摘要
2009年对云南昭通不同类型苹果园绣线菊蚜的种群动态及其天敌群落组成进行了系统调查。按管理模式分成3类,每类型果园选取5棵12枝新梢的20个叶片进行害虫定枝调查,天敌调查采用树上目测、树盘扫网和诱集调查。结果表明,常规管理园绣线菊蚜的种群密度高于有机示范园和化学防治园;化学防治园绣线菊蚜的种群数量最低。三类果园天敌群落组成相似性差异较大,天敌物种数和个体数有机示范园均大于常规管理园和化学防治园,益害比最高达1.304。有机示范园的管理模式能较好的保护天敌,绣线菊蚜的种群密度也得到了很好得控制。
Population dynamics of Aphis citricola Van der Goot and the community structure of natural enemy in the different apple orchards in ZhaoTong City were investigated.According to the management mode into three types： each type of orchard select 5 tree of 12 branches of new shoots of 20 leaves investigation,survey of predators using tree visual and sweep and luring investigation.Population density of Aphis citricola conventional management is higher than the organic demonstration garden and chemical control orchard,chemical control orchard population density minimum.Natural enemy community compositions of three orchards had obvious difference.The results showed that,the population density was the highest in the routine management apple garden;the natural enemy species and individual number of the organic demonstration garden were higher than those of the conventional management garden and chemical control garden.Natural enemy species and individual numbers of organic demonstration garden are greater than routine management garden and chemical control orchard,the ratio of up to 1.304.Organic demonstration garden management mode can better protection from predators,population density of Aphis citricola has also been best control.
