| 摘 要： | 对不同密度条件下的扶桑绵粉蚧翅型分化进行了初步探讨.研究发现,扶桑绵粉蚧在温度25±1℃,湿度65％～80％,12 h全光照条件下,取食苗期棉花,种群在低密度时雌雄比例为0.31∶0.11,中等密度时雌雄比例为0.26∶0.17,高密度时雌雄比例为0.52∶0.48.由此可见,随着种群密度的增加,产雄的机率也随之增加. |

| Abstract: | Primary research on wing type differentiation of Phenacoccus solenopsis Tinsley under equivalent environment condition(25±1℃,65%~80%RH,12 hours full light and feed by cotton seedling),and different densities was studied..The results showed that female and male proportions were 0.31∶ 0.11 under low population density,0.26∶ 0.17 under middle population density,and 0.52∶ 0.48 under high population density.The results indicated that the birth rate of male was increased with the population density. |
