TL;DR
This study tracks the seasonal activity of six invasive fruit fly species and their host plants in northern Jiangxi, China, to help manage their impact on agriculture.
Contribution
The study reports the first discovery of Bactrocera minax and Callantra trimacula in northern Jiangxi and provides detailed seasonal abundance and host preferences.
Findings
B. minax and C. trimacula were newly recorded in northern Jiangxi.
Zeugodacus tau had the highest population density among the six species.
Different tephritid species showed distinct seasonal peaks and host plant preferences.
Abstract
Several tephritid species have successfully invaded northern Jiangxi, China, posing a serious threat to regional fruit and vegetable production. This study presents a detailed report on the seasonal abundance of six tephritid species and the fruiting phenology of their main hosts across Nanchang, Yongxiu and Xiushui in northern Jiangxi from 2018 to 2021, using data from methyl eugenol (ME), cuelure (CUE), and sugar-wine-vinegar-water (SWVW)-baited traps and from fruits infested by tephritid larvae. A total of 18,875 tephritid specimens were captured by traps, representing six species, Bactrocera dorsalis (Hendel), B. scutellata (Hendel), B. minax (Enderlein), Zeugodacus tau (Walker), Z. cucurbitae (Coquillett), and Callantra trimacula (Wang). Notably, B. minax and C. trimacula were discovered for the first time in northern Jiangxi. In addition to B. minax (captured only in Xiushui)…
