During 1987-1988 replicated 0.3-ha plots of apple and pear were used to measure the efficacy sex pheromone-mediated mating disruption codling moth, Cydia pomonella (L.). Comparisons fruit injury made between pheromone-treated untreated either with or without releases field-collected moths. In IH87, one moth per tree was released twice during season in two orchards total ranged from 7.0 21.2%. Levels pheromonetreated 1.0-4.0%. 1988, five trees three times no moths plots. Seasonal ranges 1.41-1,65% 0.39-1.21% releases, respectively. Correspondingly, levels 0.09-0.27% 0.05-0.07% 0.05 0.16%, Average emission (E, E)-8,10- dodecadien-l-ol at dusk for a 14-d period after 8.4-40.9 mg/ha h each year. Spatial analysis showed that aggregated movement within limited not influenced by presence pheromone. Our data suggested more occurred on 'Golden Delicious' than 'Red Delicious'.
