Abstract

The longevity and emergence of male and female adults of Dirhinus anthracia and Trichopria sp. from uzifly pupae, fed on various diets such as water, 10% glucose, 10% sucrose, 10% jaggery, 10% honey, 10% yeast and 100% honey used for control were investigated. The life span of males and females of D. anthracia was highest when fed with 100% honey and least on water. The longevity of males and females of Trichopria sp. was better on 10% honey compared to other diets. But the survival rate of males and females of Trichopritz sp. was least in control batches (100% honey). The emergence of male and female adults of D. anthracia was very high in control batches when compared to otber diets. But it was least on Water in females and on yeast in males. The emergence of males and females of Trichopria sp, was more on sucrose and very poor on 100% honey.
