 Lepidopteran pests of apple trees in the Lori region have been documented in specialised literature; however, research on these pests in Vanadzor has not been done, despite the fact that many dangerous insects, including lepidoptera, flooded into private gardens in the city of Vanadzor after extensive clearing of orchards nearby. In this area, private farms suffer substantial damage from caterpillars. Additionally, some pests’ caterpillars can induce allergic reactions, some of which can be very dangerous, when they come into contact with people’s skin, particularly that of youngsters.

 The investigation of this matter is the focus of this work.

As a result of our research, we identified 14 species of leafrollers of apple trees, which belong to the orders Lepidoptera, Coleoptera, Hemiptera and Homoptera. The greatest damage is caused by Apple ermine (Hypomoneuta malinellus Z.), Gypsy (spongy) moth (Lymantria dispar L.), Lackey moth (Malacosoma neustria L.), Brown-tail moth (Euproctis chrysorrhoea L.), Apple blossom weevil (Anthonomus pomorum L.), Tortrix moths especially Rose tortrix moth (Archips rosana L.), and Large fruit-tree tortrix (Archips podana L.). Entomophages have also been obtained, which belong to the families of Braconidae and the Ichneumonidae.
