Responses of transgenic maize hybrids to variant western corn rootworm larval injury
TL;DR: It is hypothesize that the variant western corn rootworm may be able to inflict more root injury to these transgenic insecticidal maize hybrids than the non‐variant population of this species.

McCornack,Rouf Mian,Matthew E. O'Neal,Vaino Poysa,Deirdre A. Prischmann-Voldseth,David W. Ragsdale,Nick Tinsley,Dechun Wang +17 more
TL;DR: Several factors may have contributed to the variability, including genetic diversity of soybean aphids, parthenogenicity, abundance of the overwintering host buckthorn (Rhamnus spp.), and migratory patterns of soy - bean aphids across the landscape.

Evaluation of adult emergence and larval root injury for Cry3Bb1‐resistant populations of the western corn rootworm
TL;DR: Results suggest that Cry34/35Ab1‐expressing Bt maize may represent a valuable option for maize growers where Cry3Bb1 resistance is either confirmed or suspected, and suggest that improved decision‐making for insect resistance management is needed to ensure the durability of BT maize.

TL;DR: A meta‐analysis is performed to provide a broad understanding of the relative efficacy of the primary products currently being used to manage corn rootworm larval injury, including insecticidal seed treatments, soil insecticides and Bt hybrids (with and without the addition of soil insecticide).
Effect of Seed Blends and Soil-Insecticide on Western and Northern Corn Rootworm Emergence from mCry3A + eCry3.1Ab Bt Maize

TL;DR: Both western and northern corn rootworm beetle emergence from all Bt treatments was significantly reduced, and time to 50% beetle emergence in the 100% mCry3A + eCry3.1Ab treatment with Force CS was delayed 13.7 d, which is significant in terms of rootworm resistance management.
