Research Concerning the Effect of Synthetic Pheromones on Pityogenes chalcographus L. in Braşov County

Abstract

In this paper we study one of the most important bark beetles of spruce, namely the six-spined spruce bark beetle (Pityogenes chalcographus L.). For this species of Scolytinae we tried to achieve two main objectives: testing the efficiency of two types of synthetic pheromones and study of the local flight dynamics of this insect. Therefore, it is necessary to know the local characteristics of the flight of the six-spined spruce bark beetle in order to be able to intervene at the moment when the population begins its outbreak.
