The name is slightly misleading because Large Pine Weevils feed on the living bark of most woody or herbaceous plants. This large weevil (10 -13mm) has orange or creamy-yellow bands on the elytra across a dark background. The timing of these feeding periods depends on both the physiological condition of the insects and the ambient temperature. It is important to note that the knapsack application of Cypermethrin is only effective for approx. Part of Springer Nature.

Hylobius abietis and species of Hylastes (Black Pine Beetles) breed principally in stumps and roots of felled trees of a wide range of conifer species. (Studien überHylobius abietis L. I.

The adults hibernate overwinter and then feed on the bark of mainly sapling fir, pine and spruce. The body length is from 8 - 14 mm. Immediate online access to all issues from 2019. Remove bark from the cleared area using a wood chisel. Most pine weevil feeding occurs between early March and November. Heavy damage can completely girdle stems and cause plant death. Hylobius abietis and species of Hylastes (Black Pine Beetles) breed principally in stumps and roots of felled trees of a wide range of conifer species. They may attack at any time of year when it is warm enough for insect activity. The period during which plants remain vulnerable to damage varies considerably, depending on plant size and species as well as insect populations. Pine weevil Hylobius abietis is the most dangerous pest of restock areas.

Coniferous forests and areas with coniferous trees. Hylobius abietis, the Pine weevil, Large pine weevil, and spruce weevil . It is therefore necessary to protect the plants directly through dipping and/or spraying with the insecticide Cypermethrin. Also include at least one major root and two root- stump junctions. 1.1 Life cycle of Hylobius abietis The length of the life cycle of H. abietis is dependent on different factors. Typically, after two growing seasons, Sitka spruce  will no longer be susceptible to damage. Felling a coniferous crop produces a large increase in breeding material for the pine weevil, whilst plant material suitable for adult feeding is reduced.

This damage can prevent the young tree growing. This damage can prevent the young tree growing. No successful means of controlling the population in the stumps is currently available. This species is regarded as the most important pest of conifer seedlings planted after clear felling throughout Europe especially in countries which use this way of forest management. The adults hibernate overwinter and then feed on the bark of mainly sapling fir, pine and spruce.
