Abstract

|
We investigated fertilization rate, hatchability rate, pupation rate and cocoon quality etc to selecting good characteristics of the wild silkmoth, Antheraea yamamai using method of indoor-and outdoor-rearing. As results of indoor rearing, the healthiness of A. yamamai was better in light green colour strain than that of dark green colour strain, but cocoon quality was better in dark green colour strain. There was a little effect to selecting major characteristics in grade of A, B and C strain classified with cocoon weight. $F_1$ hybrid was lower in fertilization rate and hatchability rate than parent, but higher in pupation rate and cocoon quality. There was no effect of heterosis in $F_2$ hybrid. In case of outdoor rearing, mortality rate was lower than that of indoor rearing but missing larva was higher. In addition, outdoor rearing is higher that indoor rearing in cocoon weight, cocoon shell weight and cocoon shell rate.
