摘  要:
以橘小实蝇为研究对象,研究蛋白饵剂对不同日龄、不同释放密度不育雄虫的引诱作用,以及施用蛋白饵剂后不同时间、添加多杀菌素对不育雄虫的引诱效果。结果表明,蛋白饵剂对不育雄虫的引诱率明显低于同日龄正常雄虫,5日龄时最高,分别为36.24%和48.93%,且随着日龄的增加,引诱率会不同程度下降。不育雄虫释放密度对引诱率无显著影响,0.25~1.00头/m2的释放密度下引诱率为33%~58%。不论是挂瓶法引诱,还是混入0.02%多杀菌素后点喷,蛋白饵剂对不育雄虫的引诱效果均随蛋白饵剂施用天数的增加而逐渐下降,挂瓶法前2d引诱的不育雄虫数量占总引诱数量的65%,添加多杀菌素法该比例则达到80%,5d后这2种方法不再有引诱效果。残留的多杀菌素对不育雄虫无触杀作用。

摘  要:
The attractant rate of protein bait to Bactrocera dorsalis(Hendel) sterile males at different ages and release densities,and the temporal changes in attractant rate of the bait with or without spinosad were studied.The results showed that the bait had a lower attractant rate to sterile males than to wild males,and the attractant rate decreased with age and reached a maximum level rate at the age of 5d old,which were 36.24% and 48.93%,respectively.The density of released sterile males had no significant effect on attractant rate,which reached 33% ~ 58% at the releasing density of 0.25 ~ 1.00 males /m2.The attractant rates to sterile males decreased with the duration after bait application both with 0.02% spinosad(applied by spraying) and without spinosad(applied by hanging bottles),which were 80% and 65% of total sterile males,respectively.The attractant effcet disappeared 5d later and spinosad residues had no contacting action to sterile males.
