摘要
对单配或一雄多雌或经历不同交配历期的雌黄粉虫 Ｔｅｎｅｂｒｉｏ ｍｏｌｉｔｏｒ Ｌ．产卵量进行了研究，以期了解两性的繁殖力，为雌虫多产高质量卵提供科学依据。在幼虫期添加少量鲜马铃薯可极大地促进其生长。适当的高密度和不筛粪有利于低龄幼虫生长，４０日龄以后应定期筛粪并添加新饲料。幼虫的最适密度取决于其拥有的饲料量。幼虫生态生长效率高达３１．８％。
The numbers of eggs laid by the females of Tenebrio molitor L. reared monogamously, monarsenously and with different mating durations are surveyed to assess the fertility of each sex and provide scientific basis for inducing females to lay more high quality eggs. And in the larval stage,small amount additional fresh potatoes may promote the larval growth greatly. The growth may also be facilitated by keeping the larvae in suitable high density and frass is not screened when the larvae are younger than 40 days old,and after that frass should be screened and new bran added regularly. The optimal density depends on the feed quantity offered for certain larvae. The ecological growth efficiency of larvae is as high as 31. 8%.
