The field trials of two types of light traps in natural and agroecosystems were carried out during August 03 to 17, 2018 at “Kuban Canned Food” Company Dinskaya district and from June 18 to August 18, 2019 at Peasant Farm Kalininsky district of Krasnodar region, Russia. The two-year dynamics of the activity of some insect species adults in the sunflower cenosis was investigated based on the results of their attraction to traps. The traps were set in three replicates, the counts were carried out once every 3–5 days, the values of the biological diversity and dominance indices of Magralef and Berger -Parker.The results obtained make it possible to draw conclusions about the general biodiversity of insects in the agroecosystem, the population density of certain species, and the dynamics of their seasonal activity. During the research period the conical trap collected representatives of 40 families, the aspiration trap of 29 insect families. In general, more families were captured with the conical light trap compared to the aspiration one. According to research data, the aspiration design of the light trap is more effective in attracting members of the Noctuidae family.
