摘要
田间药效试验表明,化学防治要掌握“主攻蛹期,成虫期扫残”的防治策略。用40 %甲基异柳磷乳油3.75 kg/hm2拌毒土于蛹期,撒施于土内,防治效果为84.48 %。成虫期防治,用10 %一遍净可湿粉剂2000倍、10 %大功臣可湿粉剂2 000倍或80 %敌敌畏乳油1 000倍喷雾,或80 %敌敌畏乳油2.25～3.75 kg/hm2拌麦糠熏杀,防治效果达95 %～100 %。
The tactics of chemical control should be pupa-stage control and adult-stage control on wheat midge as remedial measure. The field experiments show that application of 40 % Isofenphos-methyl EC 3.75 kg/hm2 mixed with fine soil has effectiveness of 84.48 % during pupal stage. Applications of 10 % Imidacloprid WP 2 000 times for spraying or 80 % DDVP EC 2.25～3.75 kg/hm2 mixed with wheat husk during adult stage have effectiveness of 95 %～100 %.
