正交试验法研究黄板对3种温室西葫芦害虫的诱杀作用

应用正交试验法研究了黄板悬挂高度、黄板形状、黄板距温室出口距离、黄板距北墙距离4个因素对黄板诱杀3种温室西葫芦害虫的影响。结果表明:4个因素对诱杀温室白粉虱都具有显著、极显著影响,黄板悬挂高度和黄板距出口距离对诱杀美洲斑潜蝇有显著影响;黄板距北墙距离对诱杀有翅瓜蚜具有极显著影响。黄板诱杀害虫的4因素组合为黄板高出植株0.2 m、平板形、距出口91 m、距北墙距离0.7 m时诱杀虫量最大。

Studies on the insecticidal effects of yellow sticky traps on three pest insects on greenhouse pumpkins by orthogonal matrix method

Four factors,yellow sticky trap's height,shape,distance to greenhouse exit and distance to the north wall,that affect the insecticidal effects of yellow sticky trap(YST) on three pest insects on greenhouse pumpkins were studied by orthogonal matrix method.The results showed that the distance between YST and the north wall significantly affected the number of cotton aphids trapped.The height and the distance between YST and greenhouse exit had significant effects on the number of American leaf maggot trapped.And these four factors had very significant effects on the number of greenhouse whiteflies trapped.Most insects were trapped when YST was 0.2 m above plants,flat-shaped,91 m to greenhouse exit and 0.7 m to the north wall.
