The study was carried out to evaluate the possibilities to control the common pine sawfly Diprion pini L. with the use of plant protection products Mospilan 20 SP (20% acetamipryd) and Trebon 30 EC (300 g etofenprox/l). Aerial insecticide treatments were applied onto experimental plots (100 ha) in Scots pine stands, sprayed with approximately 3 l of spray solution/ha. Mospilan 20 SP at a rate 0.20 kg/ha caused 61%-76% mortality of D. pini larvae, whereas at a rate 0.25 kg/ha – 100% larval mortality. Trebon 30 EC aerial treatments at a rate 0.2 l/ha resulted in 100% larval mortality. Study results will be enclosed in the procedure of registration of the plant protection products for use in forestry.
