In order to develop efficient lures for soybean pod borer
Leguminivora glycinivorella (Matsumura) in China, (
E,E)-8,10-dodecadienyl acetate (
EE-8,10-12:Ac), the main component of the pheromone of
L. glycinivorella, and 12 structurally-related compounds were synthesised in good overall yields, regiospecificities, and stereo-selectivities via coupling reactions catalysed by Li
2CuCl
4. The effect of different synthetic compounds, alone or in combination with
EE-8,10-12:Ac, on numbers of captured
L. glycinivorella males was evaluated.
EE-8,10-12:Ac, (
E)-10-dodecenyl acetate
(
E-10-12:Ac), (
E)-8-dodecenol (
E-8-12:OH),
tetradecyl acetate (14:Ac), and (
Z)-9-tetradecenyl acetate (
Z-9-14:Ac) alone displayed different attractiveness to
L. glycinivorella males. 14:Ac,
E-8-12:OH,
E-10-12:Ac, (
E,E)-8,10-dodecadienal (
EE-8,10-12:Ald), (
E)-8-dodecenal (
E-8-12:Ald), (
E)-10-dodecenal (
E-10-12:Ald) and
Z-9-14:Ac all showed a synergistic effect to
EE-8,10-12:Ac at certain dosages. The binary mixtures of
EE-8,10-12:Ac and
E-10-12:Ald,
Z-9-14:Ac,14:Ac,
E-8-12:Ald,
EE-8,10-12:Ald,
E-8-12:OH, or
E-10-12:Ac in suitable ratios give 17.00-, 10.98-, 10.67-, 6.73-, 5.54-, 4.30- and 4.50-fold increases in trap catch, respectively, over the standard pheromone lure, and as novel pheromone blends, demonstrated potential use in pheromone traps to monitor or control
L. glycinivorella populations in China.
