Environmental Controlling Factors of Tasar Silkworms Antheria mylitta Drury (Lepidoptera : Saturniidae)

Abstract

The paper deals with the ovipositioin, hatchability, fecundity larval and pupal performances of a tropical variety of tasar silkworms Antheria mylitta Drury (Lepidoptera : Saturniidae). The Tasar silkworms have been cultured feeding on the leaves of Arjun (Terminalia arjuna) in the laboratory at temperature 30°C and humidity 86% which has been recorded congenial for the hatching of the larvae. It was estimated that a potent female laid 285 eggs which are all variable and hatched into first instar larvae i.e. of 7 days each. Such a high reproductive potential of tasar silkworms will be beneficial for tasar production which has high value in the trade and commerce.
