Sažetak

The population of plum sawflies (Hoplocampa flava L. and Hoplocampa minuta Christ.) was studied in the orchard "Maksimir" at the Faculty of Agriculture in Zagreb. White adhesive plates were placed on the plum cultivar 'Čačanska pozna' and monitoring lasted from March 7 to April 25, 2019. The presence of both plum sawflies was established on April 4 at the beginning of the plum blossom, and population abundance was changing during the plum blossom phases. At the beginning of the plum blossom the highest number of yellow plum sawfly was recorded (209 individuals) while the highest number of black plum sawfly was recorded in the full bloom stage (103 individuals). Considering that the population of plum sawflies is regularly high in Croatian plum orchards, it has not been known so far whether the flight dynamics of these two species differ from each other, as it was confirmed by this study. Monitoring results showed the dominance in abundance of yellow plum sawfly in the research orchard, but both species develop in high populations which can cause greater damage to plum production in the investigated orchard.
