AbstractThe cabbage seedpod weevil, Ceutorhynchus obstrictus (Marsham), was discovered infesting canola [Brassica napus L. and Brassica rapa L. (Brassicaceae)] in southern Alberta in 1995, and by 1999 its populations had reached outbreak densities. The weevil has dispersed rapidly through cropland in the southern prairies, prompting this study to assess its potential for establishment in Canada's primary region of canola production in the Moist Mixed Grassland and Aspen Parkland ecoregions. In this study, both short- (24 h) and long-term (4 years) distribution patterns of cabbage seedpod weevil were examined, and these data were combined with previously published ecological findings and meteorological data in CLIMEX™ software to predict regions of western Canada where economically important infestations are likely to occur. Adult temporal distributions over 24 h on canola in bud and flower remained restricted primarily to the inflorescence rather than on stems and leaves regardless of time of day. Surveys conducted in commercial canola fields from 1997 to 2000 recorded rapid dispersal of the species to the north and east from the region of southern Alberta where it was initially found. Dispersal occurred at a rate of approximately 55 km/year, and in 2000 C. obstrictus populations were found in Saskatchewan for the first time. The CLIMEX™ model predicts that the distribution of C. obstrictus will eventually encompass the entire region of canola production in western Canada.

Diaspora Policy

AbstractPolicy towards Hungarians living in neighbouring countries has been a central issue for Hungarian governments, yet Hungarian diaspora living mainly in Western Europe and North America have received very little attention. This has changed after the 2010 landslide victory of Fidesz. The new government introduced a structured policy focused on engaging Hungarian diaspora, largely due to the nationalist rhetoric of the governing party. The article argues that this change reflects a turn of Hungarian nationalism into what Ragazzi and Balalowska (2011) have called post-territorial nationalism, where national belonging becomes disconnected from territory. It is because of this new conception of Hungarian nationalism that we witness the Hungarian government approach Hungarian communities living in other countries in new ways while using new policy tools: the offer of extraterritorial citizenship; political campaigns to motivate the diaspora to take part in Hungarian domestic politics by voting in legislative elections; or the never-before-seen high state budget allocated to support these communities. Our analysis is based on qualitative data gathered in 2016 from focus group discussions conducted in the Hungarian community of Western Canada to understand the effects of this diaspora politics from a bottom-up perspective. Using the theoretical framework of extraterritorial citizenship, external voting rights and diaspora engagement programmes, the paper gives a brief overview of the development of the Hungarian diaspora policy. We focus on how post-territorial nationalism of the Hungarian government after 2010 effects the ties of Hungarian communities in Canada with Hungary, how the members of these communities conceptualise the meaning of their “new” Hungarian citizenship, voting rights and other diaspora programmes. We argue that external citizenship and voting rights play a crucial role in the Orbán government’s attempt to govern Hungarian diaspora communities through diaspora policy.
