The abundance and species spectrum of cockchafers of the genus Melolontha and characteristics of the tribes in four forest regions of theCzechRepublic was explored. We used light traps, automatic meteorological stations and field investigations to study the course of swarming, species composition, abundance of the respective tribes, sex ratio during swarming and the dependence of swarming on the average daily temperature. Studies will continue in the next years and the objective is to use the results for prognosis of the occurrence of cockchafers and the damages subsequently caused by grubs in forest cultures.
