Ocorrência de Bactrocera carambolae Drew e Hancock (DIPTERA: TEPHRITIDAE) em Mangifera Indica L (ANACARDIACEAE) no município de Mazagão/Amapá

Abstract

Fruit flies are the most important pests in the world fruit crop due to the great damage they cause to fruits, the high cost of their control and the major obstacle to the free movement of fresh fruits in world trade. Due to phytosanitary barriers, the presence of fruit fly species in areas used for fruit growing has limited Brazilian fresh fruit exports and a better use of the country's potential for this activity. Survey of host species of fruit flies is important in order to monitor the infesting species, especially in mango fruits that show a potential host for star fruit fly, a species with quarantine pest status. The objective of this research was to verify the fruit fly infestation in fruits of Mango (Mangifera indica) from the municipality of Mazagão Amapá. The research was carried out in April and May 2018, in urban and rural areas of Mazagão, from where mango fruits were collected. The fruits obtained were grouped in transparent trays and closed with organza tissue. The trays contained a thin layer of sterile sand that served as a substrate for pupation. Every five days the sand was examined and the Tephritidae pupae were collected with spatulas and transferred to clear plastic vials (8 cm in diameter), with a hollow lid and covered with organza, containing a thin layer of moistened vermiculite. your inside. The emerged insects were sacrificed and transferred to properly labeled 70% ethanol glass vials. Twelve samples of mango fruits were collected, totaling 178 fruits (36.87 Kg), from which 553 pupae were obtained from which 258 adults of the star fruit (Bactrocera carabolae) (120 females and 138 males) emerged. The B. carambolae infestation rate was considered low when compared to the infestation rates of other Tephritidae species. In this plant species, the emergence percentage of adults was 46.65%. The hose has proved to be an alternative host of B. carambolae, serving as a natural repository that requires attention from pest control and eradication agencies
