AbstractField studies in Ontario, Oregon, and California on interspecific attraction and inhibition among the coniferophagous species of Choristoneura (the spruce budworm and its allies) confirmed specific pheromonal differences among the species. Of the three species that are mutually attractive and whose males are attracted by blends of trans- and cis-11-tetradecenal, C. fumiferana, C. biennis, and C. occidentalis, catches of C. fumiferana males in traps baited with C. fumiferana females were significantly reduced by the presence of females from a second group in which it is believed the females produce trans-11-tetradecenyl acetate. Catches of C. occidentalis males by C. occidentalis females were not affected in this way. F1 hybrids and backcrosses between an aldehyde-producing species and an acetate-producing species produced females that were attractive to males of one or other of the parent species, although some females were not attractive to either. Individual females never attracted males of both parent species, and of those that were attractive, more were attractive to males of the aldehyde species than to males of the acetate species. The results suggest sex-controlled inheritance and expression.

Interpretation Of Results

AbstractField tests of (E)-11-tetradecenal and (E)-11-tetradecenyl acetate, the respective sex attractants for western spruce budworm, Choristoneura occidentalis Freeman and the Modoc budworm, C. viridis Freeman, revealed that these compounds attract several other forest Lepidoptera. The acetate attracted a total of 14 species representing seven families, and the aldehyde accounted for nine species representing four families. This interspecific attraction could influence budworm trapping efficiency and interpretation of results, because of the abundance of other responding species and the fact that two of the species resemble Choristoneura adults in appearance.

Tetradecenyl Acetate

AbstractWind tunnel experiments confirmed the optimum blend of the two major components of the sex pheromone of the spruce bud worm Choristoneura fumiferana (Clem.), (E)- and (Z)-11-tetradecenal, to be close to a ratio of 95(E):5(Z). The addition of two minor components, (E)-11-tetradecenyl acetate and the saturated tetradecanal, previously identified in the effluvia of calling virgin females, showed that the acetate alone reduced the level of some responses, while the addition of tetradecanal to the acetate:aldehyde blend restored response to previous levels. Addition of tetradecanal alone showed only minor effects on responses. Males responding to calling females showed higher levels of response and sustained flight longer than did males responding to the four-component blend, and this fact suggests that the blend is incomplete.

Main Component

In electroantennographic studies on Tortrix viridana ma­les, (E)-11-tridecenyl acetate displayed the highest activity of all straight-chain alkenyl acetates. However, evidence obtained by gas chromatography coupled to an electroan­tennographic detector or a mass spectrometer indicated that the ubiquitous pheromone compound (Z)-11-tetrade- cenyl acetate is the main component in the T. viridana fe­male secretion. This compound and both (Z)- and (E)-11- tridecenyl acetate were found to be attractants for T. viridana males in the field. (Z)-9- and (E)-11-tetradecenyl acetate were not attractive and reduced male catches when added to either (Z)-11-tetradecenyl acetate or (E)-11-tridecenyl acetate. No evidence for synergistic effects was obtained.

Abstract Evidence obtained by glass capillary gas chromatography coupled to an electroantennographic detector or a mass spectrometer confirmed that Z-11-hexadecenyl acetate is the major component in the pheromone gland washes of calling Mamestra brassicae female moths. Three other components were identified, tetradecanyl acetate, hexadecanyl acetate and E-11-hexadecenyl acetate; but none of these had obvious synergistic effects in attracting males in field tests. The attraction of males to Z -11-hexadecenyl acetate was inhibited by 0.1% Z -11-hexadecenol or 1% Z-9- tetradecenyl acetate.
