Abstract
One of the most relevant methods for monitoring insects in the practice of plant protection is the chemoregulatory method, the means of which are pheromones, hormones, attractants, repellents, etc., intended to identify phytophages and assess the level of population density on agricultural crops. The aim of the research was to carry out comparative tests of new and improved pheromone traps and preparations for monitoring the dominant grape pest – European grape moth (Lobesia botrana Den. Et Schiff.) and the invasive quarantine species - brown marmorated stink bug (Halyomorpha halys Stаl.) in the vineyards of Crimea. The work was carried out in the conditions of 2020 according to the methodological approaches used in national and international practices of entomological research on industrial plantations of the main viticulture zones of Crimea. It was found that with an average flight intensity of butterflies of European grape moth of the I generation in the vineyard of ‘Cabernet-Sauvignon’ cultivar, experimental pheromone traps of Delta, Romb and Quadro types produced by FSBI VNIIKR showed similar values of catching capacity: at the average rate of 826–1042 nos. / trap. Delta was defined as the most promising trap. Against the background of an average and low flight intensity of European grape moth butterflies of the I-III generations in the vineyards of three zones, similar level of biological activity of four pheromone preparations produced by JSC Shchelkovo Agrokhim (difference - 0.3-3.1%) was established on propylene foil (1, 5 mg of pheromone) and tube dispensers (0.8-3.0 mg of pheromone). A sufficient level of efficiency of propylene foil dispensers was shown during four months (a decrease in biological activity by 4–14%). Against the background of a low number of brown marmorated stink bugs in the vineyards, a higher (5.2 times) biological activity of the
preparation with pheromone and attractant of JSC Shchelkovo Agrokhim production in comparison with the preparation containing only pheromone was established. Using of these pheromone preparations in barrier-type traps made it possible to reveal for the first time a new quarantine bug species in the plots of two Crimean viticultural zones.
