摘要
杨小舟蛾是一种为害杨树叶部的主要害虫,为有效控制杨小舟蛾存活密度,降低虫口基数,进行了野外林地及室内土壤湿度对杨小舟蛾蛹羽化及存活的影响研究。结果表明:土壤湿度对杨小舟蛾蛹羽化和存活有显著影响。土壤湿度越大,杨小舟蛾蛹羽化和存活率越低,相反,土壤湿度越小,杨小舟蛾蛹羽化和存活率越高。
Micrornelalopha tyoglodyta（Groestr） is one of the main pests on poplar leaf.The effect of soil moisture in the open forest land and the room to Micrornelalopha tyoglodyta（Groestr） emergence and survival were researched to control Micrornelalopha tyoglodyta（Groestr） survival density and reduce the insect mouth cardinal number.The result indicated that the soil moisture had remarkable influence to Micrornelalopha tyoglodyta（Groestr） emergence and survival,the bigger soil moisture was,the lower Micrornelalopha tyoglodyta（Groestr） emergence and survival percentage were.On the contrary,the smaller soil moisture was,the higher Micrornelalopha tyoglodyta（Groestr） emergence and survival percentage were.
