The original maps were adopted widely by
natural resource managers, municipal arborists,
and backyard gardeners. Based on this posi-
tive reception, the USA-NPN now offer Pheno
Forecast maps for a total of 12 pest species:
• apple maggot (Rhagoletis pomonella)
• Asian longhorned beetle
(Anoplophora glabripennis)
• bagworm (Thyridopteryx ephemeraeformis)
• bronze birch borer (Agrilus anxius)
• eastern tent caterpillar
(Malacosoma americanum)
• emerald ash borer (Agrilus planipennis)
• gypsy moth (Lymantria dispar)
• hemlock woolly adelgid (Adelges tsugae)
• lilac borer (Podosesia syringae)
• magnolia scale (Neolecanium cornuparvum)
• pine needle scale (Chionaspis pinifoliae)
• winter moth (Operophtera brumata)
The USA-NPN has made several additional
enhancements to the maps, including:
Notifications! Receive advance warning of
actionable activity for your pest of interest. Sign
up to be notified by email approximately two
weeks, and again six days, before the predicted
life cycle stage is reached at your location. Sign
up to receive notifications for any or all of the
pest maps at www.usanpn.org/data/forecasts.
Report pest activity at your site over the season.
The USA-NPN maintains Nature's Notebook, a
program for tracking plant and animal activity
over the course of the season. Tracking phe-
nology at your site can help you choose the best
time to perform management activities and
serve as an early warning indicator of trouble
brewing among your trees. Tracking phenology
of your trees and insect pests also offers edu-
cation and engagement opportunities and
supports research. You can report the status of
the Pheno Forecast pest species through Nature's
Notebook through the USA-NPN's Pest Patrol
campaign (www.usanpn.org/nn/PestPatrol). The
USA-NPN will use these observations to validate
and improve the Pheno Forecast maps. >>
Receive email-based notifications
approximately two weeks and six days prior to
when the life cycle of interest for your species
will occur at your location.
