Chemical plant protection is still an indispensable method in effective oilseed rape protection against the pollen beetle (Meligethes aeneus F.) in Poland. This species is able to develop strong resistance against active substances used in synthetic insecticides. The phenomenon of pollen beetle resistance is currently found in many European countries. Therefore the objective of the study was to determine the present susceptibility level of Polish populations of pollen beetle to the main groups of insecticides recommended in Poland for pollen beetle control. The research showed high resistance of most tested Polish pollen beetle populations to many active substances of all chemical groups of insecticides applied in Poland.
