“…Also, it is interesting to note a strong correlation between pupal chambers and emergence holes with the number of insects from both groups of natural enemies. Harman and Kulman (1968) also observed that the abundance of associated species increases with white pine weevil abundance. However, the predators were not related to overstory basal area and this may suggest that their role can be considered as proportionally more important under overstory cover because there are fewer weevils.…”

“…However, the predators were not related to overstory basal area and this may suggest that their role can be considered as proportionally more important under overstory cover because there are fewer weevils. Harman and Kulman (1968) also reported that L. corticis emerged with the highest percentage from leaders in natural stands with an overstory. McLean (1989) also observed this trend in British Columbia on Sitka spruce planted under a canopy of red alder.…”

“…The number of emerging adults per leader we observed under the canopy (Table 1) is similar to the four to five larvae able to complete their development, as reported by Katovich (1992). Harman and Kulman (1968) reported an average of 12.3 weevils per white pine leader and LavallCe et al (1993) 29.2 weevils per leader from an opengrown plantation. Consequently, under a canopy, even if the weevil is still present in the environment, the population level will remain low and the impact will be insignificant on taller pines.…”

“…This treatment allows some larvae of Eurytoma pissodis Girault, a hymenopteran parasitoid, to complete their life cycle and emerge as adults, leaving an easily identifiable circular hole of about 1.3 mm diameter (Taylor 1929, McLean 1989. However, Harman and Kulman (1968) For personal use only. presents some difficulties, in the text reference will be made to this general group of insects.…”

“…Moreover, their influence added to the cover influence can greatly affect weevil populations. In a previous study, Harman and Kulman (1968) concluded that understory white pines appeared less favourable for weevils since (1) they yielded the lowest number of weevils emerging per leader, (2) they had the highest percentage of leaders yielding associated predator species and (3) they had the lowest percentage of leaders yielding weevils.…”

The white pine weevil's (Pissodes strobi Peck) feeding, oviposition and emergence were studied in a 12-year-old (1998) white pine (Pinus strobus L.) progeny test established under a canopy of mature pioneer species in the Outaouais region (Notre-Dame-du-Laus, QuCbec, Canada). The basal area of the overstory centred on 63 white pines was used as an indicator of forest cover. With overstory basal area ranging from 0 to 16 m2/ha, some white pine weevil performance parameters such as feeding and oviposition were significantly correlated with forest cover. However, others like the number of pupal chambers, emergence holes, partial survival index (emergence holeslchip-cocoon punctures) and total survival index (oviposition punctures/emergence holes) were not. Results showed that with an increase of forest cover, tree height was not affected but tree bole diameter was reduced. No relation was observed between leader diameter and the number of oviposition punctures. Even under a canopy, natural enemies (Lonchaea corticis Taylor and hymenoptera parasitoids) were also noted to reduce larval and pupal white pine weevil populations.Key words: white pine weevil, white pine, undercover plantation, natural biological control, oviposition, feeding, emerging population, overstory basal area L'alimentation, la ponte et 1'Cmergence du charangon du pin blanc (Pissodes strobi Peck) ont Cte CtudiCes dans un test de descendance familiale de pins blancs (Pinus strobus L.) alors dgCs de 12 ans.

Insects associated with the Sitka spruce weevil, Pissodes strobi (Peck), on Sitka spruce, Picea sitchensis (Bong.) Carr. were sampled at 9 locations in British Columbia. Fourteen species of hymenoptera, 3 diptera, and 1 psocopteran were found associated with the weevil. Samples were dominated by the lonchaeid predator, Lonchaea corticis Taylor, and to a lesser extent by the braconid parasitoid, Allodorus crassigaster (Prov.).
