Extract

1. The work here reported was carried out in Bwamba County, Uganda, a district where human yellow fever has recently occurred. It consisted of continuous 24–hour catches of biting mosquitoes in a banana plantation, made simultaneously at ground level, 6 ft., 12 ft. and 18 ft.

2. Aédes (Stegomyia) simpsoni, Theo., the carrier of human yellow fever in Bwamba, was found to be active throughout the day at all these levels.

3. The presence of sylvan mosquitoes in the banana plantation was noted. The nearest forest was ½ mile away.

4. The biting cycle of the strictly diurnal A. simpsoni was studied, and it was found that this species was most active on warm cloudy days. The main factors decreasing its activity appeared to be cold, wind, and direct hot sunshine.
