Abstract. In 2018 (1st and 2nd decades of July), the efficiency of two designs of light traps with superbright LEDs was tested on the production fields of sunflower in the central zone of the Krasnodar Krai (Dinskoy district). The experimental area was 60 ha. Traps were set at a distance of 100 m and were controlled automatically using the built-in photo relay. Species diversity was assessed using the Margalef index; the dominance was assessed using the Berger-Parker index. For the two weeks of the experiment, more than 27 thousand specimens of insects belonging to 7 orders and 16 families were captured. Calculating the absolute number of captured insects we did not reveal any significant differences between conical and aspiration traps. For the period of the experiment, the value of this indicator was 12434 and 15224 individuals, respectively. Mathematically significant differences between traps of different structures were revealed when determining the biodiversity of arthropods; the assessment of the species dominance did not reveal any significant differences. The value of the Margalef index showed the ability of a conical light trap to attract a larger number of insect species. The most attractive traps with a component share of above 91% turned out to be traps for representatives of the order Lepidoptera. Their efficiency was relatively high for the order Coleoptera (more than 8%). The proportion of representatives of other taxa was less than 0.2% of the total number. The largest part of the collections accounted for by the butterflies of the Noctuidae family. The low attractiveness of traps for the order Hymenoptera was revealed. This allowed combining their use in the system with the use of entomophages.
