oa Journal of the Entomological Society of Southern Africa - Phenology of Pinus radiata log colonization and reproduction by the European bark beetle Orthotomicus erosus (Wollaston) (Coleoptera: Scolytidae) in the south-western Cape Province



The temporal distribution of Orthotomicus erosus (Woll.) beetles within a Pinus radiata plantation near Grabouw was recorded from weekly trap logs over a period of five years. O. erosus is summer active. The number of eggs and larvae produced by these beetles was monitored for two years and showed that colonization is followed immediately by brood production.
