BACKGROUND
The ladybird beetle (Mulsant) is an important natural enemy of tetranychid mites and functions as a biological control of these plant pests. The development, survival and reproduction of were studied when fed on three artificial diets. The components of the artificial diet that could be reared successfully on for one generation with no use of tetranychid mites were examined.
METHODS
Artificial diets consisted of sucrose, honey, royal jelly, agar, yeast, date palm pollen supplemented in different diets with hen's egg yolk (AD1, as basic diet), Zeller eggs (AD2), or . eggs and 2,4-dihydroxybenzoic acid (AD3).
RESULTS
Adults and larvae of fed on AD1 had a shorter immature development and preoviposition periods than those fed on AD2 and AD3. The total number of deposited eggs was significantly higher for the females fed on AD3 than on the other diets. The intrinsic rate of increase () of was highest on AD3, followed by AD2, and AD1.
CONCLUSION
performed best on AD3, indicating the potential of this artificial diet for the mass rearing of this important predatory ladybird beetle.
背景
瓢虫（穆尔桑特）是叶螨的重要天敌，对这些植物害虫起到生物防治作用。研究了以三种人工饲料喂养时瓢虫的发育、存活和繁殖情况。研究了在不使用叶螨的情况下，瓢虫能够成功饲养一代的人工饲料成分。
方法
人工饲料由蔗糖、蜂蜜、蜂王浆、琼脂、酵母、枣椰花粉组成，在不同饲料中添加蛋黄（AD1，作为基础饲料）、泽勒卵（AD2）或……卵和2,4-二羟基苯甲酸（AD3）。
结果
以AD1喂养的瓢虫成虫和幼虫的未成熟发育和产卵前期比以AD2和AD3喂养的要短。以AD3喂养的雌性瓢虫产卵总数明显高于其他饲料喂养的。瓢虫在AD3上的内禀增长率最高，其次是AD2和AD1。
结论
瓢虫在AD3上表现最佳，表明这种人工饲料在大规模饲养这种重要捕食性瓢虫方面具有潜力。
