PSYLLID WATCH
F
University of Idaho program keeps tabs on winged insects
By John O'Connell
UNIVERSITY OF IDAHO
or a second consecutive year, a
University of Idaho (U of I) pest
monitoring program trapped
relatively few potato psyllids in Idaho
spud fields during 2023, but slightly
more psyllids than normal harbored
the bacterium that causes zebra chip
disease, which affects potato crops.
" Zebra chip was observed to some
extent in the field, but I have not
heard of any major disasters, " said
U of I entomologist Erik Wenninger,
who oversees the potato psyllid
monitoring program.
Potato psyllids are tiny, winged
insects that can transmit the
Liberibacter bacterium, which causes
zebra chip in spuds. In addition to
U of I's program entails placing yellow sticky traps in potato fields throughout the state and
testing any captured psyllids for the presence of the Liberibacter bacterium.
affecting plant health and reducing
yields, the disease creates bands
through tuber flesh that darken when
fried, rendering the infected potatoes
unmarketable for aesthetic reasons.
U of I posts average psyllid counts
and positive tests for Liberibacter by
region throughout the growing season
at idahopestmonitoring.org, which is
a new central hub for university pest
We can talk all day about our
high quality machines for storage
and processing but...
... it's the result
that counts
