摘　　要：紫薇绒蚧以若虫和雌成虫危害为主,且分泌蜡丝包裹身体固定危害。为寻求高效、低毒、无污染的农药进行科学防治,利用废机油与洗衣粉1∶1混合均匀的水乳剂进行喷药试验。结果表明,以机油水乳剂浓度6%、9%防治的虫口减退率为99.5%、100%,防效为92.0%、92.5%,达到高效、绿色防治的目的。The damage of Eriococcus Lagerstroemiae Kuwana is mainly caused by nymphs and female adults,and they secrete wax silk to encase the body. In order to achieve high efficiency,low toxicity and pollutionfree pesticide control,the experiment of spraying waste motor oil and washing powder with 1 ∶1 mixture of water solvent was carried out. The results showed that the decline rate of insect population was 99.5% and 100% when the concentration of organic oil-water emulsion was 6% and 9%, the control effects were 92.0%and 92.5%, which achieved the purpose of high efficiency and green control.
