    Notes: Abstract (E)-11,13-Tetradecadienal (E11,13–14:Ald) is the major sex pheromone component of the eastern blackheaded budworm (EBB),Acleris variana (Fern.). The compound was identified in female pheromone gland extracts by coupled gas chromatographic-electroantennographic detection (GC-EAD), coupled GC-mass spectrometry in selected ion monitoring mode, and retention index calculations of candidate pheromone components.E11,13–14:Ald alone as trap bait was very attractive to male EBB. Addition of the corresponding diene alcohol or acetate or both did not enhance attraction. (Z)-11,13-Tetradecadienal in binary combination with (E)-11,13–14:Ald neither enhanced nor reduced trap catches. Increasing the amounts of pheromone from 0.01 to 10 µg increased trap catches, but increase of pheromone quantity above 100 µg proportionately reduced attraction. Stabilization of slowly polymerizingE11,13–14:Ald and development of a sustained, adequate release rate is required for pheromone-based monitoring of EBB populations.

    Notes: Abstract Spatial and temporal distributions and relative concentrations of the pheromone of the European grape vine moth Lobesia botrana (Lepidoptera: Tortricidae) were measured in mating disruption trials with electroantennograms. Measurements were carried out over several years during the flight season of the two generations of this pest insect. In three consecutive years significantly higher mean relative pheromone concentrations were measured in summer during the flight of the second generation of L. botrana than in spring during the flight of the first generation (P 〈 0.001). The relative pheromone concentrations in 1989 reached a maximum between late July and early August, when the highest mean daily temperatures were registered. In addition to the differences in mean relative pheromone concentrations, the spatial and temporal distributions of the pheromone differed significantly between spring and summer. EAG recordings taken in summer showed high, uniform pheromone concentrations in the treated plots, whereas in spring strong temporal and spatial fluctuations were recorded. In a vineyard defoliated by a hailstorm, the mean relative pheromone concentrations measured in summer were not significantly different from those measured in spring (P 〉 0.05), but were significantly lower than those of a nearby intact vineyard (P 〈 0.001). The results provided additional evidence that foliage is an important parameter determining mean pheromone concentrations and temporal and spatial distribution of pheromone in mating disruption trials.

    Notes: Abstract Synthetic sex pheromone of the pea mothCydia nigricana, (E,E)-8,10-dodecadien-1-yl acetate (E8,E10–12: Ac), was applied in polyethylene dispensers at a rate of 30 g/ha and 600 dispensers/ha in a 0.6-ha pea field. The release rate ofE8,E10–12: Ac was 140 mg/ha/day after six days, and 82 mg/ha/day after 20 days. Aerial concentrations ofE8,E10–12: Ac, as measured by a portable EAG apparatus, ranged from 2 ± 2 to 7 ± 3 ng/m3. The antennal signal was high and rather constant within pea canopy, but was lower and fluctuated strongly above canopy. Initially, 〉99% isomerically pureE8,E10–12: Ac was released, and male moths were attracted to dispensers. After nine days, isomeric blend composition had equilibrated to approx. 92%E8,E10–12: Ac and 8% of the inhibitory isomersE,Z-,Z,E-, andZ8,Z10–12: Ac. Males were then repelled from the pheromone-permeated field. Traps baited with 100 µgE8,E10–12: Ac caught 258 ± 133C. nigricana males/trap in the control, but no males at all in the disruption field.

    Sex Pheromone of Ascogaster quadridentata, a Parasitoid of Cydia pomonella (1999)

    Notes: Abstract Porapak Q volatile extracts of female Ascogaster quadridentata, an egg-larval endoparasitoid of codling moth, Cydia pomonella, bioassayed in Y-tube olfactometers attracted male, but not female, A. quadridentata. Coupled gas chromatographic–electroantennographic detection (GC-EAD) analysis of bioactive extracts revealed three compounds that elicited responses by male A. quadridentata antennae. GC-mass spectra (MS) indicated, and comparative analyses of authentic standards confirmed, that these compounds were (Z,Z)-9,12-octadecadienal, (Z)-9-hexadecenal, and 3,7,11-trimethyl-6E,10-dodecadienal. (Z,Z)-9,12-Octadecadienal alone attracted laboratory-reared male A. quadridentata in Y-tube olfactometer and field-cage bioassays, and attracted feral A. quadridentata in a field experiment. This sex pheromone could be used to help detect populations of A. quadridentata, delineate their distributions, and determine potential sources of parasitoids for capture and release in integrated programs for control of C. pomonella.

    Spatial distribution of pheromone in vineyards treated for mating disruption of the grape vine mothLobesia botrana measured with electroantennograms (1995)

    Notes: Abstract The spatial distribution of the pheromone of the grape vine moth.Lobesia botrana (Lepidoptera: Tortricidae), was measured in vineyards treated for mating disruption by using an electroantennogram technique (EAG). Five hundred dispensers per hectare, each containing 0.1 g of the main component of the sex pheromone (E,Z)-7,9-dodecadienyl acetate (E7,Z9-12: Ac) were evenly distributed in the experimental vineyards. The EAG amplitudes measured in the experimental plots were transformed into relative pheromone concentrations by means of a calibration curve. Mean relative pheromone concentrations in the center of a treated plot reached 2.31 × 10−4 relative units. No significant differences in the mean relative pheromone concentrations were found between replicate plots (P 〉 0.01). The mean relative pheromone concentrations measured within one plot along a transect at 5-m intervals also showed no significant differences between the sites. These results indicate that inside the borders of treated areas the pheromone was evenly distributed. No sites with significantly lower pheromone concentrations, frequently assumed to be the cause for higher trap catches in some areas, were found. However, the mean relative pheromone concentration rapidly declined more than 100-fold outside the border of the treated plot. At 10 m from the treated area, the EAGs showed no significant difference compared to the EAGs recorded in an untreated area. A rapid drop in the mean relative pheromone concentration was also found on a vertical transect through the canopy of the vineyard. Measurements in an untreated control block gave a mean antennal response approximately 1000-fold lower than in a nearby pheromone treated plot. The significance of the variation in the pheromone distribution for the success of the mating-disruption method is discussed.

    Notes: Abstract Synthetic sex pheromone of the pea mothCydia nigricana. (E,E)-8,10-dodecadien-1-yl acetate (E8,E10–12 : Ac), was applied in a 3-ha pea field at a rate of 17 g/ha, in two different dispenser formulations. Aerial concentrations within pea canopy, as determined by a field electroantennogram (EAG) apparatus, were 2 and 3 ng/m3 in the two dispenser treatments. The validity of the EAG measurements was corroborated by sampling of field air, followed by gas chromatographic quantification ofE8,E10–12 : Ac. Males were attracted to fresh dispensers releasingE8,E10–12 : Ac plus less than 2% of the antagonisticE, Z; Z, E; andZ, Z isomers. Two days after placement, the proportion of these isomers had increased to 6%. Males were then no longer attracted to the dispensers, but were observed to fly out of the treated field. Male attraction to calling females was almost entirely suppressed, and attraction to traps baited with synthetic pheromone was significantly reduced. Larval infestation in the pheromone-treated field was 2%, compared to 36% in a control field.
