Essential Amino Acids in Apis Mellifera Larvae During Floral Dearth

Floral dearth influenced the spectra of larval amino acids of honey bee Apis mellifera. Despite sugar (sucrose) syrup feeding, the essential amino acids were lowest (2) in 5^th instar larvae. Feeding of mahua (Bassia latifolia Roxb.) flower's syrup during lean period increased the amino acids concentration. Larval essential amino acids detected in the mahua syrup treatment include leucine, isoleucine and valine. Methionine was not detected in any sugar treatment, but found in 4^th and 5^th instars when fed with mahua syrup and tryptophan in 2^nd instar Free amino acids of mahua flower, honey and propolis have also been analysed.
