Abstract :

Toxicity assays with tebufenozide, the first commercial non-steroidal ecdysteroid agonist, against a laboratory strain of the beet armyworm, Spodoptera exigua (Hbner), demonstrated the promise of this new compound for the control of this important pest. Experiments to select insects artificially from the laboratory strain by continuous exposure of larval instars to corresponding LC25 doses of tebufenozide for over 12 generations (G0->G12: 14-15 months), revealed no loss in susceptibility to the insecticide for up to five generations. Moreover, retention and fate of 14C-labelled tebufenozide were investigated using G6 larvae from the selection experiments and the results compared with those for the susceptible (G0) larvae. In addition, piperonyl butoxide, an inhibitor of monooxygenases, when ingested by larvae along with tebufenozide, increased the susceptibility of intoxicated larvae to this ecdysteroid agonist, indicating its oxidative metabolism in Spodoptera larvae.
