Attacus atlas L. (Lepidoptera: Saturniidae): a new record on Ailanthus excelsa Roxb. from Assam, India.
The natural incidence of the saturniid wild silk moth, Attacus atlas L. recorded feeding on "Tree of Heaven", Ailanthus excelsa Roxb. plantations at Jorhat, Assam, India. The incidence of the wild silk moth recorded throughout the year with peak incidence during May-October. The average cocoon weight was 14.11 g and 10.29 g for male and female, respectively. The average shell weight of single cocoon recorded 2.04 g and 1.84 g for female and male, respectively which is five times more than shell weight of domesticated eri silkworm, Samia ricini. The scope and prospects for commercial exploitation of this wild moth has been highlighted in this study.
