| 摘 要： | 在小麦拔节到乳熟期内,麦长管蚜自然种群是以不同虫龄、不同翅型和不同体色蚜虫组成的混合群体.小麦拔节-孕穗和乳熟期以绿色有翅蚜为主,扬花-灌浆期以绿色无翅蚜为主.抗感两小麦品种上麦长管蚜自然种群在数量、翅型、虫龄和体色组成等方面差异显著.抗蚜品种上麦蚜种群数量显著低于感蚜品种；小麦灌浆期,抗蚜品种上成蚜比例和无翅蚜比例均显著低于感蚜品种.蚜虫自然种群体色结构分析表明,红体色麦长管蚜更喜取食感蚜小麦品种.结果表明,寄主生育期和寄主品种显著影响麦长管蚜种群结构.

| Abstract: | S.avenae population was a mixed population which was consisted of three parts: different insect states(larva instars),different wing forms and different body colors.The green wing aphid was the main body of the S.avenae population in the wheat jointing-booting stages and milk maturity.The green wingless aphid was the main body of the S.avenae population in the flowering-filling stages.There was significant difference between resistance and susceptible wheat varieties in S.avenae population size and populati... |
