Abstract

Eggs of Taeniopteryx nebulosa (L.) were incubated in the laboratory at constant temperatures between 2°C and 24°C and at field temperatures. A relationship, linear on logarithmic scales, was found between water temperature (T°C) and mean egg incubation period (Y days) for the temperature range 2 to 24°C. The relationship is given by the regression equation: Y=313 T-1.03 (r = 0.998, p < 0.001). Hatching success was low below 4°C and above 20°C. /// Яйца Taeniopteryx nebulosa (L.) инкубировались в лаборатории при постоянных температурах межху 2 и 24°C и при естественных температурах. Установлена линейная зависимость на логарифмической шкале межды температурой воды (T°C) и средней продолжительностью периода инкубации (Y дней) в градиенте температур 2-24°. Зависимость описывается уравнением регрессии: Y=313 T-1,03 (r = 9,998, p < 0,001). Результаг вылупления низок при температуре ниже 4°C и выше 20°.
