Potential damage and growth of cucurbit fruit fly on bitter gourd under different temperatures

The aim of this study was to assess the damage and growth of cucurbit fruit fly B. cucurbitae on bitter gourd using 20, 24, 28 and 32°C temperatures with 80% humidity. At different temperatures, the damage potential of B. cucurbitae reared on bitter gourd was observed highest at 24 and 28°C. Different larval stages of cucurbit fruit fly food consumption was highest at 28°C. The highest feeding index of B. cucurbitae larvae was seen at 20°C and the lowest observed at 28°C. The highest growth index of cucurbit fruit fly reared on bitter gourd was observed at 28°C and the lowest at 32°C. The findings of the research indicate that temperature has a substantial impact on the growth patterns, feeding behavior, and damage potential of B. cucurbitae on bitter gourd. Specifically, the study reports that larval development is most favorable at approximately 28°C.
