野蛞蝓土名叫赤膊蜓蚰螺,是一种杂食性害虫,寄主作物种类多,分布面广,在台州市为害已有30余年的历史。由于没有搞清它的活动规律和缺乏有效的防治药物,致使发生面积逐年扩大,为害年趋严重。为此,近年来我们在这两个方面作了一些探索研究,取得如下初步结果。1.野蛞蝓出土活动规律根据2年定田、定期、不定点分层挖土(每隔10天挖土1次,深30厘米,每点挖土50～100平方厘米)的调查结果看,以4、5月份,10厘米以上土层查到
It is a omnivorous pest, with many kinds of host crops and a wide distribution. It has been damaged in Taizhou for more than 30 years. Due to the lack of understanding of the rules of its activities and the lack of effective prevention and treatment medicines, the area of occurrence has been expanding year by year and the annual damage becomes even more serious. To this end, in recent years we have done some exploratory research in these two aspects and achieved the following preliminary results. 1. Wild 蛞 蝓 unearthed the law of activity According to the survey results of two years of fixed-field, regular, irregular layered digging (dig every 10 days, 30 cm deep, each dig 50 to 100 square centimeters) In April and May, 10 cm above the soil found
