Population dynamics, native parasitoids and incidence of Tephritidae (Insecta, Diptera) in cherimoya (Annona cherimola mill.) secondary forests at Southern Ecuador

Abstract

Cherimoya is native to southern Ecuador, where it occurs in secondary forests with a high pest incidence, mainly fruit flies. In this research, five McPhail traps baited with Süsbin® 10% were installed in four cherimoya forest, from December 2017 to April 2018, and fruits were collected during the fruition phase to extract the larvae. A total of 1083 Tephritidae individuals and 3613 pupae were obtained from traps and fruits, respectively. Nine species of Anastrepha, one species of Toxotrypana and two parasitoid species were identified. The most abundant species in traps and the only one obtained from fruits was A. fraterculus.
