Abstract

Acephate implanted in trunks of black spruce, Picea mariana (Mill.) B.S.P., trees in the fall, 3 weeks before female bud flush, and at female bud flush reduced insect damage to cones and increased seed yields for 1 year. Second-year effects of the implants reduced insect damage to cones, but without increased seed yields. In the 2nd year, cones from trees treated at bud flush had the least insect damage and the highest residues of acephate and its toxic metabolite, methamidophos. Damage to treated cones by the spruce cone maggot, Strobilomyia neanthracina Michelson, the dominant insect in untreated cones, was insignificant in the 1st year and was reduced in the 2nd year.

Résumé

L’implantation d’acéphate dans les troncs d’épinette noires, Picea mariana (Mill.) B.S.P., durant l’automne, 3 semaine avant l’éclosion des bourgeons femelles et à l’éclosion des bourgeons femelles a réduit les dommages causés aux cônes par les insectes et augmenté la production de graines durant 1 an. La 2ème année, on a observé une réduction des dommages dus aux insectes, mais aucune augmentation de la production de graines. Durant la 2ème année, ce sont les cônes des arbres traité au moment de l’éclosion des bourgeons qui ont montré le moins de dommages attribuables aux insectes et le plus haut taux de résidus d’acéphate et de son metabolite toxique, le méthamidophos. Les dommages attribuables au principal ravageur des cônes, la mouche granivore de l’épinette, Strobilomyia neanthracina Michelson, ont été insignificants la 1ère année du traitement et mineurs la 2ème année.
