“蜂-蛙-灯”绿色生产技术对水稻害虫、天敌及产量的影响

摘要

Effects of integrated prevention and control measure of trichogrammae-bullfrog-trap lamp on populations of insect pests and their natural enemies in paddy field were investigated in Hunan province.The results indicated that pollution-free production technology of trichogrammae-bullfrog-lamp had a relatively better control effects on rice planthoppers and Cnaphalocrocis medinalis (Guenee),and which had little effect on spiders and Cyrtohinus lividipennis (Reuter).There was no significant difference between trichogrammae-bullfrog-lamp area and chemical control area on the rice yield.Therefore,this technology has a good prospect of application and extension because it is a new mode of ecoagriculture and could reduce pesticide use and protect the environment.%采用赤眼蜂、蛙类和诱虫灯等为主的集成防控措施,对水稻害虫和天敌种群发生的影响.结果表明:“蜂-蛙-灯”绿色生产技术对稻飞虱和稻纵卷叶螟有较好的控制效果,对蜘蛛和黑肩绿盲蝽影响较小或无影响,且“蜂-蛙-灯”防治区的水稻产量与化学防治区无显著差异;随着该技术连续3年示范,稻飞虱和稻纵卷叶螟逐年减少,水稻产量逐年增加.该技术模式减少了化学药剂的使用,保护了生态环境,是一种新型的生态农业模式,具有广阔的推广应用情景.
