【摘要】 用米蛾成虫、米蛾卵、人工卵、米蛾卵加人工卵作饲料,饲养仓虫天敌黄色花蝽均能完成发育和产卵。不同饲料对若虫和成虫的发育、成活和生殖力均有不同程度的影响。米蛾成虫和米蛾卵的饲养效果最好。若虫期分别为19.1和16.3天,成虫获得率90.9％和88.5％;产卵前期3.1和3.9天,产卵量66.3和50.2粒,成虫寿命24和31天。不同饲料对下一代卵的孵化率和卵的发育期没有影响。对各种饲料原材料的成本作了估算,米蛾成虫是生产米蛾卵后的废弃物,充分利用可以大大减少黄色花蝽的繁殖费用。更多还原

【Abstract】 Comparative studies were conducted on mass rearing Xvlocoris flavipes. a predator of granary pests, on adult remains of rice moth (Corcyrs cephalonica), rice moth eggs, artificial eggs and rice moth eggs plus artificial eggs. The insect could complete its life cycle and oviposit on all tested rearing media. Different media, however, showed various effects on the mortality, development, and fecundity of X. flavipes. Results of the experiments demonstrated that the rice moth eggs and adult remains were the most superior compared to other media tested. No significant effect of the media was foun’d on egg hatchibility and incubation period of the descendant generation. Using adult remains of rice, moth is the most economical for mass rearing X. flavipes, for that they are wast products in mass production of rice moth eggs.更多还原
