Abstract
Regurgitates of the grasshopper Schistocerca americana were deterrent to Crematogaster ants. Regurgitates obtained from insects fed upon wheat seedlings were more strongly deterrent than those obtained from insects fed on romaine lettuce leaves. After extraction of the regurgitates with ethyl acetate, deterrence could be demonstrated in both the organic and aqueous phases. Wheat seedlings, lettuce, and feces from wheat- or lettuce-fed insects yielded extracts with lower deterrency. Our results suggest that deterrents in the organic phase of the regurgitate are primarily due to the presence of plant natural products, whereas the deterrency of the aqueous phase is probably due to digestive enzymes from enteric components, probably digestive enzymes.
