【摘要】 害虫生态调控是近年来备受关注的有害生物防控策略，针对北方稻田主要害虫实施了几项害虫生态调控措施，通过定期调查主要害虫稻飞虱种群数量、二化螟为害的白穗发生情况以及稻田蜘蛛种类与数量情况，评价了该技术的控害效果及对天敌蜘蛛群落组成的影响,结果表明，害虫生态调控对稻飞虱和二化螟的控制效果与常规施药对照田相当，差异不显著，对稻田蜘蛛的保护和利用效果明显，调控田蜘蛛总数量（1 629头）显著高于对照田（1 309头）。更多还原

【Abstract】 In recent years, ecological pest control has attracted much attention. Several ecological pest control measures were carried out for the main pests in the northern rice fields. We investigated the population of rice planthopper, the ratio of white ear of rice affected by Chilo suppressant(Walker), and the species and number of spider in rice field, in order to evaluate the effect of this technique on pest controlling and spider community composition. The results showed that the effect of ecological pest control on rice planthopper and Chilo suppressant(Walker) was similar to the contrast rice paddies, and the difference was insignificant. The total number of spiders in the rice field of ecological pest controlling(1 629) was significantly higher than that in the contrast rice paddies(1309).更多还原
