Abstract

In this research, almond pets in forests and identified measures were studied. According to the results of the research, the main pests of the genus Lepidoptera in forestry were almonds (Erschoviella musculana Ersch.), Oriental fruit on the branches, unequal silkworm on the leaves (Lymantria dispar L.) and fragrant wood on the body). It was noted that walnut pest was the dominant among the observed pests. The results of the experiment on almond pests represented that 12 species of entomophagous almonds were recorded, including Braconidae, Trichogrammatidae, Ichneumonidae, Chalcidoidae, Pteromalidae, Encyrtidae, Tachinidae, Coccinellidae, Chrysopidae. Furthermore, representatives of the families of Miridae, including Microgaster nemorum Hrtg., Microdus rufipes Nees., Macrocentrus delicatus Cress., Ascogaster quadridentatus Trichogramma embryophagum Htg., Trichogramma evanescens Gir., Diadegma armillatus Grav., Pimpla inquisitor Scop., Liotrifon punctulatus were identified. Avaunt with 15% (0.5 l/ha) and Mospilan with 20% (0.4 kg/ha) were used against the main almond pests, and biological efficiency was achieved by 88.8% and 94.8%, correspondingly.
