甘蓝夜蛾(Mamestra brassieae Linnaeus)在我区分布广、发生量大,严重危害豌豆、十字花科蔬菜等,常年需要防治,是我区主要害虫之一。王富顺(1978)就其生物学特性和防治方法进行了研究,曾筛选出几种有效的化学药剂。但其中多为目前禁止生产使用的有机氯农药。我区目前还没有明确对甘蓝夜蛾有很好防效的农药品种,。针对此问题,笔者于1085年在堆龙德庆县以新型杀虫剂8408和9％D.D.Vp粉剂80％D.D.Wp乳油、40％乐果乳油、3％呋喃丹颗粒剂为材料,对甘蓝夜蛾进行了防效试验。
Mamestra brassieae Linnaeus is one of the main pests in our region. It is widely distributed in my area, causing serious pests and perennial cruciferous vegetables. Wang Fushun (1978) on its biological characteristics and prevention methods were studied, had screened several effective chemical agents. However, most of them are organochlorine pesticides that are currently banned from production. At present, there is no clear pesticide variety that has a good control effect on cabbage budworm. In response to this problem, the author in 1085 in Longdeqing County pile with a new insecticide 8408 and 9% DDVp powder 80% DDWp EC, 40% dimethoate, 3% carbofuran granules for cabbage budworm Control effect test.
