Abstract

Los escarabajos Melolonthidae (Coleoptera: Scarabaeoidea) ocupan múltiples nichos en los ecosistemas tropandinos. Este grupo incluye miembros con diferentes hábitos alimenticios (saprofagia, fito y zoofagia), lo que aún los posiciona en el ambiente agroindustrial del Valle del Cauca, razón por la cual se planteó determinar la composición y aspectos biocológicos de los escarabajos del plan aluvial monocultivado del Río Cauca (bosque seco tropical Bs-T, 780-1100 mm/año, 960-975 msnm, 24ºC); el estudio biológico incluyó muestreos y observaciones en laboratorio, complementando con revisión de colecciones y literatura; el estudio ecológico (parcelas de caña manejo ecológico (CME), caña convencional (CC), potrero silvopastoril (PSP) y bosque, se basó en cuadrantes (1m2 y 30 cm de profundidad) durante época seca, transición y húmeda. Se aportan datos bioecológicos de las 42 especies consideradas habitantes del plan monocultivado y algunas presumiblemente extintas localmente, estas fueron: Astaena aff. valida, Phyllophaga sericata, P. thoracica, P. impressipyga, Macrodactylus sp., Isonychus sp., Ceraspis sp., Plectris aff. fassli, P. aff. pavida, Pelidnota prasina, Macraspis chrysis, M. nazareti, Paranomala cincta, P. undulata, P. incostans, Leucothyreus femoratus, Cyclocephala lunulata, C. amazona, C. stictica, C. pardolocarnoi, C. melanocephala, Aspidolea fuliginea, Aspidolea singularis, Dyscinetus dubius, Stenocrates bicarinatus, Lycomedes hirtipes, Ligyrus bituberculatus, L. gyas, Coelosis biloba, Podischnus agenor, Strategus aloeus, Parapucaya amazónica, Phileurus valgus, Phileurus didymus, Homophilerus tricuspis, Gymnetis holosericea, G. aff hebraica difficilis, G. pantherina, G. stellata, Hoplopyga liturata, Desicasta reichei y Marmarina maculosa. El estudio ecológico reunió 323 ejemplares y 8 especies, con mayor diversidad (4) y abundancia (18+) en CME y Bosque, observándose los menores resultados en PSP; este reducido ensamblaje se integra de especies preadaptadas al ambiente simplificado, perdiéndose diversidad y valiosos servicios ambientales en los agroecosistemas, por lo que se recomienda enfocar hacía la sostenibilidad el paquete tecnológico del modelo de desarrollo económico implantado.
