The blue pine jewel beetle ( Phaenops cyanea ) is a beetle from the family of jewel beetles and the subfamily Buprestinae .
features
The color of the jeweled blue beetle ranges from green to blue to black. It is about 7 to 12 millimeters long. The larva is spoon-shaped and about two centimeters long.
Way of life
The preferred habitat are mostly pine stands. In rare cases, spruce stands can also be attacked. Above all, weakened trees are colonized. The larva develops into a full insect within two years. The tunnels created by larval feeding weaken the tree so that an infested tree is usually also attacked by other insects and ultimately dies. Through the cultivation of pine monocultures, it has developed into a pest that is important for forestry.
activities
There are no preventive measures to control the pine jewel beetle. Infested trees can be felled and barked to avoid excessive reproduction. It is important that the bark is burned or buried, since the larvae do not die by debarking alone.
