This large weevil (10 -13mm) has orange or creamy-yellow bands on the elytra across a dark background. Young trees used for restocking are liable to be heavily attacked by adult pine weevils feeding on the stem from the root collar upwards. Acta Entomol Fenn 17:1–106 Google Scholar They may attack at any time of year when it is warm enough for insect activity. Studies onHylobius abietis L. I. Subscription will auto renew annually. Where chemical insecticides are used, there are costs associated. Hylobius abietis, the Pine weevil, Large pine weevil, and spruce weevil . Although it is widespread throughout Britain, it is rather local, with populations being dependant on the food plant being available in numbers. Bejer-Petersen B, Juutinen P, Kangas E, Bakke A, Butovitsch V, Eidmann H, Heqvist KJ, Lekander B (1962) Studies on Hylobius abietis L. I. The large pine weevil (Hylobius abietis) can cause very substantial tree plant mortality in reforestation sites.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. It is therefore necessary to protect the plants directly through dipping and/or spraying with the insecticide Cypermethrin. 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. Tax calculation will be finalised during checkout. Douglas fir on the other hand remains susceptible for several growing seasons. FIELD ENHANCEMENT OF THE PARASITOID Bracon hylobii (Hymenoptera: Braconidae) TO CONTROL Hylobius abietis (Coleoptera: Curculionidae); THE LARGE PINE WEEVIL. ''Hylobius abietis'' or the large pine weevilis a beetle belonging from Curculionidae. This damage can prevent the young tree growing. PubMed Google Scholar, Beyer-Petersen, Juutinen, B., Kangas, P. et al. The following relationships have been collated from the published literature (see 'References'). Sample at least five stumps. The name is slightly misleading because Large Pine Weevils feed on the living bark of most woody or herbaceous plants. This is a preview of subscription content, log in to check access. 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. 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.). Michael G. Moran ABSTRACT Hylobius abietis (Coleoptera: Curculionidae), the large pine weevil is the most damaging pest of reforestation sites in Ireland. The timing of these feeding periods depends on both the physiological condition of the insects and the ambient temperature. Pine weevil Hylobius abietis is the most dangerous pest of restock areas. 6 weeks, so predicting the optimum time of application is critical. 1.1 Life cycle of Hylobius abietis The length of the life cycle of H. abietis is dependent on different factors. Enter a town or village to see local records, Yellow squares = NBN records (all known data) Adult large pine weevils may live for up to four years. Above is an adult Pine weevil, also sometimes called the Large pine weevil or Spruce weevil, Hylobius abietis, native to northern Europe and Asia. Another factor Figure 1: An adult Hylobius abietis. There were a total of 12 VC55 records for this species up to March 2015. Felling a coniferous crop produces a large increase in breeding material for the pine weevil, whilst plant material suitable for adult feeding is reduced. Large Pine Weevil. Part of Springer Nature. Development and life cycle in the Nordic countries. Anzeiger für Schädlingskunde 37, 14–15 (1964). The body length is from 8 - 14 mm. Thank you. The adults hibernate overwinter and then feed on the bark of mainly sapling fir, pine and spruce. Remove bark from the cleared area using a wood chisel. Recording the wildlife of Leicestershire and Rutland. In warmer climates, the developmental time can be 2 years, while in cooler climates, the time to develop from egg till adult can take 3 years. Beyer-Petersen, B. Juutinen, P. Kangas, E. Bakke, A. Butovitsch & M. Eidmann Anzeiger für Schädlingskunde volume 37, pages 14 – 15 (1964)Cite this article It is common in Scotland, but less common in England. This method should be viewed as an indicator only. However, there is a tendency for two peaks of damage to occur, one in spring before egg laying and the other in late summer before the adults hibernate underground. The weevils cause damage by eating the bark of seedlings thus preventing its further growth, or even killing them. For example in Ireland, the cost of pre-treatment of plants and of treating planted plants in Coillte forests was an average of €1.6 million over the five years from 2009 to 2013 inclusive.

No successful means of controlling the population in the stumps is currently available. 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. Studies onHylobius abietis L. I. Count the number of weevil larvae and pupae. Clear the soil away from a quarter of a stump, at least 40 cm out and 30 cm down from soil level. 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. Coniferous forests and areas with coniferous trees. It is important to note that the knapsack application of Cypermethrin is only effective for approx.

Development and life cycle in the Nordic countries. Most pine weevil feeding occurs between early March and November. The relative magnitude of these peaks will vary from forest to forest and from year to year. Weevil larvae are not segmented or ridged and tend to form a C shape.
