The Metabolic Effects of the Corpus Allatum Hormone in the Male Desert Locust : I. Lipid Metabolism
1 Zoological Laboratory Downing Street, Cambridge; Department of Zoology, University College, Nairobi, Kenya
1. An account is given of the normal pattern of total lipid content of male desert locusts from the time of adult emergence to the time the locusts are approaching senescence (18-25 days). Up to the seventh adult day, there is a rapid increase in the amount of body lipids; thereafter, there is a progressive depletion of lipid reserves.
2. Allatectomy of the locusts soon after adult emergence leads to considerable accumulation of lipids which becomes apparent when the locusts attain sexual maturity and persists thereafter. Gonadectomy or mere wounding has no such effects.
3. Implantation of active corpora allata in previously allatectomized locusts reverses the tendency to lipid accumulation.
