Evaluation of fermented lures for monitoring Tephritid flies in mangoes cultivation (Manguifera indica) Chongón-Province of Guayas.

The research was conducted in an open field at the Villaforest farm, Chongón parish, Guayas Province. The genus Anastrepha spp. is one of the pests considered quarantine for other countries worldwide and is the most prevalent in South America. This research aimed to find an effective low-cost lure that helps reduce fruit fly populations. The experimental design used was a randomized complete block (RCBD), and means comparisons were made with the non-parametric Friedman test. The treatments were evaluated from the blossom to fruiting stages of mangoes. The control (T5) hydrolyzed protein obtained the highest captures with 524 specimens, (T3) Torula with 261 specimens, and (T1) Em-yeast-molasses-Ammonium Sulfate with 239 specimens. The most prevalent genera and species were Anastrepha fraterculus, Anastrepha obliqua, and Anastrepha serpentina. The most economical cost between the treatments was (T1) Em-yeast-molasses- Ammonium Sulfate. In the mean comparisons during the first and second month of the trial, (T3) Torula and (T5) hydrolyzed protein showed no significant differences in terms of FTD (fly/trap/day), and in the third month during the mango fruiting period, (T5) hydrolyzed protein achieved the best results followed by (T1) Em-yeast-molasses-Ammonium Sulfate, and then (T3) Torula.
