Abstract

Pre-attack feeding for 48 h on a diet containing 200 ppm Dimilin® (diflubenzuron), by adult Dendroctonus rufipennis (Kirby) (Coleoptera: Scolytidae), caused a complete inhibition of larval eclosion from eggs deposited by such beetles in the untreated host logs for the duration of the reproductive cycle. Inhibition of larval eclosion was mediated through the females only. Pre-attack application of 1% Dimilin to host logs reduced the number of larvae per gallery by 55% and reduced the number of galleries with successful larval eclosion by 42%.

Résumé

Le nourrissement pendant 48 heures avant l’attaque de Dendroctonus rufipennis (Kirby) (Coleoptera : Scolytidae) avec une diète contenant 200 ppm de Dimiline, a causé l’inhibition complète de l’éclosion des larves des oeufs pondus par ces insectes dans les billes-hôtes durant tout le cycle de reproduction. Cette inhibition s’est transmise seulement par les femelles. L’application de Dimiline à 1% aux billes-hôtes avant l’attaque y a réduit de 55% le nombre de larves par galerie et de 42% le nombre normal de galeries avec l’éclosion des larves.
