Goal. The article presents the results of studies conducted in 2023—2025 on the effectiveness of neonicotinoid–pyrethroid insecticides in protecting winter oilseed rape (Brassica napus oleifera bienis D.C.) for controlling the population density of Ceutorhynchus assimilis Payk.
Methods. The research was carried out on the winter oilseed rape variety Veritas at SТОV «Rozdilnianske», Rozdilnianskyi District, Odesa Region. The identification of species composition and the assessment of phytophagous insect population dynamics were performed using route surveys according to generally accepted entomological methods.
Results. It was established that the most harmful pest was the seed weevil (Ceutorhynchus assimilis Payk.), which significantly reduced both yield and seed quality. Among the tested insecticides, the highest technical efficiency was demonstrated by Inzak Zeon, CS (acetamiprid, 200 g/L + lambda-cyhalothrin, 80 g/L), showing 68.6—88.8% effectiveness, whereas Proteus 110 OD, SC (deltamethrin, 10 g/L + thiacloprid, 100 g/L) exhibited a lower efficiency of 62.0—75.8%.
Conclusions. Weather conditions had a notable effect on the stability of insecticide performance: in 2024, the efficiency decreased due to high air temperatures (up to +29°C), while in 2023 and 2025 the insecticides performed more consistently. The study proved that the use of modern insecticides reduces pest populations below the economic threshold of harmfulness, which is essential for obtaining high and stable yields of quality rapeseed. The obtained results are of practical importance for improving the system of integrated pest management of winter oilseed rape under the conditions of Southern Ukraine.
