粘虫板对葱地种蝇成虫的诱杀效果

为探明黄色、深蓝色、浅蓝色和银灰色4种颜色粘虫板对葱地种蝇成虫的诱集效果,于大蒜田葱地种蝇成虫发生期,在田间摆放上述不同颜色的粘虫板,每日检查粘虫板诱集成虫的数量,比较不同颜色、不同摆放方式和喷布诱集物质粘虫板的诱杀效果.结果表明,4种颜色粘虫板对成虫的诱集效果以深蓝色最好,浅蓝色次之,黄色和银灰色效果差.粘虫板在大蒜行间高立放和低立放的诱杀效果均好,且差异不显著,而平放的单面诱集效果优于立放的单面诱集效果.在蓝色粘虫板上喷布10％蜂蜜水能显著增加对葱地种蝇成虫的诱集效果.

Trapping efficiency of sticky insect boards against Delia antiqua in the fields

During the occurring stage of Delia antique(Meigen) adults,field comparative experiments were conducted to detect trapping efficiency of yellow,dark blue,light blue and silver gray sticky insect boards,different placements and different honey concentrations sprayed on the surfaces of these boards.Trapping efficiency of sticky insect boards was investigated in the fields by checking the numbers of D.antiqua on the boards every day.The results showed that the trapping efficiency of dark blue sticky insect boards was the best among the boards of four different colors,and the light blue sticky insect boards were a bit better than the yellow and silver gray ones.The trapping efficiency of two different placements(higher-vertical and lower-vertical placement) were both high without significant differences,and the single-side trapping efficiency of horizontal placements on the ground was better than the vertical ones(single-side).The boards with 10% honey solution sprayed on the surface could significantly improve the trapping efficiency.
