摘要
烟粉虱是世界性重要害虫之一,严重影响温室蔬菜和花卉以及大田作物的产量。利用自制的LED-塑料杯诱杀器研究烟粉虱的趋光规律。研究结果表明,烟粉虱对三种灯的趋性差异极显著,烟粉虱对甲、乙两种灯趋性较大;三种距离之间差异极显著,15 cm和60 cm对粉虱有很好的诱集效果;黏杀剂之间差异极显著,且黏杀剂1比2的效果好。LED-塑料杯对烟粉虱的诱捕作用最大可达44.4%。
Bemisia tabaci, which is one of the important pests all over the world, seriously infects vegetables and flowers in greenhouses and crops yield in fields. LED-plastic trap made using tropism characteristic of B. tabaci was studied. It is indicated that the tropism of B. tabaci was significant difference among three lamps, and the tropism to lamp first and second were better than lamp third; significant difference was found among three distances, and the effect of trap was very good at 15 cm or 60 cm; it was also significant difference between two tanglefoots, the effect of the tan- glefoot No. 1 to whitefly was better than No. 2. The maximal effect of LED-plastic trap to B. tabaci was 44. 4%.
