Structural studies on lipophorin, an insect lipoprotein.
An insect high density lipoprotein, lipophorin, can be rapidly isolated from larval Manduca sexta (tobacco hornworm) hemolymph by single vertical spin density gradient ultracentrifugation. The twoExpand

Ovarian ecdysone secretion is controlled by a brain hormone in an adult mosquito
In the mosquito Aedes aegypti, a blood meal triggers egg development. Early workers used the simple technique of decapitation, or neck ligation, to show that a factor from the head was required forExpand
