棉铃虫的抗药性不断增强 ,单纯的化学防治已难以控制棉铃虫的暴发成害 ,加之目前市场上高效杀虫、杀卵剂不多 ,如何有效地控制棉铃虫危害 ,已成当务之急。采取综合防治的手段在 7月成虫羽化盛期 ,用黑光灯诱杀成蛾 ,可减少田间落卵量80 %以上 ,整个棉铃虫发生期间 ,黑光灯控制区域较非灯控区域减少药物防治 8～ 10次 ,单位面积节约农药成本 6 0 0～ 75 0元 /hm2 ,减少投工成本 75 0～ 90 0元 /hm2 ,共计节约成本 15 0 0元 /hm2 。无为县河坝镇的成功经验证明 ,采用改进组装型黑光灯在田间大面积诱杀棉铃虫成虫是一种控制棉铃虫危害行之有效的好方法
The resistance of cotton bollworm has been continuously enhanced. Simple chemical control has made it hard to control the outbreak of bollworm. In addition, there are not many effective pesticides and egg-killing agents on the market. How to effectively control the harm of bollworm has become a top priority. Taking the means of comprehensive prevention and control during the emergence period of adults in July and the trapping and killing of moths with black light, the number of eggs shed in the field can be reduced by more than 80%. During the occurrence of the whole cotton bollworm, 10 times, the unit area saves pesticide cost 6 0 0 ~ 75 0 yuan / hm2, reduce the operating cost of 75 0 ~ 90 0 yuan / hm2, total cost savings 15 0 0 yuan / hm2. The successful experience of Heba County in Wuwei County proves that it is a good way to control adults of Helicoverpa armigera
