The Abundance of Fruit Flies (Bactrocera Spp.) On Some Varieties of Mango from Three Selling Sources

ABSTRACT The fruit fly is one of the detrimental pests to mango production in Indonesia. Information about fruit fly species in the mango production areas is pivotal for analyzing pest risk assessment, developing appropriate standards for plant quarantine treatment, and managing its control programs. This study aims to analyze the fruit fly abundance and composition among three mango cultivars (“Gedong Gincu,” “Cengkir” and “Arumanis”) in Indramayu, Majalengka and Sumedang Regencies, Indonesia. The mangoes were selected randomly by hand collecting from trees, middlemen and traditional vendors. All collected fruits were transferred to the laboratory. The fruits were retained in the cages until the fruit fly imagoes emerged. The results showed that Bactrocera dorsalis (Hendel), Bactrocera carambolae Drew & Hancock, and an interspecific hybrid of both species were found on mangoes from all study sites. The Bactrocera umbrosa (Fabricius) was merely found on mangoes in Sumedang Regency. The B. dorsalis was the dominant species in all mango cultivars. The nutritional content of mangoes did not correlate with the abundance, species diversity and weight of fruit fly pupae.
