Spider venoms are usually toxic when injected into prey, but a new protein discovered in the venom of Australian tarantulas can also kill prey insects that consume the venom orally. The protein is strongly insecticidal to the cotton bollworm, an important agricultural pest, according to research published September 11 in the open access journal PLOS ONE by Glenn King and Maggie Hardy from the Institute of Molecular Bioscience at the University of Queensland, Australia, and colleagues from other institutions.

The small protein, named orally active insecticidal peptide-1 (OAIP-1), was found to be highly toxic to insects that consumed it, with potency similar to that of the synthetic insecticide imidacloprid. Cotton bollworm, a pest that attacks crop plants, was more sensitive to OAIP-1 than termites and mealworms, which attack stored grains.
