BACKGROUND 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). RESULTS 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). CONCLUSIONS This study provides fruit growers with an economical and effective method to capture large numbers of C. capitata, suitable to be part of integrated pest management programs for fruit fly control.
