Tarsonemid mites (Acari: Tarsonemidae) on myrtaceous plants of the Atlantic Forest, Brazil, with description of a new species of Tarsonemus Canestrini amp; Fanzago.

A survey of tarsonemid mites associated with plants of the family Myrtaceae was conducted in seven areas of the Atlantic Forest biome. Fourteen known species were registered; other 21 morphospecies was identified up to genus level. Additionally, a new species, Tarsonemus conduru Lofego Cavalcante sp.

Reinstatement of Metatarsonemus Attiah (Acari: Tarsonemidae), with description of a new species, redefinition of the genus and a key to the world species.

A new species, Metatarsonemus caissara Lofego Cavalcante sp. nov., is described based on females and males collected on Eugenia umbelliflora O.

Potential of Five Brazilian Populations of Phytoseiidae (Acari) for the Biological Control of Bemisia tabaci (Insecta: Hemiptera).

Biotype B of the whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), causes considerable losses to growers worldwide. Phytoseiid mites have been successfully used for the control of this pest in several countries. The Brazilian phytoseiid fauna is very diverse and potentially useful for this purpose.

Potential of two populations of Amblyseius swirskii (Acari: Phytoseiidae) for the control of Bemisia tabaci biotype B (Hemiptera: Aleyrodidae) in Brazil.

Predatory mites of the family Phytoseiidae are commercialized in European and North American countries for the control of whiteflies (Insecta: Aleyrodidae). Amblyseius swirskii Athias-Henriot (Acari: Phytoseiidae) is one of the predators used for that purpose. This predator is not found in Brazil and in many other countries, but its introduction could promote biological control of Bemisia tabaci (Gennadius) biotype B (silverleaf whitefly) in those countries.
