Summary: | Abstract
Extracts of the female sex pheromone gland of the carpenterworm moth,
H
olcocerus vicarius
(
W
alker) (
L
epidoptera:
C
ossidae), a pest of
U
lmus pumila
L
. (
U
lmaceae), were found to contain
Z
7‐tetradecenyl acetate (
Z
7‐14Ac),
E
3‐tetradecenyl acetate (
E
3‐14Ac), (
Z
3,
E
5)‐tetradecenyl acetate (
Z
3,
E
5‐14Ac), and
Z
7‐tetradecenyl alcohol (
Z
7‐14
OH
) by coupled gas chromatographic‐electroantennographic detection (
GC
‐
EAD
) and coupled gas chromatography‐mass spectrometry (
GC
‐
MS
). Field trapping studies with impregnated rubber septa indicated that
Z
7‐14Ac was essential for attraction of males of
H
. vicarius
. However, the most attractive blend contained
Z
7‐14Ac,
E
3‐14Ac,
Z
3,
E
5‐14Ac, and
Z
7‐14
OH
in a 50:22:17:10 ratio. Our results demonstrated that a blend of
Z
7‐14Ac,
E
3‐14Ac,
Z
3,
E
5‐14Ac, and
Z
7‐14
OH
represented the sex pheromone of
H
. vicarius
. The optimized four‐component lure blend may be useful for monitoring
H
. vicarius
infestations and mating disruption. |
