Pine barbel: black or bronze pest beetle
One of the unusual beetles can be called a black pine barbel. The pest poses a threat to coniferous forests and is able to reduce the number of trees. When Monochamus galloprovincialis appears, they immediately begin to fight them.

Description of the pine tree
Name: Black pine barbel, bronze pine barbel
Latin: Monochamu sgalloprovinciali spistorClass: Insects - Insecta
Squad: Coleoptera - Coleoptera
Family: Barbels - Cerambycidae
 | Habitats: | pine forests |
 | Dangerous for: | fir, spruce, larch, oak |
 | Means of destruction: | sanitary rules, biological methods |
The size of an adult varies between 1,1-2,8 cm. The color is black and brown with a bronze sheen. Flat short elytra are dotted with hair spots. The bristles can be gray, white, red.
The pronotum of females is transverse, while that of males is oblong. Scutellum whitish, yellow, rusty yellow. Lateral granules with single microspines are located on the belly.
Head with reddish hairs. The eyes are wide-eyed. The lower part of the body is covered with a reddish-bronze hairline. Middle tibiae with coarse brown setae.
Life cycle of a pine beetle
Barbel beetle: adults and larvae.
The embryo develops from 2 weeks to a month. In the middle of summer, larvae appear. After 1-1,5 months, the larvae settle in the wood. Most often, insects are in the subcrustal area and feed on sapwood and bast. The damaged trunk is filled with dust. Wintering of larvae occurs in the tree passage at a distance of 10-15 mm from the surface.
The pupation stage lasts from 15 to 25 days. Having formed, adults gnaw a hole and find a new place. Parasites choose weakened and sawn trunks for habitation.
Life cycle duration from 1 to 2 years. Activity is observed in June-July.
Beetles love sunlight. Usually they settle in well-warmed plantings. Males choose the upper part of the tree, and females choose the butt.
Habitat and diet
Pests feed on coniferous trees - pine and spruce. During the formation period, they are engaged in nibbling the bark of a pine tree. Larvae prefer wood, bast, sapwood. As a result, the tree weakens and dries out. The black pine barbel prefers the forest and steppe zone. Habitats:
- Europe;
- Siberia;
- Asia Minor;
- Caucasus;
- northern Mongolia;
- Turkey
Barbel control methods
Pine barbel beetle.
Ways to protect the forest and plantings carry out a number of methods of prevention and protection. To get rid of the barbel you need:
- timely carry out selective and clear cuts;
- clean the places of export and debarking of materials;
- systematically sample dead and dead wood;
- attract birds that feed on pests.
Conclusion
Damage to untreated wood by larvae leads the forest to technical disrepair. As a result, forestry is undermined. The black pine barbel belongs to the biological group of forest parasites. The fight against the parasite must be approached thoroughly in order to save the forest.
