Abstract
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. أظهرت النتائج أن درجة 10 م هي أنسب درجات الحرارة المؤثرة عل نسبة الوفيات في العذارى المعاملة ، تليها درجات 32 ، 20 ثم 26 م . كما أظهرت النتائج زيادة تدريجية في نسبه ا...
