �� = tubercle, probably referring to the tubercles on the body of the genus Tylodes and from the Latin suffix inus = like; Tylodinus = like a Tylodes. The name refers apparently to possible confusion between Tylodinus and Tylodes. Natural history. Very few details are available on the natural history of any species of Tylodinus. Adults have been collected almost exclusively in Berlese or Winkler extractions of sifted leaf litter and other ground substrate debris. Some specimens have been collected beating dead vegetation and numbers of larger-sized species have been hand collected on dead wood, apparently in association with Xylariaceae fungi, especially those with the crustose fruiting bodies, which the black, tuberculate body form of the weevil greatly resembles. Immature stages are unknown. Given what is known of the habits of related taxa, it is likely that the larvae mine in dead, decaying wood or other plant debris on the forest floor. Nearly all species are associated with a variety of montane wet forest habitats. Distribution. Tylodinus occur throughout the Sierra Madre Oriental from Tamaulipas south to Panama with many species undescribed. At present, 20 species have been described with an additional 32 species described herein, and numerous other new species from other geographic areas are known. Thus, at present there 52 species known to date, 40 are known to occur in M��xico and of these, 38 species have only been recorded from M��xico and two extend from M��xico south into Central America. As discussed, Tylodinus species in Chiapas are well sampled and were collected at elevations from 1080 to 2970 m in 20 municipalities; the species numbers in these municipalities are detailed in Table 1.

Abstract: 25. Tylodinus complicatus Luna-Cozar, sp. nov. (Figures 24–25, 74-75, 118, 131) Diagnosis. Length male, 2.2-2.5 mm, female, 2.2-2.5 mm. Width male, 1.0- 1.1 mm, female 1.1-1.3 mm. Body approximately 2.1x longer than wide, cuticle sometimes shiny. Head with yellow scales; vertex with dense to contiguous scales, uniformly distributed along vertex, similar in coloration and tonality to scales on head; frons moderately concave; rostrum moderately robust, moderately carinate, apical area puncticulate, eyes moderately convex. Pronotum in dorsal view weakly convex, outline with anterior constriction and without posterior constriction (Figure 10); in dorsal view with sides slightly divergent from base to midlength, then convergent to apex, constricted beyond middle; disc hollowed, punctures dense to contiguous at base and progressively more widely spaced, smaller, shallower to apex, clothed with yellow scales, very dense on lateral sides and flanks, anterior area forming thick longitudinal fringe along middle and narrow strip that diverges from middle base to flanks, with dark brown scales on middle and posterior areas of disc (Figure 14, 74). Elytra black with red coloration on base and along intervals 1-2 and intervals 1-5 on declivity (Figure 74-75), basal margin slightly sinuate (Figure 3), clothed with scattered yellow scales, dense on tubercles on intervals 1-5 at declivity base, and on intervals 1-3 along declivity, stria 10 complete; tubercle distribution as follows: I2 with a small and round tubercle on declivity base, I3 with two tubercles, the first tubercle subbasal, the second tubercle on the middle of elytral declivity, I4 with two small tubercles, first tubercle between tubercles on I3, the other tubercle on declivity base, smaller than tubercle on I2 (but in some specimens of same size), I5 with two small tubercles in same position as tubercles on I3, tubercles on I3 longer than other tubercles, surface without granules. Metasternum flat, glabrous at median section, metasternal teeth absent. Male abdomen with ventrites 3-5 in same plane as ventrites 1-2, ventrite 1 weakly concave, almost flat, glabrous at median section, ventrite 2 as long as 3-4, median section glabrous (Figure 23), female with transverse line of scales interrupted medially (Figure 24), ventrite 5 longer than ventrite 1, flat, with anterior impression. Femora armed, hind femur length reaching elytral apex, middle and hind tibiae subparallel, premucro absent. Male genitalia (Figure 118) with median lobe in lateral view moderately curved, stout; in ventral view as long as half length of apodemes, lateral sides subparallel, convex at sides beyond 0.27 of length from base, apex acute; apical process sinuate, moderately curved downward, small (0.17-0.25 as long as body of median lobe); in ventral view constricted beyond median orifice, rhomboid shape apically (Figure 98e). Female with tergite eight trapezoidal, sternite eight doliform, apex not constricted, median membranous area 2/3 as long as basal plate, spermatheca shallowly curved, ramus indistinct, nodulus slender. Comments. Male genitalia in T. complicatus, T. rufus, T. noctis and T. dominicus are very similar; however, T. complicatus is distinguished from its allies by the small size, elytra coloration and hind tibiae without external teeth.

