Abstract

Insects are a hyperdiverse class, with great relevance in environmental studies, due to the great variety of ecosystem services they provide including regulation, support, provisioning, and cultural services. The objective of this study was to determine the relationship between the types of insect traps and ecosystem services. The evaluation of ecosystem services was carried out in March 2015 using chromatic traps, Van Someren-Rydon, and direct collection in two areas of the San José ecological farm (Citrus and Butterfly). A total of 4918 specimens were found, distributed in 49 families and 191 morphospecies. The most abundant family was Muscidae (55.18%), related to the Van Someren-Rydon trap with decomposing fish, followed by the families Sarcophagidae and Tephritidae. On the other hand, according to the Brillouin index, chromatic traps with attractant were the most homogeneous, while according to the Simpson index no group was predominant at any sampling point. In relation to the trophic position, the most abundant food guild was that of decomposers in Van Someren-Rydon traps with fish bait, with the least abundant being phytophagous and decomposers in direct collections.
