| 摘 要： | 为了明确种群密度对棉蚜(Aphis gossypiiGlover)转主取食适合度的影响,通过室内转接试验,研究了采自棉花和黄瓜的棉蚜品系分别以不同种群密度转接到棉花和黄瓜上的成虫留居率和种群增长率。结果表明:种群密度对于两品系棉蚜的成虫留居率均没有显著影响;在不转换寄主的情况下(棉花品系/棉花、黄瓜品系/黄瓜),种群密度对于两品系的种群繁殖率均没有显著影响;寄主转换后(棉花品系/黄瓜、黄瓜品系/棉花),种群密度对两品系的种群繁殖率有显著影响,均表现为以30头/株转接,种群繁殖率显著高于以10、50、70头/株转接,而后三者之间没有显著差异(P>0.05);棉花品系/棉花的种群适合度显著高于棉花品系/黄瓜种群,黄瓜品系/黄瓜的种群适合度显著高于黄瓜品系/棉花种群。 |

| Abstract: | In order to define the effect of population density on the fitness of Aphids gossypii Glover after host plant transplantation,the colonizing rate of adults and reproductive rate of the population of both cotton and cucumber strains transplanted to cotton and cucumber in different densities were investigated by laboratory host plant transplantation experiment.The results showed that population density had no significant effect on the colonizing rate of adults of both cotton and cucumber strains;population de... |
