Saving Tristan’s only native tree and its associated unique buntings
Invasive non-native species are a major threat on oceanic islands due to their vulnerability and endemism, typical of island ecosystems. On Tristan da Cunha, a remote group of islands in the South Atlantic, Brown soft scale, (Coccus hesperidum), an invasive alien scale insect, has infested Tristan’s only native tree, Phylica arborea; and is now threatening the extinction of one of Britain’s rarest bird species, Nesospiza buntings. There is, therefore, an urgent need to find an appropriate method to mitigate the impact of the scale insects and prevent the total collapse of the Phylica forest. The aim of this project is to select and safely test suitable biocontrol agents to reduce scale numbers below a damaging threshold and safeguard Tristan’s endemic buntings.
Helping to achieve sustainable agriculture in Myanmar
The agriculture sector in Myanmar is predominantly dominated by rice. It is a key commodity for domestic food security as well as a generator for export income, and in the future could have the potential to become a global rice supplier. However, Myanmar is susceptible to crop losses from pests, disease and insecticide misuse. CABI is working with scientists in Myanmar to promote green agriculture practices.
Proactive biocontrol of Spotted Lanternfly
The spotted lanternfly is an Asian polyphagous pest that feeds on more than 70 plants by sucking the sap out of from leaves, stems and trunks. It was found in Pennsylvania in 2014 and has since expanded its geographical distribution. The damage caused by the pest, its sugary excrement and sooty mold has been devastating for the Pennsylvania wine industry – reportedly causing a 90% grape loss.
Improving the livelihoods of smallholder maize farmers around the Mekong
After rice, maize is the most important crop in the Mekong Delta. Insects including the Asian corn borer are a major threat to production. Fear of crop losses, together with a lack of alternative measures, can result in overuse of pesticides – posing health risks to farmers, consumers and the agro-ecosystem. This project will establish local production of an affordable biological control agent, the parasitic wasp trichogramma, which kills the eggs of maize pests.
Legacy of AgriTT programme lives on at Rwandan biocontrol facility to fight crop pests
The legacy of the Working in Partnership for Agricultural Technology Transfer (AgriTT) programme, funded by the UK Department for International Development (DFID), is living on at a facility in Rwanda which is producing biological control agents to kill a variety of crop pests including the devastating fall armyworm.
CABI study identifies safer options for fall armyworm control in Africa
CABI’s experts in the biological control of agricultural pests and diseases have conducted the first major study of potential biological controls that could be used in the fight against the devastating fall armyworm which recently arrived in Africa.
