摘要 通过不同氮水平处理,研究瓜蚜Aphis gossypii生殖力、黄瓜叶片游离氨基酸、可溶性糖含量的变化,探讨施肥水平与蚜虫繁殖的关系。结果显示,高氮水平(210、280mg/L)处理瓜蚜生殖力明显高于低氮水平(70、140mg/L)处理,其中140 mg/L氮水平处理,蚜虫的内禀增长率、单雌平均每日产仔量、净增值率等最低,种群数量增加量最小;不同氮水平处理黄瓜叶片内游离氨基酸和可溶性糖含量有明显变化,随着氮水平增加,16种游离氨基酸的总量增加、可溶性糖的含量降低;蚜虫内禀增长率与叶片内游离氨基酸增加量和对照增加量的比值呈现正相关,与可溶性糖的含量呈负相关,且均达到显著水平。结果表明不同氮水平通过改变叶片内游离氨基酸和可溶性糖的含量而影响蚜虫的繁殖和种群的增长。 Fecundity of aphid Aphis gossypii,the amount of foliar soluble sugar and free amino acids in cucumber were studied under different nitrogen solution levels to explore the relationships between nitrogen fertilizer application and cucumber aphid fecundity.The results showed that the fecundity of aphid was significantly higher on 210mg/L and 280mg/L nitrogen solution levels than that on 70mg/L and 140mg/L nitrogen solution levels.Intrinsic rate of increase,single female daily fecundity,net value-added rate and the mount of population increase were the lowest on 140mg/L nitrogen level.With the increase of nitrogen solution levels,the contents of foliar soluble sugar and soluble amino acid of cucumber changed significantly that the total amount of 16 kinds of soluble amino acid increased while the content of soluble sugar decreased.Intrinsic rate of increase of cucumber aphid was significantly correlated with the ratio of the increase amount of foliar free amino acids to the control,while significantly negative correlated with the amount of soluble sugar.The results indicated that different nitrogen fertilization affected fecundity and population growth of aphid by changing the amount of foliar soluble amino acids and soluble sugar.
