Abstract
The subject invention concerns novel peptides which have the property of interfering with the biosynthesis of the enzyme trypsin. This property enables the use of these peptides to, for example, inhibit the formation of progeny in blood-ingesting insects, since trypsin is an essential enzyme for food digestion which provides the essential building blocks for egg development in such insects.
