Biology, temperature thresholds, and degree-day requirements for development of the cucumber moth, Diaphania indica, under laboratory conditions.
The cucumber moth, Diaphania indica (Saunders) (Lepidoptera: Pyralidae), is a tropical and sub-tropical cucurbits pest and a key greenhouse pest in the Jiroft region of Iran. In this study, the effect of different temperatures on the development of this pest was investigated on cucumber, Cucumis sativus L. (Cucurbitales: Cucurbitaceae), leaves in a growth chamber at various constant temperatures (20, 25, 30, and 35ºC). The results indicated that the development period from egg to adult death at the decreased with increasing temperature. Mortality was greatest at 35ºC. Based on a linear model, the highest and lowest temperature thresholds were recorded for male insects and pupal stage as 16ºC and 9.04ºC with thermal constants of 100 and 144.92 degree days, respectively.
