The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classification. In this context, the B Brazilian meg...

Phytoseiidae is composed of essentially predatory mites most commonly found on the aerial plant parts. Presently, it is considered to contain about 2,650 valid species, divided into nearly 102 genera of three subfamilies: Amblyseiinae, Phytoseiinae and Typhlodrominae. Approximately 250 of those have been reported from Brazil. Amblyseiinae is the la...

Arrenoseius lofegoi n. sp. (Mesostigmata: Phytoseiidae) is described based on specimens collected from Saccharum officinarum L. (Poaceae), in Camamu municipality, Bahia state, Northeast Brazil. A world key for the identification of the species of the genus is presented.

Scientific collections constitute a valuable source for contributions to scientific research and the training of human resources in systematics, but also other areas of biological knowledge. In this contribution, we intend to discuss these advancements in collections and the role played by FAPESP in sponsoring them, as well as a general overview of...

The contribution of the BIOTA/FAPESP Program to the advancement of the knowledge on terrestrial invertebrates. Biota Neotropica 22(spe): e20221398. https://doi. Abstract: The variability of the organisms living in a given area constitute what is referred to as biodiversity, one of nature's fundamental properties, responsible for the balance and sta...

The aim of this work is to report the presence of the flour mite, Acarus siro L. (Astigmatina: Acaridae), in Senador Amaral, state of Minas Gerais, Brazil. Specimens of this species were recovered from litter of a poultry house in 2018, 2019 and 2020, as confirmed by morphological and molecular identification. This is the first confirmed report of...

Blomia tropicalis and Dermatophagoides pteronyssinus play an important role in triggering allergy. Glycycometus malaysiensis causes IgE reaction in sensitive people, but is rarely reported in domestic dust, because it is morphologically similar to B. tropicalis making the identification of these species difficult. The identification of mites is mos...

Phytoseiidae Berlese (Acari: Mesostigmata) is a family of predatory mites found mostly on the aerial plant parts. Several phytoseiid species are commercialized as biological control agents. Even though Brazil is the fifth country with the highest number of valid species, knowledge about the phytoseiid fauna in different Brazilian states is highly v...

The family Winterschmidtiidae is subdivided into four subfamilies; representatives of two are associated with insects and those of other two commonly inhabit decaying materials, fungi, plant leaves, vertebrate nests and stored food. Species of this family are frequently collected during surveys of arboreal acarofauna in Brazil, but in most cases, t...

Rhizoglyphus species are commonly found associated with subterranean plant organs, where they may lead to direct or indirect damages. The diversity of this genus in Brazil is poorly known and the most frequently mentioned species in the country is Rhizoglyphus echinopus (Fumouze & Robin). However, this species appears on the A1 quarantine list for...

Há algum tempo, quando produtores rurais e técnicos ligados ao agronegócio reuniam-se para trocar informações e experiências a respeito do manejo de pragas nas principais regiões agrícolas brasileiras, a única estratégia pautada era o controle químico. Quase nenhuma importância era dada ao controle biológico aplicado, e pouco era comentado sobre o...

Laelapidae and Rhodacaridae are important families of edaphic predatory mites and species of these families have been considered for use in biological control programs of soil pests. Mites of Cohort Astigmatina (Acari: Sarcoptiformes) have been largely used as factitious prey in the mass rearing of various edaphic or plant-inhabiting predatory mite...

A new species Thyreophagus cracentiseta n. Sp. is described morphologically based on adult females, adult homeomorphic and heteromorphic males collected from chicken feed in Brazil. The Thyreophagus species associated with stored food and human habitats are reviewed, and a key to separate species of this genus is provided.

Phytoseiids are possibly the most important mites used in biological control and are usually produced using a tritrophic system that, although efficient, is expensive and laborious. Mites of the cohort Astigmatina (Sarcoptiformes) have been used as factitious prey in the mass rearing of phytoseiids and may allow a much simpler production system. Th...

A new genus, Ingaseius nov. gen., and a new species, Ingaseius silvaticus nov. sp., Phytoseiidae, collected from Inga edu-lis Martius and Inga marginata Wild. (Fabaceae) are described from the Brazilian Atlantic Forest. This species is unique in the following characteristics: females and males with few teeth on fixed cheliceral digit and short Jv5,...

This work describes the results of a study of the phytoseiid mites collected from plants in two natural ecosystems in the State of Sao Paulo, Brazil-Cerrado and Atlantic Forest. In this study, 40 phytoseiid species are reported. Measurements of different structures are given for species for which measurements for the respective Sao Paulo population...
