Ruffling parrot’s feathers: the biological control of Myriophyllum aquaticum

Myriophyllum aquaticum, commonly known as parrot’s feather
Myriophyllum aquaticum, commonly known as parrot’s feather, is an invasive aquatic weed. It can have roots underwater in depths of up to 1.5 metres with shoots that appear 20-50cm above the water surface. This makes it both a submerged and emergent plant. It is native to South America but is a popular garden and aquarium…

5 UK invasive species and their impact on native wildlife

Buddleja
Invasive species are one of the main causes of biodiversity loss globally. They significantly alter ecosystems and even drive native plants and animals to extinction. Over 2,000 non-native plants and animals have been introduced to the UK, and around 10-15% have become invasive. They cost the economy over £1.7 billion every year.

Potential of parasitoid to control invasive fruit fly highlighted in study

cherry fruit trees
Drosophila suzukii, commonly known as Spotted Wing Drosophila, is an invasive fruit fly native to Eastern Asia that was accidentally introduced to the Americas and Europe in the late 2000s. It has since spread rapidly causing damage to over 150 wild and cultivated fruits like cherries, blueberries, strawberries, and even the fruits of ornamental plants.

Could Telenomus remus go global?

colourful maize varieties
The parasitoid wasp Telenomus remus has been mass released as a biological control agent against fall armyworm (Spodoptera frugiperda) in the Americas (where the pest is native) for a number of years. However, fall armyworm is now highly invasive, found across Africa, Asia, and Australia. Can the lessons learnt from its wide use in the…

Research on biological control of fall armyworm

The IOBC-Global International Working Group of Ostrinia and other maize pests (IWGO) fall armyworm sub-group is organising a virtual meeting on 16-17 March 2021. The rapid spread of fall armyworm, Spodoptera frugiperda, in Africa and Asia requires the development of new, sustainable, control methods, in particularly biological control. While many organisations worldwide are working on…

A partnership between CABI and Astral-Aerial is piloting the use of drones for the control of desert locust (Schistocerca gregaria). Funded by UK Foreign, Commonwealth and Development Office (FCDO) through the Frontier Technologies Hub, the approach targets roosting populations of small swarms that are not feasible to spray by other means such as aircraft, or…

We know that invasive species – whose introduction and spread threaten biodiversity – disproportionately affect communities in poor rural areas who depend on agriculture and natural resources for their livelihood. But do gender roles and relationships in agriculture influence the way men and women experience the impact of invasive species?
