Abstract

BACKGROUND: Pollen beetle (Meligethes aeneus F.) has become the most important pest of oilseed rape in Europe, but its control has been greatly hindered by pyrethroid resistance. Target-site resistance has been implicated previously, and, whilst synergism has been found with piperonyl butoxide (PBO), the exact nature of metabolic resistance has remained unknown. The use of PBO, in conjunction with its analogue EN 16/5-1, has allowed the characterisation of metabolic resistance. RESULTS: In vitro assays in combination with in vivo studies using PBO and EN 16/5-1 showed that high synergism of pyrethroids was primarily correlated with an oxidative mechanism, although a limited contribution by esterases was implicated in one population. CONCLUSION: Differential synergism has enabled the characterisation of pyrethroid resistance in populations of M. aeneus. It was found to be principally due to an oxidative-based mechanism, and, if a synergist were to be used to inhibit this enzyme group, renewed control against resistant pests could be achieved.
