Diversidad, fluctuación poblacional y plantas huésped de escolitinos (Coleoptera: Curculionidae) asociados con el agroecosistema cacao en Tabasco, México

Abstract: Se estudió la diversidad de escolitinos asociados con el agroecosistema cacao en Tabasco, México durante el año 2007. Los insectos adultos fueron recolectados en 4 localidades con trampas de alcohol etílico, trampas de atracción luminosa y captura directa sobre sus plantas huésped. Se recolectaron 19 263 ejemplares, pertenecientes a 51 especies y 26 géneros. Araptus hymenaeae y Cnesinus squamosus son nuevos registros para México. La máxima diversidad de insectos capturados con los 3 métodos de recolecta se obt… Show more

“…Besides, the relatively low abundance of Scolytinae subfamily suggests a more or less healthy farm, compared for example to a sampling made in another Venezuelan Criollo cacao plantation, where about 20 Scolytinae were collected per trap [ 22 ]. This group may constitute one of the most important pests in cacao by helping to spread many phytopathogenic fungi [ 64 , 65 ], which have been recorded as the main concern for cacao farmers in Mérida plantations [ 22 ] and have also been associated with the shade trees of cacao agroforestry systems, such as Swietenia and Tabebuia [ 66 ]. However, the lack of complementary collecting methods, such as alcohol traps, light traps, and direct capture, in addition to the seasonal sampling, may be affecting this result [ 66 ].…”

The occurrence of families such as Coccinellidae, Staphylinidae, and Carabidae indicates a community of generalist predator beetles that could be effective at controlling populations of herbivores such as Chrysomelidae, Scarabaeidae, and Elateridae, whereas the low abundance of bark beetle predators such as Histeridae could be related to the low abundance of prey [ 67 ].…”
