The aim of this study was to evaluate the influence of insecticides against stem weevils on rapeseed yield and profitability. Long-term field trials were carried out in Kromeriz, Czech Republic. Insecticide application led to the increase of rapeseed yield in 8 years out of 9 years monitored (2002, 2004-2011). There was no correlation between the incidence of stem weevils in traps and yield levels (or yield increase).
