    摘要:

    对黄瓜大田内黄板诱杀烟粉虱成虫的最佳方法及对烟粉虱种群数量的控制作用进行了研究,结果表明:烟粉虱对黄板具有强烈的正趋性。对寄主黄瓜上的烟粉虱成虫进行黄板诱杀时,最好是将黄板垂直悬挂于黄瓜行间,黄板高度基本上保持与植株顶端相平。黄板对黄瓜田其他昆虫如有翅瓜蚜、瓜蓟马、弹跳虫、蚊、斑潜蝇等也有显著的诱杀作用。烟粉虱种群趋势指数,黄板诱杀区为3.5198,对照区为8.6300;黄板诱杀干扰作用控制指数达到0.4079,与对照区相比,黄板诱杀对烟粉虱种群的控制效果可以达到59.21%;黄板诱杀区天敌的排除作用控制指数为6.7917,对照区为6.1617。

    Abstract:

    The best method to trap Bemisia tabaci adults using yellow card and the control effect of yellow card's (trap on) the B. tabaci population in the cucumber field were studied, the results showed that B. tabaci has strong taxis to the yellow card. When the yellow card to trap the adults of Bemisia tabaci was used on cucumber, the best method is to hang the yellow card vertically between the rows of the cucumber plants, and the height of yellow card is almost kept the same as the top of the cucumber plant. The yellow card can also trap other insects in the cucumber field such as springtails, cucumber aphids, cucumber thrips, etc. Life tables constructed by the affecting factors in the control area and yellow card-used area have been established. In control area, the B. tabaci population trend index (I-value) is 8.63, while in the yellow card-used area, its I-value is only 3.519 8; The interference index of population control (IIPC) of yellow card's trap and kill reaches 0.407 9. The exclusive index of population control (EIPC) in yellow card-used area is 6.791 7, while in the control area, the EIPC is 6.161 7.
