Current Status of Phytoseiid Mites as Biological Control Agents in Latin America and Experiences from Argentina Using Neoseiulus californicus

Abstract

Phytoseiidae is a large family of Mesostigmata mites. Members of this family are important biological control agents across the world since they are well-known natural enemies of phytophagous arthropods on cultivated and non-cultivated plants, mainly used to control pest spider mites. However, some can control thrips in greenhouses and fields. Several studies reporting on species in Latin America have been published. The most extensive studies were conducted in Brazil. Phytoseiid mites have been used in different biological control approaches, with two successful classical biological control programs: the biocontrol of the cassava green mite using Typhlodromalus aripo (Deleon) in Africa and the citrus and avocado mites by Euseius stipulatus (Athias-Henriot) in California. Efforts in using phytoseiid mites to enforce biological control of different phytophagous mites are being made in Latin America. Till now, only a few successful examples are available on this topic. This fact highlights the need to continue the investigations on the ability of other unknown species to be used in biological control through close collaboration between researchers and biocontrol companies. Various challenges remain, such as developing better rearing systems to provide a large number of predators to farmers in various crop systems, training farmers to improve their understanding of the use of predators, and chemical control aimed at conservation biological control, looking forward to increasing the use of the phytoseiid mites as biological control agents in Latin America and the Caribbean.
