Harmful insects cause serious damage to the forest

May 16, 2010 by timbercommunity

European Spruce Bark Beetle, pine weevil and european pine sawfly are harmful insects which cause serious damage to the forest.  One tree produces 10 000 spruce bark beetles. One hectare produces 10 million spruce bark beetles. In order to avoid the spruce bark beetle it is important to directly remove wind-felled trees. It is also necessary to set up non-toxic  pheromone traps wich is more cost effective in the long run compared with using insecticide-treated traps. Since year two you will only have the cost of buying pheromone.

It is technical possible with image recognition and laser that could theoretically be used to track insects and  zap them down. Watch this cool video to view such gizmo against malaria mosquitos.
 

In a new report from Swedish Forest Agency estimates that up to 100 000 m3sk can be damaged by the European spruce bark beetle during 2010. Although pine weevil and European Pine Sawfly are likely to also cause extensive damage. On May 12, the Forest Service leaved the first report this year's to the Swedish Government from the project called Insect control. By the inventories carried out today, they have an inventory of the situation n terms of damage from the spruce bark beetle, and red pine weevil and European Pine Sawfly. In the report the organisation say it is important that forest owners will continue to keep watch on their forests and take care of infested wood.  
 
Here is a summary of the findings from the report from the Forest Board: 
Forest Board believes that up to 100 000 m3sk can be damaged by the spruce bark beetle in 2010, significantly lower volume than in 2009, but new storms and / or a dry summer may increase this number.  
A survey shows that the areas in the northeastern part of Kronoberg County is heavily infested with European Pine Sawfly. Forest Service estimates that the damage will continue during 2010 in areas with major damage 2009th  
Damage by pine weevil are still large in some parts of the storm area. The monitoring of pine weevil damage is continuing in 2010. There is a great need for awareness-raising activities for forest owners about how important it is to carry out preventive measures.  

Inventories show that heavy wet snow in February caused extensive damage to local pine and spruce on the south Swedish highlands and parts of west of Sweden. Most heavily affected is 20-45 year old forest thinning, which means the risk of infestation of spruce bark beetle, beetle, and more marrow six teethed bark beetle.

Forest Service plans to implement the planned monitoring activities. They also intends to provide active employees, foresters and other target audiences with information about combat operations against the spruce bark beetle, Pine Sawfly and pine weevil.
