Abstract

Callow adults of the pine shoot beetle, Tomicus piniperda L., were fed shoots of Scots pine, Pinus sylvestris L. (Pinaceae), to investigate the influences of shoot age and feeding duration on survival and weight of callow adults and to characterize the relationship between the volume of shoot tissue excavated and weight gain. Heavier callow adults had better survival than lighter ones, and survival was higher on current-year shoots than on 1-year-old shoots. A significant relationship was observed between the amount of tissue excavated by callow females on current-year shoots and their body weight gain, a trend not observed in callow males. These results suggest that beetle weight and survival may be reduced when availability of current-year shoots during maturation feeding is limited because of competition (i.e., during population outbreaks), thus negatively affecting the production of future generations.

Résumé

Des adultes ténéraux du scolyte des pins Tomicus piniperda L. ont été nourris de pin sylvestre Pinus sylvestris L. (Pinaceae) au cours d’une étude de l’influence de l’âge des pousses et de la durée de l’alimentation sur la survie et la masse des adultes ténéraux et pour définir la relation entre le volume de tissu de plante consommé et le gain de masse des insectes. Les adultes ténéraux plus lourds ont un taux de survie plus élevé que les plus légers et les insectes survivent mieux dans des pousses de l’année que dans celles de l’année précédente. Une relation significative a été observée entre la quantité de tissu prélevée dans les pousses de l’année par les femelles et leur gain de masse, une tendance qui ne semble pas prévaloir chez les mâles ténéraux. Ces résultats semblent indiquer que la masse et la survie de ces coléoptères peuvent être réduites si la disponibilité des pousses de l’année au cours de la maturation est limitée à cause de la compétition (i.e., au cours des explosions démographiques), une réduction qui peut affecter négativement la production des générations futures.
