Western corn rootworm (Coleoptera: Chrysomelidae; Diabrotica virgifera virgifera LeConte) emergence and abundance in transgenic cornfields with structured and seed blend refuges
… as blocks at the west end of each plot or as seed blend refuges. The spatial and temporal distribution of western corn rootworm emergence and live collected adults were analyzed in four refuge treatments (20% structured refuge, 5% structured refuge, 5% seed blend refuge and 0% refuge). …

The movement behavior and reproductive ecology of western corn rootworm beetles (coleoptera: chrysomeliae) in Bt cornfields with structured and seed blend 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 from the refuge are expected to disperse across …

Examining the effects of seed mix diversity and composition, biochar application, seeding rate, species identity, and topography on Palouse Prairie restoration
… Palouse prairie restoration methods is sparse. Seed-based restoration uses a mix of seeded species to enhance competition against weeds, diversify vegetation, and adapt to environmental conditions. However, many factors can be varied, such as seed mix diversity and composition, the proportion of …

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 …

Modeling insect resistance to transgenic corn and cowpea
… of resistance was delayed equally well by both seed-blend and block refuges with the same proportion of refuge. The results showed that Bt-pollen drift has little impact on the evolution of Bt resistance in O. nubilalis. However, low-toxin expression in ears of transgenic corn can reduce the …
