Abstract: | Summary Sticky traps containing (+)-lineatin, the pheromone of the ambrosia beetle,Trypodendron lineatum, attracted the predatorThanasimus formicarius to about the same extent as traps baited with ipslure, the pheromone blend used for mass-trappingIps typographus. The results indicate thatT. lineatum is an important prey forT. formicarius early in the season before the main prey becomes active. Addition ofexo-brevicomin to ipslure and ethanol and/or -pinene to (+)-lineatin did not significantly influence the catches of the predator. |
