Population fluctuation of adult males and pupal radiosensitivity of the melon fly, Zeugodacus cucurbitae (Coq.) (Diptera: Tephritidae)

Abstract

The experiment was conducted to study the population fluctuation of adult males of melon fly, Zeugodacus cucurbitae (Coq.) in different backyard vegetable gardens of Rajshahi University Campus from July 2014 to January 2015 and radiosensitivity of late age pupae to gamma radiation for determining the appropriate sterility dose. On average, the highest (77.19±19) fruit fly population per trap/month was recorded in August and the lowest was (12.29±0.70) in January. From the experimental results, it was observed that temperature, relative humidity and host availability influenced the melon fly population. It was noted that gamma radiation significantly prolonged the pupal duration (p
