Resistance to imidacloprid (Confidor 70 WG) in damson hop aphid (Phorodon humuli Schrank) on Czech hops

Popis výsledku v původním jazyce

Contemporary hop protection against damson-hop aphid (Phorodon humuli Schrank) in Czech Republic has been for almost fifteen years nearly entirely based on the application of imidacloprid as a key aphicide. In the years with slighter to average intensityof migration one treatment by imidacloprid is usually sufficient enough to control this dangerous pest. In spite of its still good efficiency there have been some hop gardens where aphids survive after imidacloprid application perhaps as a result of theprevious under-dosing. To investigate the tests in Potter tower. Values LC 50 of field strains were compared with the same ones of a susceptible strain so as to be able to determine resistance factors (RF). Obtained data show the resistance in damson-hop aphid feeding on Czech hops. Nevertheless, biological efficiency for practical hops protection against P. humuli although there is an urgent need for a new efficient aphicide.
