Changes in the chemical composition of fat body during the last larval instar of Manduca sexta.
The fat body increases in weight throughout the last larval instar in spite of the loss in total body weight during the wandering and prepupal stages. The protein content of fat body increases dramatically and is greatly responsible for the increase in fat body weight in the wandering and prepupal stages. Lipids do not contribute significantly to the fat body weight gain except during the feeding stage. The amount of total fat body RNA increases until wandering then drops abruptly in the prepupal stage. The total amount of fat body DNA peaks before the onset of wandering and prepupal stages.
