Abstract
A program to control the codling moth, Cydia pomonella (L.), Oriental fruit moth, Grapholitha Molesta (Busck), lesser appleworm, G. prunivora (Walsh), redbanded leafroller, Argyrotaeina velutinana (Walker), obliquebanded leafroller, Choristoneura rosaceana (Harris), and threelined leafroller, Pandemis limitat (Robinson), by mass trapping with sex pheromone baited traps was conducted on a non isolated commercial apple orchard where insecticide applications were withheld. Fruit injury by all 6 species continued to increase under high and low densities ot mass trapping. Injury levels of the tortricid complex exceeded levels acceptable in commercial fruit production. Although significant differences in fruit injury were found among high and low densities of mass trapping and control treatments, the differences could be attributed to factors other than the effect of mass trapping with phermone baited traps.
