颜色和糖醋液对番石榴实蝇引诱效果

[目的]防治番石榴实蝇的危害。[方法]在室内研究的基础上,进一步研究不同颜色和不同浓度的糖醋液对田间番石榴实蝇的诱捕效果。[结果]试验结果表明,糖醋液(2.5%∶12.5%∶25.0%)对雌虫的引诱效果显著地高于其他糖醋液浓度和对照。糖醋液(2.5%∶12.5%∶25.0%)对雄虫的引诱效果显著地高于经验值糖醋液(10.0%3∶0.0%∶10.0%)和对照。在不同颜色对田间番石榴实蝇的诱捕中,红色和黄色与对照均存在显著差异,红色的引诱效果显著地高于黄色。[结论]糖醋液(2.5%1∶2.5%2∶5.0%)和红色对番石榴实蝇有显著的引诱效果。

Effect of the Color and the Solution of Sweet Bait on the Common Guava Fruit Fly

[Objective] The damage of the fruit fly to common guayava was controlled through the experiment.[Method]Based on the experiment in lab,the effect of the different colors and concentrations of the solution of sugar and vinegar on the common guayava fruit fly-capturing and killing in field condition was researched.[Results]The results showed that the effect of the solution of sugar and vinegar(2.5%∶ 12.5%∶25.0%) on female insect-attracting was significantly better than that of other concentrations of solution and the control;and also,on male insect-attracting,significantly better than that of traditional treatment solution(10.0%∶ 30.0%∶ 10.0%) and the control.Color in different guava fruit on the trap field,The effect of the red color on insect-attracting was significantly higher than that of the yellow color.[Conclusion] The solution of sugar and vinegar(2.5%∶ 12.5%∶ 25.0%) and the red color could produce the significant effect on common guayava fruit fly-capturing and killing.
