Dailey, P.J., R.C. Graves, and J.L. Herring. 1978. Survey of Hemiptera collected on common milkweed, Asclepias syriaca
, at one site in Ohio. Entomological News 89(7&8): 157-162.
ABSTRACT: Hemiptera frequenting 337 plants of common milkweed, Asclepias syriaca
were surveyed by daily collecting for a period of 90 consecutive days. Forty-six species are listed, some of which are probably new Ohio records. Five species were considered to be significantly abundant (more than 50 individuals collected): Lygaeus kalmii, Lygus lineolaris, Plagiogfiathus politus, Adelphocoris lineolatus
, and Cosmopepla bimaculata
. Only L. kalmii
(1,173 individuals collected) and 0ncopeltus fasciatus
, which was relatively scarce, are host specific.
