The objective of this research was to evaluate the potential of Lonchocarpus nicou Aublet root powder for management of Neoconocephalus sp (Orthoptera: Tettigoniidae). Fresh roots of L. nicou collected from Ecuatorian Amazonia were processed. Under laboratory conditions, the lethal toxicity of the root powder on adults was evaluated. A random design with five repetitions was used to evaluate the dosage of 6, 25 g. l-1; a negative control was included and the results were processed by a comparison of proportions. The L. nicou root powder showed a lethal toxic effect on adults of Neoconocephalus sp. Inanition, uncoordinated movement, paralysis and 70 % of insect mortality was observed after 6 hours. Population death of 100 % after 24 hours with statistically significant differences compared with the control was found. Based on the high toxicity on adults, the root extract of L. nicou shows potential to be developed as pesticides intended for management of Neoconocephalus sp. [ABSTRACT FROM AUTHOR]

Periodic sampling and nocturnal collections by light traps were carried out in localities of Matanzas and Ciego de Avila provinces, Cuba, between January 2021 and February 2022, to detect the presence of burrowing bugs. Very small bugs with brownish body color were observed. The morphology of the adults under a stereoscopic microscope was described. External genitalia of both sexes were dissected; parameres and spermatheca were carefully removed, immersed in 10 % KOH solution for clarification and mounted on slides. Digital photographs were taken at 40x magnification with a Nikon camera coupled to an Olympus N-800 photomicroscope. Morphometric descriptions of the species and internationally available taxonomic keys for the genus were used for identification. A detailed description of male and female genitalia of Amnestus basidentatus Froesch is offered for the first time. Photographs of paramere and spermatheca, which allowed a precise taxonomic diagnosis of the species in the country, are provided. [ABSTRACT FROM AUTHOR]

The aim of the present research was to evaluate the agroproductive response of chickpea (Cicer arietinum L.) under different soil humidity conditions. For that purpose, an experiment was carried out in areas of the UBPC "El Sordo", municipality Martí, Matanzas. Three treatments were studied: control (the watering was applied to indicate the Technical Handbook for the cultivation of chickpea on the Cuba conditions), unirrigated conditions and unirrigated + Trichoderma sp. At the moment of harvest, it was determined the number of legumes per plant, number of empty legumes per plants, number of seeds per legumes, number of seeds per plant, weight of 100 seeds (g) and yield (t ha-1). A total randomize design was used and data was processed with the statistic software STATGRAPHIC plus 5.1. The analyzed treatments affected the yield and their attributes on chickpea, variety JP 94. Control (with watering) showed the best response. The application of TRICOSAVE 34 based on Trichoderma harzianum strain A-34 unirrigated, did not increased the yield parameters evaluated.

The efficacy of Diatomaceous Earth (Protect IT ®) was tested for the control of Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae) in a metallic silo of Matanzas province, Cuba. A random design was arranged and three groups were evaluated: Protect IT (90% of diatomaceous earth), a positive control (Actellic CE 50) and an untreated control. The diatomaceous earth and Actellic were evaluated at 9.0 kg PC. ton - 1 and 12.0 ml. ton - 1, respectively. The dose of Diatomaceous Earth tested showed insecticide activity with 100% mortality percentage during the first 60 days, without statistical differences with the Actellic insecticide. After three months, the insect mortality was 60%, with statistical differences with the chemical insecticide. The results suggest the potentialities of Diatomaceous Earth (Protect IT ®) as an alternative for management of S. zeamais in metallic silos and for reducing the use of chemicals in corn grain storage.

Tourism is a key to develop the Cuban economy, and Varadero has an important role in the international market. The Varadero Golf Club is located in an attractive landscape of the Hicacos Peninsula and golf practice is a tourism product which complements that sun and beach destination. The objective of this study was to describe the incidence of pest insects and their repercussions on the green aesthetics and golf practice in the tourist attraction. The results showed that the turfgrass aesthetics is affected by insects belonging to the Lepidoptera, Coleoptera, Hymenoptera and Hemiptera orders, and that the green keepers need more technical training related to the pest problem. Thus, it is necessary to adopt integrated pest management strategies that allow to maintain the green quality and the tourists' satisfaction during the golf game. [ABSTRACT FROM AUTHOR]

A study was conducted in order to determine the main species of rhizophagous insects associated to the turfgrass varieties in the Varadero Golf Club (Matanzas, Cuba). During 2010-2015 root samples from the turf of varieties Bermuda grass 328 and tifdwarf (hybrids obtained from Cynodon dactylon (L.) Pers x Cynodon transvaalensis Burtt-Davy) were evaluated, which were extracted through a hole-cutting device. In them the main associated rhizophagous insects were collected and the lesions were identified and described. Thirteen insect species were found, corresponding to five orders and eight families, which were found in all the game areas (except in the rough); the taxa with higher incidence belonged to the orders Hemiptera and Coleoptera. Due to the affectations they caused on the turf of both hybrids the burrower bugs Dallasiellus varaderensis Marrero and Mayorga, Tominotus inconspicuus Froeschner and the true weevils Sphenophorus sp. (1) and Sphenophorus sp. (2) stood out; proving their potential as pest insects of the turf in Cuba for the grasses of the Cynodon genus, because the root affectations caused chlorosis, burns and localized death of the turfgrass in the Varadero Golf Club. As a result of the inventory conducted the recording, for the first time, of the two species of the Sphenophorus genus stands out. It is recommended to identify the Sphenophorus species and to include them, along with D. varaderensis and T. inconspicuus, in the available list of the insect species associated to turfgrasses in the country.

Areas of production at the Livestock Enterprise of Marti in Matanzas province, Cuba were sampled from December 2013 to February 2014 to determine the species of noxious insects associated with the chickpea crop (Cicer arietinum L.). Nine species belonging to three orders and families were found, among which Anticarsia gemmatalis Hubner and Euschistus sp. were reported for the first time for the crop. Helicoverpa zea Hubner showed the highest frequency of occurrence and caused serious damages on pods and grains; thus, it was recognized as the main pest affecting this crop in our province.
