不同颜色防虫板防治北方茶园黑刺粉虱效果研究

摘要

研究了不同颜色防虫板对北方茶园黑刺粉虱的防治效果。结果表明，各种颜色防虫板对黑刺粉虱均有一定的防治效果，其田间防效大小顺序依次为：黄板＞绿板＞蓝板；其累积诱虫效果大小顺序依次为：黄板绿板蓝板。黄板田间防治效果和粘虫效果最好，田间防效最高达88.3%，粘虫效果为123.6头/（m2·d），最适宜北方茶园黑刺粉虱的防治。%Control effect of different color sticky traps on spiny black whitefly (Aleurocanthus spiniferus Quaintance) was studied.The results showed that all kinds of colors sticky traps had certain control effect on spiny black whitefly, field efficacy decreased in this order:yel-low sticky trap > green sticky trap >blue sticky trap;cumulative insect -at-tracting effect decreased in this order:yellow sticky trap > green sticky trap >blue sticky trap. Yellow sticky trap had the best control effect, and the highest control effect could reach to 88.3%, in-sect-attracting effect could reach to 123.6 head/(m2·d),so the yellow sticky trap was the most appropriate sticky trap to control spiny black whitefly in north-ern tea plants growing area.
