【摘要】 2005~2007年引进频振式杀虫灯,在无公害香芋生产上的应用研究表明:4月上旬~5月初起始挂灯,灯距地高约1.5 m或较香芋植株高10~20 cm,可诱虫8目39科,益害比为1∶(25.32~215.92),随着挂灯年限延长,害虫基数下降。对金龟甲诱捕灵敏度达93.97%~100%,校正保芋效果达82.32%,虫孔指数下降82.02%;防治斜纹夜蛾效果与化学防治差异不显著,可替代化学防治,解决抗药性问题。防治香芋害虫效果与害虫种类、气候因素、生态环境、组合技术、人为因素等因子相关。更多还原

【Abstract】 The application of the frequency vibrancy-killing lamp in the production of pollution-free fragrant-taro was studied.The results show that: the lamp is starting lights in the first ten days of April to the beginning of May,its height is about 1.5 m or higher than the fragrant-taro plants by 10～20 cm,it can tempt the insects of 8 head 39 branch.The ratio of natural enemies of insect pests and insect pests is 1∶(22.62～215.92).With the fixed number of year of use is extending, the pests base is declined.The sensitivity of its trapping the chafers can reach 93.97%～100%,the correction protection result to the fragrant-taro can reach 82.32%, the insect hole index drops 82.02%.The difference between its preventing and controlling prodenia litura effect and chemistry preventing and controlling is not singnifcant,but it may substitute chemistry preventing and controlling,and solve the problem of resistance to drugs.The effect of its controlling fragrant-taro insect pests is related with the pest species,climatic factor,ecological environment,combination technology and human factor.更多还原
