Assessing larval rootworm behaviour after contacting maize roots: impact of germplasm, rootworm species and diapause status
Corn rootworms (Chrysomelidae: Diabrotica spp.) are widespread maize (Zea mays L.) pests that can cause economic damage by consuming plant tissues, thus negatively affecting plant physiology and function (Riedell 1990; Riedell and Reese 1999), and grain yield (Sutter et al. 1990; Spike and Tollefson 1991). The majority of plant damage is caused by the subterranean larval stages, which can also ...
متن کاملA selective insecticidal protein from Pseudomonas mosselii for corn rootworm control
The coleopteran insect western corn rootworm (WCR, Diabrotica virgifera virgifera) is an economically important pest in North America and Europe. Transgenic corn plants producing Bacillus thuringiensis (Bt) insecticidal proteins have been useful against this devastating pest, but evolution of resistance has reduced their efficacy. Here, we report the discovery of a novel insecticidal protein, P...
متن کاملNovel Bacillus thuringiensis binary insecticidal crystal proteins active on western corn rootworm, Diabrotica virgifera virgifera LeConte.
A new family of insecticidal crystal proteins was discovered by screening sporulated Bacillus thuringiensis cultures for oral activity against western corn rootworm (WCR) larvae. B. thuringiensis isolates PS80JJ1, PS149B1, and PS167H2 have WCR insecticidal activity attributable to parasporal inclusion bodies containing proteins with molecular masses of ca. 14 and 44 kDa. The genes encoding thes...
متن کاملRNAi as a management tool for the western corn rootworm, Diabrotica virgifera virgifera.
The western corn rootworm (WCR), Diabrotica virgifera virgifera, is the most important pest of corn in the US Corn Belt. Economic estimates indicate that costs of control and yield loss associated with WCR damage exceed $US 1 billion annually. Historically, corn rootworm management has been extremely difficult because of its ability to evolve resistance to both chemical insecticides and cultura...
متن کاملEstimation of efficacy functions for products used to manage corn rootworm larval injury
Maize, Zea mays L., is an economically important crop grown throughout the world. Corn rootworm, Diabrotica spp. (Coleoptera: Chrysomelidae), larvae constitute a significant economic threat to maize production in the United States, where yield losses and management costs associated with corn rootworm species exceed $1 billion annually. Furthermore, the introduction of the western corn rootworm,...
