Integrated Pest Management (IPM) is an ecosystem approach to crop production and protection that combines different management strategies and practices, i.e. biological control, mechanical control,  cultural control, chemical control, to grow healthy crops and minimize the use of pesticides.
Since 1970s entomologists and ecologists have urged the adoption of IPM for pest control both to reduce the environmental impacts related to the extensive use of chemical pesticides and to face their inefficiencies.
The IPM goal is to maintain pest damage at economically acceptable levels while protecting the environment and human health.
