The research paper presents data on the particularities of the spreading Leguminivora glycinivorella within the field, the degree of damage to various soybean varieties of Russian selection by this pest, as well as calculations of the economic threshold of harmfulness based on current data. Pest infestation of crops occurs from the near edge part; maximum density is achieved in a zone of 10-20 m from the edge of the field. The most susceptible to pest infestation are pods of varieties with a growing season of up to 102 days, and varieties with a growing season of more than 122 days are the least vulnerable. L. glycinivorella reaches the economic threshold of harmfulness at 10.5-13.4% of infected pods, provided that a seed soybean yield is obtained, as well as when obtaining vegetable soybean that is used for food in pods. The use of insecticides in the cultivation of soybean, intended for processing, is inadvisable at any level of reproduction of the pest.
