Does marking affect the mating performance of sterile males of Anastrepha ludens (Diptera: Tephritidae)?

Abstract

In fruit flies three methods of marking are commonly used for the evaluation of the sexual performance of adults in field cages. These methods are marking with label, marking with acrylic paint, and marking by dyed food intake. Some of these techniques can have a negative effect on the sexual performance. Our objective here was to determine the marking effect and color on mating performance of sterile males of Anastrepha ludens (Loew) (Diptera: Tephritidae). The results of the study did not indicate significant differences on mating performance between marked and unmarked sterile males. In the evaluation of marking colors, there were also no significant differences on mating behavior. In conclusion, any of the three methods and colors of marking evaluated do not affect the selection choices of wild females and therefore the sexual performance of sterile males of Anastrepha ludens. The advantages and disadvantages of their application are discussed.
