AbstractPre-mating behavior of male gypsy moths was investigated in 0.2 ha circular plots containing from 0 to 72 virgin females/plot in untreated areas and in areas treated with an aerial application of 20 g/ha microencapsulated disparlure. Male moths in both treated and untreated plots oriented initially to trees, not directly to females. Mating was disrupted in treated plots but males continued search behavior. No anemotactic behavior was evident in either treated plots or untreated plots with females. In untreated plots, male moths were not caught on sticky panels (panels suspended at 2, 4, and 6 m) higher than pheromone baited traps set at 2 m. In treated plots, equal number of males were caught at all panel heights and in baited traps at 2 m. Previous mating and pheromone exposure histories of males did not affect the response of these males to traps baited with 4–5 mg of disparlure in untreated plots. In a test of the relative attractiveness of a cotton wick and a new laminated bait dispenser in Johnson traps, traps baited with the laminated dispenser had a greater male moth catch/male contact to trap than the traps baited with the cotton wick. Not all males contacting the Johnson trap were caught. A mode of action for disparlure as a disruptive agent in the long range sexual communication system of gypsy moth is proposed.

AbstractA mark–recapture study examined Trypodendron lineatum (Olivier) spring flight dispersal in a coastal forested valley in British Columbia. Pheromone-baited traps were placed throughout the valley in five separate experiments. Recapture patterns of marked beetles were related to weather, topography, vegetative cover, and source of attractants.Wind direction within the forest setting, 350 m from the closest open site, was quite variable with a beetle recapture pattern mat was non-directional. At a forest setting less than 50 m from an open site and road, diurnal up-valley winds resulted in an upwind beetle recapture pattern at 25 m from the release site. Beetles were recaptured at distances as far as 1.9 km downwind and 1 km upwind from the release site. Most beetles were recaptured within 2 h of release at distances up to 50 m. In traps at distances of 350–700 m, similar numbers of beetles were recaptured on the day of release as were recaptured during the following week. At distances greater than 1 km, almost all beetles took longer than 1 day to be recaptured.
