Scientists in Northern Italy are experimenting with unusual and totally eco-friendly sound and odour devices to fight off insects from their cultivated fields. And their studies suggest that these methods could be as efficient in protecting crops as using chemical based pesticides. In the meantime, in a field study near Pisa, Italy, researchers are learning how important it is to keep semi-natural habitats next to cultivated fields. These areas are an important resource for pollinators and it now seems they even have an impact on the yield of the cultivated crops.
