4. Discussion
Generalist predators can exert strong top-down popula-
tion regulation of
A. glycines
in soybean
W
elds (
Costa-
magna and Landis, 2006
).
Harmonia axyridis
is one of the
most abundant predators found in soybean across the inva-
sive range of
A. glycines
(
Fox et al., 2004; Rutledge et al.,
2004; Costamagna and Landis, 2006
), thus understanding
its role in shaping the
A. glycines
predator guild is of critical
importance in the overall suppression of this invasive
species.
