Hamel, M., Bauce, E. and Lavallee, R. (1994) Feeding and Oviposition Interspecific Preferences of Adult White-Pine Weevil (Coleoptera, Curculionidae) in Quebec. Environmental Entomology, 23(4):923-929.

Résumé

Results from three-choice and no-choice bioassays conducted under controlled conditions, and results from a field experiment indicated that adult white pine weevil, Pissodes strobi (Peck), collected from both Norway spruce, Picea abies (L.) Karst, and eastern white pine, Pinus strobus L., plantations, significantly preferred Norway spruce to eastern white pine and white spruce, Picea glauca (Moench) Voss, for feeding and oviposition activities. Weevil populations from Norway spruce and eastern white pine plantations responded similarly in a three-choice bioassay and in the field experiment, but in a no-choice bioassay weevils from the eastern white pine laid significantly more eggs and produced more feeding cavities compared with those from the Norway spruce. Results from the three-choice bioassay indicated that host interspecific discrimination by the weevil is more pronounced on spring than on late summer bark. Insects from the no-choice bioassay showed significantly greater feeding and ovipositional responses on Norway spruce than on the other two host-species in the spring. However, in the fall, differences were not significant.
