Cricket bioassay results

Caption: Results of invertebrate toxicity assays, evaluating toxin activity using the righting response of immature crickets to each venom fraction. 3 µL of one of the 14 chemical fractions was injected ventrally into the pronotum of an immature cricket, which was then rolled onto its back every 10 seconds 18 times for a total of 3 minutes. A compromised righting response was recorded when a cricket was unable to right itself within 60 seconds of being rolled onto its dorsal side. Each fraction was replicated with 10 crickets.
