摘要
桔小实蝇[Bactroceradorsalis(Hendel)]是危害热带、亚热带水果和花芽的重要检疫性害虫之一。本研究对湛江地区芒果、杨桃、番荔枝、番石榴桔小实蝇成虫的年发生动态进行了调查。结果表明,桔小实蝇成虫在上述4种水果上拥有1￣2个发生高峰期,发生高峰期基本上与果实成熟期相吻合。杨桃果园桔小实蝇诱捕量明显高于其它3个果园桔小实蝇诱捕量。室内药效试验结果表明,40%辛硫磷乳油、48%乐斯本乳油对芒果桔小实蝇幼虫的防治效果为100%。而田间药效试验结果表明,1.8%阿维菌素、30%敌百虫和2.5%功夫对番荔枝桔小实蝇的防治效果分别为91.47%,88.74%和13.28%。甲基丁香酚+敌敌畏对桔小实蝇雄性成虫具有良好的诱杀效果,水解植物蛋白对桔小实蝇雌性成虫具有一定的诱杀作用。
Bactrocera dorsalis （Hendel） has become an important pest attacking tropical fruits and floral buds in South China in recent years. An attempt was made to study the occurrence and control of this pest infesting four tropical fruits ： mango （Mangifera indca）, carambola （Averrhoa carambola L）, custard apple （Annona squamosa） and Guava （Psidium guajava）. The highest number of adults of B. dorsalis was found once or twice, which generally coincided with the fruit mature stage. The population of B. dorsalis （Hendel） was observed to be obviously higher in the Carambola orchard than in the other three orchards. Phoxim and chlorpyrifos were found effective to control the larvae of B. dorsalis （Hendel）, and the abamectin, trichlorphon, lambda-cyhalothrin were effective to control the adults of B. dorsalis. Sex attractants were important in the integrated population management of B. dorsalis.
