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...
BACKGROUND: Previous work has characterised pyrethroid resistance in pollen beetle (Meligethes aeneus F.) as principally an oxidative mechanism. Piperonyl butoxide (PBO) can synergise this resistance in the field, but its effects on the honey bee are thought to be unacceptable.
RESULTS: A field trial in Poland was conducted to show that a mixture of PBO and tau‐fluvalinate at the registered rate gave...
