Spider-Venom Peptides as Bioinsecticides [PDF]
Toxins, 2012 Over 10,000 arthropod species are currently considered to be pest organisms. They are estimated to contribute to the destruction of ~14% of the world’s annual crop production and transmit many pathogens. Presently, arthropod pests of agricultural and health significance are controlled predominantly through the use of chemical insecticides ...

Venomous spiders of Albania –does an increase of temperature influence the toxicity of spider venom?
Toxicon: X, 2022 Black widow spiders (Latrodectus sp.) are distributed worldwide, and in Albania the L. tredecimguttatus Rossi, 1790 has been the dominant spider. Other medically important spiders in Albania include the brown recluse with symptoms known as loxoscelism, the false black widow and the egg sac spiders; the last two inducing similar symptoms to a wasp sting.

Main Components of Spider Venoms [PDF]
, 2013 Venom glands are alreadypresent in theoldes t spider group, the Mesothelae. Theglands lie in the anterior portion of the cheliceral basal segment but are very small, and it is doubtful how much the venom contributes to the predatory success.

The deep-rooted origin of disulfide-rich spider venom toxins
eLife, 2023 Spider venoms are a complex concoction of enzymes, polyamines, inorganic salts, and disulfide-rich peptides (DRPs). Although DRPs are widely distributed and abundant, their bevolutionary origin has remained elusive.

Can we resolve the taxonomic bias in spider venom research?
Toxicon: X, 2019 The rate of discovery of new spider species greatly exceeds the rate of spider venom characterisation, leading to an increasing number of species with unstudied venoms.

Toxin diversity revealed by a transcriptomic study of Ornithoctonus huwena. [PDF]
PLoS ONE, 2014 Spider venom comprises a mixture of compounds with diverse biological activities, which are used to capture prey and defend against predators. The peptide components bind a broad range of cellular targets with high affinity and selectivity, and appear to

Brown Spider (Loxosceles genus) Venom Toxins: Tools for Biological Purposes
Toxins, 2011 Venomous animals use their venoms as tools for defense or predation. These venoms are complex mixtures, mainly enriched of proteic toxins or peptides with several, and different, biological activities.
