SURVEY AND POPULATIONAL DYNAMICS OF PARASITOIDS OF FRUIT FLIES (DIPTERA: TEPHRITIDAE) OCCURING IN GUAVA (PSIDIUM GUAJAVA L.) IN FORTALEZA, CEARÁ, BRAZIL

ABSTRACT This study was aimed to identify the parasitoids associated to fruit-fly species (Diptera: Tephritidae) occurring in an urban guava (Psidium guajava L.) (Myrtaceae) orchard located in Fortaleza, Ceará State, Brazil, as well as to determine the populational dynamics of these organ isms in the ecosystem. Ripe and newly fallen guava fruits, from November 1999 to December 2000 were collected. The parasitoids obtained belong to the families Braconidae, Chalcididae, Figitidae (Eucoilinae), Diapriidae (Diapriinae) and Eulophidae. The most common parasitoids belong to the family Figitidae. The highest occurrences were in January and March 2000.
