| : | Two years experiment showed considerably numerous occurrence of Tersilochus obscurator parasitized cabbage stem weevil, than T. fulvipes. This disproportion is reflecting population ratio cabbage stem weevil/rape stem weevil. Phradis morionellus was most numerous parasitoid o pollen beetle caught in south-west Poland. Greatest risk for parasitoids of cabbage stem weevil are insecticides applied from stage then flower buds distingtly raised above the youngest leaves to the phase of the yellow bud (BBCH 55-59), however for Meligethes sp. from the phase of the yellow bud to almost the half of flowering (BBCH 58-64). |
