[Impact of different temperatures on development of Anopheles anthropoghagus in Jiangsu Province]

To observe the development and breeding of Anopheles anthropophagus in Jiangsu Province under different temperatures, so as to provide theoretical evidence for malaria epidemiology research and vector control.

Anopheles anthropophagus was maintained under different temperatures of 16, 19, 22, 25, 28 and 31 degrees C in cultivator, and the development of egg stage, larva, pupal stage and reproductive and vegetative cycle were observed. Then the time of entire developmental cycle of Anopheles anthropophagus at different temperatures was calculated.

Anopheles anthropophagus could not complete its entire life cycle under the temperature of 16 degrees C, and it took 30.68, 23.31, 15.46, 13.60 and 12.41 d to finish its life cycle at the temperatures of 19, 22, 25, 28 and 31 degrees C, respectively.

In the temperature range of 16 to 31 degrees C, the developmental cycle of Anopheles anthropophagus in Jiangsu Province will be shortened when the temperature goes up, but whether the result can be extrapolated to other regions still needs to be verified.
