The hobo spider, Tegenaria agrestis, is a member of the family of spiders known as the Agelenidae or funnel web weavers. The first record of Tegenaria agrestis Walckenaer in the United States was in Seattle,Washington in 1930 [1,2]. European distribution is widespread from Europe to central Asia [3].The current range of T. agrestis, originally named the aggressive house spider, includes Washing...

Wolf spider species of the genus Pardosa show a typical stenochronous life cycle, adults reproducing in the spring and different instars of the juvenile stage overwintering (Schaefer, 1977). The life cycle is typically one year long (Tretzel, 1954; Vlijm et al., 1963; Merrett, 1968) in Western and Central Europe, but at more Northern latitudes it can be extended to two (Edgar, 1972; Stepczak, 1...

This study documents the occurrence of an aggressive invasive earthworm species in undisturbed forest soils of the southern Appalachian Mountains of northern Georgia, USA. Earthworms were sorted from samples collected in pitfall traps that had been set in mature, mesic oak-hickory forests in remote, high elevation, locations across northern Georgia. Specimens were continuously collected in thes...

Larvae of Bradysia agrestis, an insect vector that transports plant pathogens, were sampled from geographically isolated regions in Korea to identify their cutaneous fungal and bacterial flora. Sampled areas were chosen within the distribution range of B. agrestis; each site was more than 91 km apart to ensure geographical segregation. We isolated 76 microbial (fungi and bacteria) strains (site...

راب خاکستری مزرعه­ای یکی از آفات مهم سبزیجات در استان­های شمالی کشور است. آنزیم­های گوارشی آفات اهداف بسیار خوبی برای عوامل آفت­کش مانند بازدارنده­ها می­باشد. بازدارنده­های آنزیم­های گوارشی برای تولید گیاهان تراریخته مقاوم به آفات استفاده می­شوند. برای رسیدن به این هدف بایستی ماهیت و ویژگی­های آنزیم­های گوارشی مورد مطالعه قرار گیرد. در این مطالعه ویژگی­های بیوشیمیایی آلفا-گلوکوزیداز و بتا-گلوکو...

On a local scale, invasiveness of introduced species and invasibility of habitats together determine invasion success. A key issue in invasion ecology has been how to quantify the contribution of species invasiveness and habitat invasibility separately. Conventional approaches, such as comparing the differences in traits and/or impacts of species between native and/or invaded ranges, do not det...

To examine the host association of Tula virus (TULV), a hantavirus present in large parts of Europe, we investigated a total of 791 rodents representing 469 Microtus arvalis and 322 Microtus agrestis animals from northeast, northwest, and southeast Germany, including geographical regions with sympatric occurrence of both vole species, for the presence of TULV infections. Based on serological in...

We report a PCR survey of hantavirus infection in an extensive field vole (Microtus agrestis) population present in the Kielder Forest, northern England. A Tatenale virus-like lineage was frequently detected (≈17% prevalence) in liver tissue. Lineages genetically similar to Tatenale virus are likely to be endemic in northern England.

Slug activity is associated with conditions of high humidity, and this association has, not unnaturally, led to the hitherto untested assumption that it was in some way induced by the necessarily damp conditions. The experimental examination of this phenomenon, described in this paper, has shown that certain changes in temperature, and not conditions of high humidity, induce activity. Such temp...
