Fruit fly (Diptera: Tephritidae) associated with mango tree in the eastern Seridó region of Paraíba, Brazil

Abstract

The fruit fly responsible for causing serious damage to the culture (Mangifera indica L. – Anacardiaceae) and socioeconomic damage. Thus, the objective of this work was to report the species of fruit fly, their faunal indices and populational fluctuation in mango trees varieties Sword and "Maranhão" mangos in the Seridó Oriental region of the state of Paraíba. The work was developed in a mango tree orchard with the varieties of Sword and "Maranhão" mango, not technified, in the Várzea Verde community, municipality of Frei Martinho, Paraíba, Brazil. The fruit fly were collected with the aid of McPhail traps. Hydrolyzed protein was used as food bait, 5% diluted in 500 ml solution. The identification of tephritids was held at the Entomology Laboratory of the Federal Rural University of Semi-Arid (UFERSA) in the municipality of Mossoró-RN. The following fauna indexes were calculated (dominance, abundance, frequency and constancy). For monitoring the adult flies were calculated Fly/Trap/Day indices, correlating with climatic conditions, temperature and precipitation. There were 1,364 specimens captured of fruit fly, represented by six species Anastrepha obliqua (Macquart, 1835), A. dissimilis Stone, 1942, A. sororcula Zucchi, 1979, A. zenildae Zucchi, 1979, A. distincta Greene, 1934 e Ceratitis capitata (Wiedemann, 1824), the largest number of species were from genus Anastrepha. Abiotic factors, temperature, and precipitation influenced negatively on fruit fly of the mango trees in the fruiting period.
