摘　　要：为明确花生-玉米间作种植模式对蓟马类害虫的控制效果,通过3年田间试验系统调查花生单作、玉米单作和花生-玉米间作3种种植模式下蓟马及其主要捕食性天敌东亚小花蝽Orius sauteri的种群数量动态特征及不同种植模式下东亚小花蝽和蓟马的益害比。结果显示,花生-玉米间作种植模式下东亚小花蝽种群密度显著高于花生单作种植模式,花生-玉米间作种植模式下82.94%以上的东亚小花蝽来源于玉米斑块;与2种单作种植模式相比,花生-玉米间作种植模式未显著减少蓟马的种群密度;东亚小花蝽种群密度与蓟马种群密度呈显著线性关系;花生-玉米间作种植模式下东亚小花蝽与蓟马的益害比均显著低于其他2种单作种植模式。表明花生-玉米间作种植模式在局域农田小范围空间尺度下能显著提高捕食性天敌的种群密度,但并不能显著减少蓟马类害虫种群数量。In order to determine the biocontrol efficacy of peanut-maize strip intercropping against thrips,a three-year field experiment was conducted to investigate the population dynamics of thrips,its main predator Orius sauteri and the ratio of beneficial natural enemies to pest insects in monoculture and intercropping systems.The results indicated that,compared with the peanut monoculture system,peanut-maize intercropping systems significantly increased the density of O.sauteri,and more than 82.94% of the predators occurred in the maize patches in the intercropping system.However,peanutmaize intercropping did not significantly reduce population density of thrips compared with monoculture systems.A linear relationship existed between the population densities of O.sauteri and thrips.The density of O.sauteri increased with increasing density of thrips.The ratio of beneficial natural enemies to pest insects in the intercropping system was significantly lower than that in monoculture systems.These results indicated that the peanut-maize strip intercropping could significantly enhance the population density of predatory natural enemies,but could not significantly reduce thrips in the local landscape.
