ABSTRACT
The South American fruit fly, Anastrepha fraterculus, is a serious pest of fruits in all of Latin America. It has been reported from crops such as orange, mango, peach and guava. Volatile compounds produced by Anastrepha species have been identified only from A. ludens and A. suspensa. Pheromone components of male flies of these two species were obtained from whole body extracts, abdominal extracts and by aeration. Beneath the lateral abdominal pouches of many tephritids, there are two male-specific glands, the pleural glands and the male dimorphic salivary glands. Male salivary glands of several Anastrepha species, including A. fraterculus, arise from a common duct in the head which bifurcates into two lateral tubes that extend down each side of the abdomen and end as a large ball of coiled tubules. Salivary glands of male flies were attractive and acted as an arrestant for mature virgin females. Male salivary glands were highly attractive in laboratory bioassays to virgin mature females.
