Problems in defining synergists and inhibitors of the oriental fruit moth pheromone by field experimentation
1974
ROTHSCHILD, G.H.L.
The influence of dodecyl acetate on the response of male Grapholitha molesta to pheromone sources was observed under field conditions. Males were not trapped at live virgin female or synthetic pheromone sources when dodecyl acetate was present in the same trap or within 15 cm of the bait. Capture rate was still reduced at 30 cm separation but not at 60 cm. When dodecyl acetate was present as a background odour over a large area, catches of males at pheromone traps increased significantly. Reasons for these results remain obscure but the findings show that care is needed in the evaluation for possible control purposes of compounds which modify male sexual activity.
