Based on analysis of pheromone gland extracts, highly attractive new baits have been developed for three click beetle pests. That for Agriotes brevis is a mixture of geranyl butanoate and ( E,E )‐farnesyl butanoate, and that for A rufipalpis and A sordidus contains geranyl hexanoate alone. From known data from species populating Russia, optimized bait compositions for species in Central and Western Europe were developed as follows: geranyl octanoate + geranyl butanoate for A lineatus , geranyl isovalerate for A litigiosus , geranyl hexanoate + geranyl octanoate for A obscurus , geranyl butanoate alone for A sputator and ( E,E )‐farnesyl acetate alone for A ustulatus . Although slight differences were found in gland contents with A litigiosus var laichartingi and fenotypus typicus , nevertheless there were no differences in response to the optimum bait. There were no differences in pheromone composition or response to the optimized bait between the two morphological forms (‘black’ and ‘red’) of A ustulatus . As a result of these studies, highly effective pheromone baits are now available for monitoring and population reduction in all important pest click beetle species in Central and Western Europe. © 2003 Society of Chemical Industry
