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…

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…

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…

Controlling the invasive blackberry on the Galápagos Islands

The unique wildlife and farmland on the Galapagos Islands are threatened with a non-native invasive weed. The invasive blackberry now covers around 30,000 hectares and can grow up to 3 metres tall. CABI scientists are searching for potential biocontrol agents from the Asian native range of the blackberry to introduce…

Toolkits for invasive plants in East Africa

Many plants introduced to East Africa have escaped cultivation and are wreaking havoc. These invasive species are reducing biodiversity and negatively impacting livelihoods. Little is known about the number of invasive plant species present here, or their impact. This project aims to use communication technologies to improve the ability of…

Measuring the livelihood impacts of invasive alien species in East Africa

Although a lot is known about the biodiversity impacts of introduced species in East and southern Africa, very little is known about the livelihood impacts that they have on communities that depend on the goods and services provided by ecosystems. The aim of this project is to determine the negative…
