Abstract

Abstract Protein, glycogen, and lipid concentrations were followed in Solenopsis invicta queens, the imported fire ant, from egg deposition until the production of the first minim workers approximately 21 days later. During this time, the weight of the queens decreased from 14·7 to 7·5 mg. Immediately following egg deposition, total protein decreased by over 50 per cent for the first 6 days, then rose steadily for 9 days, then once again decreased markedly throughout the remainder of the study. Glycogen concentrations decreased rapidly from the 0·35 mg/ant found at oviposition until day 12. From this time until the end of the study, this polysaccharide remained constant at about 10 mg/ant. Lipid concentrations remained at 4·1 mg/ant for the first 9 days following oviposition, then steadily decreased to 2·3 mg/ant when the first minim workers were produced 12 days later.
