Oviposition Pheromone in Larval Mandibular Glands of Ephestia kuehniella

Abstract

WHEN larvae of Ephestia kuehniella Zeller meet they deposit from their mandibular glands a pheromone that mediates a response to crowding1. In this communication I show that ovipositing female moths of E. kuehniella respond to the same secretion in such a way that the number of eggs they lay is related to the amount of the larval pheromone (and so to the density of the population of larvae) at the oviposition site.
