摘要
选择3个不同抗虫性的玉米品种,研究了玉米品种抗虫性对玉米田节肢动物群落的影响。结果表明,玉米品种抗虫性对玉米田节肢动物群落的物种丰富度无明显影响,但对均匀度和多样性有明显影响,玉米品种抗虫性越高,节肢动物群落的均匀度和多样性越高。抗虫性较高的玉米品种田间益害比明显高于抗虫性较低的玉米品种。说明玉米品种抗虫性有助于提高玉米田节肢动物群落的稳定性和天敌对害虫的自然控制作用。
Three corn varieties with different levels of pest resistance were selected to study the effects of pest resistance of corn varieties on arthropod community in corn fields.The research results showed that pest resistance of corn varieties had no evident effects on the species richness but had obvious effects on the evenness and diversity of arthropod community in corn fields.The evenness and diversity of arthropod community and the ratio of natural enemies to pests in the fields of corn variety with relatively high level of pest resistance were higher than those in the fields of corn variety with relatively low level of pest resistance.These results indicated that the pest resistance of corn varieties was helpful to increase the stability of arthropod community and the natural control effect of natural enemies on insect pests in corn fields.
