Summary

Insect pressure on grazing animals is increasing with global warming. Using chemical products to protect grazing animals is not permitted on organic farms. Some trees (e.g. walnuts) have a repellent effect on insects and animals could benefit from these trees in agroforestry systems. In our trial, we assessed insect pressure on 6 herds of cows on pasture with/without trees. We evaluated insect pressure per herd with one H-traps in the meadow and sticky traps in various tree type, observed defensive behaviours of cows and counted flies on the animals.
