摘要:

【目的】筛选诱集烟蚜重寄生蜂的适宜颜色和糖酒醋液,为烟蚜重寄生蜂的防治及烟蚜茧蜂规模化繁殖提供参考依据。【方法】对烟蚜茧蜂繁蜂棚内重寄生蜂的发生数量动态进行调查,记录烟蚜茧蜂和重寄生蜂的羽化数量,计算羽化率和重寄生率;设6个不同糖酒醋液和5种不同颜色处理对重寄生蜂进行诱集,记录诱集到的重寄生蜂及其他昆虫数量,比较不同糖酒醋液和不同颜色对烟蚜重寄生蜂的诱集效果。【结果】在繁蜂中后期,重寄生蜂数量增多,8月重寄生率可达54.33%,11月降低至28.00%;不同糖酒醋液诱集到的重寄生蜂数量差异不显著(F=0.23,P>0.05);各颜色诱集到的重寄生蜂数量差异显著(F=25.71,P<0.05),其中以黄色诱集效果最佳,黄色杯共诱到925头重寄生蜂,占诱集总数的51.13%;其次为白色,共诱到373头重寄生蜂,占诱集总数的20.62%。【结论】生产中可利用黄色杯装糖酒醋液对烟蚜重寄生蜂进行诱集,以提高烟蚜茧蜂的规模化繁殖效率。

【Objective】The suitable colors, mixed liquid with sugar, wine and vinegar for trapping hyperparasitoids in mass rearing greenhouse of Aphidius gifuensis was selected, in order to provide basic reference for hyperparasitoids control and mass rearing of A. Gifuensis. 【Method】Population dynamics of hyperparasitoids in rearing greenhouse for A. gifuensis was surveyed, emergence numbers of A. Gifuensis and hyperparasitoids were recorded and the emergence rates and hyperparasitism rate were calculated. Six different mixed liquids with sugar, wine and vinegar and five different colors were designed for trapping hyperparasitoids. The hyperparasitoids and other insects trapped were recorded and the effects of different treatments were compared. 【Result】At middle and later periods of mass rearing, the number of hyperparasitoids increased, and the proportion reached 54.33% in August, decreased to 28.00% in November. No significant difference(F=0.23, P>0.05) was observed in hyperparasitoids quantity trapped by different mixed liquids with sugar, wine and vinegar. There were significant differences among different colors(F=25.71, P<0.05), yellow had the best effects and trapped 925 hyperparasitoids, which made up to 51.13% of the total. White also presented strong trapping effects and ranked the second. White cups trapped 373 hyperparasitoids, occupying 20.62%. 【Conclusion】Yellow cups contained mixed liquid with sugar, wine and vinegar can be used for trapping hyperparasitoids, which can improve the efficiency for mass rearing of A. gifuensis.
