The Influence of Oxygen, Partial Vacuum, Temperature, Relative Humidity Combined with Gamma Radiation on the Mosquito, Culex Pipiens Complex L. I. Effect of Exposure to Temperature and Relative Humidity Alone

The results revealed that a temperature of 10°C was the most effective temperature on pupal mortality of Culex pipiens complex L. followed by 32°C then 20 and 26°C. There was a gradual increase in pupal mortality with increasing the time of exposure to temperatures. The pupal mortality increased with decreasing the relative humidity levels at the same time of exposure. Exposure for short time periods did not affect significantly the pupal mortality. Increasing the exposure time increased mortality.
