[Photoperiod-temperature interaction--a new form of seasonal control of growth and development in insects and in particular carabid beetle, Amara communis (coleoptera: carabidae)].

Amara communis larvae are found to develop significantly faster and have higher growth rate at short-day (12 h) as compared to long-day (22 h) photoperiods under all temperatures (16, 18, 20 and 22 degrees C) used. The coefficient of linear regression of larval development rate on temperature was significantly higher at short days than at long days. At that thermal developmental thresholds appeared similar at both photoperiods.
