AbstractMale moths of Choristoneura occidentalis Freeman, C. biennis Freeman, C. fumiferana (Clemens), and C. orae Freeman were caught in pheromone-baited traps. Ten traps were placed at each site, five baited with an aldehyde lure and five with an acetate lure. This procedure permitted separation of species based on the specific chemical lure and also provided specimens for further study of morphological and isozyme differences. The color of the forewings, presence or absence of spicules on the aedeagus, and a specific allozyme frequency were determined on selected specimens where these characteristics were useful in separating species at a particular site. Distributions of all species were more extensive than previously known, sometimes adding hundreds of kilometres to the recorded range. Areas of sympatry were identified and the fidelity and usefulness of characteristics for separating species in areas of overlap were discussed.

AbstractSex attraction studies were carried out to investigate the mate-finding behaviour of invasiveVespula vulgaris(Linnaeus) (Hymenoptera: Vespidae) wasps. Delta traps were baited with live, caged males, and gynes (virgin queens) ofV. vulgaristo determine whether either sex produced a long-range sex attractant. Traps baited with gynes caught 71 males, while the controls and live-male wasp baited traps did not catch gynes. Wind tunnel trials were performed to verify if the signal produced by the gynes was chemical in nature. First,V. vulgarismales were flown to live caged gynes, where more than half of the males tested flew upwind in a zigzagging pattern and made contact with caged gynes. Males were also flown to hexane rinses of gynes and flew upwind in a zigzagging pattern towards the gyne extract, although none made contact with the cotton roll stimulus. The results presented here demonstrate conclusively thatV. vulgarisgynes produce a sex pheromone.

AbstractApple clearwing moth, Synanthedon myopaeformis (Borkhausen) (Lepidoptera: Sesiidae), is an invasive species in Canada and a destructive pest of commercial apple trees in British Columbia. Adult mass trapping is being developed to help organic apple producers manage this pest. We manipulated and measured spectral reflectance from delta traps, unitraps, and bottle traps used to deploy sex pheromone, phenylacetaldehyde, and grape juice mass-trapping baits and compared catches in baited traps having different reflectance properties. Synanthedon myopaeformis did not discriminate among pheromone-baited delta traps painted yellow, green, or white, from those left clear (group 1), nor among those painted purple, blue, red, or black (group 2). Catches by all treatments in group 1 were significantly greater than all in group 2. Catches in pheromone-baited delta traps were positively correlated with their intensity of green wavelength reflectance (500–550 nm). Fluorescent yellow delta traps reflected more green and ultraviolet (300–400 nm) light than standard yellow or green traps but caught significantly fewer moths when baited with pheromone, implying an antagonistic interaction of green versus ultraviolet-sensitive behaviours. Pheromone-baited all-yellow unitraps caught significantly more moths than equivalent all-green, all-white, or all-red unitraps. Catches in pheromone-baited all-yellow unitraps decreased when any component (lid, funnel, or bucket) was replaced with a green one. Changing the intensity or quality of reflectance from funnels had the greatest impact on unitrap catches (82% reduction). Spectral preferences were modulated by odours eliciting different behaviours (mating versus feeding). When baited with the floral feeding odour phenylacetaldehyde, yellow and green delta traps were among the least attractive, whereas black and blue traps were among the most attractive. When baited with grape juice food baits, black bottle traps caught significantly more moths than any other colour except white, and the former are recommended for maximising mass trapping of females while minimising nontarget impacts of juice baits.
