Abstract

The effects of sequential attack on gallery construction, oviposition, and reemergence by Dendroctonus frontalis Zimmermann were studied in the laboratory at 25 °C. Six mating pairs were allowed to attack bark slabs in groups of 2 pairs every 2 days. Total gallery and eggs per pair decreased with increasing day of attack. The time of attack had little effect on the distance and time from the gallery origin to the first egg. Distances between eggs were shortest for pairs attacking second and greatest for pairs attacking last. Inverse relationships of egg-bearing gallery length, oviposition period, and adult residence time were observed with the day of attack.

The basic behavioral and physiological mechanisms thought to influence reproduction of D. frontalis are discussed. A hypothesis for termination of oviposition is formulated from these mechanisms, which provides greater understanding of the effects of attack density on reproduction.

Résumé

Les effets de la séquence d'attaque sur la construction des galeries, la ponte et la ré-émergence chez Dendroctonus frontalis Zimmermann, ont été étudiés en laboratoire à 25 °C. Six couples de scolytes on été mis en présence de pièces d'écorce par groupes de 2 couples à tous les 2 jours. La longueur des galeries et le nombre d'oeufs par couple ont diminué avec le temps d'attaque. Le temps d'attaque a peu affecté la distance et le temps écoulé du début de la galerie jusqu'au premier oeuf pondu. La plus courte distance entre les oeufs a été observée avec les couples ayant attaqué en deuxième lieu, et la plus longue, avec les couples arrivés en dernier. Des relations inverses furent observées entre le jour d'attaque, et la longueur des galeries abritant des oeufs, la période de ponte, et la durée de séjour des adultes.

Les mécanismes comportementaux et physiologiques de base présumés comme ayant un effet sur le reproduction font l'objet de la discussion. Une hypothèse sur la termination de la ponte est formulée à partir de ces mécanismes. Elle permet de mieux comprendre les effets de la densité des scolytes attaquant sur la reproduction.
