Increasing losses to the navel orange-worm, Paramyelois transitella (Walker), have led to a multi-disciplinary research program to find better methods of controlling this primary pest of almonds in California. One result of this research was the development of a new method for monitoring navel orangeworm (NOW) moth activity. The device used-an “egg trap”—enables growers, field men, and researchers to monitor female moth flights and egg-laying (oviposition) activity directly, rather than monitoring the flight of male moths, as when using sex pheromone traps.
