AbstractIn Canada, viticulture has been practiced since the arrival of European settlers. After a period of low activity due to the prohibition in North America, viticulture enjoyed a renaissance in the 1970s such that it became a rapidly growing industry in Canada. It is currently practiced mainly in five provinces,i.e., British Columbia, Ontario, Québec, Nova Scotia, and New Brunswick. In Eastern Canada, several species of wild vines (VitisLinnaeus; Vitaceae) grew naturally before cultivation of domesticated cultivars and these had their entomofauna. In contrast, no wild vines grew in British Columbia. As a consequence, the insect fauna varies according to the provinces and the regions and the agroclimatic conditions. Here we review the literature relevant to viticultural entomology in Canada and discuss the main grape insects. It is noteworthy that certain insect pests of grapes were the subject of the first issues ofThe Canadian Entomologist. Selected milestones are provided to document the evolution of research in grape entomology in the context of dynamic evolving viticultural and oenological industries. In recent years, the arrival of several invasive species challenged the sustainability of integrated pest management programmes.

Abstract A description is provided for Arthrinium sphaerospermum, which is most frequently encountered as a saprobe on decaying leaves and stems of plants, but is also known to live as an endophyte, for example in stems of Eucalyptus, and in the phyllosphere, for example of Iris. This fungus has also been reported as the cause of poisoning through contamination of sugarcane and the causal agent of a dermatomycosis in humans. Some information on its associated organisms and substrata, habitat, dispersal and transmission, economic impacts (positive and negative), and conservation status is given, along with details of its geographical distribution (North America (Canada (British Columbia, New Brunswick, Ontario), Mexico, USA (Georgia, Iowa, New Jersey, New York, Ohio, South Carolina, Texas)), South America (Argentina, Uruguay), Asia (Armenia, China, India (Chhattisgarh, Meghalaya, Uttarakhand), Iran, Pakistan, Russia (Sakhalin Oblast), Uzbekistan), Europe (Czech Republic, Estonia, Finland, Germany, Latvia, Netherlands, Norway, Poland, Russia (Leningrad Oblast), Switzerland, Ukraine, UK)).

Global identification and monitoring programs for invasive species aim to reduce imminent impacts to biodiversity, ecosystem services, agriculture, and human health. This study employs a 658 base pair fragment of the cytochrome c oxidase subunit I (COI) gene to identify and categorize clades of the banded grove snail (Cepaea nemoralis (Linnaeus, 1758)) from native (European) and introduced (North American) ranges using a maximum-likelihood phylogeny and haplotype networks. This work corroborates the existence of eight clades within C. nemoralis and further identified three clades that were common to both Europe and North America (A, D, O). Clades A and D were found in eastern Canada, Ontario (Canada), and British Columbia (Canada), whereas clade O was restricted to Ontario, possibly introduced from Poland or central Europe. Haplotype networks suggest clade A was introduced from northern Europe, whereas clade D was introduced from western and central Europe. Networks contained many private haplotypes and a lack of haplotype sharing, suggesting strong genetic structure in this system, possibly resulting from reduced dispersal in this species. This study describes the contemporary distribution of C. nemoralis in Canada and demonstrates the efficacy of DNA barcoding for monitoring the spread of invasive species, warranting its widespread adoption in management policies.

The geometrid moth Hemithea aestivaria (Hübner, 1789) was introduced from Europe to North America, first detected in British Columbia in 1973. Until 2019, its North American range was limited to a restricted area of the Pacific Northwest. Here, we report on the first records of H. aestivaria for eastern North America from three widely separated urban centers in eastern Canada during 2019-2020.
