BIODIVERSITY AND POPULATION DISTRIBUTION OF FRUIT FLY (Diptera: Tephritidae) IN DOMESTIC ORCHARDS OF PARAÍBA STATE, BRAZIL
ABSTRACT The objective of this study was to characterize, through faunistic indices, the populations of fruit flies in the Brejo Paraibano microregion and analyze whether these populations are similar to one another. The study was conducted in eight municipalities located in the Agreste Paraibano mesoregion and Brejo Paraibano microregion, Paraíba state, Brazil, where two rural properties of each municipality were selected, georeferenced and identified according to the diversity criterion of fruit species. Each municipality was assumed to have a population of fruit flies with its own characteristics, determined by the faunistic indices of frequency, constancy, dominance, Shannon-Wiener and Margalef diversity indices, as well as evenness. 3.159 specimens of fruit flies were captured, of which 85.57% belonged to the genus Anastrepha and 14.43% to the genus Ceratitis. 11 species of fruit flies were captured in the traps. Anastrepha fraterculus was the most frequent, dominant and constant species, being present in all locations; followed by A. obliqua, A. sororcula and Ceratitis capitata. The studied municipalities have a similarity of 54%, which indicates a high similarity between the areas. Most species captured in the present study occur at low population frequency.