Abstract: 4. Tylodinus cavicrus Champion 1905 (Figures 34–35, 101, 130) Tylodinus cavicrus Champion 1905: 468, lam. 23, figs. 4, 4 a.; Blackwelder 1947: 860; O’Brien and Wibmer 1982: 139. Diagnosis. Length male, 5.0– 5.9 mm, female, 5.4–5.8 mm. Width male, 2.1–2.8 mm, female 2.7–2.9 mm. In addition to Champion’s description: As for T. pseudocavicrus with the following exceptions: body approximately 2.3x longer than wide. Frons in lateral view slightly concave. Pronotum in lateral view strongly convex, moderately depressed basally and strongly depressed anteriorly. Elytral declivity with I4 tubercle larger than the tubercle of I2. Abdomen of male with ventrite 5 flat in the middle. Male genitalia (Fig 101) with the apical process smaller. Geographic distribution. Guatemala. Habitat and elevation: Specimens have been collected between 2100–2750 m in wet high elevation cloud forest leaf litter and by beating dead branches. Derivation of specific name. Champion (1905) did not indicate the derivation of the specific name cavicrus, but it appears to be derived from two words combined from Latin cavi = hollow, excavated, open; and crus = leg; referring to the peculiar form of the leg. Material examined. Total 30 males, 8 females. Holotype male (BMNH) Guatemala: Quiché Mountains 7000–9000 feet (Champion). Guatemala: El Progresso, 28–29 km N.

The species of this group are distinguished from other Tylodinus by having in combination the body size 2.3 mm or less; pronotum with punctures dense to contiguous at the base and progressively more widely spaced, smaller and shallower to the apex (Figures 14, 16–17); female with the median section of ventrite 2 with a transverse line of scales along midline (Figure 24). Diagnosis. Body 1.9–2.1x longer than wide. Head clothed with yellow scales, punctures similar to punctures on rostrum; vertex with dense to contiguous scales, similar in coloration and tonality to scales on head, uniformly distributed along vertex; rostrum moderately robust, moderately carinate, apical area puncticulate; eyes moderately convex. Pronotum in dorsal view moderately convex, outline with anterior constriction and without posterior constriction (Figure 10); in dorsal view with sides slightly divergent from base to midlength, then convergent to apex, constricted beyond middle (Figure 14); disc hollowed or somewhat hollowed, punctures dense to contiguous at base and progressively more widely spaced, smaller and shallower to apex (Figures 14, 16–17), clothed with yellow scales, very dense on lateral sides and flanks, anterior area and forming thick longitudinal fringe along the middle and narrow strip that diverges from middle base to flanks, and with dark brown scales on middle and posterior areas of disc (Figure 14). Elytra black, basal margin slightly sinuate; tubercle distribution as follows: I2 with a tubercle on the base of declivity, I3 with two tubercles: first tubercle subbasal, second tubercle on middle of elytra, I4 with two tubercles: first tubercle small, positioned between tubercles on I3, second tubercle on base of elytral declivity, similar in size or longer than tubercle on I2, I5 with two tubercles in same position as tubercles on I3. Metasternum moderately concave, glabrous in median section; metasternal tooth absent. Male abdomen with ventrite 1 concave, median section glabrous; ventrite 2 feebly concave, male with median section glabrous, female with transverse line of scales along middle line (Figures 24–25), as long as or longer than ventrites 3–4 combined; ventrite 5 convex along median line, as long as ventrite 1, with an anterior-median impression. Femora armed or unarmed, hind femora length not reaching elytra apex, tibiae subparallel, premucro absent. Male genitalia (Figures 115–116) with the median lobe in lateral view weakly curved, stout or moderately stout; in ventral view as long as or ½ length that of apodeme, lateral sides straight, subparallel or convergent, apex acute; apical process large (0.35–0.42 as long as median lobe), slightly curved; in ventral view not constricted beyond the median orifice, convergent.

