通过比较3种测报工具(诱蛾器、虫情测报灯、高空探照灯)对吉林省粘虫成虫的诱捕效果,结合卵巢解剖技术确定粘虫虫源类型,探讨适用于吉林省各虫源类型粘虫的监测工具。结果表明,吉林省的粘虫成虫可分为3种虫源类型：迁入型、混合型、迁出型。3种测报工具均能有效监测粘虫成虫发生的相对高峰期。以诱集数量为标准的话,针对迁入型虫源,选择诱蛾器、高空探照灯为测报工具；针对混合型虫源,虫情测报灯诱捕效果较好；针对迁出型虫源,应选择虫情测报灯、诱蛾器为适宜的测报工具。
英文摘要:
The attracting effects on Mythimna separate (Walker) among trap catches, pest forecast light trap and high-altitude searchlight were investigated in Jilin province. Based on ovarian dissection level, this study was conducted to investigate the suitable method for different population characteristics. The results showed that the adult of M. separate could divide into three population characteristics as immigration, mixture and emigration. The monitoring tools could monitor occurrence effectively. Based on the trapping numbers, trap catches and high-altitude searchlight could be effective to the immigration, pest forecast light trap had the best trapping efficacy to the mixture, pest forecast light trap and trap catches could be monitoring tools to emigration.
