Abstract

This study aims to describe various morphometric parameters of male A. atlas moth, to found a correlation between the morphometric parameters and body weight on male moths, and to describe the reproductive system of male A. atlas moth. Male can distinguish from the female by comparing the antennae. The antennae of male is wider. There is a very strong correlation between the total body length and the body weight in linear equation Y = 0.875 X-1, 639 when Y is the weight in grams and X is the total body length in cm. Reproductive system of male A. atlas moth generally similer to B. mori reproductive system. Male A. atlas moth has reproductive system consists of a pair of testes, a pair of deferent duct with ampula ductus deferent, one spermatophore gland, one alba gland, one prostatica gland and one penis.
