摘　　要：在自然条件下调查湖北地区柑橘园中蚜虫种类,监测蚜虫及其自然天敌优势种群发生动态。连续的田间系统调查结果表明:为害柑橘的蚜虫有棉蚜Aphis gossypii、绣线菊蚜Aphis spiraecola、橘蚜Toxoptera citricidus、橘二叉蚜Toxoptera aurantii、豆蚜Aphis craccivora。其中,橘蚜和绣线菊蚜为优势种,全年可见,春末夏初和秋季为发生高峰期。本地天敌有蜘蛛Araneae、瓢虫Coccinellidae、食蚜蝇Syrphid、草蛉Chrysopidae、寄生蜂、蝽类Pentatomidae,当地蚜虫的主要捕食性天敌蜘蛛、瓢虫和食蚜蝇对蚜虫有较好的控制作用,发生动态紧随蚜虫种群数量变化。Aphids are major pests of a wide variety of commercially important plants in agriculture, horticulture and forestry.In the present study,we surveyed the population dynamics of aphid species and the dominant natural enemy species in citrus orchards in Hubei Province.The two-year successive survey under field conditions indicated that five species of aphid damaging citrus, including Aphis gossypii ,Aphis spiraecoLa .Toxoptera citricidus.Toxoptera aurantii and Aphis craccivora were found,and among which T. citricidus and A. spiraecola were dominant species.These two dominant species were present throughout the year and peaked in late spring, summer and autumn.The main natural enemies included spider,ladybug, hoverfly, lacewing, parasitoid, and stinkbug etc.Specifically , population increases of spider,ladybug and hoverfly often followed that of the aphids＇ , indicating strong top-down forces exerted by these natural enemies.
