The objective of this work was to evaluate the circadian feeding
rhythm of the green-belly stink bug (Dichelops melacanthus) on corn (Zea
mays), and to correlate it with meteorological parameters. The experiments
were conducted in corn fields in the first (summer) and second (fall) crop
seasons, in the municipality of Chapecó, in the state of Santa Catarina, Brazil.
Plants in the V3 and V5 stages were covered with cages and infested with
adults of D. melacanthus. After 24 hours of acclimation, the number of insects
feeding on the plant stem was counted every three hours (at 6:00, 9:00, 12:00,
15:00, 18:00, 21:00, and 0:00 h). At night, a red led flashlight was used to
visualize the insects without interfering with their behavior. Meteorological
parameters were monitored and correlated to the number of insects feeding on
the plants. In the first and second crop seasons, the number of insects feeding
on the corn stem differed among evaluation times, with peak in the afternoon,
in the evening, and at night. Few insects were found feeding at 6:00 and 9:00
h. There was a positive correlation between air temperature and feeding in
both seasons. In milder temperature regions, the preferred feeding time of D.
melacanthus on corn is during the afternoon, evening, and night hours, which
should be taken into account for a precise management of this insect. |
