The periods of pest and beneficial activity illustrated below are general guidelines based upon both Ontario field experience and pest biology research. The actual period of activity for any given pest will vary significantly from year to year, depending on over-wintering conditions; seasonal temperature accumulation; relative humidity; rainfall; prevailing wind patterns; and other environmental factors.
