Biological control against invasive agricultural pest slows deforestation across Southeast Asia

Used as an effective method of controlling invasive species, biological control (or biocontrol) is the term given to the use of living organisms for controlling pests and invasive species. It can provide an effective, environmentally-friendly and cost-efficient way of controlling pest populations, helping to restore crop yields and farmer’s profits. However a recent study, focussing on invasive cassava mealybugs, has shown that biocontrol can also have some surprising knock-on effects.

Zygogramma bicolorata released at selected sites in Pakistan as biological control of parthenium

dsc_0409

Parthenium hysterophorus is a highly destructive weed which has invaded and is widespread in around 48 countries in Africa, Asia, and the South Pacific. In Pakistan the weed is spreading rapidly westwards and southwards across both rural and urban landscapes, affecting native ecology and harming agriculture.

CABI scientist Dr Lukas Seehausen has updated delegates at the International Soft Fruit Conference in s-Hertogenbosch, in the Netherlands, on the very latest research in the fight against the devasting fruit fly Drosophila suzukii.

Dr Seehausen, a research scientist in risk analysis and invasion ecology based at CABI’s Swiss centre in Delémont, said a biological control agent – the parasitoid Ganaspis cf. brasiliensis – could soon be released to manage the invasive pest in Europe.

Using animals in the fight against invasive species

Could honey bees (Apis mellifera) help in the fight against invasive species?

Whilst prevention is better than a cure, it is not always possible to stop every invasive species from entering an area. In these instances, early detection and rapid response are crucial, as management is much easier while the population of an invasive species remains small. Detection of small populations, however, can be incredibly difficult. With the spread of invasive species becoming an ever increasing problem around the world, it could pay to think outside the box when trying to manage them – could animals help with the fight against invasive species? Researchers and conservationists seem to think so. Continue reading

Fall armyworm radio campaign for next growing season launches in Zambia

IMG_9111

CABI in partnership with Ministry of Agriculture in Zambia through the National Agricultural Information Services (NAIS) has launched a national radio campaign focusing on the identification, prevention and management of fall armyworm. The campaign aims to help smallholder farmers in Zambia minimise fall armyworm losses and learn how to safely use chemicals.

Action on Invasives short course on classical weed biological control

Invasive species pose a serious threat to food security, biodiversity, water resources, human and animal health, and economic development. It is widely acknowledged that integrated control is the most effective strategy in managing invasive plants where it involves the use of herbicides, manual or mechanical control, and biological control agents in an integrated way. Last month, a short course on invasion biology and classical biological control of weeds was delivered at CABI in Pakistan.
