蚧壳虫是一类难于防治的害虫,种类多、发生范围广,严重影响果树生产。蚧壳虫防治的难点在于若虫时期短,防治时期极易错过,而成虫雌蚧体外被有蜡质介壳,化学药剂不易穿透导致药效极低。为了提高化学药剂防治蚧壳虫的效果,进行了化学药剂筛选、展着剂筛选以及化学药剂与展着剂混合使用的筛选试验。结果表明：毒死蜱1 000倍液与展着剂甲基三氧乙基硅烷2 000倍液混合使用,对桑白蚧成虫防治效果最好,相对防效达81.21%。
개각충시일류난우방치적해충,충류다、발생범위엄,엄중영향과수생산。개각충방치적난점재우약충시기단,방치시기겁역착과,이성충자개체외피유사질개각,화학약제불역천투도치약효겁저。위료제고화학약제방치개각충적효과,진행료화학약제사선、전착제사선이급화학약제여전착제혼합사용적사선시험。결과표명：독사비1 000배액여전착제갑기삼양을기규완2 000배액혼합사용,대상백개성충방치효과최호,상대방효체81.21%。
The scale insect is a kind of important pests that is difficult to be controlled,which has more kinds,wide occurrence range,and serious damage to fruit production.The difficulty in the prevention and control is the shorter period of nymph.The female adult has waxy shell,so the chemicals are difficult to penetrate it and the effect is much lower.To improve the control effect of chemicals,the chemicals and extenders are selected and mixed.The results show that the mixed use of 1 000 times liquid chlorpyrifos and 2 000 times liquid of triethoxymethyl-silane can improve the control effect,the control effect on the adult of Pseudaulacaspis pentagona is 81.21%.
