Recruitment of entomopathogenic nematodes by insect-damaged maize roots
The first identification of an insect-induced belowground plant signal, (E)-β-caryophyllene, which strongly attracts an entomopathogenic nematode, is reported, which should help enhance the efficacy of nematodes as biological control agents against root pests like D. virgifera. Expand
Parasitoids, predators and PCR: the use of diagnostic molecular markers in biological control of Arthropods
Research that has used PCR‐based techniques for parasitoid and predator/prey identification and detection is reviewed, and these studies are placed in the context of their contributions to biological control of arthropods. Expand
Selection of non-target species for host specificity testing.
It is proposed that a set of categories, including ecological similarities, phylogenetic/taxonomic affinities, and safeguard considerations are applied to ecological host range information to develop an initial test list to reduce the number of species to be tested. Expand
Constructing life‐tables for the invasive maize pest Diabrotica virgifera virgifera (Col.; Chrysomelidae) in Europe
Complete age specific life‐tables were constructed in two maize fields in southern Hungary assessing the significance of natural mortality factors acting on D. v. virgifera populations to provide a rational basis for devising sustainable integrated pest management programmes. Expand
Comparative assessment of the efficacy of entomopathogenic nematode species at reducing western corn rootworm larvae and root damage in maize
All tested EPN species significantly reduced damage on maize roots independently, whether they were applied at sowing or in June, however, damage was not totally prevented and the use of H. bacteriophora for the development of a biological control product for inundative releases against D. v. virgifera larvae is suggested.

Methods Used to Assess Non-target Effects of Invertebrate Biological Control Agents of Arthropod Pests
This review provides an overview of methods currently applied in the study of non-target effects in biological control of arthropod pests, and provides the first step towards the ultimate goal of devising guidelines for the appropriate methods that should be universally applied for the assessment and minimisation of potential non- target effects.

Comparative assessment of the parasitoid community of Delia radicum in the Canadian prairies and Europe: A search for classical biological control agents ☆
Abstract As a precursor to a classical biological control programme for Delia radicum in spring-seeded (“summer”) canola (oilseed rape) in Canada, communities of parasitoids of D. radicum in summerExpand
Actual and potential distribution of an invasive canola pest, Meligethes viridescens (Coleoptera: Nitidulidae), in Canada
Abstract Meligethes viridescens (Fabricius), bronzed or rape blossom beetle, is a widespread and common pest of oilseed rape [Brassica napus L. and Brassica rapa L. (Brassicaceae)] in the westernExpand
