摘要
分为 3部分 :第 1部分为光因子对棉铃虫雌蛾求偶行为的影响 ;第 2部分为光因子对棉铃虫雌蛾性信息素 ( Z-1 1 -1 6:Ald)含量的影响 ;第 3部分为光因子对棉铃虫雌蛾脑因子活性的影响。研究结果表明 :用非正常光周期、间隔光照、不同光质处理棉铃虫雌蛾后 ,求偶峰值下降 ,求偶节律混乱 ,性信息素含量下降 ,脑因子活性受到抑制。主要研究目的是探讨一种不使用或少使用农药的新型生态防治方法。
The effects of light factors on the calling behavior, sex pheromone titer and the activity of brain suboesophageal ganglia(Br SOG) of female cotton bollworm, Helicoverpa aramigera , were investigated. Unusual photoperiod, exposure to light during scotophase and red, orange, yellow, green, blue, black, violet and white color light were used to treat female cotton bollworms. The results showed that on these factors, the calling peak value decreased, calling rhythm was disrupted, sex pheromone titer decreased, the activity of Br SOG was inhibition. These results are useful to explore a new ecological approach for controlling insect pests not relying on or little relying on pesticides.
