摘　　要：［目的］研究洞庭、碧波原蚕在贵州地理环境和气候条件下的性状表现。［方法］将洞庭、碧波原种催青收蚁后，以一日四回育为对照，设二回育和三回育2个试验区，各3次重复，小区蚁量1 g，于2009年春季开展全龄不同饲育回数的试验研究。［结果］全龄不同饲育回数对洞庭、碧波原蚕的发育经过没有明显影响，但对碧波原蚕的幼虫生命力和发育整齐度影响较大。其中，发育整齐度和眠起情况均以二回育区最不整齐，小蚕发生率为2.43%，分别是三回育和四回育的2.25、2.93倍；4～5龄期发病率和蔟中死蚕率均为0.50%，分别比三回育和四回育各高出0.32、0.17和0.32、0.17个百分点。洞庭品种4龄结茧率各处理间差异不显著，碧波品种4龄结茧率三回育和四回育与二回育之间均存在显著差异；洞庭、碧波品种对4龄健蛹率各处理间差异不显著；洞庭品种单蛾产卵量和单蛾良卵数四回育和三回育与二回育之间均存在显著以上差异，碧波品种各处理间产卵成绩差异不显著；洞庭、碧波品种单蛾不受精卵数和单蛾死卵数各处理间差异不显著。［结论］在贵州春季气候环境和桑叶基础条件下，洞庭、碧波原蚕采用全龄一日三回育完全可行，二回育不宜采用。[ Objective] The research aimed to study character performance of parent silkworm variety of Dongting and Bibo in Guizhou. [ Method] The parent silkworm variety of Dongting and Biho were induced mature and fed newly hatched larvae. Two, three and four feeding per day treatments of three times repeated were designed, and one feeding treatment was as the contrast. Each treatment had 1 g newly hatched larvae. The test of different rearing times of total instars was carried out in Spring of 2009. [ Result] There were no significant effects of different rearing times on the developmental duration of parent silkworm variety of Dongting and Bibo, but there were big effects on the survival ability of larvae and the developmental regularity on parent silkworm variety of Bibo. The developmental regularity and the breaking sleep situation of two feeding per clay treatment of parent silkworm variety of Bibo were most out of order. Thereinto,＇the ratio of young silkworm was 2.43% , was the 2.25, 2.93 times of three and four feeding per day treatments, and the incidence of 3 -4 days silkworm was 0.50%, was 0.32, 0.17 and 0.32, 0.17 percent higher than three and four feeding per day treatments. There was no significant difference in the cocooning rate of 4 days parent silkworm variety of Dongting among different treatments, but there was significant difference in the cocooning rate of 4 days parent silkworm variety of Bibo between three and four feeding per day treatments and two feeding per day treatment. There was no significant difference in the 4 days ratio of survival pupa among different treatments of parent silkworm variety of Dongting and Bibo. There was over significant difference in the egg laying amount per moth and the good egg amount per moth between three and four feeding per day treatments and two feeding per day treatment of parent silkworm variety of Dongting, but there was no significant difference in laying egg performance among different treatments of parent silkworm variety of Bibo. There was no significa
