It is common in Scotland, but less common in England. 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. Beyer-Petersen, B. Juutinen, P. Kangas, E. Bakke, A. Butovitsch & M. Eidmann Anzeiger für Schädlingskunde volume 37, pages 14 – 15 (1964)Cite this article The large pine weevil (Hylobius abietis) can cause very substantial tree plant mortality in reforestation sites.

Young trees used for restocking are liable to be heavily attacked by adult pine weevils feeding on the stem from the root collar upwards. This large weevil (10 -13mm) has orange or creamy-yellow bands on the elytra across a dark background. They may attack at any time of year when it is warm enough for insect activity. 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. Many adult pine weevils can emerge from a single stump and associated root system, resulting in populations as high as 100,000 adults per hectare.

If the average count on a site felled more than 12 months is. Acta Entomol Fenn 17:1–106 Google Scholar The timing of these feeding periods depends on both the physiological condition of the insects and the ambient temperature. The adults hibernate overwinter and then feed on the bark of mainly sapling fir, pine and spruce. Hylobius abietis, the Pine weevil, Large pine weevil, and spruce weevil . Above is an adult Pine weevil, also sometimes called the Large pine weevil or Spruce weevil, Hylobius abietis, native to northern Europe and Asia. Coniferous forests and areas with coniferous trees.

Pine weevil Hylobius abietis is the most dangerous pest of restock areas. Development and life cycle in the Nordic countries. Clear the soil away from a quarter of a stump, at least 40 cm out and 30 cm down from soil level. 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. Entwicklung und Generationsdauer in den nordischen Ländern.) Count the number of weevil larvae and pupae. The adults hibernate overwinter and then feed on the bark of mainly sapling fir, pine and spruce. Development and life cycle in the Nordic countries. Sample at least five stumps. This method should be viewed as an indicator only. The weevils cause damage by eating the bark of seedlings thus preventing its further growth, or even killing them. Heavy damage can completely girdle stems and cause plant death.

Moran ABSTRACT Hylobius abietis (Coleoptera: Curculionidae), the large pine weevil is the most damaging pest of reforestation sites in Ireland. Another factor Figure 1: An adult Hylobius abietis. Anzeiger für Schädlingskunde 37, 14–15 (1964). The period during which plants remain vulnerable to damage varies considerably, depending on plant size and species as well as insect populations. Although it is widespread throughout Britain, it is rather local, with populations being dependant on the food plant being available in numbers. Adult large pine weevils may live for up to four years. Life History. Most will feed on adjacent mature trees or on weed species on site, but heavy feeding damage on trees planted on reforestation sites is also very likely. 1.1 Life cycle of Hylobius abietis The length of the life cycle of H. abietis is dependent on different factors. Most pine weevil feeding occurs between early March and November. Thank you. It is important to note that the knapsack application of Cypermethrin is only effective for approx. The name is slightly misleading because Large Pine Weevils feed on the living bark of most woody or herbaceous plants.
