Composition, abundance and pest control potential of spider communities in agroecosystems: a comparison of European and US studies
PREY SELECTION OF SPIDERS IN THE FIELD
- M. Nyffeler
There seems to be a consistent trend of greater diet breadth of the hunters compared to the web-weavers in agroecosystems, and diet breadth computed with the Inverted Simpson Index was, on average, significantly higher in the hunting spiders than the web spiders.
How Spiders Make a Living
An overview of the feeding patterns of 10 groups of common agroecosystem spiders is presented to inform entomologists and ecologists concerned with issues of natural biological control.
Predation by green lynx spider, Peucetia viridans (Araneae: Oxyopidae), inhabiting cotton and woolly croton plants in East Texas
Predation by green lynx spider, Peucetia viridans (Hentz), was studied on cotton and woolly croton plants in East Texas. This species feeds both diurnally and nocturnally. P. viridans was observed…
Bat Predation by Spiders
Evidence suggests that spider predation on flying vertebrates is more widespread than previously assumed.
Diets, feeding specialization, and predatory role of two lynx spiders, Oxyopes salticus and Peucetia viridans (Araneae: Oxyopidae), in a Texas cotton agroecosystem
The predation ecology of the striped lynx spider, Oxyopes salticus Hentz, and green lynx spider, Peucetia viridans (Hentz), was studied during 108 h of visual observation in an insecticide-free…
An estimated 400–800 million tons of prey are annually killed by the global spider community
The presented estimates of the global annual prey kill and the relative contribution of spider predation in different biomes improve the general understanding of spider ecology and provide a first assessment of theglobal impact of this very important predator group.
Comparison of the Feeding Niche of Polyphagous Insectivores (Araneae) in a Texas Cotton Plantation: Estimates of Niche Breadth and Overlap
The nonweb-building spider Oxyopes salticus Hentz, which actively searches the cotton plant for prey, showed the highest diet breadth value (broad feeding niche) under the conditions of this experiment, which indicates considerable differences between species in feeding specialization.
Evaluation of the Importance of the Striped Lynx Spider, Oxyopes salticus (Araneae: Oxyopidae), as a Predator in Texas Cotton
Predation by the striped lynx spider, Oxyopes salticus Hentz, on cotton arthropods was studied in an unsprayed field in east Texas to estimate how many prey may have been killed by the spider in the middle of the growing season.
