    Abstract: The invention relates to a device for dispensing bark beetle pheromone in a controlled manner. Said device consists of a plastic container comprising one or more sealed chambers, each containing a liquid pheromone that is composed of 2-ethyl-1,6-dioxaspiro[4,4]nonane, 2,4-decadiene carboxylic acid methyl ester and at least one alcohol selected from 2-methyl but-3-en-2-ol and 2-methylbut-3-in-2-ol, at least 50 % of the surface of the walls that form the chambers having a wall thickness ranging between 0.1 and 1 mm. At least said surfaces consist of a plastic material that is an uncoated vinyl acetate ethylene copolymer with a vinyl acetate content ranging between 10 and 17 wt. %. The invention also relates to a method for combating and controlling the swarming behaviour of the species Pityogenes chalcographus, which is also known as the six-toothed spruce bark beetle.

    Abstract: The present invention relates to a device in the form of a container made of a polymer material, which container has one or more sealed chambers, each of which comprise a liquid pheromone comprising 2-ethyl-1,6-dioxaspiro[4,4]nonane, methyl 2,4-decadiene-carboxylate and at least one alcohol selected among 2-methylbut-3-en-2-ol and 2-methylbut-3-yn-2-ol, where at least 50% of the area of the walls forming the chambers have a wall thickness in the range of from 0.1 to 1 mm and the polymer material which forms the chamber is at least in those areas an uncoated vinyl acetate/ethylene copolymer with a vinyl acetate content in the range of from 10 to 17% by weight. The invention also relates to a method of combating and for monitoring the swarming behavior of the species Pityogenes chalcographus, generally also referred to as spruce wood engraver or six-dentated bark beetle.

    Abstract: The invention relates to a natural method for controlling bark beetle populations by controlling the predators of bark beetle. Said method comprises aggregating bark beetle predators in the natural environment of the bark beetles by applying a chemical attractant effecting attraction of predators of the bark beetles to be controlled in those locations where a control of the bark beetle population is desired.
