Abstract
The invention provides short peptides derived from an insect neuropeptide for controlling insects, particularly peptides or their analogs derived from PBAN family neuropeptide having at least one dPhe residue. The invention further provides an environmentally friendly method for controlling and/or preventing insect infestation by applying the short peptides in very low concentrations.
