Adults of beet webworm Loxostege sticticalis were collected in Western Siberia in 2009 and 2010. A microsporidium was found infecting 12 of 50 moths in 2010. The parasite develops in direct contact with host cell cytoplasm, sporogony is presumably disporoblastic. The spores are ovoid, diplokaryotic, 4.2 × 2.4 μm in size (fresh), without a sporophorous vesicle. Electron microscopy showed: (a) tubules on the surface of sporoblasts and immature spores; (b) slightly anisofilar polar tube with 10-14 coils, last 2-3 coils of lesser electron density; (c) bipartite polaroplast with anterior and posterior parts composed of thin and thick lamellae, respectively; (d) an indentation in the region of the anchoring disc; (e) an additional layer of electron-dense amorphous matter on the exospore surface. The spore ultrastructure is characteristic of the genus Tubulinosema. Sequencing of small subunit and large subunit ribosomal RNA genes showed 98-99.6% similarity of this parasite to the Tubulinosema species available on Genbank. A new species Tubulinosema loxostegi sp. n. is established.

Considerable research efforts have been made to predict the influences of climate change on species composition in biological communities. However, little is known about how changing environmental conditions and anthropogenic pollution can affect aquatic communities in combination. We investigated the influence of short warming periods on the response of a zooplankton community to the insecticide esfenvalerate at a range of environmentally realistic concentrations (0.03, 0.3 and 3 μg L-1) in 55 outdoor pond microcosms. Warming periods increased the cumulative water temperature, but did not exceed the maximum temperature measured under ambient conditions. Under warming conditions alone the abundance of some zooplankton taxa increased selectively compared to ambient conditions. This resulted in a shift in the community composition that had not recovered by the end of the experiment, 8 weeks after the last warming period. Regarding the pesticide exposure, short-term effects of esfenvalerate on the community structure and the sensitive taxa Daphnia spp. did not differ between the two temperature regimes. In contrast, long-term effects of esfenvalerate on Daphnia spp., a taxon that did not benefit from elevated temperatures, were observed twice as long under warming than under ambient conditions. This resulted in long-term effects on Daphnia spp. until 4 months after contamination at 3 μg L-1 esfenvalerate. Under both temperature regimes, we identified strength of interspecific competition as the mechanism determining the time until recovery. However, enhanced interspecific competition under warming conditions was prolonged and explained the delayed recovery of Daphnia spp. from esfenvalerate. These results show that, for realistic prediction of the combined effects of changing environmental factors and toxicants on sensitive taxa, the impacts of stressors on the biotic interactions within the community need to be considered. © 2013 Blackwell Publishing Ltd.

Ecotoxicology | Year: 2012

Xenobiotics alter the balance of competition between species and induce shifts in community composition. However, little is known about how these alterations affect the recovery of sensitive taxa. We exposed zooplankton communities to esfenvalerate (0.03, 0.3, and 3 μg/L) in outdoor microcosms and investigated the longterm effects on populations of Daphnia spp. To cover a broad and realistic range of environmental conditions, we established 96 microcosms with different treatments of shading and periodic harvesting. Populations of Daphnia spp. decreased in abundance for more than 8 weeks after contamination at 0.3 and 3 μg/L esfenvalerate. The period required for recovery at 0.3 and 3 μg/L was more than eight and three times longer, respectively, than the recovery period that was predicted on the basis of the life cycle of Daphnia spp. without considering the environmental context. We found that the recovery of sensitive Daphnia spp. populations depended on the initial pesticide survival and the related increase of less sensitive, competing taxa. We assert that this increase in the abundance of competing species, as well as sub-lethal effects of esfenvalerate, caused the unexpectedly prolonged effects of esfenvalerate on populations of Daphnia spp. We conclude that assessing biotic interactions is essential to understand and hence predict the effects and recovery from toxicant stress in communities. © Springer Science+Business Media, LLC 2012.

Entomological Review | Year: 2011

The basic features of spatial differentiation of ant communities were studied based on quantitative counts in all the landscapes of Central Altai. Gradual changes in the structure of ant communities on altitudinal belts were observed, as well as the mosaic patterns of the complexes determined by the variations in meso- and microclimatic conditions within the belt. The main trends in the correlated changes of ant communities and environmental factors were revealed. Classification of ant communities which may form the basis for the legend of a medium-scale map was made using multidimensional factor analysis. The specific features of the spatial differentiation of ant communities in Central Altai, as well as those in Northeast Altai studied earlier, are largely determined by fluctuations in the hydrothermal conditions of these regions. Among the anthropogenic factors, the most significant one in both provinces is transformation of habitats caused by plowing, stocking, annual mowing, and construction. © 2011 Pleiades Publishing, Ltd.

This article is based on data obtained in the studies of soil gamasid mites (Mesostigmata) from 24 typical habitats situated along the elevational gradient 400–1860 m above sea level in the northern Altai region. It addresses the changes in the main synecological properties–taxonomic diversity, total abundance, and β-diversity index–among the elevational zones. The distribution of species with different types of habitats along the elevational gradient is analyzed taking the number of species, abundance, and share in the total number and abundance into consideration. The spatial–typologic structure of populations of gamasid mites from northern Altai are found to be heterogenous, and the effect of different ecological factors on it is estimated. © 2015, Pleiades Publishing, Ltd.

Voprosy Virusologii | Year: 2016

Introduction. Insect viruses can play an important role in population dynamics of their hosts. That is why the problem of permanent viral infection support among virus-positive insects is associated with one of the intriguing problems of general biology and virology. Materials and methods. Under laboratory conditions, the modeling of the vertical transmission of the nucleopolyhedrovirus (NPV) gypsy moth was implemented at relatively high level of mortality among insects of parental generation (60%). The diagnostics of the occult virus was executed by the PCR method among insects before their infection under laboratory conditions, as well as among insects that survived after inoculation. Results. The NPV-caused mortality among insects that survived after infection in generations F1, F2, and F3 was 14 ± 4%, 10 ± 4%, and 5 ± 0.5%, respectively. In the following three generations NPV-induced mortality was not noticed. Discussion. The level of the virus-positive individuals among the gypsy moth embryos in all occasions was higher than the NPV-induced mortality of insects. Thus, the given results show that the presence of virus among insect does not mean inevitable mortality of their hosts. Perhaps, the viral DNA can completely or partly lose its infectivity but may exist in the analyzed insect samples. Conclusions. The viral infection can be formed among progeny surviving after inoculation of insects. It can be actuated during three generations of the gypsy moth. The level of the virus-positive individuals among the gypsy moth embryos determined by the PCR method in daughter generations was higher than the NPV-induced mortality of insects.
