Hylobius abietis or the large pine weevil is a beetle belonging to family Curculionidae.This species is widely regarded as the most important pest of most commercially important coniferous trees in European plantations. Seedlings planted or arising from natural regeneration (germinated seed-fall) after clear felling operations are especially at risk.
The sand sticks to the glue on the plant. Even though the grains of sand are very small, they are large enough to prevent the pine weevil’s jaws from getting past them. At the same time, the grains of sand are not so large that gaps are formed, through which the pine weevil could get to the stem.
In the prairie provinces of Canada, white pine weevil is considered a serious pest of jack pine, red pine, and Scots pine, and an occasional pest of mugho pine. To our knowl-edge, white pine weevil does not attack these pines in Idaho. INSECT IDENTIFICATION The adult insect is a 1/4-inch long weevil that is mottled brown (Fig. 2).

Information on host(s) Although it occurs naturally in our forests, in eastern Canada, it is considered to be the most serious pest of white pine, jack pine and Norway spruce plantations.
Pine weevil Hylobius abietis is the most dangerous pest of restock areas. Where chemical insecticides are used, there are costs associated. For example in Ireland, the cost of pre-treatment of plants and of treating planted plants in Coillte forests was an average of …
As weevil infestations take place almost entirely inside packages of stored foods, they can be hard to detect and even harder to eradicate. To truly end your weevil infestation, you will need to the help of a professional pest control service.
Gather the vacuumed weevil debris and the infested food items and pack them in new, sealed, plastic bags. Dump these bags, and then follow this with a thorough cleaning of the vacuumed site. An infested area usually has hard-to-see chemical traces that can attract weevils in the future, so prepare a cleaning mixture with some water and your basic kitchen/washroom disinfectant solution.
I’ve used Pine Resin Glue to make fish-hooks, frog gigs and all kinds of other useful tools. I’ve also used Pine Resin Glue at home for every day projects. In this post, we will use Pine Resin Glue to secure Ferrocerium Rod Fire Steel Blanks inside of pre-drilled deer antler handles. Pine resin can be found on almost EVERY pine tree.
• Stem coats (sand and glue, wax, etc.) • Barrier guards (tubes around the stem) Lethal and non-lethal effects • Insecticides (acetamiprid, cypermethrin, etc.) • Feeding deterrence • Artificially induced defences Reduce pine weevil population • Nematodes (infest larvae) • Fungi • Parasitoids, ants, predators etc.
The glue/sand combination is estimated to give the tiny trees two years of protection from weevil damage – something that’s critical as they’re being established as new plantings. Within a couple of years, the company anticipates that up to 50 million plants will be treated with Conniflex replacing the need to spray the trees with pesticides.
The pine weevil also feeds on branches of mature trees and can be a vector of damaging fungal pathogens (Leather et al., 1999). Despite pine weevil being recognised as a serious pest since the beginning of the last century (Leather et al., 1999) it remains a highly damaging agent to commercial forestry in the UK (Willoughby et al., 2017).
Vine weevil eggs. All vine weevil adults are female, and each one can lay hundreds to thousands of eggs from April to September; the main egg-laying periods are April and August/September. If you spot golden-brown or clear egg-like objects in the soil or compost then they're NOT vine weevil eggs.
Common Weevil Damage. Root weevils, including black vine weevils and strawberry root weevils, cause notching damage, while white pine weevils cause terminal growth to wilt and die. Some weevils invade stored grain in farms and even in home pantries, where people will find weevils in food.
pine blister rust, the white pine tip weevil, and the pine bark beetle. Blister rust problems can be severe in certain parts of Wisconsin. To minimize these problems, do not plant white pine where the incidence of blister rust is high, unless you can eradicate gooseberry and currant bushes (the rust's alternate host plants) from the area.

Vine weevil adults can often be found hiding under the base or lip of pots, so check regularly and squash any you find. Another technique used by some gardeners is to go out at night with a torch and shine it on the leaves of vulnerable plants, where you might spot the beetles feeding.
Vine weevil is a beetle that feeds on a wide range of plants, both indoors and outdoors, but can be especially damaging to plants grown in containers. It is a very widespread and common insect. The adult weevils eat leaves during spring and summer, but it is the grubs that can cause the most damage over autumn and winter when they feed on plant roots.
Weevils are beetles belonging to the superfamily Curculionoidea, known for their elongated snouts.They are usually small, less than 6 mm (1 ⁄ 4 in) in length, and herbivorous.About 97,000 species of weevils are known. They belong to several families, with most of them in the family Curculionidae (the true weevils).Some other beetles, although not closely related, bear the name "weevil", such ...

glue, wax and pigment, can affect the plant’s capacity to photosynthesise. Photosynthesis measurements on pine seedlings confirmed the hypothesis, and indicate that the coating can limit photosynthesis in two ways, by acting as a barrier to light and/or gas exchange.
