The family Phytoseiidae includes many species of predators involved in the control of mite pests of crops all over the world. In European vineyards, these natural enemies play a key role in plant protection as their presence usually makes the use of acaricides unnecessary. Each species has its specific biological features. It is thus of great interest to identify the species reported on grape, ...

This paper announces a database on the taxonomy and distribution of mites of the family Phytoseiidae Berlese, which is available online at http://www.lea.esalq.usp.br/phytoseiidae/. Synthesis of species diversity per genus, subfamily and country are given. Information about use of the database is provided.

Several species of the predatory mite family Phytoseiidae are of major economic importance for biological pest control in crops, including grapevines. Plant diversification in agrosystems is reported to enhance useful biodiversity and provide ecosystem services. Thus, agroforestry, which consists in co-planting trees and crops, is assumed to be a possible way to ensure regulation of pest outbre...

The immature stages of four species of Kampimodromus Nesbitt (Acari: Phytoseiidae) from Italy and Croatia have been studied and identified both at stage and species level. Larval stages of Kampimodromus corylosus Kolodochka and all immature stages of Kampimodromus ericinus Ragusa di Chiara & Tsolakis and Kampimodromus langei Wainstein & Arutunjan are described for the first time. The relative l...

Adequate distribution of natural enemies is necessary for successful augmentative biological control. In California greenhouse cut roses produced using the bent shoot system, the predatory mite Phytoseiulus persimils is widely used for control of the phytophagous mite Tetranychus urticae. One purported advantage of the bent shoot method is that the dense foliage of the lower canopy creates inte...

A new genus, Ingaseius nov. gen., and a new species, Ingaseius silvaticus nov. sp., Phytoseiidae, collected from Inga edulis 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, without J2, Z1 and leg macrosetae. In addition,...

A new species of phytoseiid mite of the genus Neoseiulus (Acari, Phytoseiidae) found in Svalbard is described and illustrated. Redescriptions, drawings, measurements, and diagnosis of two related species, N. magnanalis (Thor) and N. ellesmerei (Chant & Hansell) are given. A neotype is designated for N. magnanalis.

The functional response of the phytoseiid predator Chileseius camposi González y Schuster, 1962 (Acarina:Phytoseiidae) on densities of its prey Panonychus ulmi (Koch, 1836) was evaluated under controlled temperature (20 +/- 2 degrees C), relative humidity (75 +/- 15%) and photoperiod (16:8h L:D). A functional type II response was displayed (Holling's disk). Holling, Wolf transformation and Roge...
