Abstract:

Our research has shown that the invasive species Halyomorphahalys, found in the conditions of the Republic of Moldova in 2019, has already settled in a new area, inhabits both cultivated and ornamental plants and is able to rapidly increase the population density. The fertility of one female is 240 eggs, of which the percentage of sterility ranges from 0,4 to 3, depending on the generation. It was noted that overwintered adults in the spring-summer period show the maximum sexual activity, their fecundity is 65,7%, in the first generation the fecundity of adults was 24,3%, in the second generation – 10,1%. It was established that the period of weak sexual activity of the stink bug (the period of fruit ripening) is a period of its mass harmfulness. Research was carried out within the project of the State Program 20.80009.5107.27 “Elaboration of the alternative methods based on environmentally friendly means and procedures for harmful arthropods control in different agricultural crops”, financed by the National Agency for Research and Development.
