 | | Frass from larvae of the corn earworm, Heliothis zea (Boddie) and scales from H. ea moths (that are known to contain the host-seeking stimulus, tricosane) stimulate and orient host-seeking activity in female Microplitis croceipes (Cresson), a larval parasite of H. ea, and Trichogramma spp., egg parasites of H. ea. |
 | | When larval frass, moth scales, and tricosane were used as sign stimui (releasers) for M. croceipes, T. pretiosum (Riley), and T. achaeae Nagaraji and Nagarkatti, respecively, at time of their release from laboratoy containers, parasite performance improved, resulting in significantly increased rates of parasitizatio over that of unstimulated parasites. |
 | | Stimulation of M. croceipes with larvql frass had an overriding effect on this parasite's innate tendency to disperse upon release, thereby increasing the numbers remainging and prolonging their retention in the target are. |
