The West Indian fruit fly, (Macquart), is the second most important tephritid fruit fly in Mexico, infesting mango, hog plum and guava fruits. To control this pest, the Mexican government has implemented the use of the sterile insect technique (SIT), which involves the mass production, sterilization and release of flies. However, the laboratory males used in SIT are selected to a lesser extent by the wild females during competitiveness tests. The objective of this study was to compare the effects of males fed on fruit fly food enriched with to those in males fed on food alone, assessing male mating competitiveness, capture of females using traps baited with males fed with the enriched diet and sex pheromone components. The results indicated that males fed with the diet enriched with had increased mating competitiveness and captured more females in the field cage tests. However, no difference was observed in the proportion of volatile sex pheromone components identified during the calling of males. The results suggest the value of incorporating bacteria into the mass rearing technique of adults in order to improve the sexual competitiveness of males from the laboratory compared to wild males.
西印度果蝇（Macquart）是墨西哥第二重要的实蝇科果蝇，会侵害芒果、猪李和番石榴果实。为了控制这种害虫，墨西哥政府实施了不育昆虫技术（SIT），该技术包括大规模饲养、绝育和放飞果蝇。然而，在竞争力测试中，用于SIT的实验室雄性果蝇被野生雌性果蝇选择的程度较低。本研究的目的是比较喂食富含[具体物质未给出]的果蝇食物的雄性果蝇与仅喂食食物的雄性果蝇的效果，评估雄性交配竞争力、使用用喂食富含该物质饮食的雄性果蝇和性信息素成分诱捕的陷阱捕获雌性果蝇的情况。结果表明，喂食富含[具体物质未给出]饮食的雄性果蝇在交配竞争力方面有所提高，并且在田间笼养试验中捕获了更多雌性果蝇。然而，在[具体果蝇未明确]雄性果蝇求偶期间鉴定出的挥发性性信息素成分比例上未观察到差异。结果表明，在[具体果蝇未明确]成虫的大规模饲养技术中加入细菌，对于提高实验室雄性果蝇相对于野生雄性果蝇的性竞争力具有价值。
