Biological control of diamondback moth in Canada
The diamondback moth is a global pest. Canadian farmers often have use chemicals to protect their crops. This is costly and the pest is becoming immune, meaning additional control options are needed. In Europe, Asia and Africa, Diadromus collaris, is a major parasitoid of the moth. It has been introduced to several countries or regions and has established as a successful biocontrol. CABI is therefore carrying out life table studies in Europe to determine if its introduction is a viable strategy.
Researching introduced forest species in Trinidad
Many introduced species can have an adverse effect on native biodiversity, especially on a delicate island habitat such as Trinidad and Tobago. Three forest species are being particularly troubling, namely, Tectona grandis (teak), Acacia mangium (brown salwood) and Leucaena leucocephala (white leadtree). So, with funding from the FAO, CABI researched the species to find out how they behave and where they have invaded with a view to controlling them sustainably.
Invasive blackberry threatens iconic Galapagos Islands
The Galapagos National Park Directorate (GNPD) is partnering with CABI and the Charles Darwin Foundation (CDF) to help protect the iconic Galapagos Islands from an invasive blackberry (Rubus niveus). This non-native plant was introduced in 1968 and is causing serious problems for local biodiversity and agriculture. It is now considered one of the worst weeds affecting the islands.
Sentinel nurseries as early warning system against alien tree pests
Many of the alien pests and diseases of woody plants were unknown before they were established in new countries. No policy or measures to avoid their introduction and spread were therefore implemented. Recently, monitoring sentinel plants in exporting countries has been proposed as a valuable tool to identify harmful organisms prior to their arrival. This Action advances the use of sentinel plants through international collaboration of scientists and regulators.
