试验就不同颜色、不同放置时间色板对胡麻地害虫及天敌的诱集效果进行研究。结果表明:不同颜色色板对昆虫的诱集效果不同,其中白板和黄板对蚜虫诱集效果显著,黄板、蓝板和淡蓝板对蓟马诱集效果显著,黄板、蓝板、绿板对潜叶蝇诱集效果显著。色板诱集昆虫益害比为1∶186和1∶467。蚜虫(有翅蚜)和蓟马类多在白天6∶00~18∶00活动,潜叶蝇24h内活跃性没有明显时间差别。
Experiments on different colors, different time to put the swatches flax pests and natural enemies of the trapping effect. The results showed that different color swatches had different trapping effects on insects, in which white and yellow plates had a significant effect on aphid trapping, and yellow, blue and pale blue plates had significant effect on the collection of thrips, Green leaf on leaf miner trap effect is remarkable. Swatches trap insect benefit ratio of 1:186 and 1:467. Aphids (winged aphids) and thrips mostly in the day 6:00 ~ 18:00 activity, leaf miner 24h activity was no significant difference in time.
