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.

番荔枝原产于厄瓜多尔南部，发生在害虫高发的次生林中，主要是果蝇。在这项研究中，从 2017 年 12 月到 2018 年 4 月，在四个番荔枝林中安装了五个以 Süsbin® 10% 为诱饵的 McPhail 诱捕器，并在果实期收集果实以提取幼虫。从陷阱和果实中分别获得了 1083 只实蝇个体和 3613 只蛹。鉴定出九种按实蝇、一种弓锥虫和两种寄生蜂。陷阱中最丰富的物种和唯一从果实中获得的物种是A. fraterculus。
