摘 要:【目的】为明确苹果园种植绿肥后天敌昆虫与植食性害虫的发生动态。【方法】于2020年3-4月采用马氏网对陕西延安2种果园绿肥种植模式中的昆虫进行调查,并量化分析各昆虫功能团多样性及分布特征。【结果】共捕获4428只昆虫,隶属于7目39科43种,其中绿肥油菜(YC)种植模式捕获26种1046只昆虫,优势种为豌豆潜叶蝇Chromatomyia horticola。绿肥毛叶苕子(MS)种植模式捕获36种3382只昆虫,优势种为瘿蚊Diarthronomyia chrysanthemi。油菜种植模式各功能团昆虫群落Shannon-Wiener多样性(F=24.68,P<0.0001)及Sa/Si稳定性指数(F=16.24,P<0.0001)均显著高于毛叶苕子种植模式。典范对应分析(CCA)表明毛叶苕子种植模式下捕食性天敌昆虫与植食性害虫物种数和个体数均高于油菜种植模式。【结论】油菜种植模式下昆虫群落稳定性更强;天敌昆虫与植食性害虫物种数相互制约,个体数存在相似消长规律。本研究明确了不同绿肥配置模式下果园昆虫分布特征及功能团多样性,为果园绿肥推广及有害生物绿色防控提供依据。[Objectives]To investigate the population dynamics of the natural predators of pest insects in apple orchards planted with different companion plants.[Methods]Insects in two orchards planted with different companion plants in Yan'an,Shaanxi province were monitored using the Markov net method from March to April in 2020,and the diversity and distribution of each functional insect group was quantified and analyzed.[Results]A total of 4428 individual insects were collected,which were classified into 43 species,39 families and 7 orders.1046 individual insects(26 species)were captured in the orchard co-planted with rapeseed(YC).The dominant species in this orchard was Chromatomyia horticola.3382 individual insects(36 species)were captured in co-planted with Vicia villosa(MS).The dominant species in this orchard was Diarthronomyia chrysanthemi.The Shannon Wiener diversity and Sa/Si stability index of the YC orchard were significantly higher than those of MS orchard.Canonical correspondence analysis(CCA)shows that the diversity and abundance of predatory species and herbivorous pests were higher in the MS than in the YC orchard.[Conclusion]The insect community was more stable in an orchard co-planted with rapeseed than in one co-planted with V.villosa.The diversity of predatory species and herbivorous pests were positively correlated and there was a similar correlation between the individual abundances of these groups.These results clarify the distribution and diversity of functional insect groups in two different companion plant crops in apple orchards,which provides information for selecting suitable companion plants for apple orchards and the prevention and control of apple pests.
