A reinvestigation of the sex pheromone of the eastern spruce bud worm, Choristoneura fumiferana (Clem.), showed that it contains 11-tetradecenal in the ratio 96% trans-: 4% cis-. Field trapping showed the pure trans- compound to be only slightly attractive. Maximum attraction occurred in the range 2% to 5% cis-.

Résumé

De nouvelles recherches sur la phéromone sexuelle de la Tordeuse des bourgeons de l’Epinette Choristoneura fumiferana (Clem.), ont démontré qu’elle comporte du 11-tétradécenal dans une proportion de 96% trans- : 4% cis-. Le piégeage sur le terrain a indiqué que le composé pur trans- était assez peu attractif. L’attraction maximum se produisit dans la gamme variant de 2% à 5% cis-.
