RECENT RESEARCH ON THE WESTERN CORN ROOTWORM Western corn rootworm ( Diabrotica virgifera virgifera LeConte) population dynamics
1 The western corn rootworm Diabrotica virgifera virgifera LeConte is a major insect pest of field maize, Zea mays L. Larvae can cause substantial injury by feeding on maize roots. Larval feeding may destroy individual roots or root nodes, and reduce plant growth, stability, and yield. Costs associated with managing corn rootworms in continuous maize are annually one of the largest expenditures...
متن کاملRECENT RESEARCH ON THE WESTERN CORN ROOTWORM Behaviour and ecology of the western corn rootworm ( Diabrotica virgifera virgifera LeConte)
1 The western corn rootworm (WCR) is a historic pest with a legacy of resistance and behavioural plasticity. Its behaviour and nutritional ecology are important to rootworm management. The success of the most effective and environmentally benign rootworm management method, annual crop rotation, was based on an understanding of rootworm behaviour and host – plant relationships. Enthusiastic adop...
متن کاملPossibilities for biological control of the western corn rootworm, Diabrotica virgifera virgifera LeConte, in Central Europe
The western corn rootworm, Diabrotica virgifera virgifera, was introduced to Europe from North America in the early 1990s. It spread rapidly from its site of introduction in Serbia and is now found over some 400,000 ha of southeastern Europe. The prospects for its classical biological control by introduction of natural enemies, including pathogens, nematodes and insects, from its area of origin...
متن کاملGenome Sequence of the First Coleopteran Iflavirus Isolated from Western Corn Rootworm, Diabrotica virgifera virgifera LeConte
The genome sequence of a novel iflavirus was identified from the transcriptome of the western corn rootworm, Diabrotica virgifera virgifera The RNA sequence consists of 9,823 nucleotides (nt) with a 3' polyadenylated tail, containing a single open reading frame that encodes a 3,028-amino-acid polyprotein.
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...
