不同物理措施对娃娃菜小菜蛾的诱杀效果

为给武威市高原夏菜小菜蛾的监测及绿色防控提供科学依据,选择光诱、色诱、性诱及不同组合等多种物理诱杀措施,设计16个处理,对娃娃菜田小菜蛾诱杀效果进行比较研究。结果表明,在小菜蛾成虫发生期,使用紫光灯+诱芯组合诱杀措施效果最好,单板日均诱蛾量达到224.9头,为单独使用紫光灯诱杀效果的1.6倍。小菜蛾发生期推荐使用紫光灯配合性信息素诱芯进行防治,春季小菜蛾发生较轻时可单独使用紫光灯或性信息素诱芯进行防治。

Effect of Different Physical Measures on Trapping and Killing Effect against Cabbage Moth in Baby Cabbage

To provide references for the monitoring and green prevention and control of cabbage moth(Plutella xylostella)in the plateau summer vegetable production in Wuwei, 16 treatments including light trap, color induction, sexual induction and their combinations were tested to compare their trap and killing effects against cabbage moth in baby cabbage fields. Results showed that during the adult occurrence period, purple light lamp plus lure core showed the best trap and killing effect, moth individual number daily trapped per plate was 224.9 which was 1.6 times higher compared with that of the perplex light lamp only. Therefore, during the adult occurrence period of cabbage moth, it was recommended to use purple light plus sex pheromone lure coreas the measure for prevention and control whereas purple light or sex pheromone lure coreonly was recommended for spring control with less occurrence.
