The Effects of Diet on the Longevity and Fecundity of Fopius arisanus Sonan

The effects of diet(sugar feeding) on the longevity,fecundity of F.arisanus were investigated in this paper.The results showed that diets and host provision could significantly influence the longevity of adult F.arisanus.The mean longevity of adult female parasitoids was(37.8±1.1) d when deprived of host eggs,which was only(19.2±3.8) d when host eggs were provided.The adult longevity of female was no longer than one week whether host eggs were provided or not when honey was deprived.Honey + water feeding could significantly enhance the fecundity,and the female ratio of the offsprings was also significantly increased when fed with honey + water.
