Figure 3From: A fusion protein containing a lepidopteran-specific toxin from the South Indian red scorpion (Mesobuthus tamulus) and snowdrop lectin shows oral toxicity to target insectsSurvival of L. oleracea larvae following injection of purified recombinant proteins. Survival was recorded for fifth stadium L. oleracea larvae following injections of recombinant GNA or ButaIT/GNA. Control insects were injected with phosphate buffered saline (PBS; n = 40). GNA was injected at a dose of 20 μg which equates to approx. 500 μg GNA/g insect (n = 20); ButaIT/GNA was injected at two different concentrations; 4 μg which equates to approx. 100 μg fusion protein or 30 μg toxin/g insect (n = 25), and 20 μg which equates to approx. 450 μg of fusion protein or 135 μg toxin/g insect (n = 10).Back to article page
