摘要: 为明确食蚜瘿蚊对豌豆修尾蚜的控害能力,在实验室条件下测定食蚜瘿蚊1~3龄幼虫对豌豆修尾蚜1~2、3、4龄若蚜的捕食功能、种内干扰及其捕食偏好性。结果表明,食蚜瘿蚊1~3龄幼虫对不同龄期豌豆修尾蚜的捕食功能反应均为Holling Ⅱ型。食蚜瘿蚊3龄幼虫对豌豆修尾蚜1~2龄若蚜捕食能力最强,为16.23头/d,对3龄若蚜、4龄若蚜次之,捕食能力分别为12.05、10.55头/d;食蚜瘿蚊1~3龄幼虫对豌豆修尾蚜1~2龄若蚜的日最大捕食量分别为29.24、24.88、22.57头/d;食蚜瘿蚊各龄期均偏好捕食1~2龄若蚜,选择系数分别为1.67、1.42和1.31。食蚜瘿蚊对豌豆修尾蚜的总捕食量随自身密度增大而增大,但单头捕食量和捕食作用率随着自身密度的增大而下降,其捕食作用率E与自身密度P的关系模型分别为E1=0.2279p-0.519E2=0.2093p-0.550E3=0.2022p-0.527。研究表明食蚜瘿蚊对豌豆修尾蚜各龄若蚜均有一定的控害能力,为食蚜瘿蚊对豌豆修尾蚜的防控提供了理论基础和数据支撑。

Abstract: To determine the predation capacity of Aphidoletes aphidimyza to Megoura crassicauda, the functional responses of A. aphidimyza to M. crassicauda at different stages, the prey selection of A. aphidimyza on M. crassicauda at different stages and the interference effect of the density of A. aphidimyza on its predation capacity were studied in the laboratory. The results showed that the functional response of A. aphidimyza to each developmental stage of M. crassicauda was all fitted to the Holling II model. The predation capability of A. aphidimyza on young nymphs aged 1―2 of M. crassicauda was the strongest with a value of 16.23, followed by the 3rd instar nymph and the 4th instar nymph, with a value of 12.05 and 10.55, respectively. The daily maximum predation amount of A. aphidimyza on 1st―2nd instar nymph, 3rd instar nymph and 4th instar nymph of M. crassicauda were 29.24, 24.88, and 22.57. A. aphidimyza has a strong preference for the 1st―2nd instar nymph of M. crassicauda, with a selection coefficient (Q) of 1.67, 1.42, and 1.31, respectively. The total predation amount of A. aphidimyza on M. crassicauda increased with the density of A. aphidimyza, but the predation amount per predation number and predation rate decreased with the density of A. aphidimyza. The relationship between the rate and the density of A. aphidimyza were in line with the model E1=0.2279p-0.519, E2=0.2093p-0.550 and E3=0.2022p-0.527, respectively. The results showed that A. aphidimyza had strong predation capability in each of the different developmental stages of M. crassicauda. This provides a theoretical foundation and data support for the pest control of M. crassicauda by A. aphidimyza.
