黄板不同悬挂高度和不同颜色对柑橘粉虱的诱杀效果

Effects of Different Hanging Heights and Colours of the Yellow Board on the Trapping of Dialeurodes Citri

为探索柑橘粉虱的绿色防治方法,进行黄板诱杀柑橘粉虱试验,研究黄板不同悬挂高度和不同颜色对柑橘粉虱的诱杀效果。结果表明:黄板不同悬挂高度的单板日均诱虫量由高到低依次为悬挂在冠层下50 cm、冠层下20 cm、与冠层水平,悬挂在冠层下50 cm诱集效果最好,其单板日均诱虫量为28.3头,高于冠层下20 cm,显著高于与冠层水平的诱集量;黄板不同颜色的单板日均诱虫量由高到低依次为黄色、橘黄色、浅黄色,黄色黄板的诱集效果最好,其单板日均诱虫量为29.65头,略高于橘黄色黄板,显著高于浅黄色黄板。

In order to explore the green control method of Dialeurodes citri, the experiment of trapping Dialeurodes citri with yellow board was carried out to study the effects of different hanging heights and colours of the yellow boards. The results showed that the average daily trapping amount of Dialeurodes citri from high to low was 50 cm below the canopy, 20 cm below the canopy and canopy level. The trapping effect of 50 cm below the canopy was the best, its average daily trapping amount was 28.3, which higher than the amount of 20 cm below the canopy, and significantly higher than the canopy level. The daily average trapping amount of yellow board with different colours from high to low was yellow, orange and light yellow. The trapping effect of yellow board was the best, its daily average trapping amount was 29.65, slightly higher than orange yellow one and significantly higher than light yellow one.
