Extract

The oak leaf shredder, Croesia semipurpurana (Kearfott), has been a particularly persistent pest of red oak, Quercus rubra, in southern Ontario for several years. It is capable of completely defoliating mature trees leading either to increased susceptibility to disease or mortality. In 1980 about 800 ha in southern Ontario required spraying with Orthenem insecticide (Howse and McDowall 1980). The development of a sex pheromone lure for the oak leaf shredder would be valuable for survey purposes, post-insecticidal spray analysis of adult survival in treated plots, and for potential direct control by means of the disruption technique. Recently mixtures of (E)-11-tetradecenal (E11-14:AL) and Z11-14:AL in the ratios of 80:20 to 90:lO were found to be attractive to male moths (Weatherston et al. 1978). A local outbreak of oak leaf shredder in Sault Ste. Marie afforded an opportunity to determine the insect's response to modifications of the aldehyde blend in order to improve the efficiency of pheromone trapping of this species.
