The body length is from 8 - 14 mm. This method should be viewed as an indicator only. Tax calculation will be finalised during checkout. The period during which plants remain vulnerable to damage varies considerably, depending on plant size and species as well as insect populations. Large Pine Weevil. Clear the soil away from a quarter of a stump, at least 40 cm out and 30 cm down from soil level. volume 37, pages14–15(1964)Cite this article. 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., Over 10 million scientific documents at your fingertips. 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. Douglas fir on the other hand remains susceptible for several growing seasons. Recording the wildlife of Leicestershire and Rutland. It is important to note that the knapsack application of Cypermethrin is only effective for approx. Infrequent in Leicestershire and Rutland. Michael G. Moran ABSTRACT Hylobius abietis (Coleoptera: Curculionidae), the large pine weevil is the most damaging pest of reforestation sites in Ireland. 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. Subscription will auto renew annually. Above is an adult Pine weevil, also sometimes called the Large pine weevil or Spruce weevil, Hylobius abietis, native to northern Europe and Asia. 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. 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. Hylobius abietis (Linnaeus, 1758) (Pine Weevil) Interactions where Hylobius abietis is the victim or passive partner (and generally loses out from the process) . Also include at least one major root and two root- stump junctions. © 2020 Springer Nature Switzerland AG. This damage can prevent the young tree growing. Adults can live up to four years. PubMed Google Scholar, Beyer-Petersen, Juutinen, B., Kangas, P. et al. The large pine weevil (Hylobius abietis) can cause very substantial tree plant mortality in reforestation sites.

''Hylobius abietis'' or the large pine weevilis a beetle belonging from Curculionidae. Most pine weevil feeding occurs between early March and November. The following relationships have been collated from the published literature (see 'References'). Typically, after two growing seasons, Sitka spruce  will no longer be susceptible to damage. The weevils cause damage by eating the bark of seedlings thus preventing its further growth, or even killing them. 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. The relative magnitude of these peaks will vary from forest to forest and from year to year. Remove bark from the cleared area using a wood chisel. Development and life cycle in the Nordic countries. 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. 6 weeks, so predicting the optimum time of application is critical.
