1985～1990年六年在浙江、江苏二省五市(县)调查结果表明,野蚕黑卵蜂越冬代雌性比为59.92±10.93％,发生代为71.13±12.58％。各月间性比可有显著或极显著差异,而各地区间、各年度间则无显著差异。雌性比与母蜂交配率呈正相关,其线性关系式为:Y=-96.5057+1.8643x(r~2=0.9312)。雌性比与寄主卵块寄生率和卵粒寄生率均呈负相关,其线性关系式各为:Y=68.0765-0.2163x(r~2=0.8381),y=62.0456-0.3180x(r~2=0.5649)。发生代雌性比与寄主卵块大小的线性关系显著,其关系式为:y=69.4279+0.6360x(r~2=0.6654);越冬代则不显著。
The results of surveys in five cities (counties) of Zhejiang and Jiangsu provinces from 1985 to 1990 showed that the female ratio of overwintering on black silkworm oviposition was 59.92 ± 10.93%, and the incidence was 71.13 ± 12.58%. The monthly sex ratio can have significant or very significant differences, and across regions, no significant differences between the years. Female ratio and maternal mating rate was positively correlated, the linear relationship was: Y = -96.5057 + 1.8643x (r ~ 2 = 0.9312). The female ratio was negatively correlated with the parasitism rate and the parasitism rate of the host eggs, and the linear relationships were Y = 68.0765-0.2163x (r ~ 2 = 0.8381), y = 62.0456-0.3180x (r ~ 2 = 0.5649 ). The linear relationship between the size of the donor egg and the size of the host egg was significant. The relation was y = 69.4279 + 0.6360x (r ~ 2 = 0.6654), while the overwintering generation was not significant.
