| 本研究在实验室条件下测定了食蚜瘿蚊Aphidoletes aphidimyza 3龄幼虫对竹舞蚜Astegopteryx bambusifoliae 1~5龄若蚜的捕食功能?搜寻效应?自身密度干扰反应以及捕食偏好性, 以此评估食蚜瘿蚊对竹舞蚜的控害潜能?结果表明, 食蚜瘿蚊3龄幼虫对各龄期竹舞蚜的捕食功能反应均符合HollingⅡ功能反应模型?其对1~2龄竹舞蚜的瞬时攻击率最大(0.527); 对3龄竹舞蚜的处理时间最短(0.016 d), 捕食能力(21.5)和日最大捕食量(61.3)最大?食蚜瘿蚊3龄幼虫对不同龄期竹舞蚜的搜寻效应随着竹舞蚜密度的上升而下降?种内干扰反应试验结果显示, 随其自身密度的增加日均捕食量增加, 捕食作用率降低, 捕食者自身干扰作用增强, 种内干扰反应方程分别为:E=0.412 8P-1.323 2 (1~2龄), E=0.255 9P-1.205 0 (3龄), E=0.238 1P-1.442 3 (4龄), E=0.135 5P-0.966 6 (5龄)?同一空间密度条件下, 食蚜瘿蚊3龄幼虫对3龄?4龄竹舞蚜若蚜具有选择偏好性, 选择系数(Q)分别为1.75和1.05, 对其余龄期若蚜无选择偏好性?研究表明, 食蚜瘿蚊幼虫对竹舞蚜具有较好控害潜能? |
| 英文摘要: |
| The control potential of Aphidoletes aphidimyza in the prevention and control of Astegopteryx bambusifoliae was evaluated by examining the predation function, searching efficiency, self-density interference response and predation preference of the 3rd-instar larvae of A.aphidimyza on the 1st- to 5th-instar nymphs of A.bambusifoliae in laboratory conditions. The results showed that the functional response of the 3rd-instar larvae of A.aphidimyza to A.bambusifoliae conformed to a Holling typeⅡmodel, and the instantaneous attack rate of A.aphidimyza to the1st- to 2nd-instar of A.bambusifoliae was the highest (0.527), while its handing time for the 3rd-instar of A.bambusifoliae was the shortest (0.016 d), with the highest predation capacity (21.5) and daily maximum consumption (61.3 individuals) . The searching efficiency of A.aphidimyza gradually decreased with increasing density of A.bambusifoliae. The intraspecific interference test demonstrated a increasing daily predation, decreasing predation rate and growing interference effect with increase of self-density. The intraspecific interference equations are: E=0.412 8P-1.323 2 (1st- to 2nd-instar), E=0.255 9P-1.205 0 (3rd-instar), E=0.238 1P-1.442 3 (4th-instar), E=0.135 5P-0.966 6 (5th-instar). Under the same spatial density, the 3rd-instar larvae of A.aphidimyza showed an obvious predation preference for the 3rd- and 4th-instar nymphs of A.bambusifoliae, with selection index (Q ) of 1.75 and 1.05, respectively, and showed no preference for the other instar nymphs. The study suggests that A.aphidimyza larvae have good potential for controlling A.bambusifoliae. |
