MICROSPORIDIA INFECTING BENEFICIAL INSECTS WHICH SERVE AS BIOLOGICAL CONTROL AGENTS
Resumo
This review presents up-to-date data on microsporidian infections in beneficial insects used to control agricultural pests. Among these biocontrol agents, microsporidia have been reported predominantly from hymenopteran parasitoids and predatory insects belonging to various orders, mainly Holometabola. Parasitoids can be infected by pathogens specific for their hosts or bear their own parasites. Infections with microsporidia may cause serious pathologic changes or remain benign, while still affecting population dynamics of the insect pests against which the biocontrol agents are applied.

MOLECULAR CHARACTERIZATION OF SRIVASTAVANEMA SP. FROM VIETNAMESE HAIRY-FOOTED FLYING SQUIRRELS BELOMYS PEARSONII (GRAY, 1842)
Resumo
Heligmonellidae is a family of parasitic nematodes that includes parasites of tropical and subtropical mammals. Flying squirrels (Pteromyini, Sciuridae) are one of the characteristic hosts of heligmonellid nematodes. The nematodes of the genus Srivastavanema were collected from the flying squirrel Belomys pearsonii during a zoological expedition of the Joint Russian-Vietnamese Center for Tropical Research and Technology. Morphological study of the nematodes was carried out using optical and scanning electron microscopy. Partial sequences of 28S rRNA gene and ITS2 region were also obtained. Phylogenetic analysis based on 28S rRNA revealed related forms within Mexican rodent parasites. Further analysis of the molecular phylogeny with the inclusion of other loci is necessary to resolve the current controversy between classifications based on molecular and morphological data.
