There is described a device which develops an attractive and toxic action for combatting insects, consisting of a substrate of fibers and/or fibrils containing, either in an adsorbed or dispersed form, a pheromone, and which is partially coated with a layer impermeable to the phermone, the layer carrying, adhering to its external surface, an insecticide or a substrate impregnated with an insecticide.

Device developing an attractive and toxic action for fighting insects

Dispenser for the slow release of volatile pheromones comprising an adsorbing substrate of fibrils and/or fibers or their mixtures containing the active ingredient adsorbed or dispersed therein and coated with a layer which is impermeable to pheromones.

Dispenser for the slow release of volatile products

Mixtures containing (Z)-5-dodecenyl-acetate optionally combined with other compounds are shown to have a high attracting power for the male insects of the species Cossus cossus. Said mixtures may be employed in traps both for a monitoring action on the population density in a certain area and for mass-captures, or they may be employed for permeating the air in a certain zone, thus preventing the insects from mating.

Sexual attracting mixtures for Cossus cossus (Lepidoptera)

There is provided a trap for capturing insects, the trap containing a sticky glue and an attracting substance and consisting of two rectangular plates of paperboard or other suitable foldable material, the plates being arranged in the shape of overlapping bent tiles with facing concavities and placed transversely to each other, so as to form four openings along the four different sides of the rectangular plates.
