Abstract

The most important way to control the pests is to not use chemicals, preventing the environmental pollution in the different ecosystems. We proposed to study and apply the unchemical methods according to ecological pest management, to control some pesticide resistant pests. The research has been oriented to the physical methods: the use of the light radiation reflected by different materials (supports), directly applied on the hostplant leaves or on the ground, which remove the insects from the damaged zone; the use of visual traps (coloured panels and coloured plates), which attract and capture the insects. The researches were carried out in 2002, with five experiences organised in two ecosystems (orchard and mountain grazing). The both categories of methods were very effective.
