Platypus cylindrus Fab. (Coleoptera: Curculionidae) present xylophagous group of insect which decrease economic and aesthetical value and technical properties of wood. In previous decades, this problem was solved with application of Lindane (Hexachlorocyclohexane HCH) insecticide, but contemporary regulations excluded its use. Therefore, experiments with use of alpha-cypermethrin insecticide for protection of oak timber was performed. Experiments were established at Forest estate Sremska Mitrovica of Public Enterprise Vojvodinašume Serbia on two spatially divided localities MU Blata-Malovanci and MU Neprečava Varoš Lazarica. On each locality experiments were divided to Fastac® Forst application with 1% concentration for 1 month period of protection and 2% for 3-month protection period. Efficacy was calculated by Abott's formula. Fastac® Forst application in concentration of 1% for protection period of 30 days showed 100% efficacy, while application of 2% concentration for 90 days protection period showed 92,37 %% and 100% efficacy. Obtained results indicate good efficacy of application of Fastac® Forst for oak wood protection.
