| 摘 要： | 通过1992～2004年13年的观测结果表明,危害成都地区草坪的粘虫为外迁入的二代粘虫,其暴食期一般年份发生在7月中旬,最佳防治时期在7月上旬;诱蛾量和草把诱卵量与粘虫的发生程度密切相关,可作为草坪粘虫发生的测报因子,且方法简便、有效。

| Abstract: | An observation made from 1992 to 2004 on lawn Mythimna separata in Chengdu region shows that these Mythimna separata are the offspring of the Mythimna separata immigrated.Their soaring appetite comes out in the midge July.Therefore, the best controlling time is the first ten-day period of July.There is a close relationship between occurrence frequency of Mythimna separata and moth trapping as well as stalk-bundle larvae trapping, and can be taken as an observation and evaluation factor which is simple and effective. |
