Notizen: Abstract Four species of Acridoidea were fed on wheat leaves with and without the condensed tannin, quebracho. In no case was it deleterious to survival and growth at levels below about 10% dry weight on the food. Similarly, consumption, digestibility, and utilization of food were unaffected at up to 10% dry weight. At higher concentrations, however, the consumption and the efficiency of conversion of digestion were reduced, although digestibility was little affected. The possible mechanisms for such tolerance are discussed, and contrast made with insects which are very sensitive to ingested condensed tannin.
