Abstrakt

Three neonicotinid insecticides: Apacz 50 WG, Confidor 200 SL and Mospilan 20 SP were used to control acorn pests Curculio spp. (Curculionidae: Coleoptera) and Cydia spp. (Tortricidae: Lepidoptera) in the oak (Quercus robur) seed orchard in the Leżajsk Forest District (South-Eastern Poland). The best effect was observed on the plot treated with insecticide Apacz 50 WG, where only 3% of acorns were damaged by Curculio spp. larvae. The percentage of damaged acorns was significantly higher on plots treated with Confidor 200 SL and Mospilan 20 SP – 30% and 35%, respectively. The level of acorn infestation by Cydia spp. larvae was less than 2% of seeds on all analyzed plots.
