In field tests in Hungary, traps baited with 4-methyl-3, 5-heptanedione, the aggregation pheromone of the pea and bean weevil Sitona lineatus, caught significant numbers of several other species including S. crinitus (syn. S. macularius) and S. humeralis. Lower numbers of S. suturalis, S. hispidulus and S.inops were also caught. Of the species captured in higher numbers in this study, S. crinitus is one of the most important pests of peas in Hungary, and S. humeralis causes damage to alfalfa. The other species are usually regarded as pests of secondary importance. The fact that the S. lineatus pheromone trap caught other Sitona species is very useful, since crop damage usually results from attack by a complex of pests rather than a single species. A trap capable of catching several of the pest Sitona species will be able to detect and predict overall pest pressure more effectively than a trap highly selective for a single species.
