Abstract
The study aim was to determine the most suitable trap-attractant combination for monitoring of Anastrepha complex in this fruit tree. The trial was carried out in a commercial orange orchard, variety "Valencia" variety, in Morelos state, during two periods (October-November / 2020 and (January-February / 2021), a total 12 weeks. Eight treatments were used, with two combinations (traps-attractants), plus two controls. The number of adults captured and the proportion by sex of females: males / treatments and the species present were analyzed. As results, three species of Anastrepha were identified: A. ludens, A. obliqua, A. striata, reporting as more abundant to A. ludens. Females had a higher prevalence than males, being A. ludens, that showed the highest proportion, (3:1) and (1.8:1) in both periods. While, in A. obliqua, it was the reverse (1:2) in first period and (0,69:1) in second period. The best trap-attractant combination corresponded to (PET-Cera Trap®) and (Multilure®-Cera Trap®) treatment, which reached the highest number of trapped flies and highest index (MTD), with 0,2292 and 0,2024 respectively. The climatic variables analyzed, mean temperature had a positive correlation on the insect species in both periods, with a greater influence on A. ludens, which showed better adaptation to the local conditions in orange crop.
