AbstractFormates analogous to the aldehyde sex pheromones of several species of Lepidoptera have been shown to have biological activity, (E)-9-Dodecen-1-yl formate was therefore tested against male spruce budworm (C. fumiferana) by EAGs and by field trapping experiments designed to test for attraction, inhibition, and disruption. No biological activity was detected.

Trichoid Sensilla

Priesner (1979) reported five types of receptor in the trichoid sensilla on the antennae of male spruce budworm, Choristoneura fumiferana. One responded maximally to (E)-11-tetradecenal (Ell-TDAL), the primary component of the natural sex pheromone (Sanders and Weatherston 1976). Two other receptors showed maximum response to (E)- 11-tetradecen-1-yl acetate (E 11-TDACET) and (E)- 1l-tetradecen- 1-ol (E11-TDOL), respectively, both of which are present in female glands, but neither of which has been found in significant amounts in the emitted pheromone. The other two receptors showed maximum responses to (E)-9-tetradecenal (E9- TDAL) and (E,E)-9, 11-tetradecadienal (E9, E 11-TDDAL), respectively, neither of which has been reported from gland extracts or the emitted pheromone.

AbstractA reinvestigation of the sex pheromone of the eastern spruce bud worm, Choristoneura fumiferana (Clem.), showed that it contains 11-tetradecenal in the ratio 96% trans-: 4% cis-. Field trapping showed the pure trans- compound to be only slightly attractive. Maximum attraction occurred in the range 2% to 5% cis-.

AbstractThe sex pheromone of the female eastern spruce budworm was identified as trans-11-tetradecenal by a combination of electroantennogram techniques, laboratory bioassays, and chemical analysis. Subsequent field trapping showed that this compound is a potent attractant for both male Choristoneura fumiferana (Clem.) and C. occidentalis Free, thus supporting its identification as a sex pheromone of the eastern spruce budworm and suggesting that it is also a major component in the pheromone system of C. occidentalis.

Air Permeation

The disruption of insect mating with sex pheromones by the air permeation technique is a complex problem influenced by a number of variables. Not least among these is the actual atmospheric concentration of pheromone during the course of the experiment. While closely related to the measured release rate from a formulation, the atmospheric concentration should be regarded separately since a number of other factors may intervene, e.g., chemical instability, foliage adsorption, and the differential effects of formulation weathering in the laboratory and the field.The present study was conducted in conjunction with small scale field trials involving an aerially applied hollow fiber formulation of the sex pheromone of the spruce budworm, Choristoneura fumiferanu (Clem.), I1 -tetradecenal (97:3::E:Z). (Hereafter referred to as pheromone.)

AbstractMale and female laboratory reared spruce budworm moths, Choristoneura fumiferana (Clem.), were placed in cages in a conifer forest, and the surrounding air permeated by each of four blends of the E and Z isomers of the sex pheromone (11-tetradecenal) at two concentrations. Mating suppression of 53–83% was found for each blend tested. At one concentration the four suppressions were similar, while at the other only one was significantly different. Electroantennograms (EAGs) were obtained from male moths for each of six E:Z blends at four concentrations. EAGs were similar for most blends at a given concentration, but tended to be larger than at a blend of 0E:100Z.These results were discussed using a current hypothesis on the ability of males to detect sex pheromone in air containing pockets of different isomeric blends.

AbstractRelease rates of synthetic attractant of the spruce budworm, Choristoneura fumiferana (Clem.), from a PVC formulation were determined by weight loss. They varied in direct proportion to the initial concentration of the attractant and also with the size of the pellet. Release rates declined by about 50% over the time intervals of 10–40 days and 40–100 days. Initially they were two to three times lower at 10°C than at 21°C, but were far more constant over time at the lower temperature. A pellet weighing 130 mg containing 42 μg of attractant released an estimated .1–1 μg/day, or 4–40 ng/h, which is close to the rate of emission by a calling female (Silk et al. 1980), and field trapping data showed that a lure this size attracted the same number of males as a calling female.

AbstractTraps baited with a 95:5 blend of E:Z-11-tetradecenal, the sex pheromone of the spruce budworm, Choristoneura fumiferana (Clem.), were deployed throughout several summers in Ontario to determine what other Lepidoptera were captured that might be confused with the male C. fumiferana. Eight other species of Tortricidae were captured with sufficient frequency to suggest that they were attracted to the traps: Choristoneura conflictana Wlk. (the large aspen tortrix), six species of Acleris, and one Gretchena species. Of these, C. conflictana can easily be confused with C. fumiferana. The evidence suggests that male C. conflictana were not attracted by the pheromone, but blundered into the traps. They are very similar morphologically to male C. fumiferana, but can be differentiated with care.

AbstractA simple and inexpensive olfactometer based on that of Gaston and Shorey (1964) is described for bioassaying the sex pheromone of the eastern spruce budworm. The number of males buzzing (rapidly beating their wings while circling on the substrate) after the introduction of the sample into the airstream of the olfactometer was used as measure of response. Males held under continuous illumination showed maximum response when 2 to 3 days old. Under natural lighting males showed a circadian rhythm, with peak response shortly after dark and a minor peak in mid-morning. Since per cent response under continuous illumination exceeded the maximum response under natural lighting, it is recommended that bioassays be carried out with 2- to 3-day-old males held under continuous illumination.
