Reproduction in the spider mite Oligonychus yothersi (Acari: Tetranychidae).

In this work we reported injuries caused by the spider mite Oligonychus yothersi on Vitis vinifera leaves and we also investigate the sex ratio of this species under laboratory conditions. To access the aspects regarding reproduction, females were placed individually in arenas made of V. vinifera leaves to oviposit and all progeny were mounted on slides when they reached adulthood to confirm the offspring sex.

Population fluctuation of predatory and sanitary importance mites (Acari) in commercial laying hens: Ecological interactions.

This study aimed to evaluate the mite fauna and their ecological interactions in commercial laying hen farms in the state of Rio Grande do Sul, Brazil. It was conducted from August 2013 through August 2014 with two sampling strategies (feathers and traps) in three different production systems: automated (A), semi-automated (S) and free-range (FR). A total of 38,383 mites were collected belonging to 23 families and 33 species, most of which were collected in feathers (74%) followed by traps (26%).

Ectoparasitism of commercial laying hen by Megninia ginglymura (Mégnin) (Acari): population dynamic and distribution on the body regions.

Ectoparasites are temporary or permanent skin dwellers. Megninia ginglymura (Mégnin) (Analgidae) causes economic damage in commercial poultry farms as a result of lower egg production or even death of the host. Little is known about Megninia ginglymura's life cycle and infestation.

Two new genera of pyroglyphid mites, and , with a key to genera of the World (Acari: Pyroglyphidae).

We describe Tuccioglyphus setosus gen. et sp. nov.

Influence of laying hen systems on the mite fauna (Acari) community of commercial poultry farms in southern Brazil.

Intensive production of confined laying hens affects their welfare and increases the risk of epidemics. Ectoparasites as hematophagous and feather mites cause low productivity and decreased egg quality. This study aimed to determine the diversity of mites captured with traps in different commercial systems of laying hens (Gallus gallus L.
