Studies have demonstrated that the addition of preservatives mixed with food attractants have provided a more expressive attractiveness for fruit fly adults. The objective of the study was to evaluate the capture of Anastrepha fraterculus (Wiedemann, 1830) adults when the addition of borax and/or benzalkonium chloride preservative in BioAnastrepha TM and Isca Samaritá Tradicional TM food attractants compared to CeraTrap TM (control, no preservatives added) in peach orchards. As well as, verifying the effect over non-target insects. BioAnastrepha TM , Isca Samaritá Tradicional TM and CeraTrap TM attractants enabled the capture of A. fraterculus adults when used by themselves in McPhail traps. However, by adding borax and benzalkonium chloride, BioAnastrepha TM and Isca Samaritá Tradicional TM food attractants significantly increased the number of adults captured. Additionally, the number of A. fraterculus adults captured by BioAnastrepha TM attractant + borax was similar to CeraTrap TM attractant over time. Regarding non-target insects, the highest percentages of subjects captured belong to the Coleoptera (4.4 to 11%) and Diptera orders (24.1 to 34.6%) (Drosophilidae family). Nevertheless, insects from the Hymenoptera order [(Formicidae (0.14 to 0.96%), Vespidae (0.02 to 0.3%), and Apidae (0.04 to 0.9%)] families. Neuroptera (0.02 to 0.98%) and Lepidoptera (0.09 to 0.7%) were also captured, although those amounted to less than 1% of the A. fraterculus total. Adding borax and benzalkonium chloride to BioAnastrepha TM and Isca Samaritá Tradicional TM food attractants potentialize the effect of A. fraterculus capture in monitoring traps. Also, adding preservatives made attractants more durable, consequently, the need to replace attractants was not as frequent.
