摘要
为了分析影响螺旋粉虱迁移的原因,在已知的螺旋粉虱的生物学特性及部分活动规律的基础上,利用人工气候箱等设施对温度及光照变化对螺旋粉虱起飞活动的影响进行了研究。结果表明:螺旋粉虱从15℃开始起飞,起飞的数量随着温度的升高而增加,最适起飞温度为30℃;从黑暗到给光的处理比从给光到黑暗的处理更能引起螺旋粉虱起飞数量的增加;雄虫在光照有变化的条件下会产生求偶反应;起飞成虫的性比大于1。
To analysis the reasons why spiraling whitefly move, based on the known biological characteristics and partial activity patterns, artificial climate chamber and some other equipments were used to study the effects of temperature and light change that the flying number began on take-off activity of spiraling whitefly Aleurodicus dispers to increase since 15 ℃, the optimum taking off temperature es. The results showed was 30 ℃. From darkness to light, more whiteflies took off. With the change of light, male whiteflies made courtship response. The sex ratio of Aleurodicus disperses taking off was above 1.
