It has been established that 20 species (including two complexes) of freshwater gastropods from 7 families live in water bodies on the territory PSRER, which 51 trematodes 21 with a predominance Echinostomatidae family (10 species) parasitize at parthenitis stage. The maximum number trematode was registered mollusks Lithoglyphus naticoides and Planorbarius corneus – 8 parasites an infestation 1...

Abstract Telenomus remus (Hymenoptera: Scelionidae), is an endoparasitoid on eggs of Spodoptera frugiperda (J. E. Smith). S. . The information T. as a natural enemy very limited. research objective to determine some biological aspects , i.e. longevity, fecundity, and life table variables. demographic statistics using the jackknife method. collected from field identified immature stage reached 8...

Endoparasitoids of arthropods evoke host cellular immune responses that result in hemocytic encapsulation of the endoparasitoid, unless these responses are disrupted by the parasite. Our interest has focused on mutualistic viruses found in some hymenopteran endoparasitoids that disrupt hemocyte function and prevent encapsulation. Specifically, the Campoletis sonorensis polydnavirus interacts wi...

Murine Kupffer cells (KC) were isolated by a high yield collagenase perfusion technique. The morphology, surface markers, and secretory products were typical of macrophages in other tissues. However, KC released negligible levels of H2O2 and O-2, in contrast to peritoneal macrophages. KC oxygen consumption was not increased by agents triggering a respiratory burst in peritoneal cells. Moreover,...
