Visual inspection and regular sampling are the best monitoring tools for determining pest presence and susceptibility to control. However, cost and time may mean this is not feasible. As a result, degree-day models and plant phenological indicators (biological events in plants that are determined, in some degree, by climatic conditions) have been proposed as alternative methods to predict insect and mite development. These methods have been proven to be excellent predictors for an array of ornamental and turf pests. Click here to learn more about degree-day monitoring.
