Ecological diversity is an important parameter in assessing the state of an ecological system. This paper presents the results of a study conducted in 2019-2020 on the abundance and ecological diversity of useful and harmful insect communities from an experimental crop of bell pepper organized at the Research-Development Station for Vegetable Growing Buzău. The experiment included five variants in four replications disposed in completed randomized block, untreated, diatomite in three doses (52.5 g, 105 g, 210 g) and Trichoderma asperellum Td85 strain. The diatomite is of autochthonous from the Pătârlagele deposit and the antagonistic fungus Trichoderma from the microorganism collection of the Research and Development Institute for Plant Protection Bucharest. Samples were collected every two weeks by the Barber soil trap method. Data collected in experimental crop of bell pepper under this study revealed a total of 1,455 individuals in 2019 and 1,634 in 2020, respectively, belonging to 124 species, 104 genera, 58 families, 17 orders, 8 classes and 3 phyla. The ecological diversity of present species was estimated using the diversity indexes, Margalef, Menhinick, Shannon-Wiener and Simpson.
