Oilseed rape, together with its industrial, biological and agricultural advantages, appears as a good host plant to a lot of harmful insects. They appear often as a calamity and lead to considerable damages. Thus, the aim of the present investigation is to approve the influence of some pest control chemicals against cabbage bugs -Eurydema ornata L. and pollen beetles - Meligethes aeneus F. We carried out the investigation in 2004/2005. Each of the chemicals was used in three different concentrations in order to determine the concentration dependency effect. The mortality rate was calculated by the Berims formula. Based on the results it was established that Vaztak 10 EK in concentration 0.03% could be recommended as a preparation with multipurpose effects against pollen beetles - Meligethes aeneus F. and cabbage bugs – Eurydema ornata L.
