FRUIT FLIES (DIPTERA: TEPHRITIDAE) ASSOCIATED TO HOST PLANTS FROM THE ORCHARD ON THE PICI CAMPUS OF THE FEDERAL UNIVERSITY OF CEARÁ, BRAZIL

ABSTRACT

This paper presents a one-year survey of the fruit flies species and their host plants in the Didactic Vegetable Garden of the University of Ceará (CCA/UFC) in Fortaleza, Ceará State, Brazil. Fruit samples were collected biweekly from January 2005 until January 2006 at different heights within the canopies of the host trees and from fruits recently fallen to the ground. Fruit samples were kept individually in sealed plastic containers in order to establish the precise association between the host fruits and fruit-fly species. Two species,Anastrepha. Anastrephazenildae Zucchi andAnastrepha sorocula Zucchi were obtained. These species were exclusively associated with guava (Psidium guajava L.) fruits. Another three male specimens ofAnastrepha were obtained from ciruela (Spondias purpurea L.) fruits. Specimens ofCeratitis capitata (Wied.) were found to be associated with nine host plants: P. guajava., mango Mangifera indica L.,S. purpurea, Java plum Syzygiumcumini(L.), Malabar plum Syzygium jambos (L.), Surinam cherry Eugenia uniflora L., star fruit Averrhoa carambola L., tangerine Citrus reticulata Blanco and Barbados cherry Malpighia glabra L. From January through March, 2005, the highest rate of C. capitata was obtained from guava fruits.
