38. Biodiversity of the entomophages of Proctotrupoidea (Hymenoptera) in fruit plantations in the region of Plovdiv. VII. Parasitic hymenoptera in the biological fight against pests in fruit gardens.

The research on the ecological complexes entomophages according to the most important groups of pests on the agricultural cultures and the forests is an important field in the fundamental researches on the parasitic and predatory insects.
