枇杷瘤蛾的生物学特性及其防治研究

Bionomics and control of selepa celtis moore

枇杷瘤蛾是枇杷的首要害虫。研究在不同恒温条件下枇杷瘤蛾生物学特性，结果表明福建莆田地区枇杷瘤蛾1年发生约5代，3～4代为主要危害代、与枇杷夏、秋梢的萌发期相一致。用1％阿维菌素乳、20％杀灭菊酯乳油、90％敌百虫结晶、25％灭幼脲3号悬浮剂药剂不同浓度处理对枇杷瘤蛾室内药效试验表明，阿维菌素、灭幼脲与敌百虫、杀灭菊酯的防效存在显著差异，阿维菌素、灭幼脲致死时间比敌百虫、杀灭菊酯长。

Selepa celtis is the main pest attacking longan. The bionomics of selepa celtis on longan was observed at different constant temperature. The pest was found to have 5 generations annually in Putian, Fujian province and mainly in the third and fourth generations which caused damage accordant with summer and autumn shoots sprouting periods. Control effect of selepa celtis was significantly different among 1% avermectin, 25% benzoylphenal urea Ⅲ , 90% dipterex and 20% fenalerate under laboratory conditions. The lethal time of avermectin and benzoylphenal urea Ⅲ was longer than dipterex and fenalerate.
