Fish-liver oil as repellent in IPM

In our experiments lasting several years, we have found repellent activity of fish oil on wildlife and some insects. The specific smell of fish-liver oil is not similar to the smell of plants which are attractive for phytophaga, vertebrates, or insects. Sulphatised fish-liver oil applied on plants changes the plants natural smell which disappears, and the smell of fish-liver oil acts as a repellent on some kinds of pests. The sequence of attacks (attractant, arrestant, incitant, phagostimulant) is interrupted already in the search phase. The plant smelling of fish-liver oil is not attractive and becomes repellent to pests and wildlife.
