Attacus atlas L. (Lepidoptera: Saturniidae) is one of Indonesian native insect that has a great potential economy. Fulfillment the demand of material for silk thread still rely that exist in nature, therefore, needs to be done with the use of intensive breeding male imago as effective as possible in mating. The aim of this research was to study the reproduction performance of male imagoes of wild silkworm A. atlas. This research was conducted by allow a male imago mate with three different females. The time of each mating was 6 hours. The parameters observed were the first, second and third ejaculate volume, the number of eggs per imago, egg hatching time and hatchability of eggs. The results showed that the frequency of mating significantly affect the percentage of egg hatchability. The optimum value was achieved at first mating was 53.58 ± 18.26%. The percentage of egg hatchability declined with increasing frequency of mating. The number of eggs per imago and egg hatching time was not influenced by the frequency of mating with the average number of eggs per imago 225.86 ± 34.23 eggs and the average time of hatching eggs was 11.20 ± 3.23 days
