Pyrethroid resistance

Pollen beetle resistance to pyrethroid insecticides is now widespread throughout the UK. IRAC’s 2012 monitoring of pollen beetle populations found only 20% were susceptible and showed a further increase in the proportion of resistant and highly resistant populations.

Pollen beetle resistance to pyrethroid insecticides is now widespread. IRAC’s 2012 monitoring of pollen beetle populations found only 20% were susceptible and showed a further increase in the proportion of resistant and highly resistant populations.

This means that if you need to control pollen beetle there’s a high risk that a pyrethroid will not be effective. An integrated pest management strategy to contend with resistance is therefore essential.
