One of the key questions we’ve had concerning bagrada bugs since it first arrived
in the desert 5 years ago is where does the small stinkbug spend it’s summers? We
obviously know where they are from September until late May; in cole crops and brassica
seed crops. However, we have never been quite sure where they go after the last
seed crop is harvested. Fortunately, we’ve learned much about the seasonal ecology
of bagrada in the past few years, and this past week I received a number of reports
from PCAs of bagrada bug adults being found in sweep net samples in cotton from
the Gila and Yuma Valleys. These recent bagrada sightings are reminiscent of reports
during the summer of 2010 when finding bagrada adults in cotton was very common
