Six published sampling techniques, and six trapping and three monitoring techiques developed by the author, were tested in a southwestern Quebec insecticide-free apple orchard to determine a reliable trapping and/or monitoring technique for the plum curculio. / Adult captures in intercepting funnels were distributed, in time and space, according to the seasonal development and ecology of this insect. Females were found to oviposit, prior to fruit set, on mature Granny Smith apples attached at major branch junctions in standard McIntosh apple trees. Relationships between oviposition on these "monitoring" apples and "June" drop and harvest damage were found. Plum curculio damage was concentrated near potential over-wintering sites. / A superior Y-tube insect olfactometer was designed and used to test potential attractants for plum curculio. Two fungicides, benomyl and fenarimol, were found to have no effect on plum curculio during its summer soil phase.
