Improvement of Occasional Artificial Hatching and Incubation Method in Diapause Egg of the Wild Silkmoth, Antheraea yamamai
Abstract
We investigated starvation of hatching larvae, occasional artificial hatching and incubation method to establish year-round rearing of the wild silkmoth, Antheraea yamamai. In the test of starvation of hatching larvae for brushing at a time, the survival rate of the fourth instar of larvae starved for 1 day after hatching in 25℃ and 5℃ was 83.3% and 96.0%, respectively. The result represents that the survival rate is high at low temperature during starvation. In the occasional artificial hatching test for multi-times rearing of A. yamamai, the useful hatchability is high at 5℃ in case of preserving eggs for 2 months from incubation time, and at both 2.5℃ and 0℃ in case of over 6 months. A new incubation method with pre-incubation at 15℃ and 24 D photoperiod showed high hatchability about 80% for only 2 days compared with hatching for 5-6 days in traditional incubation method with the preservation at 25℃.
