Abstract

Attack and emergence of the engraver beetles Ips pini Say and I. latidens LeConte were measured in lodgepole pine (Pinus contorta var. latifolia Engelm.) naturally attacked by the mountain pine beetle, Dendroctonus ponderosae Hopk., in 1991. Sample trees were baited with the Ips pheromones ipsdienol and lanierone 1 week and 3 weeks after attack by the mountain pine beetle and again the following spring to observe the effects of the timing of bait placement. The densities of attack, egg gallery length, emergence, and hibernation of Ips species were measured. Ips latidens did not attack either the baited or unbaked trees at breast height until the spring of 1992 and the relatively low emergence was not significantly different by treatments. Among the 1991 treatments, the densities at breast height (1.3 m) of I. pini attack, egg gallery length, adult emergence in the fall of 1991, and numbers of hibernating adults in the duff were all highest for the 3-week treatment and lowest for the unbaked treatment. Significantly higher densities of beetles emerged and hibernated in the duff on the north sides of trees. Ips pini emergence in late summer 1992 from trees additionally baited in spring 1992 was significantly higher than for trees baited only in fall 1991. The density and temporal distribution of the emergence of both Ips species is discussed in relation to that of the mountain pine beetle.

Résumé

Le taux d’infestation et l’émergence des scolytes Ips pini Say et I. latidens LeConte ont été mesurés dans des pins vrillés (Pinus contorta var. latifolia Engelm.) déjà affectés naturellement par des Dendroctones du pin ponderosa, Dendroctonus ponderosae Hopkins, en 1991. Des arbres représentatifs ont été traités aux phéromones de I’ Ips, l’ipsdiénol et la laniérone, 1 semaine et 3 semaines après le début de l’infestation des dendroctones et de nouveau au printemps suivant, ce qui a permis d’étudier l’effet du moment où le traitement était administré. La densité des infestations, la longueur des galeries de ponte, l’émergence et l’hibernation des espèces d’Ips ont été mesurées. Ips latidens ne s’est pas attaqué aux arbres à hauteur de poitrine, que les arbres ait été traités ou non, avant le printemps de 1992 et l’émergence relativement faible n’apas été affectée significativement par les traitements. Après les traitements administrés en 1991, la densité à hauteur de poitrine (1,3 m) des I. pini, la longueur de leurs galeries de ponte, l’émergence des adultes à l’automne de 1991 et le nombres d’adultes en hibernation dans la litière du sol ont atteint leurs valeurs maximales après le traitement de 3 semaines et étaient minimaux en l’absence de phéromone. La densité des scolytes à l’émergence et celle des insectes en hibernation dans la litière du sol étaient significativement plus élevées du côté nord des arbres. L’émergence des I. pini à la fin de l’été 1992 était significativement plus élevée dans les arbres traités de nouveau aux phéromones au printemps de 1992 que dans les arbres traités seulement à l’automne de 1991. La densité et la succession temporelle des deux espèces d’Ips sont examinées en relation avec l’émergence du Dendroctone du pin ponderosa.
