AbstractInvasive species with distributions that encompass much of the North American environment often demand a range of management approaches, for several key reasons. Firstly, the North American environment includes a large number of highly variable habitats in terms of climatic, edaphic, and landscape features. Secondly, these regional habitat differences are accentuated by jurisdictions within Canada and the United States, whereby approaches and available resources differ at local, regional, and national scales. Another important consideration is whether an invasive species or complex also possesses genetic variation. All three of these factors render the knotweed complex in North America a highly variable target for management. In this paper we review existing knowledge of the variable nature of knotweed species (Fallopia japonica (Houtt.) Ronse Decr., Fallopia sachalinensis (F. Schmidt ex Maxim) Ronse Decr., and Fallopia × bohemica, (Chrtek and Chrtková) J. P. Bailey in North America, and evaluate how herbicidal, mechanical and biological control measures must account for this genetic variation, as well as accounting for regional differences and the potential northward expansion of knotweed under climate change. The imminent release of the psyllid, Aphalara itadori Shinji as a biological control agent in North America must also navigate regional and genetic differences. Prior European experience dealing with the three knotweed species should prove useful, but additional research is needed to meet the emerging challenge posed by F. × bohemica in North America, including the possibility of glyphosate resistance. Managers also face challenges associated with posttreatment restoration measures. Furthermore, disparities in resources available to address knotweed management across the continent need to be addressed to contain the rapid spread of this highly persistent and adaptable species. Linking practitioners dealing with knotweed “on the ground” with academic research is a crucial step in the process of marshalling all available resources to reduce the rapidly spreading populations of knotweed.

Study Results

The chief aim of invasive species management is to prevent biological invasions by taking measures for suppressing or eradicating potential invaders. Biological control as a management tool is frequently implemented to reduce the population size, adverse ecological impacts, and dispersal of invasive species. The efficacy of biological control measures in managing the Perccottus glenii population was assessed in four small lakes of Lithuania. The biocontrol was carried out by introducing the native piscivorous fishes Esox lucius and Perca fluviatilis into the invaded water bodies for two successive reproductive seasons. The stocking of these fishes led to an instant reduction in P. glenii abundances, and the outcome of the repeated stocking was complete disappearance of the species from the water bodies investigated. Our study proves that native predator fishes can be successfully used for eradicating well-established P. glenii populations in small eutrophic lakes. We hope the current study results will contribute to developing risk-commensurate methodologies for the control of invasive P. glenii populations in small water bodies.

AbstractThe flee-weevil Orchestes steppensis Korotyaev (Coleoptera: Curculionidae) is a steppe eastern Palaearctic species, notable as a serious pest of elms (Ulmus spp., Ulmaceae), by feeding on the leaves (adults) or mining them heavily (larvae), especially of Ulmus pumila L. in Xinjiang, China. We have corrected the previous misidentifications of this weevil in China as O. alni (L.) or O. mutabilis Boheman and demonstrated that it is likely to be an invasive species in Xinjiang. Prior to this study, natural enemies of O. steppensis were unknown in Xinjiang. Resulting from field investigation and rearing in the laboratory during 2013–2016, seven parasitoid species were found to be primary and solitary, attacking larval and pupal stages of the host weevil. Pteromalus sp. 2 is the dominant species and also is the most competitive among the seven parasitoids, which could considered to be a perspective biological control agent of O. steppensis. Yet, the current control of this pest by the local natural enemies in Xinjiang is still currently inefficient, even though in 2016 parasitism was about 36% on U. pumila in Urumqi, so the potential for a classical biological control program against it needs to be further investigated, including an assessment of its parasitoids and other natural enemies in the native range of O. steppensis. The presented information on the natural enemies of this weevil can be also important for a potential classical biological control program against it in North America (Canada and USA), where it is a highly damaging and rapidly spreading invasive species.

Abstract. Authors. 2019. A new trophic interaction between invasive weed, its biological control agent, and local insects: a case study of Chromolaena odorata. Biodiversitas 20: 1006-1011. Invasive species have been known to cause biotic homogenization. The presence of Chromolaena odorata, an alien invasive weed, in agricultural habitat has outcompeted many crop plants. The presence of alien invasive weed creates a new trophic interaction especially with local herbivores as well as other associate insects. This study was aimed to investigate a new trophic interaction that has been established between C. odorata, its introduced biological control agent, and local insects. The research was conducted in various land-use types in both of Arjuno and Bromo mountain landscape. In each landscape, we surveyed the population density of C. odorata and its biological control agent (a gall fly, Cecidochares connexa) as well as observed the diversity and abundance of other insects associated with C. odorata. Samples were taken along the transect lines at various altitudinal gradients, from 400 to 1100 m asl. In total, 124 species of insects were found associated with C. odorata which include herbivores, parasitoids, and predators. The difference of land-use types affected the population density of C. odorata but not its herbivores (i.e. C. connexa and aphids). A new association was found between the introduced insect, C. connexa and local parasitoids. The field survey also discovered new associations between the invasive weed with local herbivores such as aphids that are found with high abundance. The aphids were found to have a symbiosis interaction with ants such as Anoplolepis gracilipes (invasive species) and Dolichoderus thoracicus. In conclusion, the ecological consequence of the presence of invasive weed species is the shaping of a new trophic interaction with local insects, even with other invasive ant species. This interaction arguably is part of an ecological process that formed an equilibrium interaction which may cause either a negative or positive impact on C. odorata.

Currently, invasive species spreading is becoming a key problem on the global scale. Scope of invasive species control get solved at governmental level in many countries; hundreds of billions dollars a year are allocated as financial support; global programs are created. For the first time, biological control of invasive species Ambrosia artemisiifolia using an introduced phytophage insect was applied in Russia (former USSR) in the 60-70s years of the 20th century and it remains a unique large-scale example until to nowadays. Ambrosia leaf beetle (Zygogramma suturalis (Fabricius, 1775) was brought to the Russian Far East for biological control of Ambrosia artemisiifolia in the 80-90s years of the 20th century for the first time, however the targeted result was not achieved. At present, Zygogramma suturalis were adapted at the Primorskii Krai in the south of the Far East, but due to climatic conditions its numbers are low and, as a result, the impact on ambrosia is minimal. The search for native insect species with capable of effectively suppressing the spread of aggressive quarantine weed in local conditions remains in the area of focus. At the moment, two species of native leaf beetles have been identified, using Ambrosia as an additional element in the diet. Climate changes and the shift of biogeographic boundaries cause the natural expansion of the areals of some East Asian insect species to the north within the Russian Far East. Bug-edge Molipteryx fuliginosa (Uhler, 1860) is one of such species. Expanding the area to the north and east, the species also corrects trophic preferences. As a result of our research in the south of Primorskii Krai, the trophic relations of Molipteryx fuliginosa were studied in the field conditions and in rearing cages. The same work was carried out in places where Ambrosia artemisiifolia were growing in a great number. For insects observing were used standard methods. As a result, firstly was established and confirmed that the bug-edge uses Ambrosia artemisiifolia as a feed plant only in select developmental stages, including imago. The feeding of larvae of IV – V ages was noted in natural conditions. The long-time Molipteryx fuliginosa development cycle on ambrosia leads to break the course of normal plant ontogenesis and causes wilting of individual organs.
