Invasive Species News and Research, February 2020

Invasive species news from across North America. This month includes major progress in Canada, entomologists on the watch for spring pests, and much more.

Every month, new species are introduced to our lands and waters, new studies are published, and new methods of control are tested—with impacts varying across the map. It would be nearly impossible to stay on top of every piece of invasive species news.

However, the staff and board of the North American Invasive Species Management Association review headlines each month. This helps us stay on top of trends and further our mission to support, promote, and empower invasive species prevention and management in North America. We then share invasive species news most relevant for people who manage terrestrial and aquatic invasive species across the the United States, Canada and occasionally the world.

So, what happened this month?

  • Canada is doing things right, with success stories including no AIS found in Saskatchewan’s waters, research on using an invasive crab’s shell for good, and the national government recognizing National Invasive Species Awareness Week.
  • Invasive insect groups gear up for spring, from crop pest lists to a national phenology map of life-stage forecasts.
  • Research shows invasive species affect the growth of walleye.
  • These, plus much more! Read on:

Detection, Management and Control

To aid in optimizing control of insect pests of trees, the USA National Phenology Network (USA-NPN) developed models to create maps that predict the emergence of the pests in localities throughout the U.S., such as apple maggot (Rhagoletis pomonella), for which the forecast map from July 1, 2019, is shown here.

“The most immediate benefit of the Pheno Forecast maps is in helping individuals who manage for these tree pests—tree care specialists, arborists, foresters, and natural resource managers—anticipate when they might want to take action to control the pest,” Crimmins says.
