ESQUIVEL-AYALA, Blanca Alicia et al. Methods of rearing and reproduction predatory mites of the order Mesostigmata. Rev. Mex. Cienc. Agríc [online]. 2024, vol.15, n.3, e3676.  Epub Aug 25, 2024. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v15i3.3676.

Due to the irrational use of chemicals for pest control in intensive crops, the diversity of communities of beneficial organisms, such as the predatory mites of the order Mesostigmata, has been alarmingly diminished,. These arachnids have taken on agricultural relevance because most of their members have zoophagic feeding habits and naturally regulate harmful populations of insects, nematodes and other mites that inhabit plants. For more than 40 years, predatory mites have been introduced regularly for biocontrol work and it is estimated that more than 60% of programs use these organisms; however, the commercial products available are limited to a few species, which vary in effectiveness according to the conditions of the crop, availability of prey and competition for niches with other predatory organisms; in addition, their production is protected under trade secrecy in most cases. With this, the opportunity opens up to explore native or even already commercialized species in order to evaluate their predatory capacity at the research level or as usual tools for pest regulation; a first challenge for this purpose is propagation and culture methods. The methods for mite culture can be divided into two: maintenance on plants and in confinement; although each technique has been developed for a particular species or a certain purpose, knowing their basic design promises to bring us closer to a new line of study for their introduction and reintroduction into agricultural systems.

Keywords : agricultural pests; biological control; Blattisociidae; Laelapidae; Phytoseiidae; natural enemies.
