The seasonal specifity of weevil invasion.
Original language description
The invasion of weevils to rapeseed crop was monitored using yellow traps. The dominant species of weewils monitored was Ceutorhynchus pallidactylus. In 2008 males came first, females flew after two weeks and a low number of imagoes were caught in traps.In 2009, males and females flew simultaneously, a high number of imagoes was catched in traps. In 2010 started males and females migrate simultaneously, substantially higher number of males was detected in March, and in April the captures decreased rapidly. The counts of larvae in untreated stems were similar in every season, whereas counts of adults in yellow traps differed substantially. The yellow traps proved inaccurate in cold and rainly seasons. Insecticide used to control pollen beetles can simultaneously be used to control the population of C pallidactylus, wher is C. pallidactylus domnant..
