Abstract

Mixtures of the juvenile hormone analogue (JHA) methoprene and each of three benzoylphenylureas (BPUs) were fed to sixth-instar western spruce budworm, Choristoneura occidentalis Freeman. The BPUs tested were diflubenzuron, BAY SIR 8514 (N-[(trifluoromethoxy)phenyl]carbamoyl-2-chlorobenzamide), and EL-127063 (N-[[[5-(4-bromphenyl)-6-metnyl-2-pyrazinyl]amino]carbonyl]-2-chlorobenzamide). Mixtures consisted of JHA:BPU combined in 1:9 proportions. Ingestion of methoprene combined with BAY SIR 8514 or diflubenzuron resulted in significantly lower mortality than expected under a simple model of uncorrelated, independent action. Ingestion of the mixture of methoprene and EL-127063, however, resulted in significantly enhanced toxicity over the upper response range (> 50% mortality).

Des mélanges de l'analogue de l'hormone juvénile (AHJ) méthoprene avec l'un ou l'autre de trois composés de type benzoylphénylurée (BPU) ont été donnés en nourriture à des larves de sixième stade de la tordeuse occidentale de l'épinette, Choristoneura occidentalis Freeman. Les trois composés de type BPU testés étaient le diflubenzuron, BAY SIR 8514 (N-[(trifluoromethoxy)phenyl]carbomoyl)-2-chlorobenzamide), et EL-127063 (N-[[[5-(4-bromphenyl)-6-methyl-2-pyrazinyl]amino]carbonyl]-2-chlorobenzamide). Les mélanges étaient faits de AHJ : BPU aux proportions de 1 : 9. L'ingestion de méthoprene en combinaison avec le BAY SIR ou le diflubenzuron a causé significativement moins de mortalité que prévu selon un modèle d'action simple indépendante et non corrélée. Par ailleurs, l'ingestion du mélange méthoprene avec EL-127063 a causé une toxicité significativement augmentée par rapport à la partie supérieure de la courbe de réponse (> 50% de mortalité).
