Drosophila suzukii Matsumura and Zaprionus indianus Gupta (Diptera: Drosophilidae) are invasive pests affecting fig crops in Mexico. Monitoring the density of fruit fly populations plays an important role in deciding pest management strategies. In fruit and vegetable production, food baits and traps are commonly used to monitor and control these pests. However, many local fig farmers have limited access to advanced technologies and are constantly seeking affordable and effective solutions to improve their crop yield and income. In this study, we tested three different trap designs (two commercially available and one handmade from plastic) and 3 food baits to capture adults of D. suzukii and Z. indianus. 2 trials were conducted in local fig orchards during different periods: November-December 2018 and July-August 2019. The handmade plastic traps, when baited with commercial attractants, performed similarly to the commercially produced traps for both fruit fly species in both trials. The paper also discusses the impact of the trap design on its effectiveness in attracting and capturing the fruit flies. The study region is known for its high population density of D. suzukii and Z. indianus.
