The Schoeman2 survey was carried out between 1999 and 2007, and consisted of five intensive surveys between Affiliations: two and 12 days in duration. Arachnids were sampled in five broad habitat types, namely fynbos, 1Department of Zoology & wetlands, i.e. De Hoop Vlei, Eucalyptus plantations at Potberg and Cupido’s Kraal, coastal dunes Entomology University of near Koppie Alleen and the intertidal zone at Koppie Alleen. A total of 274 species representing the Free State, five orders, 65 families and 191 determined genera were collected, of which spiders (Araneae) South Africa were the dominant taxon (252 spp., 174 genera, 53 families).

Effects of Removal Or Reduced Density of the Malaria Mosquito, Anopheles
Medical and Veterinary Entomology (2018), doi: 10.1111/mve.12327 REVIEW ARTICLE Effects of the removal or reduction in density of the malaria mosquito, Anopheles gambiae s.l., on interacting predators and competitors in local ecosystems C. M. COLLINS1 , J. A. S. BONDS2, M. M. QUINLAN1 and J. D. MUMFORD1 1Centre for Environmental Policy, Imperial College London, London, U.K. and 2Bonds Consulting Group LLC, Panama City Beach, Florida, U.S.A. Abstract. New genetic control methods for mosquitoes may reduce vector species without direct effects on other species or the physical environment common with insecticides or drainage. Effects on predators and competitors could, however, be a concern as Anopheles gambiae s.l. is preyed upon in all life stages. We overview the literature and assess the strength of the ecological interactions identified. Most predators identified consume many other insect species and there is no evidence that anyspecies preys exclusively on any anopheline mosquito. There is one predatory species with a specialisation on blood-fed mosquitoes including An. gambiae s.l.. Evarcha culicivora is a jumping spider, known as the vampire spider, found around Lake Victoria. There is no evidence that these salticids require Anopheles mosquitoes and will readily consume blood-fed Culex. Interspecific competition studies focus on other mosquitoes of larval habitats. Many of these take place in artificial cosms and give contrasting results to semi-field studies. This may limit their extrapolation regarding the potential impact of reduced An. gambiae numbers. Previous mosquito control interventions are informative and identify competitive release and niche opportunism; so while the identity and relative abundance of the species present may change, the biomass available to predators may not. -

Evarcha culicivora, an East African jumping spider, is known for feeding indirectly on vertebrate blood by actively choosing blood-carrying mosquitoes as prey. Using cold-anthrone tests to detect fructose, we demonstrate that E. culicivora also feeds on nectar. Field-collected individuals, found on the plant Lantana camara, tested positive for plant sugar (fructose). In the laboratory, E. culicivora tested positive for fructose after being kept with L. camara or one of another ten plant species (Aloe vera, Clerodendron magnifica, Hamelia patens, Lantana montevideo, Leonotis nepetaefolia, Parthenium hysterophorus, Ricinus communis, Senna didymobotrya, Striga asiatica,andVerbena trivernia). Our findings demonstrate that E. culicivora acquires fructose from its natural diet and can ingest fructose directly from plant nectaries. -
Jumping Spiders That Love Smelly Socks Could Help Fight Malaria 17 February 2011, by Lin Edwards
Jumping spiders that love smelly socks could help fight malaria 17 February 2011, by Lin Edwards small holding chamber connected to an exit chamber and pumped air into the holding chamber from one of two boxes. One of the boxes contained a clean sock, and the other contained a smelly sock that had been worn for 12 hours. The spider was free to move into the exit chamber at any time, and this chamber had normal, unscented air. The results of the experiment were that the spiders stayed in the holding chamber 15 to 30 minutes longer if their air was laden with the scent of smelly socks than if the air carried the clean sock smell.

Mosquitoes Supply Spider with Blood 11 October 2005
Mosquitoes supply spider with blood 11 October 2005 Scientists in Sydney, Australia, say they've determined an East African species of jumping spider prefers to prey on blood-engorged female mosquitoes. And that, the Macquarie University researchers said, demonstrates a rare example of a predator choosing its prey based on what the prey has eaten. Evarcha culicivora, a type of mosquito-eating spider, lives near Lake Victoria in Kenya and Uganda. As with all other spiders, these spiders lack the specialized blood-sucking body parts that mosquitoes and ticks possess and thus cannot feed directly on animal blood. Ximena Nelson and colleagues studied E. culicivora and found the spiders consistently choose to eat female mosquitoes that had recently fed on vertebrate blood. The spiders preferred the mosquitoes to other prey such as midges, male mosquitoes, and sugar-fed female mosquitoes. The researchers said the spiders identified their preferred prey by sight and smell. Those preferences appear to be innate, and not due to other factors such as prior experience or prey availability, the researchers say. Further work suggests the blood-meal is biologically important to E. culicivora. The study appears in the online early edition of the Proceedings of the National Academy of Sciences.
