Western corn rootworm (Coleoptera: Chrysomelidae; Diabrotica virgifera virgifera LeConte) emergence and abundance in transgenic cornfields with structured and seed blend refuges
… to Bt toxins, growers must plant a non-Bt “refuge” in each Bt cornfield. This allows susceptible larvae to develop without exposure to the Bt toxin(s). Matings between susceptible adults and potentially resistant adults developing on Bt plants may delay the development of Bt resistance in …

The movement behavior and reproductive ecology of western corn rootworm beetles (coleoptera: chrysomeliae) in Bt cornfields with structured and seed blend refuges
… (IRM) plan requiring the planting of non-Bt refuges as structured blocks or randomly distributed (seed blends) within Bt cornfields. Refuges allow susceptible larvae to develop without exposure to Cry proteins expressed elsewhere in the field. The modest populations of susceptible beetles …

A Study of Neonicotinoid Seed Treatments in Bt Maize: Insect Resistance Management, Efficacy, and Environmental Fate
… States (US) is treated with a neonicotinoid seed treatment (NST), and transgenic (GMO) maize, Zea mays L. (Poaceae), that produces insecticidal toxins by way of genes derived from Bacillus thuringiensis (Bt), occupies more than 75% of maize acreage. Among a variety of secondary pests targeted …
