不同引诱剂对果实蝇诱杀效果对比试验

为筛选经济、增效、低毒的果实蝇引诱剂,在前人开发引进果实蝇诱捕器灭雄技术并取得成效的基础上,使用5种不同处理的引诱剂对果实蝇进行诱杀效果对比试验。结果表明,果实蝇性引诱剂添加蜜糖后形成的混配剂对果实蝇成虫的诱杀效果最好,是一种既经济又增效的复配型引诱剂;在果实蝇性引诱剂中添加酒、醋后也能提高诱杀效果;而在没有果实蝇性引诱剂的作用下,糖醋酒3种混合液对果实蝇诱杀效果极低,可视为一种无效的引诱剂。

Trapping effects of different attractants on Bactrocera dorsalis

In order to screen the economic and effictive attractants,the experiments were conducted to study the trapping effects of five attractants on Bactrocera dorsalis in different treatments.The results showed that the sexual attractant of Bactrocera dorsalis added with honey had the best trapping effects to Bactrocera dorsalis adults,which was an economic attractant with multiple efficiencies.The sexual attractant of Bactrocera dorsalis added with alcoholics and vinegar also could enhance the trapping effects.But without the sexual attractants of Bactrocera dorsalis,the mixture of sugar,vinegar and alcoholics had little trapping effects on Bactrocera dorsalis,which could be regarded as an ineffective attractant.
