Abstract:[Objectives]  To determine the effects of different types of sticky glues, food lures and hanging positions of sticky spheres on the capture rate of adult Bactrocera (Tetradacus) minax (Enderlein). [Methods]  The capture rates of three kinds of sticky spheres; green, 7 cm in diameter, yellow, 7 cm in diameter and yellow-green, 14 cm in diameter, were compared. We also compared the number of B. minax adults trapped by using either hot-melt pressure sensitive adhesives (HMPSAs) or liquid sticky glues, and with or without using food lures. Furthermore, we also investigated the effects of five different hanging orientations and two heights. [Results]  More B. minax adults were trapped using HMPSAs than liquid sticky glues, and there was also a significant difference in the number trapped by green vs yellow sticky spheres (P<0.05). The number of B. minax adults trapped by green sticky spheres was decreased by food lures, as well as the percentage of B. minax adults relative to all insects trapped, but the number of non-target insects trapped by green sticky spheres was increased by using food lures. More B. minax adults were trapped by sticky spheres on the north side of orange trees than those oriented to the other points of the compass (P>0.05). Finally, significantly more B. minax adults were trapped by sticky spheres suspended at 3/4 of height of the crowns of trees than those hung at 1/4 height (P<0.05). [Conclusion]  Sticky spheres to trap B. minax should be treated with HMPSAs. Green sticky spheres should not be used in combination with food lures. Best results are achieved by hanging sticky spheres on the north side of orange trees at 3/4 of height of the crown.
