Fruit fly is one of the serious pest of Citrus. Among 16 species of fruit fly reported in Nepal, 6 species of fruit flies were found in citrus fruits. According to pest surveys done in Dhankuta and Sindhuli, the species found are: Melon fly (Bactrocera cucurbitae), Oriental fruit fly (B. dorsalis), Peach fruit fly (B. zonata), B. tau, B. scutellaris and Dacus longicornis. Chinese fruit fly, B. minax (Enderlein) (Diptera: Tephritidae) has created devastation in the sweet orange orchards in eastern hills of Nepal and the infestation rate have been found up to 100%. Unlike other Bactrocera species, B. minax is univoltine and oligophagous and adult flies becomes active from April to July. The two highly attractive para-pheromones, Cue lure and Methyl Eugenol used for many Bactrocera species are not attractive for this species. For B. minax, food based lure i.e. protein baits are used. Maintaining field sanitation by proper disposal of infested fruits, winter/summer ploughing, visual cue lures such as colored sticky spheres, mass trapping by using para-pheromones and food based lures, foliar insecticidal spray are the pest management strategies adopted in China, Bhutan, Sikkim and Nepal. Area Wide control program has been launched using technologies: monitoring, Great Fruit Fly Bait (Protein Hydrolysate 25%+0.1% Abamectin) developed by Ecoman Biotech, China, trapping and field sanitation in the year 2018 which has proved successful in control of B. minax in the sweet orange orchards of Sindhuli.
