| Abstract | The article highlights the species composition and effectiveness of natural enemies of the woolly apple aphid (Eriosoma lanigerum Hausmann) in various countries around the world. It has been established that the population of Eriosoma lanigerum Hausmann is regulated globally by 85 species of predatory insects, five species of Hymenopteran endoparasitoids, two species of Acari (ectoparasites), seven species of fungal pathogens, one species of entomopathogenic nematode, and a plant whose seeds exhibit a bioinsecticidal effect. All predatory insects feeding on Eriosoma lanigerum belong to five orders—Coleoptera, Diptera, Neuroptera, Dermaptera, and Hemiptera and six families: Coccinellidae, Syrphidae, Chrysopidae, Hemerobiidae, Forficulidae, and Lygaeidae. The most numerous group of predators is the family Coccinellidae, which includes 36 species 43% of all predatory insects associated with the woolly apple aphid. The second largest group is Diptera, represented by 24 species of the Syrphidae family. It has been determined that, in addition to the specialized endoparasitoid Aphelinus mali, which has been introduced into all apple-growing regions for the control of Eriosoma lanigerum, the aphid population may also be effectively regulated by ladybirds such as Coccinella transversoguttata Fald. And Hippodamia convergens Guer.; hoverflies such as Heringia calcarata Loew, Eupeodes americanus Wiedemann, and Syrphus rectus Osten-Sacken; green lacewings; the common earwig; two ectoparasites of the family Erythraeidae (subclass Acari): Balaustium putmani Smiley and Allothrombium fuliginosum Herm.; two fungal pathogens Metarhizium robertsii and Metarhizium pinghaense; the entomopathogenic nematode Steinernema carpocapsae. | ||
