Trudel, R., Lavallee, R. and Bauce, E. (2001) Oviposition biology of Pissodes strobi (Coleoptera : Curculionidae) on white pine (Pinaceae) under laboratory conditions. Canadian Entomologist, 133(3):333-341.

Résumé

Studies were conducted to document the oviposition biology of female white pine weevil, Pissodes strobi Peck. Data were recorded on female fecundity and daily feeding and oviposition activities. II? addition, we compared fecundity of 1- and 2-year-old females. Female white pine weevils laid a mean rt SE total number of 132.3 +/- 7.5 eggs (range 40-344 eggs) during an average oviposition period of 5.8 +/-0.4 weeks. It is during the first 5 weeks that white pine weevils lay the most eggs, with an egg-laying peak in the second week of the oviposition period. For a few females, egg production did not cease until the 22nd week. There was no difference between the number of eggs laid in the photophase and in the scotophase, but higher numbers of feeding punctures were observed during the night than during the day. The oviposition and feeding results for 2-year-old female white pine weevils were similar to those for I-year-old females. This information contributes to the management of white pine weevils by providing a better understanding of some of the mechanisms of its population dynamics.
