Abstract The dispersal pattern of the widow spider Latrodectus hasseltii (Araneae: Theridiadae), in Osaka Prefecture, Japan, was analyzed from accumulated survey data of spider distribution. [...] Key Method All confirmed infested points from 1996 to 2002 were plotted on a map, and infested points in each survey year were connected with the nearest previously confirmed points.Expand
Invasion of the redback spider Latrodectus hasseltii (Araneae: Theridiidae) into human-modified sand dune ecosystems in Japan
This is the first report of the invasion of the exotic redback spider Latrodectus hasseltii into semi-natural habitats in Japan, and results suggest that L. hasselTii poses a threat to the conservation of coastal insects inhabiting human-modified sand dune ecosystems. Expand
The Occurrence of Red-Back Spider Latrodectus hasselti (Araneae: Theridiidae) in Bandar Abbas, Southern Part of Iran
The red-back spider, L. hasselti, had specific morphological characters including black color with an obvious orange to red longitudinal strip on its upper parts of abdomen and since the region is an important harbor and port and goods come form different parts of world the authors assume the possibility of arrival from its origin and native breeding sites of the world.

The invasive Australian redback spider, Latrodectus hasseltii Thorell 1870 (Araneae: Theridiidae): current and potential distributions, and likely impacts
The presence of L. hasseltii in New Zealand and Japan, and its possible spread to other areas, is of human health significance, and the species may also impact on native biodiversity. Expand
Invasive redback spiders (Latrodectus hasseltii) threaten an endangered, endemic New Zealand beetle (Prodontria lewisii)
An estimated redback population of between 208 and 371 spiders is estimated, with maximum web densities ranging between 8.7 and 10.7 webs per hectare within the CCBNR, and the first record of skink predation by redback spiders in New Zealand. Expand
First record of Red-Back Spider Latrodectus hasselti Thorell ,1870(Araneae:Theridiidae) from Basrah, South of Iraq
The Red-back spider Latrodectus hasselti Thorell,1870 is reported from temperate and tropical zone throughout the world, but for the first time from Safwan area, Basrah, South of Iraq is reported. Expand
Differences in Bifenthrin and Fipronil Susceptibility Among Invasive Latrodectus spp. (Araneae: Theridiidae) and Nontarget Spiders in Japan
Chemical operations aimed at the effective population management and subsequent eradication of invasive Latrodectus spiders while supporting local biodiversity conservation would benefit from considerations of fipronil dosages and target species sensitivities. Expand
Investigation of two new putative pheromone components of the invasive Australian redback spider, Latrodectus hasseltii, with potential applications for control
The identification of butyric acid as a component of the airborne sex pheromone of L. hasseltii provides the groundwork for developing a phersomone-based control of the Australian redback spider. Expand
Application of GIS in the analysis of distribution of medically important arthropods and related diseases
The distribution of medically important arthropods and related diseases is changing on a global scale due to issues involving natural environments, socioeconomic conditions and border disputes, etc.Expand
Competitive interactions between a native spider (Frontinella communis, Araneae: Linyphiidae) and an invasive spider (Linyphia triangularis, Araneae: Linyphiidae)
The effect of the European hammock spider Linyphia triangularis (Araneae, Linyphiidae) on the native bowl-and-doily spider Frontinella communis in Acadia National Park, Maine, USA is examined. Expand
Synergy between two invasive species, redback spiders and rabbits, threaten the endangered Cromwell chafer beetle
It is shown that introduced European rabbits create habitat that enables invasive redback spiders to establish and prey upon the nationally endangered, endemic Cromwell chafer beetle. Expand


Gene flow among habitat patches on a fragmented landscape in the spider Argiope trifasciata (Araneae: Araneidae)
Level of genetic variability and gene flow among seven populations in central Pennsylvania, based on variation at eight allozyme loci, suggests that ballooning may be a far less effective means of long-distance dispersal than previously thought. Expand
Selection of Habitat by the Spider Argiope aurantia Lucas (Araneidae)
Visual search for the webs and egg sacs of Argiope aurantia Lucas showed that it is most abundant in dense perennial vegetation, and it is suggested that wind reduction is the significant stimulus to immatures, and light, to adults. Expand
The Experimental Analysis of Competition between Two Syntopic Species of Orb-Web Spiders (Araneae: Araneidae)
Observed field experiments in 1979 and 1980 provide indirect evidence of the importance of physical factors and possibly vegetation in the distribution and abundance of A. au- rantia and A. trifasciata. Expand
Animal habitat isolation by roads and agricultural fields
Abstract Natural areas are continuously disappearing. Surviving patches resemble islands in terms of limited area, isolation and distance from each other. Road construction and agriculturalExpand
Survey of 2144 Cases of Red‐Back Spider Bites: Australia and New Zealand, 1963‐1976
An analysis has been made of 2144 consecutive cases of latrodectism (envenomation by the redback spider, Latrodectus mactans hasselti) reported to the Commonwealth Serum Laboratories, finding local pain, redness and swelling were the most common symptoms. Expand
Black and brown widow spider bites in South Africa. A series of 45 cases
It was evident that black widow spider bites caused a more severe form of envenomation than brown widow bites, characterised by generalised muscle pain and cramps, abdominal muscle rigidity, profuse sweating, raised blood pressure and tachycardia. Expand

Purification from black widow spider venom of a protein factor causing the depletion of synaptic vesicles at neuromuscular junctions
A protein fraction was obtained that caused a great increase in the frequency of occurrence of miniature end plate potentials at the frog neuromuscular junction, and caused swelling of the nerve terminals and depleted them of their vesicles. Expand
