Abstract

The hemlock looper, Lambdina fiscellaria, is one of the most economically damaging defoliators of North American coniferous forests. Basic information on its reproductive biology is an essential prerequisite for understanding its population dynamics. Realized fecundity for the two major hemlock looper ecotypes varies along a latitudinal gradient in eastern Canada, but their daily oviposition patterns are similar. Mated females lay eggs after a short pre-oviposition period, with daily oviposition peaking in the first 3 days. Mated females lay significantly more eggs than unmated ones, the latter laying their eggs more evenly throughout their life. Eggs deposited early in the oviposition period are larger than those deposited near the end. This may influence over-winter survival of hemlock loopers and should be considered in studies to better understand the population dynamics and improve management of this defoliator.

Résumé

L'arpenteuse de la pruche, Lambdina fiscellaria, est l'un des plus importants défoliateurs des forêts de conifères de l'Amérique du Nord. Obtenir l'information de base sur la biologie reproductrice d'un ravageur est une condition préalable essentielle pour comprendre la dynamique de ses populations. Des variations de fécondité sont connues pour les deux écotypes majeurs de l'arpenteuse de la pruche le long d'un gradient latitudinal, dans l'est du Canada, mais leur taux de ponte journalière est similaire. Les femelles accouplées pondent rapidement des œufs après une courte période de préoviposition, le maximum survenant dans les 3 premiers jours suivant le début de l'oviposition. Les femelles accouplées pondent significativement plus d'oeufs que les femelles non accouplées et ces dernières montrent un patron de ponte journalière plus uniforme pendant toute leur vie. Par ailleurs, les œufs pondus au début de la période de ponte sont plus volumineux que ceux déposés vers la fin de cette période. Cette différence pourrait influencer la survie hivernale de l'arpenteuse de la pruche et devrait faire l'objet d'études afin de mieux comprendre la dynamique des populations et améliorer la gestion de ce défoliateur.
