Abstract

Males of Eucosma gloriola Heinrich (Lepidoptera: Tortricidae) were caught in pheromone traps for about 5 weeks from 17 May to 21 June in 1996 in three 6-year-old plantations of jack pine, Pinus banksiana Lamb. (Pinaceae), located near Ramsey, Ontario. Peak flight occurred during the first week of June. Pheromone trap catch was greatest about 1 h before and after sunset (2130 hours EDT). Moth flight began when all jack pine pollen cones and vegetative shoots were still under bud scales, and when flights were nearly completed the pollen cones had completed shedding pollen and needle pairs were visible on the new shoots. Pheromone traps placed near the top of trees caught the most males, suggesting that males search for females at tree-top level and that some visual or chemical cue(s) of the host tree may enhance the response of males to pheromone-baited traps.

Résumé

Des mâles de Eucosma gloriola Heinrich (Lepidoptera : Tortricidae) ont été capturés durant une période d’environ cinq semaines, soit du 17 mai au 21 juin 1996, dans des pièges à phéromone déployés dans trois plantations de pin gris, Pinus banksiana Lamb. (Pinaceae), de six ans situées près de Ramsey, Ontario. La période de vol maximale a été observée durant la première semaine de juin. Les captures les plus nombreuses ont été enregistrées une heure avant et après le coucher du soleil (21 h 30, HAE). Lorsque la période de vol s’est amorcée, tous les cônes mâles et toutes les nouvelles pousses de pin gris étaient encore recouvertes de leurs écailles. Lorsqu’elle a pris fin, les cônes mâles avaient libéré tout leur pollen et les paires d’aiguilles étaient visibles sur les nouvelles pousses. Les captures les plus nombreuses ont été observées dans les pièges à phéromone installés au niveau de la cime des arbres, ce qui porte à croire que la quête d’un partenaire sexuel par les mâles s’effectue à ce niveau ou qu’un signal chimique provenant des arbres hôtes vient accentuer la réponse des mâles aux pièges à phéromone.
