Resistance and response of Pinus pinaster seedlings to Hylobius abietis

Short communication. A simple method for trapping Hylobius abietis (L.) alive in northern Spain

Hylobius abietis (L.) is the most economically important pest of coniferous seedlings in clear-cut areas in Europe. Adult weevils cause extensive damage by feeding on the bark of newly planted seedlings on clear felled coniferous stands. During the last 20 years, several studies have tried to find an effective method for trapping H. abietis in north Europe, but there is no information for the w...

Microbes Associated with Hylobius abietis: A Chemical and Behavioral Study

This thesis is based on three inter-related studies: the first part deals with the microbial consortium, the identification of microbes and their volatiles, the second part deals with the study of bio-chemical control methods of two conifer pests; the pine weevil Hylobius abietis (L.) and the root rot fungi Heterobasidion spp., and the third part describes the production of styrene by a fungus ...
