IPM Strategies Through Specialist and Generalist Phytoseiids (Acari, Mesostigmata)

Abstract

The exploitation of natural enemies, especially the predaceous mites phytoseiids, has become a fundamental factor for IPM in integrated crop production in Europe and worldwide. In controlling harmful insect and mite species, various species/strains from this group of predators are commonly used and marketed. Intrinsic biological traits of phytoseiids allow their ranking in different life style types. These factors, together with their quick adaptability to face new emergencies (i.e. phytophagous and exotic pests outbreaks and new environment or climatic conditions) confirm their role as a significant and sustainable tool in biological control. In this chapter the foundations for a more intensive adoption of phytoseiids are underlined, including the enhancement and introduction of new strategies aiming at a long term and efficient pest control.
