The order Coleoptera is considered to be the order with the most useful and predatory species. The research was carried out in the Amărăștii de Jos stationary in 2020 in solanaceous vegetable crops (peppers, tomatoes and aubergines). The proposed objectives were to know the current state of research on the useful and harmful fauna of the order Coleoptera in the crops that were studied. The study methods used were: the shaking method, the Barber trap method and the entomological net method. Determination of coleopteran entomofauna was carried out in the Entomology Laboratory of the Faculty of Horticulture within the University of Craiova using coleopteran determinant factors (Bobîrnac B., Stănoiu I., Năstase A., 1994), Chimișliu C., 2002). The insect collection was systematically classified into 6 families as follows: family Cantharidae, family Chrysomelidae, family Coccinelidae, family Carabidae, family Cetoniidae and family Scarabaeidae. In 2020, the results obtained led to the identification of 23 species belonging to the order Coleoptera, species totalling 218 specimens. Of the total number of species collected, a very large number are coleopteran pests, with only 10 useful species. Among the useful species encountered, we find: Coccinella septempunctata, Carabus violaceus, Carabus ulrichi, Adalia bipunctata, Coccinella 12-punctata, the species with the highest number of specimens is Harpalus affinis Schrank.
