甘薯盲蝽在我国台湾省经常大发生成灾,福建、四川对此虫曾有记载,其他省区没有此虫为害的报道。近年来,甘薯盲蝽在我区有虫口激剧上升的趋势,并且除为害甘薯、花生等作物外,还在秋大豆上发生。大批成虫从花生、甘薯地迁入秋大豆上产卵,造成初出苗的大豆子叶发白枯黄。据我们在8月16日调查,甘薯上每平方尺有成、若虫107头,花生地每平方尺有35头,大豆地每平方尺平均有成虫9头,高的达54头。

In recent years, sweet potato Lygus bug in my area has a sharp rise in the trend of insects, and in addition to damaging sweet potato, peanut and other crops, but also in the autumn soybean occurred. A large number of adults from peanut, sweet potato moved into the autumn soya bean spawning, resulting in the emergence of early emergence of soybean cotyledons white yellow.
