Exposure of fouth instars of Spilarctia obliqua Walker (Lepidoptera: Arctiidae) to excelsin over a 24 h period resulted in reduced feeding and growth rates. To distinguish between antifeedant and toxic effects, growth efficiency, calculated as the slope of the regression of the relative growth rate on relative consumption rate, was compared with results from antifeedant simulation and contact toxicity bioassays. From the results, it is concluded that excelsin exerts its toxic effects at the physiological level.

Des chenilles du quatrième stade larvaire de Spilarctia obliqua Walker (Lepidoptera: Arctiidae), exposées à l'excelsine pendant 24 h, ont des taux d'alimentation et de croissance réduits Afin de distinguer les effets d'inappétence des effets toxiques, le rendement de la croissance, calculé comme la pente de régression du taux de croissance relative sur le taux de consommation, a été comparé avec celui obtenu lors de bioessais sur l'inappétence et sur la toxicité de contact. Les résultats obtenus permettent de conclure que l'excelsine a des effets toxiques sur la physiologie des chenilles.
