Background. Lepidoptera (Lepidoptera) is a species-rich genus of insects. 180,000 species belonging to 4,200 genera from 128 families have been registered in science. A significant part of the taxa form the noctuidae family, which currently includes about 35,000 species. Representatives of several genera of moths are widespread in legume agrobiocenosis, in particular, gamma moth, large wax moth, burdock. The insect fauna of vegetable and melon crops was periodically studied in the Fergana Valley. Including T. Tursunkhodjaev in 1960-70s on the territory of Eastern Fergana [3; pp. 49-54.], Although I. Zakirov compiled a list of species for the Central Fergana region, pea agrobiocenosis was not included in this list  [1; pp.41-51.].

Methods. The research materials were collected in the period 2010-2023 from chickpea plants grown on farms and household plots in all districts of Namangan region and adjacent territories located in the northern part of the Fergana Valley.

Result. Nevertheless, phytophages collected in pea agrocenosis of Northern Fergana were recorded and counted at different times of the year.

As a result of research conducted in 2010-2023, it was found that in the agrobiocenosis of pea in Northern Fergana there are 44 species of insects belonging to 6 genera of 21 families of 36 order. Of these, 6 species were representatives of moths. Their classification list, distribution, feeding peculiarities are given below.
