Efectividad de cebos en la captura de escarabajos saprófagos (Insecta: Coleoptera) en Allpahuayo Mishana, Amazonía peruana

This study took place from November 2008 to January 2009 in the white-sands forest (locally known as “varillal” or “pole forest”) of the Biological Station José Álvarez Alonso km 26.5 road Iquitos-Nauta Department of Loreto, Peru. Our Objective was to identify the effectivity of different baits when trapping saprophagous beetles in pitfall traps. The following baits were used: Bovine blood (Bos taurus), sugar cane juice (Saccharum officinarum), fermented, ripe banana (Musa x paradisiaca), chicken liver (Gallus gallus domesticus), horse manure (Equus ferus caballus) human feces as well as one bait-less control pitfall trap. A total of 948 individuals were trapped belonging to 24 species. The family with greatest abundance was Scarabaeidae with 939 individuals. Mycetophagidae with 6 individuals, Curculionidae, Cerambycidae and Staphylinidae each represented with one individual. Scarabaeidae richness was represented with 18 species, Mycetophagidae with 3 species and Curculionidae, Cerambycidae and Staphylinidae each represented with one species. The baits with greatest species richness were human feces and cow blood (11 species), the bait with most individual abundance was chicken liver with 242 individuals.
