摘　　要：通过USB-显微镜实地观察记录桑木虱的生物学特征、发生特点,指出桑木虱的发生与园林绿化上柏树的引种增多等原因有关。化学防治可在卵期、若虫期喷洒25%喹硫磷乳油、35%螺虫·噻嗪酮悬浮剂、25%吡丙·噻嗪酮悬浮剂等兼有杀卵作用的药剂,在5月份后可使用50%辛硫磷乳油、40%毒死蜱乳油、50%啶虫咪水分散粒剂、40%啶虫.毒乳油等药剂防治。The biological characteristics and occurrence characteristics of Psylla were observed and recorded by usb-microscope.It was pointed out that Psylla was related to the increase of the introduction of cypress trees on the landscape.Chemical control could spray 25%quinalphos emulsifiable concentrate,35%Spirotetramat-thiazinone suspension,25%Pyriproxyfen·thiazinone suspension and other agents with egg killing effects in egg stage and nymph stage,After May,50%phoxim emulsifiable concentrate,40%chlorpyrifos emulsifiable concentrate,50%acetamiprid water dispersible granule,40%acetamiprid-chlorpyrifos emulsifiable concentrate can be used for control.
