Small-scale farmers often take a double hit from pests such as tephritid fruit-flies. The high price of products against fruit-flies, together with the higher risk of reinfestation from neighboring orchards, limits options for control. Therefore, management requires low-cost local products and concerted action. Peach production in central Bolivia is increasingly affected by invasive Ceratitis capitata. To provide locally sustainable techniques that could incentivize area-wide cooperation of growers, we tested efficiency and specificity of low-cost lures and traps compared with commercial lures and traps (Tephritrap).
In the laboratory, the local fermented beverage 'chicha' and baker's yeast were equally or more attractive than commercial lures. Both chicha and baker's yeast trapped more flies in field (average FTD 10.31 and 9.49), whereas commercially hydrolyzed protein lure (4.71) or Torula yeast (6.82). However, many non-target species were caught (57.3% and 53.4%). Of the six PET bottles-based traps used, the T-trap caught a similar number of flies (average FTD 5.55), but fewer beneficial insects (0.16) compared to the Tephritrap (0.92).

小规模农户经常受到实蝇等害虫的双重打击。由于防治实蝇的产品价格较高，且相邻果园再次虫害的风险较高，因此控制方法的选择有限。因此，管理需要低成本的本地产品和协调一致的行动。玻利维亚中部的桃树生产越来越受到入侵性地中海实蝇的影响。为了提供可持续的本地技术，激励种植者进行区域范围的合作，我们测试了低成本诱捕器和诱捕器（Tephritrap）与商业诱捕器和诱捕器相比的效率和特异性。
在实验室中，当地发酵饮料“chicha”和面包酵母与商业诱捕器一样或更具吸引力。chicha 和面包酵母在田间捕获的苍蝇更多（平均 FTD 为 10.31 和 9.49），而商业水解蛋白诱饵（4.71）或假丝酵母（6.82）则不然。然而，许多非目标物种也被捕获（57.3%和 53.4%）。在所使用的六个基于 PET 瓶的诱捕器中，T 型诱捕器捕获的苍蝇数量相似（平均 FTD 为 5.55），但有益昆虫较少（0.16），而 Tephritrap 则较多（0.92）。
本研究为水果种植者提供了一种经济有效的方法来捕获大量的地中海实蝇，适合作为水果蝇综合防治计划的一部分。© 2018 英国化学学会。
