橘小实蝇不育雄虫田间释放效果

Effect of releasing sterile male of oriental fruit fly in the field

观察研究了橘小实蝇不育雄虫经辐射后田间释放的效果.结果表明,橘小实蝇雄虫经辐射后释放,第6天最远扩散距离可达207.89 m,田间最长存活期为15 d,与田间野生雌性橘小实蝇交配后,其卵不育率为91.15%,而对照区卵不育率仅为21.02%,达到了较好的释放效果.

Effect of releasing sterile male of oriental fruit fly Bactrocera dorsalis（Hendel） in the field was discussed.The result showed that the sterile male of oriental fruit fly could fly 250.00 m away from the releasing point 6 days later and the longest longevity was 15 days in the field;sterile rate was 91.15%±1.44%.
