A.  aUse of preservatives in vegetable protein-based food attractants for monitoring anastrepha fraterculus (DipterabTephritidae) in peach orchards.h[electronic resource]  c2021  aStudies have demonstrated that the addition of preservatives mixed with food attractants have provided a more expressiveattractiveness for fruit fly adults. The objective of the study was to evaluate the capture ofAnastrepha fraterculus(Wiedemann, 1830) adults when the addition of borax and/or benzalkonium chloride preservative in BioAnastrephaTMandIsca Samaritá TradicionalTMfood attractants compared to CeraTrapTM(control, no preservatives added) in peach orchards. Aswell as, verifying the effect over non-target insects. BioAnastrephaTM, Isca Samaritá TradicionalTMand CeraTrapTMattractantsenabled the capture ofA. fraterculusadults when used by themselves in McPhail traps. However, by adding borax andbenzalkonium chloride, BioAnastrephaTMand Isca Samaritá TradicionalTMfood attractants significantly increased the numberof adults captured. Additionally, the number ofA. fraterculusadults captured by BioAnastrephaTMattractant + borax was similarto CeraTrapTMattractant over time. Regarding non-target insects, the highest percentages of subjects captured belong to theColeoptera (4.4 to 11%) and Diptera orders (24.1 to 34.6%) (Drosophilidae family). Nevertheless, insects from the Hymenopteraorder [(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 theA. fraterculustotal. Addingborax and benzalkonium chloride to BioAnastrephaTMand Isca Samaritá TradicionalTMfood attractants potentialize the effect ofA. fraterculuscapture in monitoring traps. Also, adding preservatives made attractants more durable, consequently, the need toreplace attractants was not as frequent  aFruit flies  aMonitoring  aTraps  aFood attractants1 aPIOVESAN, B.1 aUENO, B.1 aBERNARDI, D.1 aBOTTON, M.1 aNAVA, D.
