Neoseiulus Hughes is one of the most diverse genus Phytoseiidae, with approximately 400 described species. Among them, tunus (De Leon) very frequent and abundant in Neotropical region. Although considerable amount data about morphological variation phytoseiid mites are available, possible causes intraspecific variations still poorly understood, being diet feeding habit usually reported as main ...

A new species of eriophyoid mite from Australia is described and illustrated. Aceria thalgi sp. n. causes severe curling and rolling of leaves of common introduced sowthistle, Sonchus oleraceus L. It also affects introduced Sonchus asper (L.) Hill and native Sonchus hydrophilus Boulos. The native species may be the original host for this mite. Aceria thalgi sp. n. is shown to be a separate spec...

Confocal laser scanning microscopy (CLSM) is a modern powerful technique that can be used for studying the external and internal anatomy of arthropods. CLSM has seldom been used in acarology and very rarely for studying eriophyoid mites. It allows the capture of precise digital images of the fine details of external and internal chitinous structures, which can be further analysed using various ...

Two iolinid predatory mites were studied in the laboratory as potential biological control agents of tomato russet mite, Aculops lycopersici (Acari: Eriophyidae). The development, reproduction and predation capacity Pronematus ubiquitus Homeopronematus anconai Iolinidae) on A. investigated. Developmental time from egg to adult at 25 °C averaged 9.59, 9.31 9.52 days for P. lycopersici, Typha ang...

This study determined the main mite species on rubber trees (clone RRIM-600) in Piracicaba, southeast of São Paulo State, from June 2002 to May 2003 and evaluated the possible relation between them. It was conducted in a plantation of 5 ha on 11 year old trees, 15 m high, surrounded with crops as pearl millet, cotton, bean or corn. Samples were taken monthly and consisted of five leaflets, five...

Interest in studying galls and their arthropods inducers has been growing rapidly in the last two decades. However, the Neotropical region is probably the least studied region for gall-inducing arthropods. A study of the richness and composition of gall-inducing arthropods was carried out at Coiba National Park in the Republic of Panama. Field data come from samples obtained between August 1997...

The combined impact of multiple plant parasites on plant performance can either be additive (the total damage equals the sum of the individual effects) or nonadditive (synergistic or antagonistic damage). Two statistical models are available for testing the independent (=additive) effects of two factors. Here we suggest that the natural history of the plant-parasite system should motivate the c...
