摘要
榆紫叶甲（ＡｍｂｒｏｓｔｏｍａｑｕａｄｒｉｉｍｐｒｅｓｓｕｍＭｏｔｓｃｈ．）是我国榆树的毁灭性害虫。该虫分布广，密度大，食性单一，常年成灾，给防治带来困难。为了避免常规杀虫剂造成的。１年控制、２年发生、３年成灾”的被动局面，利用昆虫生长调节剂灭幼脲Ⅲ号胶悬剂及油剂和氟幼灵（ｔｒｉｆｌｕｍｒｏｎ）胶悬剂及油剂进行防治。可同时杀死幼虫、成虫和卵。灭幼脲Ⅲ号油剂和氟幼灵油剂可杀卵８５％～９０％左右。两种药剂的胶悬剂和油剂均可杀死幼虫９５％～１００％、杀死成虫５０％左右。该类药剂处理后未马上死亡的成虫、产卵量下降８４％～９０％，卵的孵化率降为１０．６４％～１９．５７％。该类药剂具有安全、高效、经济的特点，又能保护天敌、增强了森林自控能力、从而有效地控制了榆紫叶甲的种群。
Ambrostoma quadriimpressum Motch.is a ruinous pest of elm in China.Its extensive distribution. high density.single feeding habits.and serious happening all the year round bring about great difficult to the control.In order to get rid of this malpractice of' Control in the first year,take place in the second year and cause disaster in the third year'.we used the regular of pest growth such as benzoylphenol urea No.3 and triflumuron to control the pest.The oil miscible liquid of these two insecticides can kill eggs about 85%￣90%.kill adults 50% or So.Their oil miscible liquid and flowable formulation can kill larva 95%￣100%.The amount of eggs oviposited by the survived adults decreased about 84%￣90%.The hatching rate of these eggs dropped to 10.64%￣19.57%.The results show that benzoylphenol urea No.3 and triflumuron have characters of safe.high efficiency and economy.They can protect the natural enemies,strenghten the self-control ability of the forests.Thereby can regulate the population of Ambrostoma quadriimpressum effectively.
