Fall armyworm could cost Africa $2bn+ in lost harvest
Last week, CABI confirmed that since it arrived in Africa in 2016, the Fall Armyworm (FAW) has been reported in 28 African countries, presenting a now permanent agricultural challenge for the continent. FAW mainly affects maize and can cut yields by up to 60%. In research funded by the UK’s Department for International Development (DFID), CABI…
Side event on fall armyworm at AGRF 2017 [livestream]
In 2016 the fall armyworm, a major pest in the Americas, was found in Africa for the first time. Since then it has rapidly spread across much of sub-Saharan Africa. The caterpillar feeds on more than 80 different plants, but maize is its preferred host, the most widely grown crop in Africa and a staple…
The Life Cycle of Fall Armyworm
The Fall armyworm, Spodoptera frugiperda, is a major invasive pest in Africa. It has a voracious appetite and feeds on more than 80 plant species, including maize, rice, sorghum and sugarcane. Another feature which makes it an incredibly successful invasive species is its ability to spread and reproduce quickly. CABI have developed a poster to…
Removal of invasive shrub could be an easy way to help reduce malaria transmission
Removing the flowers of an invasive shrub from mosquito-prone areas might be a simple way to help reduce malaria transmission, according to a new study published in the open access Malaria Journal. Removing the flowers from villages in Mali decreased the local mosquito vector population by nearly 60%. The study, carried out in the Bandiagra…
CABI leads rapid identification of Fall Armyworm
Identifying armyworms usually involves taking the larvae that have caused the damage, waiting for them to develop in to adults and then studying the body and markings of these adults to identify the species collected. This process causes delays to identification, and could therefore delay action for what are some of the most ravaging crop…
Five invasive pests cost African economy $1 billion every year
New research by CABI reveals that just five invasive alien species are causing US$0.9 – 1.1 billion in economic losses to smallholder farmers across six eastern African countries each year, equating to 1.8% – 2.2% of total agricultural GDP for the region. These losses are expected to grow to $1.0 – 1.2 billion per year…
South-South collaboration helps in the fight against invasive pests
Invasive species cause widespread devastation and huge economic losses to smallholder farmers across the world, especially in sub-Saharan in Africa. Invasive species not only directly undermine farmer’s ability to achieve food security, they also affect smallholder agribusiness making farmers unable to link to profitable food value chains and international agricultural trade networks.
Scientists discover new crop-destroying Armyworm is now “spreading rapidly” in Africa
New research announced today by scientists at CABI confirms that a recently introduced crop-destroying armyworm caterpillar is now spreading rapidly across Mainland Africa and could spread to tropical Asia and the Mediterranean in the next few years, becoming a major threat to agricultural trade worldwide.
Pakistan’s papaya pest squashed through biocontrol
By Saleem Shaikh. Reblogged from SciDev.Net A severe infestation of the papaya mealybug (Paracoccus marginatus) nearly wiped out papaya orchards in Pakistan before the largely farmed country decided to replace conventional chemical pesticides that were ineffective with natural predators that proved to be successful. The system was developed by agro-biotechnologists and entomologists at the Pakistani chapter…
Plantwise showcases open access Knowledge Bank at global open data summit
Last week, CABI and Plantwise representatives attended the GODAN Summit in New York, the largest event ever planned for open data in agriculture and nutrition. It brought together key stakeholders from around the world to consider how open data can help achieve Zero Hunger – one of the key Sustainable Development Goals (SDG2). Speaking at the…
