Males mating strategy involves claiming a territory and defending it from other males through sounds and physical actions. [4], Most species in the Anastrepha genus including A. ludens have a distinctive yellow and brown coloration of the body and wings. Using release-recapture technique, researchers observed flies moving back and forth between the two habitat areas. Allow authorized agricultural workers access to property to install and inspect insect-monitoring traps. The present study investigates whether ageing influences the mating frequency of mass‐reared fertile and sterile Mexican fruit flies Anastrepha ludens (Loew). The ability of males of different ages to inhibit female remating is also determined, and the growth of male reproductive organs is measured as they age.
