A new microsporidian pathogen, Vairimorpha gastrophysae sp. nov., isolated from Gastrophysa viridula (Coleoptera: Chrysomelidae).

Gastrophysa viridula DeGeer 1775, the green dock leaf beetle, belongs to a group of beneficial insects, which can be used as a classical biological control agent against sorrels (Rumex sp., Polygonaceae). Therefore, any infection by pathogenic organisms in this beetle is undesirable.

A microsporidian pathogen of the predatory beetle Rhizophagus grandis (Coleoptera: Rhizophagidae).

A new Microsporidium sp. infects Rhizophagus grandis Gyllenhall, a beetle which preys on the bark beetle Dendroctonus micans Kugellan in Turkey. Mature spores are single, uninucleate, oval in shape (3.

First record of the insect pathogenic alga Helicosporidium sp. (Chlorophyta: Trebouxiophyceae) infection in larvae and pupae of Rhizophagusgrandis Gyll. (Coleoptera, Rhizophaginae) from Turkey.

The predator beetle Rhizophagus grandis Gyll. (Coleoptera, Rhizophaginae) is one of the most important biological control agents, mass-bred and used to suppress populations of an important pest: the great spruce bark beetle, Dendroctonus micans. The achlorophyllous alga Helicosporidium sp.

Distribution of Nosema phyllotretae (Microspora, Nosematidae) Weiser, 1961 in populations of Phyllotreta atra (Coleoptera, Chrysomelidae) in Turkey.

The distribution of Nosema phyllotretae infection of Phyllotreta atra populations in Turkey is reported for the first time. In total, 48 of the 1668 beetles from 24 samples collected in five localities were infected by the parasite. Nosema infection was found in P.
