EMBRYONIC DEVELOPMENT OF AEDES (O.) STICTICUS (DIPTERA: CULICIDAE) IN RELATION TO DIFFERENT CONSTANT TEMPERATURES

Abstract

AbstractEmbryonic development in the mosquito Aedes (O.) sticticus (Meigen) was studied on moist surfaces at five constant temperatures between 5° and 34 °C. Time for complete embryogenesis was 608, 272, 192, 152, and 120 h at 10°, 15°, 20°, 25°, and 30 °C, respectively. Upper and lower temperature thresholds were 33 °C and from 6° to 8 °C, respectively. Embryonic development proceeded normally when eggs were submerged in water at 25° and 30 °C, and no difference in developmental rate was observed between eggs on moist filter paper and those submerged in water.
