Abstract

Tropical forest canopies are unique environments with complex interactions, allowing for high levels of specialization for insects. The purpose of this study was to test whether increased specialization has created differences in species richness and diversity between nocturnal and diurnal canopy insects. To test this, insects were collected from six trees using suspended traps containing three types of bait (carrion, rotten fruit, and specific scents that attract euglossine bees). Diversity and species richness was quantified for diurnal and nocturnal traps of all three baits and for total number of insects collected diurnally and nocturnally. The results showed that on all accounts there was a significant difference in species richness and diversity for diurnal traps (H’ = 1.000) and nocturnal traps (H’ = 0.863) (P = 0.005). Diurnal traps had a significantly higher overall abundance, species richness, and diversity than nocturnal traps. Los doseles de los bosques tropicales son ambientes únicos con interacciones complejas, que permiten altos niveles de especialización en los insectos. El propósito de este estudio fue determinar si la mayor especialización ha creado diferencias en la riqueza y diversidad en los insectos nocturnos y diurnos del dosel. Para probar esto, los insectos fueron colectados en seis árboles usando trampas suspendidas que contenían tres tipos de cebo (carroño, fruta podrida, y olores que atraen abejas euglosines). Se cuantificó la diversidad y riqueza de especies en las trampas diurnas y nocturnas con los tres cebos y para las trampas diurnas y nocturnas en total. Los resultados demostraron que en todos los casos había una diferencia significativa entre la riqueza y la diversidad de las trampas diurnas (H’ = 1.000) y las trampas nocturnas (H’ = 0.863)(P = 0.005). Las trampas diurnas tenían una abundancia, riqueza, y diversidad significativamente más altas que las trampas nocturnas.
