Consumption of insects by birds in guava orchards (Psidium guajava L.)

Abstract

The consumption of insect pests by birds can result in benefits for the farmer. In this sense, the present study aimed to investigate the consumption of insects by wild birds within guava orchards in the upper Sertão Sergipe. The records were conducted from 15 to 30 November 2018, using the direct observation method. 98 feeding events were recorded for 21 bird species. Among the insects consumed by birds, we highlight the caterpillars and bedbugs of the genus Leptoglossus, considered insects harmful to guava. It is possible that birds can reduce the populations of these insects and help with pest control. However, we recommend that experimental studies be performed for confirmation. The results of this research can also be used to change farmers' perceptions of birds, who normally see birds only as animals harmful to crops.
