ABSTRACT

Semichemicals are important cucs influencing host selection by insect natural enemies of Heliothis spp. Chemicals produced by plants guide foraging entomophagous insects to suitable habitats where volatile and contact chemicals from host insects provide cues for the location of hosts. These behavior-modifying chemicals potentially can be utilized to screen exoticspecies prior to colonization and to improve rearing techniques. In addition, semiochemicals could be used as stimulants prior to release or be applied directly in the field to promote greater natural-enemy-induced mortality. Current and future studies on the behavioral responses of entomophagous insects to kairomones and synomones should improve 11 prospects for the development of practical techniques for managing their behavior in the field.
