摘要
为辣椒斜纹夜蛾的防控提供依据,采用昆虫性信息素电子测报系统监测与性信息素诱芯田间诱捕相结合,研究贵阳市、合肥市和毕节市辣椒斜纹夜蛾的发生规律。结果表明:斜纹夜蛾发生高峰期贵阳市分别在5月中旬、7月上旬和8月上旬,合肥市分别在5月中旬、6月下旬和7月下旬,毕节市分别在5月下旬、7月下旬和8月下旬。试验区全年斜纹夜蛾诱捕量合肥市最多,为3276头/台;贵阳市其次,为2801头/台;毕节市最少,为1758头/台。在合肥市采用单一性诱剂防控斜纹夜蛾效果较差,但性诱剂+药剂防控斜纹夜蛾效果较好,且能减少施药次数。
The occurrence regularity of Prodenia litura in pepper field was studied by using the insect sex pheromone electronic measurement and forecast system and field traps with sex pheromone lure in Guiyang,Zunyi and Bijie to provide the scientific basis for prevention and control of P.litura in pepper field.Result:The peak period of P.litura occurrence in Guiyang,Zunyi and Bijie is in the middle ten days of May and the first ten days of July and August,in the middle ten days of May and the last ten days of June and July and in the last ten days of May and the last ten days of July and August respectively.The annual trap quantity of P.litura in Zunyi,Guiyang and Bijie is 3276/trap,2801/trap and 1758/trap separately.The single sex pheromone pattern has the poorer effect for prevention and control of P.litura but the sex pheromone+pesticides pattern with less pesticide applying time has the better effect for prevention and control of P.litura in Zunyi.
