Abstract

Oviposition preference and larval survival of Diprion pini on Scots pine clones in relation to foliage characteristics.

Abstract

When laying eggs, adult female Diprion pini discriminated between clones of Scots pine, Pinus sylvestris. Larval survival was affected by Scots pine clone but was not correlated with oviposition preference. Diprion pini laid most eggs on tougher needles of Scots pine. There was no evidence to suggest that D. pini is responding to the monoterpene composition of the foliage.
