COMPARISON OF SPRUCE BARK BEETLE (IPS TYPOGRAPHUS) CATCHES BETWEEN TREATED TRAP LOGS AND PHEROMONE TRAPS
Original language description
The numbers of Ips typographus beetles captured in treated tripod trap logs (tripods) were compared to catches from Theysohn pheromone traps (TPTs). In 2010, at each of the three localities, five TPTs and five tripods baited with Pheagr IT pheromone evaporators were installed with 10 m spacing. Weekly inspections were made during the entire period of I. typographus flight activity (April 30 ? October 1). The tripods were treated with insecticide Vaztak 10 SC on April 23, 2010 and then repeatedly every seven weeks along with the renewal of the pheromone evaporator. The study showed that the TPTs trapped approximately one-third more beetles than did the tripods. The TPT captures showed a dominance of females over males, while in tripods the sex ratio wasbalanced. The TPTs and tripods both trapped approximately the same numbers of males, but the females were distinctly more numerous in the TPTs. In both cases, more adults were captured during spring than in summer.
