Abstract

Three types of traps were tested in 1969 and 1970 for collecting pupae of the eastern hemlock looper, Lambdina fiscellaria fiscellaria (Guen.). Highest numbers of pupae were obtained with burlap traps made from 2-ft-wide bands wrapped around trunks of infested trees. The proportion of the pupae in the burlap traps was estimated. Some of the potential uses for pupae collected by the method are mentioned.

Résumé

Trois sortes de piège étaient mises à l’épreuve en 1969 et 1970 dans la collection des chrysalides l’Arpenteuse de la pruche, Lambdina fiscellaria fiscellaria (Guen.), dont le plus grand nombre était obtenu avec l’aide des pièges de serpillière en forme de bandes de deux pieds de large roulées autour des troncs des arbes infestés. La proportion des chrysalides dans les pièges était calculée. L’utilisation possible des chrysalides ainsi collectionnées y est mentionnée.
