二种捕食性瓢虫人工饲养繁殖技术的研究

1990年用日本龟蜡蚧和人工代饲料饲养矢尖蚧的天敌优势种湖北红点唇瓢虫与二双斑唇瓢虫,结果表明:用日本龟蜡蚧饲养湖北红点唇瓢虫,其产卵量比二双斑唇瓢虫高3倍以上;而用人工代饲料饲养,两种瓢虫的产卵量极低。人工繁殖的湖北红点唇瓢虫能在施秉县农业局柑桔园正常发育,顺利越冬,现已对此园的矢尖蚧起到了明显的防治效果。

Studies on the rearing techniques of two predacious lady beetles

This paper deals with the rearing of two lady beetles. Chilocorus hupehanus Miatake and Chilocorus bijugus Mulsant. By using Ceroplastes japonicus Green and artifical diet, the experimental data indicated that the egg number of the former is about three times as many as the later, but when the artifical diet is used, the numbens of both two kinds are very low. Breleasing two lady beetles in the citrus orchard in Shingbing Counity, Chilocorus hupehaus Miatake has established stable population and made obvious control effect, but Chilocorus bijugus Mulsant hasn't jet.
