Abstract: A trap for catching living insects, specifically fruit flies, is provided having a catch container, a base, and a funnel-shaped insert. The funnel shaped insert has a funnel wall, a plurality of slits in the funnel wall, and a funnel exit opening. The insects to be caught are able to slip through the funnel exit opening, but not through the slits. Furthermore, the trap includes an attractant container in the catch container and/or in the base having a liquid attractant and a wick. The insects are attracted by the scent of the liquid attractant evaporating from the attractant container and fly or crawl through the funnel exit opening into the catch container, where they become trapped. The user can then carry the trap outside, remove the funnel-shaped insert, and release the captured insects alive outside. In this way, the insects can be kept out of human living and working spaces without killing the insects.

Abstract: Method for supporting the preservation of the insect population, having the following steps of: determining the lethal effect of a product unit on an insect population, determining a difference in the insect population on the basis of the effect of a particular quantity of product units, determining the actual insect population in a predetermined area, determining a desired insect population in the predetermined area, which desired insect population is derived from the actual insect population in the predetermined area and the difference in the insect population, and creating a basis of life for the desired insect population in the predetermined area by adapting the biological nature of the predetermined area.
