We investigated the attractiveness of grapefruit oil to the Mexican fruit fly. Only high concentrations were attractive in laboratory wind-tunnel bioassays. Attraction of flies to grapefruit oil was not enhanced if they had previous experience with grapefruit. In citrus orchard experiments, undiluted grapefruit oil attracted Mexican fruit flies and enhanced attraction to traps baited with a synthetic food-odor lure emitting ammonia and other nitrogenous chemicals. This is the first demonstration of host fruit odor increasing attraction to another type of attractive blend in Mexican fruit fly. These results indicate differences in the way the flies respond to undiluted grapefruit oil compared with previously tested fruit odors.
我们研究了葡萄柚油对墨西哥果蝇的吸引力。在实验室风洞生物测定中，只有高浓度的葡萄柚油具有吸引力。如果果蝇此前接触过葡萄柚，其对葡萄柚油的吸引力并不会增强。在柑橘园实验中，未稀释的葡萄柚油吸引了墨西哥果蝇，并增强了果蝇对用散发氨和其他含氮化学物质的合成食物气味诱饵诱捕器的吸引力。这是首次证明寄主果实气味会增加墨西哥果蝇对另一种有吸引力混合物的吸引力。这些结果表明，与之前测试的果实气味相比，果蝇对未稀释葡萄柚油的反应方式存在差异。
