野蛞蝓在贵阳蔬菜地区一年发生三代,主要以二、三代成、幼体越冬。以春、夏季发生量大,危害重;秋、冬季发生量较小,危害较轻。全年田间数量消长有三个明显的高峰,即5月下旬至6月上旬、7月下旬至8月上旬和10月上旬,以第一次高峰的田间数量大。采取压低越冬虫源基数,恶化各虫态的生存环境,抓住第一次高峰期用药防治,酌情用药防治第二、三次高峰,能收到较好的防治效果。
Wild 蛞 蝓 in Guiyang vegetable area occurs three generations a year, mainly in two or three generations, juvenile wintering. Occurred in spring and summer, large-scale, endangering heavy; autumn and winter occur in smaller amounts, less harmful. There are three distinct peaks in the decline of the number of field crops throughout the year, that is, from late May to early June, from late July to early August and early October, with a large number of fields at the first peak. To take down the base of overwintering insect pests, worsen the living conditions of the various insect states, to seize the first peak drug prevention and treatment, as appropriate, the second and third peak drug control, can receive better control effect.
