Improving knowledge and understanding of beetle biodiversity in Laos
Global biodiversity is receiving increased attention as it becomes more and more threatened because of the growing human population and development. Beetles or coleopteran are no exception and CABI is running this project to increase knowledge and understanding of their biodiversity in Laos.
Biological control of apple leaf-curling midge in Canada
A European biological control agent may help control an exotic pest of apple trees in western Canada. Damage from the apple leaf-curling midge in eastern Canada was effectively reduced by introducing a European natural enemy, Platygaster demades, in the 1990s. The pest arrived in British Columbia more recently, where releases of P. demades are now being considered. First, however, the identity of P. demades needs to be confirmed with molecular tools and its host range defined.
Using beneficial maize-rhizosphere microbials against western corn rootworm
The western corn rootworm is a major invasive maize pest in North America and Europe. The phase-out of certain pesticides means control options are increasingly limited. New technologies are being researched in collaboration with five French partners. Using field surveys and candidate gene searches through database-mining, we are investigating bacterial proteins with insecticidal effects. Promising strains are then screened in vitro to develop biopesticidial or biotechnological control options.
Research, rearing and collection services on corn rootworms
The western corn rootworm is a destructive pest of maize. Most damage is caused by larvae feeding on the roots, which becomes apparent when plants lodge. Drawing on some 15 yearS experience as a research and development partner on corn rootworms, CABI has become a key service provider for field surveys, laboratory and field research on basic ecology and management of the pest, rearing including supplying eggs for research, and writing support.
Action on Invasives
The global cost of invasive species is estimated at US$1.4 trillion per year – close to 5% of global gross domestic product. Invasives disproportionately affect vulnerable communities in poor rural areas, especially in developing countries which depend on natural resources, healthy ecosystems, trade and tourism for their livelihoods.
Biological control of hawkweeds
European hawkweeds are invasive in North American pastures, where mechanical methods of control are difficult and ineffective. Chemical control with broad-spectrum herbicides is not selective and relatively expensive, with the weed often recolonising untreated pastures. Insects that feed on hawkweeds in Europe have been studied as potential biological control agents for North America since 2000. Two agents have been released in North America – the gall wasp, Aulacidea subterminalis, and the hoverfly, Cheilosia urban.
