“…We confirmed an earlier report by Klun et al (1982) that 14:Ald and Z9-14:Ald were present in Hs females. Because other studies did not find these compounds in Hs (Teal et al, 1981;Tumlinson et al, 1982;Heath et al, 1991), it was questionable whether they were produced by Hs at all (Vickers, 2002).…”

“…The mass spectrum of Z9-14:Ald showed M + − 18 at m/z 192, which is characteristic of C 14 monounsaturated aldehydes. Based on these results, together with the earlier identification by Klun et al (1982), we are confident that both 14:Ald and Z9-14:Ald were present in Hs females.…”

“…Species specificity of the pheromone signal is achieved by the presence of specific pheromone components, and the relative amounts of these components in the pheromone blend. For example, most noctuid moths in the genera Heliothis and Helicoverpa use (Z )-11-hexadecenal (Z11-16:Ald) as the major component of their pheromone blends, but vary the types and relative amounts of minor components (e.g., Roelofs et al, 1974;Tumlinson et al, 1975Tumlinson et al, , 1982Klun et al, 1980aKlun et al, ,b, 1982Teal et al, 1981Teal et al, , 1984Pope et al, 1982Pope et al, , 1984Ramaswamy et al, 1985;Vetter and Baker, 1984;Heath et al, 1991;Choi et al, 2002). The closely related Heliothis virescens (Hv) and H. subflexa (Hs) both produce small amounts of hexadecanal (16:Ald), (Z )-7-hexadecenal (Z7-16:Ald), and (Z )-11-hexadecenol (Z11-16:OH).…”

“…Whereas the acetates are completely absent in the glands of Hv, Z9-16:Ald can be found in trace quantities. Even though a number of studies have been conducted to determine the pheromone compositions of Hv (Roelofs et al, 1974;Tumlinson et al, 1975Tumlinson et al, , 1982Klun et al, 1980;Pope et al, 1982;Heath et al, 1991) and Hs (Teal et al, 1981;Tumlinson et al, 1982;Klun et al, 1982;Heath et al, 1991), the female pheromone component emission ratios and rates, and the relative importance of various blend components to males, have not been fully resolved (Vickers, 2002).…”

EFFECT OF PBAN ON PHEROMONE PRODUCTION BY MATED Heliothis virescens AND Heliothis subflexa FEMALES

et al. 2005

Abstract-Mated female Heliothis virescens and H. subflexa were induced to produce sex pheromone during the photophase by injection of pheromone biosynthesis activating neuropeptide (PBAN). When injected with 1 pmol Hez-PBAN, the total amount of pheromone that could be extracted from glands of mated females during the photophase was similar to that extracted from virgin females in the scotophase. The PBAN-induced profile of pheromone components was compared between mated, PBAN-injected females and virgin females during spring and fall. Virgin females exhibited some differences in the relative composition of the pheromone blend between spring and fall, but no such temporal differences were detected in PBAN-injected, mated females. Because the temporal variation in pheromone blend composition was greater for virgin females than for PBAN-injected females, PBAN can be used to determine a female's native pheromone phenotype. This procedure has the advantages that pheromone glands can be extracted during the photophase, from mated females that have already oviposited.

“…The pheromone blends of both species contain (Z)-11-hexadecenal (Z11-16:Ald) as the major component and different relative amounts of tetradecanal (14:Ald), (Z)-9-tetradecenal (Z9-14:Ald), (Z)-7-hexadecenal (Z7-16:Ald), (Z)-9-hexadecenal (Z9-16:Ald), and (Z)-11-hexadecenol (Z11-16:OH) (34,(41)(42)(43)(44)(45)(46)(47)(48)(49)(50). In addition to the major component, Z9-16:Ald and Z11-16:OH are essential for the attraction of Hs males (34,49,51), whereas Hv males are attracted to a minimal blend consisting of Z11-16:Ald and Z9-14:Ald (41)(42)(43)48).…”

Sex pheromones of many moth species have relatively simple structures consisting of a hydrocarbon chain with a functional group and one to several double bonds. These sex pheromones are derived from fatty acids through specific biosynthetic pathways. We investigated the incorporation of deuterium-labeled tetradecanoic, hexadecanoic, and octadecanoic acid precursors into pheromone components of Heliothis subflexa and Heliothis virescens. The two species utilize (Z)11-hexadecenal as the major pheromone component, which is produced by Delta11 desaturation of hexadecanoic acid. H. subflexa also produced (Z)11-hexadecanol and (Z)-11-hexadecenyl acetate via Delta11 desaturation. In H. subflexa, octadecanoic acid was used to biosynthesize the minor pheromone components (Z)9-hexadecenal, (Z)9-hexadecenol, and (Z)9-hexadecenyl acetate. These minor components are produced by Delta11 desaturation of octadecanoic acid followed by one round of chain-shortening. In contrast, H. virescens used hexadecanoic acid as a substrate to form (Z)11-hexadecenal and (Z)11-hexadecenol and hexadecenal. H. virescens also produced (Z)9-tetradecenal by Delta11 desaturation of the hexadecanoic acid followed by one round of chain-shortening and reduction. Tetradecanoic acid was not utilized as a precursor to form Z9-14:Ald in H. virescens. This labeling pattern indicates that the Delta11 desaturase is the only active desaturase present in the pheromone gland cells of both species.
