Abstract

Soybean aphid populations remain at low densities in monitored fields across the state, but the known distribution for 2006 now covers most of Iowa. On June 19, Extension field crops specialists reported soybean aphids from northeastern (Allamakee, Clayton, Winneshiek counties), southeastern (Lee County), central (Story County), and northwestern Iowa (Cherokee County). Aphid densities were less than one aphid per plant in all counties. In the June 5 newsletter, we reported an aphid colony containing 40 insects, but two weeks later when 80 plants were inspected in the same field, only a single plant was found with only four aphids on it.
