Accurate information on the species and host spectrum is an important aspect of fruit flies management. The study was conducted in August to November 2018 to evaluate the host range and species diversity of fruit flies in Lembah Seulawah District, Aceh Besar Regency, Aceh Province, Indonesia. Fruit flies were collected from 3 villages in Kemukiman Saree: Suka Damai, Suka Mulia, and Saree Aceh. The insects were collected using the trapping method. The modified Lynfield trap baited with methyl eugenol (ME) was used in the research. This modified Lynfield trap was applied using used mineral bottles. Shannon-Wiener diversity index, evenness index, and dominance were applied to determine the diversity of fruit flies. The results revealed that there were six species of fruit flies that acted as pests in 21 species of host plants belonged to 12 families. They were Bactrocera carambolae, Bactrocera latifrons, Bactrocera limbifera, Bactrocera papayae, Bactrocera umbrosa, and Bactrocera verbascifoliae. B. carambolae was found to be dominant insect pest even though the results indicated that diversity and evenness index of fruit flies species in this district were low.

An important aspect of fruit fly management is accurate information on the species and their host spectrum. Studies were conducted between October 2011 and September 2013 to determine the host range and species diversity of pest fruit flies in the northern savannah ecology of Ghana. Fruit samples from 80 potential host plants (wild and cultivated) were collected and incubated for fly emergence; 65 (81.5%) of the plant species were positive to fruit flies. From records in Africa, 11 plant species were reported to be new hosts to the African invader fly,Bactrocera invadens(Drew, Tsuruta and White, 2005). This study documented the first records ofDacus ciliatus(Loew) andTrirhithrum nigerrimum(Bezzi) in northern Ghana although both species have been previously reported in other parts of the country. Infestation byB. invadenswas higher in the cultivated fruits;Ceratitis cosyradominated in most wild fruits. Cucurbitaceae were mainly infested by three species ofDacusandBactroceracucurbitae, a specialized cucurbit feeder. Among the commercial fruit species, the highest infestations were observed in mango, tomato, sweet pepper and watermelon, whereas marula plum, soursop, tropical almond, sycamore fig, African peach, shea nut, persimmon, icacina and albarillo dominated the wild host flora. The widespread availability of host plants and the incidence of diverse fly species in the ecology call for particular attention to their impact on commercial fruits and the development of sustainable management strategies against these economically important pests in Ghana.
