Thus, the hydrolyzed protein CeraTrap™ showed the highest efficacy for fruit fly monitoring in the citrus orchard. fraterculus in amounts above the control level for 28, 20, 11, and 6% of the study period, respectively. fraterculus in amounts above the economic threshold (0.5 FTD) over 73% of the study period, whereas Torula™, BioAnastrepha, corn syrup, and grape juice lured A. Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae) was the species with the greatest mean number of fruit fly adults per trap per day (FTD), with 7.8, 2.8, 2.6, 1.7, and 0.9 FTD for the food lures CeraTrap™, Torula™, BioAnastrepha, corn syrup, and grape juice, respectively. Traps were rotated weekly to prevent any bias in treatment location. McPhail traps were baited with 300 mL of each food lure, and the traps were placed 10 m apart at the edge of the orchard. The lures were replaced weekly with the exception of CeraTrap™, which was replaced every 45 d. Food lures included: 1) CeraTrap™ (undiluted), 2) Torula™ (6 tablets of 3 g/L), 3) BioAnastrepha (5%), 4) 10% corn syrup, and 5) 25% red grape juice (control). ![]() The aim of the current study was to evaluate the effectiveness of 5 food lures for fruit fly monitoring in citrus orchards in the municipality of Pinto Bandeira, Rio Grande do Sul State, Brazil, from Nov 2012 to Oct 2013.
