Parasitology Research, 2023 An ant-pathogenic neogregarine in Temnothorax affinis and T. parvulus (Hymenoptera: Formicidae) is described based on morphological and ultrastructural characteristics. The pathogen infects the hypodermis of the ants. The infection was mainly synchronous so that only gametocysts and oocysts could be observed simultaneously in the host body.

The flagellate Crithidia bombi and the neogregarine Apicystis bombi have been found in individuals of Bombus terrestris, a Palaearctic species of bumble bee commercially reared and shipped worldwide for pollination services. B. terrestris has recently entered into the northwestern Patagonia region of Argentina from Chile, where it was introduced in ...

Acta Parasitologica, 2012 AbstractThis study concerns a new neogregarine parasitic in the great spruce bark beetle Dendroctonus micans (Kugelann) (Curculionidae, Scolytinae). The rate of infection was high, reaching 27.3%. There was no difference in the rate of infection of male and female beetles.

Parasitology Research, 2015 A new neogregarine pathogen of the great spruce bark beetle, Dendroctonus micans (Coleoptera: Curculionidae, Scolytinae), is described based on light microscopy and ultrastructural characteristics. The pathogen infects the fat body and the hemolymph of the beetle. The infection was nonsynchronous so that different developmental stages could be observed

A neogregarine parasite of the red imported fire ant, Solenopsis invicta, was discovered recently in Florida and tentatively placed in the Mattesia genus based on morphological characterization. S. invicta infected with this Mattesia species exhibited a characteristic yellowing of the cuticle which was designated Mattesia "yellow-head disease" (YHD ...

Throughout their global range, wild monarch butterflies (Danaus plexippus) are infected with the protozoan Ophryocystis elektroscirrha (OE). In monarchs, OE infection reduces pupal eclosion, adult lifespan, adult body size and flight ability. Infection of other butterfly hosts with OE is rare or unknown, and the only previously published records of OE ...

A newly recorded neogregarine (Protozoa, Apicomplexa), parasite in honey bees (Apis mellifera) and bumble bees (Bombus spp) [PDF]
Apidologie, 1992 L'examen au microscope de tissus d'adultes d'Apis mellifera, recoltes en 1990 en Finlande, et de Bombus terrestris et de B hortorum, recoltes en 1988 en Italie, a montre la presence de spores d'un protozoaire encore inconnu. D'apres le cycle de developpement du parasite, etudie sur des frottis du corps gras fixes 2 min au methanol et colores avec une ...

Studies on the Life History of a Neogregarine Parasite Found in Leptothorax Ants from North America
Biocontrol Science and Technology, 1997Pupal stages of Leptothorax ants collected near West Yellowstone, MT, USA, displayed striking signs and symptoms of disease, i.e., grey to black coloration, irregular pigmentation of compound eyes and toothless mandibles. Light microscope studies revealed heavy infections by a neogregarine, the life history of which is described.

Abstract During a 4-year study on a hill country (Waikato, New Zealand) population of endemic sod webworms ( Eudonia sabulosella ) an initially dense and pasture damaging population was severely reduced by attack from a neogregarine protozoan ( Mattesia sp.). Disease prevalence increased from 1978 to 1981. Larvae and adults infected by Mattesia sp.
