Abstract:
A spruce forest of Artvin has given great
losses by the effects of pest insect species since the 1980s. In 1980-2010,
about 1 million m3 spruces have been dried up as a result of bark
beetle species. In 1990s, Dendroctanus micans, Ips typographus, Ips
sexdentatus have caused to dry 50 to 100 thousand m3 per year.
At first, primary damages which caused by D.micans had increased effects
of other bark beetles. Ips typographus (spruce bark betle) was first
recorded in Artvin Province (Turkey) in 1984. Ips sexdentatus is native
species in Artvin. Mechanical, biotechnology and biological struggles have been
carried out against these harmful insects for 33 years and struggle of insects
has been conducted successfully. Against D.micans in Artvin, chemical
struggle was made between 1970 and 1985, and biological and mechanical struggle
was made between 1985 and 2003. After 2003’s, R.grandis which produced
in laboratories has been sent to spruce forests of Erzurum and Trabzon. In
laboratory conditions, 3,567,675 units Rhizophagus grandis have been
produced against D.micans until the end of 1985-2011. As a result of
biotechnical struggles have made against Ips typographus until the end
of 1997-2011, 133.122 pheromone traps have been hanged in 94.410 hectare areas
and this traps have caught 382.753.778 adult insects. In recent years, Thanasamus
formicarius has been produced against bark beetles in the laboratories. Up
to this day, as a result of the struggles which made against these three bark
beetles, ecological balance has been provided.
