Toxicity of the venoms of two scorpions ( Androctonus australis and Centruroides sculpturatus) and a sea anemone ( Condylactis gigantea): Acute and antifeeding actions in the cotton bollworm ( Heliothis zea)

1. Single injections of 12.5–100 μg/larva Androctonus australis and Centruroides sculpturatus scorpion venoms and Condylactis gigantea sea anemone powder decreased larval weight and fecal production of fourth instar Heliothis zea. 2. Although the venoms decreased overall feeding, diet consumption wa...

More Information
Summary:1. Single injections of 12.5–100 μg/larva Androctonus australis and Centruroides sculpturatus scorpion venoms and Condylactis gigantea sea anemone powder decreased larval weight and fecal production of fourth instar Heliothis zea. 2. Although the venoms decreased overall feeding, diet consumption was proportional or increased compared to larval weight. 3. The three compounds increased digestive ability of treated larvae but inhibited conversion of the digested food to biomass; the resulting growth rate of envenomed larvae was significantly decreased.
