摘要

Despite their relevant contribution to the conservation of tropical ecosystems and crop productivity through pollination, the stingless bees (Apidae: Meliponini) can be considered a group of neglected species in the assessment of pesticides upon nontarget organisms. In this article, we evaluated the effect of aerial sprays of the spinosad-based fruit fly toxic bait GF-120 upon colonies of the stingless bee Scaptotngona mexicana Guerin (Hymenoptera: Apidae), an economically important and abundant species in some landscapes of Mexico, located in mango orchards. Colonies of the honey bee Apis mellifera L. (Hymenoptera: Apidae) were used for comparison. Eight colonies (four of A. mellifera and four of S. mexicana) were moved into each of two mango orchards, one was used as a control, with no insecticide application, and other received five weekly aerial sprays of GF-120 Foraging activity and strength of colonies of both species were measured nine times over the fruiting season, previous, during and after insecticide application. We did not find a significant difference in foraging activity and strength between exposed and control colonies of A. mellifera during the observation period. However, colonies of S. mexicana seemed to be affected by the exposure, as revealed by a reduction in colony strength. However, 1 yr later, with no insecticide applications, the colonies of both species were evaluated and found to be in good conditions Our results showed that weekly aerial sprays of GF-120 are unlikely to generate acute poisoning in both species, even if in acute toxicity tests this product has been found to be highly active.

Meellifera中的四个）被移动到两个芒果果园中的每一个中，用作对照，没有杀虫剂应用，而其他接受GF-120觅食活性的五个每周空中喷雾剂两种物种的菌落强度在结果季节，先前，期间和之后测量了九次杀虫剂应用。在观察期间，我们没有发现露出和控制A. mellifera的暴露和控制菌落之间的觅食活动和强度差异。然而，S. Mexicana的殖民地似乎受到曝光的影响，正如菌落强度的降低所揭示的那样。然而，1年后，没有杀虫剂应用，评估了两种物种的菌落，发现了我们的结果，结果表明，即使在急性中，GF-120的每周空中喷雾也不太可能产生急性中毒毒性测试本产品已被发现非常活跃。
