Phytoseiidae is the most important family of plant inhabiting predatory mites. These mites are extensively used as biological control agents for management of mite and insect pests of crops grown in greenhouses and in open field. Interest in research on phytoseiids has steadily increased worldwide during the last 50 years, resulting in a large numb...

A new genus and species of the subfamily Typhlodrominae are described from the Brazilian Amazon. The main differences between this and all other phytoseiid species are the presence of two unpaired setae on dorsal shield of deutonymphs and adults, and the absence of all ZV setae. It also differs from other typhlodromine species by its relatively lon...

Cecropia pachystachya Trec. (Urticaceae) is a common pioneer plant from South America, which is found on both degraded and preserved environments.

Catálogo Taxonômico da Fauna do Brasil: se ng the baseline knowledge on the animal diversity in Brazil

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...
