| 中文摘要: |
| 有翅蚜产生是蚜虫适应环境变化的重要策略，多种因子诱导有翅蚜的形成。本文研究了温度、拥挤度、母代效应和天敌对棉蚜有翅蚜形成的影响程度。结果表明：在21~30℃温度范围内内，温度与翅蚜比例呈线性关系，21℃形成有翅蚜比例最高，约为10%; 棉蚜拥挤度与有翅蚜比例成正相关; 温度与拥挤度2因子的正交试验也进一步证实了低温、高拥挤度组合更有利于有翅个体的形成。母代效应对棉蚜F1代有翅蚜的形成有显著性影响，天敌胁迫促进有翅个体的形成。生物因子及非生物因子共同作用影响有翅蚜的形成，但在以后的研究中需要从分子水平上关注两者内在互作关系。 |
| 英文摘要: |
| Wing development in aphids is one of the important strategies for adaptation to environmental change; multiple factors influenced the percentage of aphid alates. The factors causing the production of alates in Aphis gossypii Glover were studied under laboratory conditions. The results indicated that there was a linear relationship between the percentage of alate and temperature from 21 ℃ to 30 ℃, and the percentage of alates developing at 21 ℃ was the highest. The crowding of the 1st instar nymphs was positively correlated with the proportion of alate production. By orthogonal test, the group with low temperature and high crowding produced more winged individuals. Maternal effects could have significant effects on F1 alate percentage. Moreover, predator induced stress produced a higher proportion of winged offspring. Alate development was affected by interactions between biotic and abiotic factors, and more attention should be paid to the correlations at the molecular level. |
