Effect of an ecdysone agonist, RH 5849, on wandering behaviour in Spodoptera littoralis
Wandering behaviour of the fall armyworm, Spodoptera littoralis has been examined using a video-digitizing computer system. Ecdysteroid titers prior to and during wandering have been determined using an enzyme immunoassay. RH 5849, an agonist of 20-hydroxyecdysone (20E) applied at various times before wandering to last instar larvae of S. littoralis caused a delay in the onset of wandering, varying from 0.5 to 4.5 hr. This delay was dose dependent. We suggest that wandering in S. littoralis may be induced by a decrease in ecdysteroid titers.
