FRUIT FLIES AND THEIR PARASITOIDS IN THE FRUIT GROWING REGION OF LIVRAMENTO DE NOSSA SENHORA, BAHIA, WITH RECORDS OF UNPRECEDENTED INTERACTIONS

ABSTRACT Several fruit fly species (Diptera: Tephritidae and Lonchaeidae) assume the status of primary pests in fruit trees grown in Brazil, causing direct production losses. The aims of the study were to know aspects of diversity of fruit flies and their parasitoids in the fruit growing region of Livramento de Nossa Senhora, Bahia. Fruit samples were collected from 19 plant species during November/2011 and June/2014. Infestation rates were calculated in pupae.kg-1 of fruit and pupae.fruit-1. The results indicate the occurrence of Anastrepha obliqua (Macquart), Ceratitis capitata (Wiedemann) and Neosilba pendula (Bezzi). Plant species Anacardium occidentale, Averrhoa carambola, Carica papaya, Eugenia uniflora, Malpighia emarginata, Mangifera indica var. “Haden”, “Rosa” and “Tommy Atkins”, Opuntia ficus indica, Pereskia bahiensis, Psidium guajava, Spondias lutea, Spondias purpurea and Spondias tuberosa are hosts of fruit flies in the region. Unprecedented bitrophic relationships between P. bahiensis and C. capitata and Anastrepha sp. and between Opuntia ficus indica and C. capitata and A. obliqua were recorded. Unprecedented tritrophic relationship for the state of Bahia Averrhoa carambola and C. capitata and parasitoid of the Pteromalidae Family were also recorded. Tritrophic associations between M. indica var. “Tommy Atkins” and S. purpurea and A. obliqua and Doryctobracon areolatus; and between S. purpurea and A. obliqua and Utetes anastrephae were observed.
