“…For each species, 15 pheromone glands were excised at each hour of the photophase (-3, -2, -1, 0) and the entire scotophase (1, 2, 3, 4, 5, 6, 7, and 8). In the present study, (E)-11-tetradecenal (E11-14:Ald), the major pheromone component released by SBW females (Weatherston et al, 1971;Sanders and Weatherston, 1976;Silk et al, 1980), was consistently produced in higher quantities (1-6 ng/insect) than (E)-11-tetradecenyl acetate (E11-14:Ac) (0.2-0.6 ng/insect) in the pheromone gland. This differs from a previous study (Silk et al, 1980) reporting E11-14:Ac as the major component (30-40 ng/insect) present in the gland of the SBW.…”

The diel periodicity of calling behavior and pheromone production are synchronous in virgin females of both Choristoneura fumiferana and C. rosaceana (Lepidoptera: Tortricidae). Newly emerged females decapitated prior to scotophase produced no or very little pheromone 24 h later. However, injection of PBAN or Br‐SEG homogenates, obtained from donors of the same or the other species, stimulated pheromone production to normal levels. Transection of the ventral nerve cord (VNC) or extirpation of the terminal abdominal ganglion (TAG) did not affect pheromone production in control females. Similarly, injections of PBAN or Br‐SEG homogenates into decapitated females reactivated pheromone production to normal levels, whether or not the VNC was intact or the TAG present. Furthermore, octopamine was not effective in stimulating pheromone production in decapitated females. Taken together, these results indicate that the regulation of pheromone production is not neurally mediated in either Choristoneura species. However, there was no evidence that hemolymph collected from pheromone‐producing females contained pheromonotropic activity. Similarly, isolated glands incubated with PBAN did not produce pheromone. The presence of the bursa copulatrix was required to produce pheromone in both tortricids as production was not restored in decapitated bursa‐less females injected with PBAN or a Br‐SEG homogenate. However, an extract of the bursa copulatrix did not elicit pheromonotropic activity in decapitated females or incubated glands of either species. The bursa copulatrix is only involved in pheromone production of some species of tortricids but our results do not support the current explanation for such interspecific differences. We postulate that the relative importance of a bursa factor may be related to the evolution of different desaturation systems used for pheromone biosynthesis in the Tortricidae. Arch. Insect Biochem.

“…The budworms C. fumiferana, C. occidentalis, and C. pinus pinus were reared on a synthetic diet (McMorran, 1965;Grisdale, 1970). Their ovipositor tips were excised by severing the abdomen just anterior to the pheromone gland during their "calling" period: for C. fumiferana, 2-4 days old, at the onset of scotophase (_+ 1 hr) (Sanders, 1971); for C. pinuspinus, 1-4 days old, 2-4 hr into scotophase (Sanders, 1971); and for C. occidentalis (Silk et al, 1982), 2-4 days old, 1-2 hr prior to scotophase. R chalcites were reared on artificial diet (Shorey and Hale, 1965), and tips of 4-to 6-day-old females were cut 1-3 hr into seotophase (Dunkelblum et al, 1981).…”

“…The method is based on the direct capillary GC-MS-EI analysis of the dimethyl disulfide (DMDS) adducts of fatty acid methyl esters similar to that applied to monounsaturated acetates (Buser et al, 1983). The moth species investigated, for which published information is available on their respective sex pheromone components, were three tortricids from the Choristoneura genus: C. fumiferana (Sanders and Weatherston, 1976;Silk et al, 1980), C. occidentalis (Cory et al, 1982;Silk et al, 1982), and C. pinus pinus (Silk et al, 1985), and one noctuid from the Plusiinae subfamily, Plusia chalcites (Dunkelblum et al, 1981).…”

A rapid analytical procedure for the determination of the position of double bonds in mixtures of monounsaturated fatty acid methyl esters has been developed. The method is based on direct capillary GC-MS-EI analysis of dimethyl disulfide adducts. The procedure was applied to mixtures of monounsaturated fatty esters from pheromone gland extracts of three tortricids from theChoristoneura genus,C. fumiferana, C. occidentalis, andC. pinus pinus, and one noctuid from the Plusiinae subfamily,Plusia chalcites. A correlation was found between the known major pheromone components in the four species with the corresponding fatty acids. Some of the additional fatty acids may be precursors to as yet unidentified minor pheromone components, present in extremely small quantities, in these species.

“…has been shown to comprise of two primary components and possibly two additional (secondary) components; the primary components are Ell-tetradecenal (Ell-14:Ald, Weatherston et al 1971) 1976) while the secondary components are tetradecanal (14:Ald) and E l 1-tetradecen-1-01 acetate (El 1-14:Ac) and are found in the effluvia in the ratio 95:5:2:0.2, respectively (Silk et al 1980). We have examined the effect of these components in the longrange and close range behaviours of the male spruce budworm moth in a sustained-flight wind tunnel and in the field.…”

Can. Ent. 115: 1053-1058 (1983) Laboratory wind tunnel and field observations have demonstrated an important behavioural role of tetradecanal(14:Ald) in the chemical communication system of the spruce budworm, Choristoneura fumiferana (Clemens). A greater numbe; of males initiated upwind flight and continued on to contact the source when 14:Ald was present than with 9515 EIZ1 1-tetradecenal (EIZ11-14:Ald) alone. The presence of E l l-tetradecen-1-01 acetate (Ell-14:Ac) decreased the males' responsiveness to the aldehydes. Its effect appeared to be attenuated, when present at low levels with 9515 EIZ11-14:Ald, by the presence of 14:Ald, but it is still unclear what effects low levels of E l 1-14:Ac have on male behaviour.
