Goal. To identify the main ways of getting into the country of invasive species brown marble bug Halyomorpha halys Stål. Methods. Analytical study of information messages to the European and Mediterranean organization of plant protection (of ESR) and data of phytosanitary services of the EU, literary and Internet resources. Results. Provides information on new economically important species Halyomorpha halys Stål., which is rapidly spreading in Europe. In Ukraine, the marble bug has the status of a quarantine, but there is a risk of further spread. His first appearance on the territory of our country has registered in 2018 Threat of invasive species, a polyphage, which causes significant damage to agricultural, forest and decorative cultures. Pest can cause damage to fruit, berry crops, vineyards, beans, soy, corn, and weeds. The list of host plants includes over 300 species of plants from 49 families, however, the preference for Halyomorpha halys gives the members of the family Rosacea. Danger of falling of the pest in Ukraine of the European countries of planting material, plant products, wood packaging materials, Luggage etc. The absence of natural enemies promotes the active dispersal of the pest. The focus should be directed on the study of natural brown marble bug. The rapid spread of Halyomorpha halys in the EU countries is of great concern to scientists. The experience of foreign scientists shows that effectively regulates its abundance parasitoid Trissolcus japonicas (Ashmead) and entomoparasitic fungus Beauveria bassiana. Conclusions. There is an active resettlement of the pest in Europe. There is a risk of introduction and spread of the species Halyomorpha halys Stål, is a threat to the country.

Continued range expansion into physiologically challenging environments requires invasive species to maintain adaptive phenotypic performance. The adrenocortical stress response, governed in part by glucocorticoid hormones, influences physiological and behavioural responses of vertebrates to environmental stressors. However, any adaptive role of this response in invasive populations that are expanding into extreme environments is currently unclear. We experimentally manipulated the adrenocortical stress response of invasive cane toads ( Rhinella marina ) to investigate its effect on phenotypic performance and fitness at the species' range front in the Tanami Desert, Australia. Here, toads are vulnerable to overheating and dehydration during the annual hot–dry season and display elevated plasma corticosterone levels indicative of severe environmental stress. By comparing unmanipulated control toads with toads whose adrenocortical stress response was manipulated to increase acute physiological stress responsiveness, we found that control toads had significantly reduced daily evaporative water loss and higher survival relative to the experimental animals. The adrenocortical stress response hence appears essential in facilitating complex phenotypic performance and setting fitness trajectories of individuals from invasive species during range expansion.

Abstract Traits that aid in the invasion process should exhibit a gradient across the expansion range in response to changing selection pressures. Aggression has been repeatedly associated with invasion success in many taxa, as it may help invaders to wrestle the resources from other species which enhances their success in a novel environment. However, aggression primarily allows individuals to overcome conspecific rivals, providing advantages in competition over resources. Agonistic prowess could therefore increase fitness at both ends of the expansion gradient. Here we review the role of aggression in range expansion of invasive species, and its potential role as a driver of range expansion. We analyze how these different mechanisms could affect trait variation in expanding and invasive populations. Specifically, we look at how aggression could help dilate the edges of a population through niche competition, as well as lead to exclusion from the center (i.e. areas of high population density) by the conspe-cifics. Both of these processes will result in a characteristic spatial distribution of phenotypes related to aggression that could provide insights into the ecological pressures and dynamics of expanding populations, potentially providing clues to their success as niche competitors and invasive species.

AbstractBrown marmorated stink bug, Halyomorpha halys (Stål), is a highly polyphagous invasive species attacking both cultivated and wild plants increasing its threat to ecosystems as a global pest. However, dispersal biology of this invasive species is not well understood. This study evaluated the flight capacity and behavior of H. halys under laboratory, semi-field, and field conditions. Flight mills were used to measure the baseline flight capacity of adults collected year round from the field and included both foraging and overwintering populations. The effects of abiotic conditions such as wind speed and temperatures on the free flight parameters of H. halys were evaluated under semi-field and field conditions. The mean flight distances over a 22-h period were 2442 and 2083 m for male and female, respectively. Most individuals (89%) flew <5 km, though some flew much further with a maximum flight distance observed of 117 km. Flight distances by H. halys increased after emergence from overwintering sites in spring and reached their highest point in June. The incidence of take off by H. halys was significantly affected by the wind speed; when provided with still air conditions, 83% of individuals took off, but the rates decreased to <10% when wind speed was increased to or above 0.75 m s−1. The incidence of take off by H. halys was significantly affected by ambient temperature and light intensity in the field, whereas relative humidity and insect sex did not. When the temperature was at 10–15°C, 3% of individuals took off, but the proportion of H. halys taking flight increased to 61, 84, and 87% at 15–20, 20–25, and 25–30°C, respectively. In the field, prevailing flight direction was biased toward the opposite direction of the sun's position, especially in the morning. The implications of H. halys flight biology are discussed in the context of developing monitoring and management programs for this invasive species.
