| 摘 要： | 本文研究了大田条件下施用吡虫啉、氧乐果对烟田节肢动物群落的影响,施药后害虫和天敌的种群消长动态,并以多样性、相似性指数等生态学参数来衡量2种杀虫剂产生的生态效应及对烟田节肢动物群落时空分布的影响.结果表明,施用氧乐果田块的节肢动物各类群数量都明显下降,天敌恢复较为缓慢,而害虫类恢复则较快,群体数量的急剧变化使得群落稳定性降低;施用吡虫啉的田块,蚜虫、叶蝉等刺吸式口器害虫数量明显下降且不易恢复,天敌类则相对下降不大.初步认为,使用选择性杀虫剂吡虫啉对烟田生物群落物种数量的恢复与保持群落的自我调节能力与自然控制力有重要作用.

| Abstract: | Field samples were taken to determine the effect of the insecticides on Arthropod community in tobacco field. Omethate is disadvantageous to all Arthropods, it make all species' number decrease and reduces the stability of the community. Imidacloprid is beneficial to control the main pests and protect the natural enemies. It is beneficial to spray selected insecticides to remain the natural control of pests. |
