研究了上海地区柑橘红蜡蚧的发生规律，结果表明：该虫一年发生1代，以受精雌成虫越冬，卵5月底开始孵化，6月初达到孵化高峰，孵化期长达40 d 左右，雌成虫有效卵孵化量可达500—800粒？头。在室外喷雾100倍95％矿物油 EC、4000倍240 g？L 螺虫乙酯 SC、1000倍40％杀扑磷 EC、1000倍1．2％苦参碱·烟碱EC，7 d 后防效均达到80％以上。建议防治红蜡蚧时交替使用上述4种农药，可有效避免害虫产生抗药性问题。

The occurrence of Ceroplastes rubens Maskell was investigated in Shanghai.The results showed that the insect occurred for one generation annually and overwintered as fertilized female adults.The incubation of fertilized eggs could last more than 40 days,the hatching peak of which was from late May to early June,each fe-male adult could yield 500—800 eggs.The field tests showed that the corrected mortalities of the larvae were all above 80% at 7 days after spraying respectively with 100-fold dilution of 95% petroleum oil EC,4 000-fold dilu-tion of 240 g?L spirotetramat SC,1 000-fold dilution of 40% methidathion EC,1 000-fold dilution of 1.2% ma-trine·nicotine EC.It was suggested that alternate use of four pesticides above might delay the onset of resist-ance.
