Abstract

The effectiveness of topical applications of the juvenile hormone analog Fenoxycarb against selected developmental stages of the eastern spruce budworm, Choristoneura fumiferana (Clemens), was determined. Eggs at an early stage of embryogenesis (0–24 h old) were prevented from hatching and were more sensitive to the compound than older eggs (48–72 h old) and larval stages. Fifth-instar larvae displayed lethal morphogenetic effects following Fenoxycarb treatment, but third-instar larvae were refractory. Adult females constituted the most sensitive stage; treated insects laid eggs that failed to hatch. Untreated adult females that mated with Fenoxycarb-treated males also laid infertile eggs.

Résumé

L’efficacité d’applications locales d’un analogue de l’hormone juvénile, le Fenoxycarb, sur certains stades de développement de la Tordeuse des bourgeons de l’épinette, Choristoneura fumiferana (Clemens), a été déterminée. Les oeufs en phase initiale de l’embryogenèse (0–24 h) ne peuvent éclore après un traitement et sont plus sensibles à la substance que les oeufs plus vieux (48–72 h) ou les larves. Les larves de cinquième stade subissent des effets morphogénétiques létaux après l’application du Fenoxycarb, mais les larves de troisième stade sont réfractaires. Ce sont les adultes femelles qui constituent le stade le plus sensible; les femelles traitées pondent des oeufs incapables d’éclore. Les femelles adultes saines accouplées à des mâles traités au Fenoxycarb pondent également des oeufs stériles.
