Three artificial diets were developed and tested for their suitability for immature development and survival of the ladybird Propylea japonica (Thunberg) (Coleoptera: Coccinellidae). The artificial diet based on the oriental armyworm, Mythimna separata (Walker) (Lepidoptera: Noctuidae), resulted in 66.5% survival and was a potential food for mass rearing of P. japonica. The effect of this alternative diet was assessed independently for larval development and adult reproduction by adding various numbers of frozen aphids, and finally an artificial rearing scheme was established that could save about 80% of natural food (aphids). The results showed that the survival rate and fecundity of P. japonica reared on the best artificial diet or aphids alone were similar. A rearing scheme using mainly M. separata‐based artificial diet and a small number of frozen aphids for the mass production of P. japonica became possible.

在含有东方粘虫Mythimna separata的饮食上人工饲养瓢虫Propylea japonica

研发了三种人工饮食，并测试了它们对瓢虫Propylea japonica（Thunberg）（鞘翅目：球虫科）的不成熟发育和存活的适合性。以东方粘虫Mythimna separata（Walker）（鳞翅目：夜蛾科）为基础的人工饮食，可以使66.5％的存活率成为潜在的日本粳稻大规模繁殖的食物。通过添加各种数量的冷冻蚜虫，分别评估了这种替代饮食对幼虫发育和成年繁殖的影响，最终建立了一种人工饲养方案，可以节省约80％的天然食物（蚜虫）。结果表明，粳稻的成活率和繁殖力强。最佳人工饮食或仅蚜虫饲养的情况相似。可以使用主要基于分离的分枝杆菌的人工饮食和少量的冷冻蚜虫来大规模生产粳稻的饲养方案。
