Activity of female Tabanidae (Diptera) in relation to selected meteorological factors in South Carolina

Hourly measurements of meteorological parameters and tabanid activity were made in South Carolina during daylight periods from 10 June to 28 September 1975. Analysis of the collection data indicated that the activity of tabanids attracted to traps baited with carbon dioxide was affected by barometric pressure, temperature, relative humidity, time of day, and cloud cover. A prediction equation involving the most significant variables was developed. A discernible difference in trap catches was noted for different cloud types. Wind and light intensity had no effect on tabanid activity.
