Abstract
The article presents the results of testing two different types of pheromone traps for catching a dangerous quarantine pest — the brown marmorated stink bug Halyomorpha halys in the North Caucasus conditions. The data showed that the use of a small (hanging) accumulative pyramid shaped trap in hazelnut planting allowed increasing the catches of adults of Halyomorpha halys by 94 % and nymphs by 75 %, in comparison with a large (ground) accumulative pyramid shaped trap. During the trial, the conditions under which the pests nymphs and adults were actively caught in pheromone traps were determined. The main catch of nymphs — 83 % was fixed at temperatures from +20 to +25 °C, while 52 % adults — at +25...+ 30 °C. The percentage of adults and nymphs of the brown marmorated stink bug caught in the traps was about the same level and amounted to 53 % and 47 %, respectively.
