The document describes a study that aimed to produce and test the oral activity of a fusion protein combining the spider venom neurotoxin Hv1a and a carrier protein A. The fusion protein Hv1a/A was produced using recombinant technologies in yeast and purified. Droplet feeding assays on lepidopteran larvae found the protein present in the guts and blood 24 hours after oral delivery, demonstrating the fusion protein's ability to be transported into the insects. Testing will continue to evaluate the fusion protein's efficacy and transport of other toxin-carrier combinations.
