EFFECT OF METEOROLOGICAL FACTORS ON THE NOCTURNAL ACTIVITIES OF BLOOD-SUCKING MIDGES / 第二军医大学学报

ABSTRACT

The nocturnal activities of, biting midges, mainly Culicoides nipponensis Toku-naga and C. schultzei (Enderlein) of Shanghai district were observed. Catches were hourly made with an ultraviolet light trap over nights. Using electronic computer and stepwise regression technique, the relationship between the caught number of the midges and meteorological factors was analysed. The primary comparison of 3 types of the mathematical models with a general regression analysis was made. The results obtained are as follows1.Wind is the most important weather factor which affects the activities of both the midges. And the temperature is the second. The suitable weather conditions for their activities are windspeed of
