泛蚁蛉幼虫饲料及饲食频率的选择研究

摘要

研究比较了泛蚁蛉幼虫取食3种饲料后的发育历期、存活率、性比以及对蝇蛆和黄粉虫的利用率;比较了泛蚁蛉在蝇蛆不同饲食频率下的发育历期、存活率.结果表明取食蝇蛆和黄粉虫的泛蚁蛉幼虫的发育历期短,存活率高,性比接近于1;泛蚁蛉幼虫对蝇蛆的利用率高于黄粉虫;泛蚁蛉幼虫在蝇蛆1日一饲和3日一饲的频率下发育历期短,存活率高.%The development periods, survival probability and sex ratio of M. formicarious Linnaeus with 3 different feeds, and the utilization rate of feeding maggot and tenebrio molitor were compared in this study. The larval developmental period, survival probability of feeding maggot were analysed in different feeding frequency. The results showed that the larval developmental period of M. formicarious Linnaeus of feeding maggot and tenebrio molitor was shorter than others, but its survival probability was higher and the sex ratio was closed to 1. The utilization rate of feeding fly larvae was higher than tenebrio molitor. Under conditions of once feeding a day and once feeding every three days, the ant lion had short development times and high survival rate.
