Abstract:

Biology of fruit fly was examined in MCC Bangladesh field laboratory at Bogra from July to October 2009 as a part of development of the management strategies for cucurbit fruit fly (CFF), Bactrocera cucurbitae (Coquillett) on bitter gourd. Biology of melon fruit fly, B. cucurbitae revealed that eggs laid by female were creamy white, slightly curved, elongated and tapering towards the ends. Surface of egg was sculptured with numerous longitudinal ridges and grooves. On an average, freshly laid eggs measured 0.78 mm in length and 0.16 mm in width; the average length of larva was 8.8 mm and width was 1.52 mm; the average length of pupa was 4.22 mm and width was 1.76 mm; the average length of the adult male was 13.78 mm and width was 7.06 mm, where the average length of the adult female was 15.62 mm and width was 8.86 mm. The mean incubation period of the fruit fly was 6.98 days. The average larval developmental period was 18.66 days. The average pupal period was 21.3 days. The mean duration of adult stage was 27.67 days. The mean duration of egg to adult was 40.34 days.
