" This paper presents the species composition and abundance of epigeal invertebrate fauna collected
from experimental pepper crops at the Vegetable Research and Development Station Buzău, Romania during
219-2020. The open field bell pepper Buzau 10 (2019) and Cantemir (2020) varieties were used in the
experiment in five variants with two factors, diatomite (three doses) and bioinoculant Trichoderma asperellum
Td85 strain. Diatomite was local from the Pătârlagele deposit (Buzău County) and antagonistic fungus was from
the collection of microorganisms of Research and Development Institute for Plant Protection Bucharest. The
fauna on the soil surface was collected using Barber traps, replaced every two weeks from June to October. The
ecological parameters of abundance, dominance, constancy and ecological significance have been calculated
using specific formulas. Specific attributes of the two products, diatomite and bioinoculant Trichoderma,
reflected on the ecological and structural characteristics of invertebrate communities."
