Kudzu Bug Collected In Christian County, Ky.
PRINCETON, KY.
A single adult Kudzu bug was collected on June 16, 2014 from a Kudzu
patch located at near KY mile marker #1 on the north-bound right-of-way
of I-24 (Christian County). No nymphs or eggs were collected. This
represents the first confirmed occurrence of this invasive pest in the
western Kentucky grain crops production area.
The bug was collected with a 15-inch sweep net in the first 20-sweep
subsample of the first 100-sweep sample taken at this location.
Subsequently, four more 100-sweep samples were taken with no further
Kudzu bugs found. Clearly this is not a large infestation. Additionally,
this location is relatively isolated from soybean fields, and is
bordered by pasture.

It is unlikely that this find represents the beginning of an
economically important infestation for 2014. Nevertheless, it does tell
us that this location, which is about 200 to 300 yards north of the
acceleration ramp coming out of a rest stop, is likely to be infested
repeatedly from vehicles traveling at slow speeds as they merge into
I-24 traffic. I will not be at all surprised if the population increases
through the summer. These are still early days for this bug in our
area.
We are very fortunate that the Christian County agriculture agent has
located a producer that has soybeans planted very near the deceleration
ramp leading into the rest area. I also sampled that field and did not
detect any Kudzu bugs. I am much appreciative to the producer for
allowing me access to this field. I will continue to sample over the
summer as time permits. ∆
