The occurrence of nests of the pine processionary caterpillar (PPC), Thaumetopoea wilkinsoni Tarns (Lepidoptera: Thaumetopoeidae), was recorded in two 9-year-old plots planted with Pinus halepensis, P. brutia and P. eldarica in a randomized block design. Nest density was highest in P. eldarica and lowest in P. halepensis. The mean number of nests per tree and their frequency distribution indicate that the preference of the PPC is in the order P. eldarica >P brutia >P. halepensis;it is believed to be related to shape of the tree. Planting of P. eldarica in camping sites is not recommended, due to its high susceptibility to colonization by the PPC. © 1988 Springer Science + Business Media B.V.
