Abstract

As might be expected, soybean aphid populations have increased slightly in some locations around Iowa. The most notable increases, although they have been small, were reported from northeastern Iowa by Brian Lang, extension field agronomist in Decorah. The average number of aphids per plant increased from 6.6 to 30 with the percent infested plants also increasing from 59 to 95 percent (Table 1). The population in northeastern Iowa most closely parallels the same trends from 2005 with respect to aphid numbers and percent infested plants. Fortunately, we are not yet observing a population increase that would mirror the major outbreak year of 2003, and that is good news.
