Abstract
  • This publication deals with the development of integrated pest management of insect and mite species that attack pears in southern Oregon. Since about 1900, when the pear industry became firmly established in this area, losses from arthropod pests have been an important and occasionally limiting factor to the continuous production of high-quality fruit. As is true of other agricultural crops, the pest control tactics utilized by pear growers have passed through distinct stages. In southern Oregon, these control stages can be categorized as ( 1) utilization of marginally effec­tive inorganic pesticides combined with labor ­intensive cultural control methods ( ca. 1900-1945), and ( 2) nearly sole reliance upon synthetic organic pesticides applied on a calendar or pre­ventative schedule ( 1945-present).
