Stopping Invasive Pests

Border Surveillance for Invasive Pests

In October 2014, the USDA confirmed the interception of Phaecasiopha fernaldana Walsingham, a particularly devastating to apples fruit, apple buds, leaves and shoots. This was the first detection of this pest in the US.

This article illustrates the importance of diligent and consistent border inspections for invasive species.

Climate Change and Pest Management

At the October 2014 CAPCA Conference, a presenter predicted impacts of climate change on invasive pest management. She stated that invasive species are expected to move 1.9 kilometers away from the equator or up in altitude. Also, insect life cycles are expected to change from 2 to 5-10 life cycles in a season. We can also expect to see pest infestations become much less predictable as insect movement is erratic and life cycles are disrupted. Additionally, she discussed that climate change is expected to reduce plant nutrition, which, in turn, means that insects will need to feed more in order to sustain life. 

Additional stats: 

  • Pre-1989, California acquired 6 new invasive species per year.
  • Post-1989, California acquires 10 new invasive species per year.
  • Invasive species cost the US about $138 billion per year.
  • Invasive species cost CA > $34 billion per year.
