Drosophila suzukii (Matsumura) is an exotic pest of economic importance that affects several soft-skinned fruits in Mexico. Previously, we found that yellow or yellow-green rectangular cards inside a transparent trap baited with attractants improved D. suzukii capture. In this study, we evaluated the influence of rectangular cards with different yellow shades inside a transparent multi-hole trap baited with apple cider vinegar (ACV) on D. suzukii capture in the field. Second, we tested whether ACV-baited traps with cards of other geometric shapes affected D. suzukii catches compared to traps with rectangular cards. Third, we evaluated the effects of commercial lures combined with a more efficient visual stimulus from previous experiments on trapping D. suzukii flies. We found that ACV-baited traps plus a yellow-shaded rectangle card with 67% reflectance at a 549.74 nm dominant wavelength captured more flies than ACV-baited traps with yellow rectangle cards with a higher reflectance. Overall, ACV-baited traps with rectangles and squares caught more flies than did ACV-baited traps without visual stimuli. The traps baited with SuzukiiLURE-Max, ACV and Z-Kinol plus yellow rectangles caught 57, 70 and 101% more flies, respectively, than the traps baited with the lure but without a visual stimulus.

视觉刺激亮度影响诱饵诱捕器捕获果蝇铃木松村（双翅目：果蝇科）的效率

铃木果蝇（松村）是一种具有经济重要性的外来害虫，影响墨西哥的几种软皮水果。此前，我们发现透明陷阱内的黄色或黄绿色矩形卡片在用引诱剂诱饵后效果得到改善D。铃木井捕获。在这项研究中，我们评估了透明多孔陷阱内不同黄色色调的矩形卡片对苹果醋 (ACV) 诱饵的影响。D。铃木井野外捕捉。其次，我们测试了带有其他几何形状卡片的 ACV 诱饵陷阱是否受到影响D。铃木井与矩形卡片的陷阱相比。第三，我们评估了商业诱饵与之前诱捕实验中更有效的视觉刺激相结合的效果D。铃木井苍蝇。我们发现，以 ACV 为诱饵的诱捕器加上在 549.74 nm 主波长处反射率为 67% 的黄色阴影矩形卡，比以 ACV 诱饵的诱捕器和具有更高反射率的黄色矩形卡捕获更多的苍蝇。总体而言，带有矩形和正方形的 ACV 诱饵陷阱比没有视觉刺激的 ACV 诱饵陷阱捕获更多的苍蝇。与使用诱饵但没有视觉刺激的陷阱相比，使用 SuzukiiLURE-Max、ACV 和 Z-Kin​​ol 加上黄色矩形作为诱饵的陷阱分别捕获的苍蝇多了 57%、70% 和 101%。
