Spotted-wing drosophila, (Matsumura), is a worldwide quarantine pest that is currently undergoing a rapid range expansion in the Americas, Europe, and parts of Africa. It feeds and breeds on soft-skinned fruits such as raspberries, blueberries, and cherries, and can cause significant economic losses to fruit production. This study investigated the occurrence of and its wild host fruits and parasitoids in Liaoning, Northeast China for the first time. Sentinel traps were used to monitor adults, and suspected fruits were collected weekly in four different locations (Wafangdian, Faku, Fengcheng, and Shenyang). The results showed that were distributed in the sweet soft-skinned fruit-production areas of Liaoning, and raspberry was the most infested fruit. During the field survey, four species of wild berries from non-crop habitats were found infested by , and two species of parasitoids ( and ) were collected. adult-population dynamics throughout the survey period (June to October) were similar in different survey locations; adult fly populations increased and peaked in August, and then declined until the fly was no longer detectable in October.
斑翅果蝇（Matsumura）是一种世界性检疫害虫，目前正在美洲、欧洲和非洲部分地区迅速扩大其分布范围。它以树莓、蓝莓和樱桃等软皮水果为食并在其上繁殖，会给水果生产造成重大经济损失。本研究首次调查了中国东北辽宁省斑翅果蝇及其野生寄主果实和寄生蜂的发生情况。使用诱捕器监测斑翅果蝇成虫，每周在四个不同地点（瓦房店、法库、凤城和沈阳）采集疑似果实。结果表明，斑翅果蝇分布于辽宁甜软皮水果产区，树莓是受害最严重的水果。在田间调查中，发现来自非作物生境的四种野生浆果受到斑翅果蝇侵害，并采集到两种寄生蜂（[寄生蜂名称1]和[寄生蜂名称2]）。在整个调查期间（6月至10月），不同调查地点的斑翅果蝇成虫种群动态相似；成虫数量在8月增加并达到峰值，然后下降，直到10月不再检测到果蝇。
