TL;DR: The ET developed here is strongly supported through soybean growth stage R5, which provides a 7-d lead time before aphid populations are expected to exceed the economic injury level (EIL) and exposes a larger portion of the soybean aphid population to selection by insecticides, which could lead to development of insecticide resistance.

TL;DR: Phenotypic and genotypic responses of land races, pure-lines, and hybrids of maize indicate that resistance to the corn leaf aphid is inherited, and multiple genes with large environmental influence might be involved in resistance.

TL;DR: How soy bean aphid impacts soybean yield, the role of biology and economics in recommendations for soybean aphid management, and the shortand long-term consequences of inappropriately timed insecticide applications are reviewed.

TL;DR: Aster yellows (AY), a disease of small grain crops caused by aster yellows phytoplasma (AYp), produces disease symptoms similar to barley yellow dwarf (BYD), and small grain production fields in Minnesota and North Dakota were surveyed to determine the incidences of AY and BYD.

TL;DR: The diagnostic-concentration glass-vial bioassays reported here will provide the foundation for an insecticide resistance monitoring program with the ability to determine practical levels and geographic extent of insecticides resistance.
