Abstract

The population dynamics of the leafhopper Neoaliturus fenestratus (H.-S.) was studied at two temperatures (20 and 25°C) and on a summer host-plant (safflower) and a winter host-plant (Chrysanthemum segetum).

The life-span, reproduction and computed rates of increase were established, and it was found that the leafhopper performed best on safflower at 25°C. Delayed mating induced longer survival in both sexes. C. segetum, the winter host-plant, enabled long maintenance of the insect, although markedly reducing its rate of reproduction. The implication of these findings for the seasonal cycle of the leafhopper is discussed.
