摘要
为了解广西地区利用赤眼蜂防治甘蔗螟虫的田间效果和综合效益,为广西甘蔗螟虫防治工作提供依据并促进生物防治螟虫技术的进一步推广,本试验通过放蜂区与常规防治区的对比,调查了释放赤眼蜂对甘蔗螟虫的防效及对甘蔗生物学性状、产量及理论蔗糖分的影响,并同时分析了释放赤眼蜂的综合效益。结果显示,与常规防治方法相比,释放赤眼蜂能使螟害节率降低84.04%,螟害株率降低57.21%,断尾率降低57.29%;放蜂区甘蔗株高更高,茎更粗,植株生长更好;理论产量提高了12.07%,理论蔗糖分提高了1.17%;放蜂区农药减量明显,经济收入更高,农民对放蜂防螟的满意度高。
To understand the field effect and comprehensive benefit of sugarcane borer control using trichogramma,provide a reference for promoting the biological control of sugarcane borer in Guangxi area,we set trichogrmma control and conventional control plots for comparison,and investigated the effects of trichogramma releasing on the borer control and the biological characters,cane yield and theoretical sucrose content in cane,and analyzed the comprehensive benefit.Results showed that,as compared with conventional control,trichogramma releasing decreased the rate of borer damaged internodes by 84.04%,the rate of borer damaged plants by 57.21%,and the rate of broken top stalks by 57.29%;the plant height was taller,the stalks were thicker,and the plants grew better;the theoretical cane yield increased by 12.07%,and the theoretical sucrose content in cane increased by 1.17%;the pesticide application rat decreased dramatically,the economical income increased,and the degree of satisfaction on trichogramma releasing was high from the farmers.
