Physiological time-driven model for predicting first generation of the hairy chinch bug (Hemiptera: Lygaeidae) on turfgrass in Ohio






Journal of Economic Entomology 85(3): 821-829

Physiological time-driven model for predicting first generation of the hairy chinch bug (Hemiptera: Lygaeidae) on turfgrass in Ohio

Populations of the hairy chinch bug, Blissus leucopterus hirtus Montandon were sampled weekly from April to November in 1978-1980 at four turfgrass sites in Wayne County, Ohio. Two complete generations occurred annually in northeast Ohio. Adults of the first generation were most abundant beginning in late August and overlapped with early second-generation adults. A probit model was used to describe the trajectory of first- and second-generation second-instar hairy chinch bug samples as a function of physiological time (degree-day accumulations with 7 degree C threshold). The fitted model was then applied to validation data taken in a separate study to predict the population trajectory. It predicted first-generation second instars very efficiently. Projections of the second generation were poor. This study contributes to a better understanding of hairy chinch bug population dynamics and should aid in timing of control tactics.
