Cage the fly: Walk-in field cages to assess mating compatibility in pest fruit flies

Posted · Add Comment

Fruit flies studies on mating compatibility have been examined to assess the usefulness of walk-in field cages in sexual behavior research within fruit fly species complexes and recognition of taxonomically misplaced flies. As a result, horticultural trade and pest management are to be facilitated. The use of pheromones for the purposes of species differentiation have […]
