Tachinid flies (Diptera: Tachinidae, Tachininae) – parasites of insect pests

The study area included 127 species of parasites from the Tachininae subfamily (Diptera: Tachinidae) belonging to 53 genera and 14 tribes. The study was conducted in 2008-2018 in Primorsky Territory. Presently the list of tachinid ies with known hosts is made up of 52 species (40.9% of the total number). The Tachininae parasitize insect orders of Lepidoptera (86.6% of the total number of species with known data), Coleoptera (9.6%), Diptera (1.9%), Dermaptera (1.9%). Among representatives of Lepidoptera, species of Noctuidae (34.1%), Lymantriidae (10.7%) and Tortricidae (9.2%) families prevail. During the study, 28 host species of tachinids ies were revealed in the Lepidoptera order which are pests of agricultural crops, park, garden and forest vegetation. These insects, in the larval stage, feed on leaves, ower buds, owers and fruits of trees and shrubs. They also damage fruit trees, park plants, sown seedlings, grain crops, basal parts and stems of vegetables. In the order of Coleoptera, Scarabaeidae family, 3 species are classi ed as pests. It is for the rst time that the information was given on parasitizing of Тachina fera L. in caterpillars Spodoptera exigua Hbn. (Lepidoptera: Noctuidae), Parhamaxia discalis Mesn . in imago Holotrichia parallela Motsch. (Coleoptera: Scarabaeidae), Hamaxia incongrua Walk. in imago Gametis jucunda (Fald.) and Anomala luculenta Er. (Coleoptera: Scarabaeidae), Mikia tepens Walk. in caterpillars Lymantria dispar L. (Lepidoptera: Lymantriidae). The study of the fauna of Tachinidae and trophic relations in the larval stage is of great scienti c and practical importance in the ght against insect pests of agriculture and forestry.
