The project is aimed at an innovation of plant protection methods of oilseed rape to stem weevils, Ceutorhynchus pallidactylus, Ceutorhynchus napi and at detection of occurrence of pyrethroid resistant Meligethes aeneus (sub) populations in the Czech Republic. On the base of stem weevils monitoring within the whole Czech Republic the important information for delimitation of locations with clear and long-lasting predomination of C. pallidactylus over C. napi will be obtained. The new methodics of oilseed rape protection just to C. pallidactylus will be elaborated. The methodics will be built up on the results of detailed bionomic studies of the species. The results of residual effects of insecticidal applications (primarily targeted to C. pallidactylus) on Meligethes aeneus will be a component part of the methodical access too. The findings of occurrence of pyrethroid resistant Meligethes aeneus (sub)populations within the Czech Republic will contribute to a knowledge store mapping insecticide resist (en)
Vymezit oblasti s predominancí C.pallidactylus, vytvořit metodiku ochrany proti C.pallidactylus na základě nově získaných poznatků o bionomii tohoto druhu a provést monitoring populací M.aeneus na rezistenci proti pyrethroidům (cs)
Ověření nových přístupů k ochraně řepky ozimé proti stonkovým krytonoscům založených na přesnějším monitoringu jejich výskytu a chování v porostu a testování (sub)populací blýskáčka řepkového na rezistenci proti pyrethroidům (cs)
