The nun moth Lymantria monacha L. and pine lappet moth Dendrolimus pini L. belong to the insects occurring in cyclical outbreak threatening the sustainability of Scots pine Pinus sylvestris L. forests. The populations of both species are reduced in aerial treatments carried out in Poland on thousands of hectares. Therefore there still is a need to implement to the forest practice insecticides that characterize by high efficiency and meet the safety standards for the environment. The aim of the study was to evaluate the effectiveness of Mimic 240 LV (24% of tebufenozide) in the control of nun moth and pine lappet moth populations. Aerial treatments were performed in 55−80−years old Scots pine stands located in three forest districts on the area of Regional Directorate of the State Forest in Zielona Góra (western Poland). The experiment consisted of one aerial spray to limit the population of nun moth with the use of tested insecticide at a dose of 0.3 l/ha and two aerial treatments to control pine lappet moth with a doses of 0.4 and 0.5 l/ha. The treatments were conducted with the use of Dromader M−18 and AN−2R aircrafts equipped with Micronair AU 5000 atomizer. The insecticide was mixed with adjuvant Ikar 95 EC (mineral oil) and water, and applied at a dose of 3 l of spray solution/ha. In the case of L. monacha, evaluation of treatment efficacy showed insect mortality at the rate of 98.7%. The lower and higher doses of Mimic 240 LV caused the mortality of 90.4% and 97.2% of D. pini caterpillars respectively. The obtained results confirm a high efficacy of tested insecticide, which can be recommended for aerial applications in the forest practice.
