An ongoing project examines sterile insect technique as a tool for area-wide IPM for navel orangeworm (NOW). This project offers the possibility of providing insects for mark-release-recapture experiments to improve mating disruption and monitoring. Improved vigor of field-released NOW would be useful to obtaining these side benefits, as well as for optimizing. Current efforts involve use of alternating thermoperiods in rearing. This allows prevention of mating in the first scotophase following emergence, separation by sex, and may improve tolerance of the cold stress that is frequently involved in collecting insectary-reared moths and transporting them to the field. Results of this research will be discussed.
