We are receiving reports of false chinch bugs (Nysius spp.) damaging soybeans in Gage County and alfalfa in York County. These insects usually build up in the spring on winter annual weeds in the mustard family, such as penny cress. As these plants mature or are killed by herbicide in the field, the false chinch bugs migrate to nearby crops.
Often they are concentrated on field borders or on a few plants. Large numbers of false chinch bugs feeding on new growth can result in wilting and sometimes death of the portion of the plant fed upon.
If large numbers of false chinch bugs are injuring plants, often a border treatment is sufficient to control them.
Kansas State University has a good fact sheet on false chinch bugs at http://www.ksre.ksu.edu/library/entml2/mf3047.pdf
