Conditions governing the distribution of insects in the free atmosphere. IV. Distributive processes of economic significance



Canadian Ent 77(4): 69-74



The distribution of insects by wind in the atmosphere occurs within the lower layers. Such distribution may be over a short or long range. Convection may carry insects to high altitudes, but distributes them over relatively short ranges at the surface . To establish a new insect colony of economic significance a distributive process must combine the properties of steadiness in direction and lengthy duration. In this regard, long-distance distribution by wind usually may be neglected since it is an unsteady phenomenon, only occasionally delivering a few individuals of a given species to a suitable habitat. Short-range, high or low-altitude processes produced by local topography are of most significance economically. These processes are more or less fixed in direction, and recurrent at short intervals. Thus they may be responsible for the infiltration of a species in a relatively short time. It should be possible for entomologists to utilize the presence of such weather factors in planning the control of pest-species. It may or may not be necessary to call in local meteorologists for weather information.