36. Insect Diversity of Tropical Montane Forests: Diversity and Spatial Distribution of Weevils (Coleoptera: Curculionidae) Inhabiting Leaf Litter in Southern Mexico.

Author: Jones, Robert W., O'Brien, Charles W., Ruiz-Montoya, Lorena, and Gomez-Gomez, Benigno
Subjects: *BEETLES, *CLOUD forests, *FORESTS & forestry, *BIODIVERSITY, *LEAVES
Abstract: The abundance, diversity, and spatial distribution of the weevil fauna (Coleoptera: Curculionidae) of leaf litter were compared between primary and successional cloud forests at the Biological Reserve Cerro Huitepec in the highlands of Chiapas, Mexico. In total, 2,102 individuals and 57 species of Curculionidae were collected and identified, of which >90% represented undescribed species. Total weevil densities averaged 8.51 ± 9.04 individuals per 0.5 m² of leaf litter. Estimates of the total number of leaf litter weevils in the reserve were >20 million. Data suggest that even small fragments of cloud forest (<10 ha) may maintain viable populations of the more common species of leaf litter weevils for extended periods. However, because of their low powers of dispersion and their high levels of endemism, leaf litter weevils, and presumably other leaf litter insects, are particularly vulnerable to extinction when whole forest fragments are lost or when recent climate changes push cloud forests to higher elevations.

Subjects: *CURCULIONIDAE, *CITRUS, *SPECIES
Abstract: El objetivo del presente trabajo fue conocer la fluctuación poblacional de las especies de picudos en tres sitios con cultivo de limón persa (Citrus latifolia Tanaka) en Huimanguillo, Tabasco, México. Se encontraron cuatro especies de picudos, dos de morfotipos de Epicaerus spp., Exophthalmus opulentus (Boheman 1840), y Cleistolophus subfasciatus (Sharp 1891). La fluctuación poblacional de cada especie fue similar en los tres sitios de estudio. Los morfotipos de Epicaerus spp., se presentaron en altas poblaciones en los sitios 1 y 2, excepto en el sitio 3, donde no se encontraron durante el periodo de estudio. Exophthalmus opulentus y Cleistolophus subfasciatus estuvieron en los tres sitios de muestreo, pero sus poblaciones fueron bajas en comparación con los morfotipos de Epicaerus spp., lo que podría indicar que estos últimos podrían ser más importantes desde el punto de vista económico. The objective of this work was to know the population fluctuation of weevil species at three sites with cultivation of Persian lime (Citrus latifolia Tanaka) at Huimanguillo, Tabasco, Mexico. Four species of weevils were found, two morphotypes of Epicaerus spp., Exophthalmus opulentus (Boheman 1840), and Cleistolophus subfasciatus (Sharp 1891). Their population fluctuation was similar at the three study sites. The morphotypes of Epicaerus spp. occurred in high numbers at Sites 1 and 2, but not Site 3 where they were not found during the study period. Exophthalmus opulentus and Cleistolophus subfasciatus were found at the three sampling sites, but their abundance was low compared to Epicaerus spp. Morphotypes that might indicate the latter could be more important from an economic point of view.

38. Exophthalmus cupreipes Champion (Coleoptera: Curculionidae) in Citrus Crops in Mexico.

Author: Bautista-Martínez, Néstor, Illescas-Riquelme, Carlos Patricio, López-Bautista, Everardo, Jones, Robert W., and López-Buenfil, José Abel
Subjects: *CURCULIONIDAE, *BEETLES, *CROPS, *FOLIAR feeding, *RUTACEAE, *CITRUS
Abstract: Exophthalmus cupreipes Champion (Coleoptera: Curculionidae) adult weevils were detected feeding on young leaves and shoots of Persian limes (Citrus latifolia [Tanaka ex Yu. Tanaka] Tanaka; Rutaceae) in commercial plantations in the states of Veracruz and Tabasco, Mexico. Weevil damage to foliage is apparently not significant enough to cause production losses. However, there are reports of related species included in the Exophthalmus genus complex that are considered primary pests of agriculturally important citruses. This study complements the original description by Champion (1911) for adults of both sexes, and provides images of external and internal structures useful for its identification. Moreover, field observations of damage on citrus are presented, and the potential importance as a pest is discussed. [ABSTRACT FROM AUTHOR]
