oa Journal of the Entomological Society of Southern Africa - Phenology of Pinus radiata log colonization by the pine bark beetle Hylastes angustatus (Herbst) (Coleoptera: Scolytidae) in the south-western Cape Province
Phenology of Pinus radiata log colonization by Hylastes angustatus was recorded at Grabouw by means of weekly trap logs. Over the five year study period, 95% of all beetles were captured in September and October. This study facilitates correct timing of insecticide treatments to protect pine seedlings from attack.
