two of the MCSE systems and found rarely in others. This is most striking for
Coleomegilla maculata
that is primarily found in corn, and for
H. convergens
that
most commonly occurs in soybean. Other species like
C. septempunctata
and
Coccinella trifasciata perplexa
(Mulsant) are commonly found in multiple MCSE
systems but only rarely in others.
Role of the Surrounding Landscape
Coccinellids use various habitats in the landscape as they move from overwintering
sites to spring and summer feeding habitats. By sampling native plant communities
at the interface of woodlots and crop fields, Colunga-Garcia (1996) documented
the role of early flowering plants such as spring beauty (
Claytonia virginica
L.) and
common dandelion (
Taraxacum officinale
F.H. Wigg) in providing spring pollen
sources to adult coccinellids emerging from overwintering sites. He also developed
a model to estimate the location of overwintering sites based on the position of
woodlots and early spring pollen sources.
