THE INTRODUCTION AND COLONIZATION IN PUERTO RICO OF BENEFICIAL INSECTS PARASITIC ON WEST INDIAN FRUITFLIES

Abstract

West Indian fruitflies are well-known pests in Puerto Rico. Two species of West Indian fruitnies (Anastrepha momhinpraeoptans Sein and A. suspensa (Loew)) are well known in Puerto Rico. The frequency of their occurrence in the fruits of mango (Mangifera indica L.), particularly in many of the introduced varieties, in guava (Psidium guajava L.), and in jobos (Spondias spp.) may be readily noted throughout the island. In addition A. suspensa attacks orainge and grapefruit (Citrus spp.).
