Abstract
La diversidad de arañas son parte importante de la fauna benéfica de los agroecosistemas. A pesar de su importancia económica y ecológica en los agroecosistemas, la información disponible en Perú es limitado. Por lo anterior, el conocimiento y el estudio de la biodiversidad se hace necesario para consolidar estrategias de manejo integrado de plagas. El objetivo del estudio fue determinar la diversidad de arañas en el cultivo de cacao orgánico en Tingo María durante los meses de julio 2017 a enero 2018. Las colectas fueron cada 15 días, mediante trampas de caída (20 trampas distribuidos en cinco transectos equidistantes) y búsqueda directa (manual y con paraguas entomológico en 25 árboles de cacao). Se registraron individuos de arañas pertenecientes a 22 familias, las más representativas fueron Lycosidae (80.45 por ciento), Salticidae (11.02 por ciento) y Araneidae (8.21 por ciento). Se identificaron 113 morfoespecies siendo las más abundantes Allocosinae sp. 1 (20.84 por ciento) y Hogna sp. 2 (16.09 por ciento). Los resultados de esta investigación representan la primera contribución al conocimiento de la diversidad de arañas presentes en el cultivo de cacao orgánico en Tingo María, Huánuco.
The diversity of spiders is an important part of the beneficial fauna of agroecosystems. Despite its economic and ecological importance in agroecosystems, the available work in Peru is limited. Therefore, the knowledge and study of biodiversity is necessary to consolidate integrated pest management strategies. The objective of the study was to determine the diversity of spiders in the organic cocoa crop in Tingo María during the months of July 2017 to January 2018. The collections were every 15 days, using pitfall traps (20 traps distributed in five equidistant transects) and direct search (manual and with entomological umbrellas in 20 cocoa trees). Spider individuals belonging to 22 families were recorded, the most representative being Lycosidae (80.45 percent), Salticidae (11.02 percent) and Araneidae (8.21 percent). 113 morphospecies were identified, being the most abundant Allocosinae sp. 1 (20.84 percent) and Hogna sp. 2 (16.09 percent). To our knowledge, this study represents the first contribution to the knowledge of the community of spiders present in organic cacao cultivation in Tingo María, Huánuco.
