The smaller brown planthopper, Laodelphax striatellus, was reared on holidic diets(MED-1) deficient in single amino acids in order to discern the essential amino acid requirements for the grown of this planthopper. Rearing on a diet lacking cysteine or methionine resulted in death during the middle stage of nymphal development. Dietary deficiency of any one of the remaining 21 amino acids did not prevent the planthoppers from completing nymphal development. The planthoppers, however, diet at the first inster when these amino acids were deleted all together. Cysteine weas thought to be utilized by being converted to cysteine, and its minimum concentration for allowing growth was estimated as 5 mg per 100 ml.When cystine was used instead of cysteine, is minimum effective concecntration was 10 mg per 100ml. The minimum effective concentration of methionine was found to be 40 ng per 100 ml.
