Repeating outbreaks of the Scots pine pests, effecting in stands damages, are the most important problems of forest protection. In extreme cases they pose a real threat to the stability of stands. Naturally occurring entomopathogenic nematodes are important regulatory factors in insect populations. Many species are employed as biological agents to control the insect pests. The objectives of this research...
