中文摘要:
      通过对新疆阿克苏3类主栽模式核桃园系统调查发现:核桃黑斑蚜的天敌主要有草蛉、黑食蚜盲蝽、食蚜蝇、多异瓢虫和蜘蛛;间作作物对核桃黑斑蚜及其天敌的发生均有一定的影响;在核桃黑斑蚜发生初期,在核-麦-玉式核桃园中益害比最大,草蛉和蜘蛛发生量最多,种群数量分别为6.60头/百叶、0.20头/百叶,间作小麦最有利于增益控害,其次是间作棉花;在中后期,草蛉、多异瓢虫在核-棉式核桃园发生量较多,种群数量分别为6.01头/百叶、0.64头/百叶;黑食蚜盲蝽在核-麦-玉式核桃园中发生量较多,种群数量为1.08头/百叶;食蚜蝇和蜘蛛在无间作核桃园中的发生量较多,种群数量分别为0.51头/百叶、0.91头/百叶;但天敌不能阻止核桃黑斑蚜的大量发生,其种群数量在7月中旬达到高峰,平均种群数量达3000头/百叶以上。
英文摘要:
      The three planting patterns of walnut were investigated and the result showed that the major natural enemies of the walnut aphid (Chromaphis juglandicola (Kaltenbach)) were green lacewings, Deraeocoris punctulatus Fall, syrphid flies, Hippodamia variegata (Goeze) and spiders. Intercrops had a certain influence on the walnut aphid and the natural enemies. In the early stage of the occurrence of the walnut aphid the population number of Green lacewings and spiders were the largest in the walnut-wheat-maize intercropping orchard, being 6.60 and 0.2 individuals per one hundred leaves. Intercropped wheat was better than intercropped cotton and unintercropping on the control of pest and the proliferation of natural enemies. In the middle later stage the population of green lacewings (6.01 individuals per one hundred leaves) and H. variegate (0.64 individuals per one hundred leaves) in the walnut-cotton intercropping orchard,D. punctulatus(1.08 individuals per one hundred leaves) in the walnut-wheat-maize intercropping orchard, spiders(0.51 individuals per one hundred leaves) and syrphid flies (0.91 individuals per one hundred leaves) in the walnut orchard without intercropping were larger than those in the other orchards. But the natural enemies didn't control the growth of the walnut aphid. The population number of the walnut aphid reached the maximum in the middle of July, and was over 3000 individuals per one hundred leaves.
