  • Pheromonostatic peptide used to disrupt mating of the corn earworm, helicoverpa zea
    Patent number: 5344821
    Abstract: A polypeptide having the property of rendering a female Helicoverpa zea moth non-receptive to mating was isolated from the reproductive tract of the male moth. The peptide is transferred from the male to the female during mating and causes a depletion of the female sex pheromone thereby resulting in a decline in sexual attractiveness for at least 24 hours.The peptide is referred to as pheromonostatic peptide, or PSP. It is a basic peptide having 57 amino acid residues, a molecular weight of 6617 daltons and contains one pair of cysteine residues in a disulfide linkage.
