摘要
在贵阳市乌当奶牛场大面积人工草地上，对通过适时合理刈割控制粘虫危害进行了研究。结果表明，在５～７月适时重刈，可使粘虫的第２代卵、初孵幼虫随牧草带出草地，降低虫口密度，减轻其危害。由此认为，适时刈割对大面积人工草地控制粘虫的发生和危害是行之有效的。
Appropriate cutting to control the damage of Leucania separata on established pasture was studied at Guiyang City Wudang Dairy Farm. The results indicated that, extensive cut during May to July could bring out eggs and larva of 2nd generation with forage cut thus reduce their density and damage. This concept could also be adopted on the control of occurence and damage of Leucania separate in big areas.
