Collections of mosquitoes by means of a scoop were carried out in the Kampinos Forest near Warsaw. The author aimed at detertnining the course taken by the variations in the numbers of mosquitoes in the forest ground vegetation, in the light of the 24-hour cycle of activity exhibited by the mosquitoes. Investigation revealed that during the period of ilhe daytime decrease in the activity af the mosquitoes, a certain constant high quantitative level of mosquitoes was maintained in the forest ground vegetation. (fig. l and 2). This level fell considerably during the evening flights of mosquitoes, then reached and remained near zero level throughout the night. During the morning increase in the activity of the mosquitoes at the level of the undergrowtth, scoop collecions revealed a renewed increase in the number caught, which after the mosquitos had attained their minimum daytime activity, again reached the high level observed during the day (diagram 2 and 3). This would seem to indicate that the minimum night activities of the mosquitoes, observed at forest undergrowth is caused by the dispersion flights of the insects to areas inaccessible to them during the day on account of the microclimatic conditions prevailing there.
