The recreational use of marijuana becomes legal across Canada today. Of course increased cultivation of Cannabis sativa will accelerate research on this species, as was highlighted in the scientific journal Nature. It will also mean the need to protect the crop against insects and other injurious organisms. One such insect is the Cannabis aphid, Phorodon cannabis. This Eurasian species was recently introduced to North America. In a recent publication, my colleagues and I brought attention to the presence of this insect in the United States and Canada, in fields and greenhouses. We also discussed its biology and taxonomy. The aphid has already caused crop damage but its full economic impact remains to be seen.
