Tropical grasshopper glutathione-S-transferase and detoxification of plant allelochemicals in Calotropis procera
Archives of Phytopathology and Plant Protection 45 (6), 707-711
Abstract: Poecilocerus bufonius inhabits Saudi Arabia and uses Calotropis procera as its main host plant. Cardenolids of this plant are used by this grasshopper as chemical defence against the natural enemies. The activity of enzyme detoxification in mid-gut wall for these allelochemicals has been determined in this study. Results indicate that the activity of glutathione-S-transferase (GST) was significantly higher after 24 hours of feeding on the main host plant but no difference has been found after one, two, four and five hours of feeding.
