Abstract

This study assessing the infestation rate of fruit fly species on Solanum aethiopicum, Solanum lycopersicum, and Capsicum spp, using incubation method, was conducted in Agricultural entomology laboratory of Research Centre in Natural Sciences (CRSN) Lwiro, at Kabare in The South Kivu Province in eastern part of the Democratic Republic of Congo. Five species of Tephritidae flies observed, i.e. Bactrocera dorsalis, B. latifrons, Dacus bivitatus, Ceratitis capitata, and Zeugodacus Cucurbitae. The highest infestation rate was observed on B. dorsalis and following C. capitata in those solanaceous chilli pepper (C. frutescens), eggplant (S. aethiopicum) and tomato (S. lycopersicum) than Z. cucurbitae, B. latifrons and D. bivittatus.
