Developmental rate of the squash bug, Anasa tristis (Heteroptera: Coreidae), at constant temperatures
Environmental Entomology 17 (6), 926-929
Abstract: Development of the squash bug, Anasa tristis DeGeer, was observed at 12 constant temperatures between 20.0 and 40.0°C. Times required for development of all life stages at the different temperatures followed the classic 'backwards-j' shape. A nonlinear biophysical model was fit to data representing each individual life stage as well as to several combinations of life stages. Generally a four-parameter model was selected with high-temperature inhibition of development. R² values for the individual models ranged from 0.901 to 0.994. The models indicate that the use of heat-unit accumulation techniques to predict development times is valid within, the linear response range of A. tristis and may be used in the development of management strategies.
