Two new species of the genus Ologamasus (Ologamasidae) from apple orchards in southern Brazil.

This paper describes two new species of the genus Ologamasus (Acari: Ologamasidae), namely Ologamasus margaridae n. sp. and Ologamasus tuberculatus n.

Acarofauna associated with organic matter in laying aviaries of different rearing systems in Brazil.

Due to the high density of chickens housed within the same space in aviaries, a large volume of organic matter accumulates on the floor. This large supply of available resources allows the development of arthropods, including organisms that affect poultry productivity and health. This study aimed to evaluate the composition of the mite community associated with organic matter in poultry houses with different rearing systems and the verification of potential predators to be evaluated in clean management techniques, such as biological control.

Two new species of Tydeidae (Acari: Prostigmata) associated with stingless bees.

Tydeid mites have a cosmopolitan distribution and are associated with diverse substrates such as soil, plants, stored products, and animals like vertebrates and insects. Here we report two new species of tydeid mites living inside stingless bee colonies in Brazil. Lorryia meliponarum n.
