摘要
通过单头隔离和群体饲养黄粉虫成虫观察其产卵量的差异。结果表明：在温度22～28℃及45～65％RH室内饲养条件下，黄粉虫雌雄比是1：1．33．黄粉虫产卵多集中在前40天，40天之后产卵量下降明显，在整个产量期内有明显的阶段性。不同饲养条件下黄粉虫产卵量差异较大。在单头饲养过程中发现产卵量最少仅有3枚／头，有的可多达189枚头，平均17．6枚／头，群体饲养条件下产卵量平均182．02枚／头。
The study aims to probe into the amount of spawned eggs of tenebrio molitor, by means of comparing adult sex ratio and raising mode. The results indicated that the average adult sex ratio （22℃-28℃ and 45%-65% RH） was 1：1.33. Newly emerged females beeame sexually active and begin to oviposit after 3-5 days. The developmental time of eggs was mostly 5 -40 days, and the reproductive capacity decreased after 40 days. There were substantial variation in the number of born eggs per female in different raising modes.
