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 pests in the world. However, scientists from CABI and Ghana’s Plant Protection and Regulatory Services Directorate have been able to speed up identification using molecular techniques to confirm the identity of fall armyworm (Spodoptera frugiperda) from the larvae alone.

Farmers are on the boil again in India. In western Maharashtra state, they have been on strike for a week in some seven districts now, spilling milk on the streets, shutting down markets, protesting on the roads and attacking vegetable trucks. In neighbouring Madhya Pradesh, curfew has been imposed after five farmers were killed in clashes with police on Tuesday. Last month, farmers in southern Telangana and Andhra Pradesh staged protests and burnt their red chilli crop.

Mr. Guze Kampinga visits the plant clinic at Dowa Turn Off with his damaged maize samples and is received by Mrs Eluby Phiri a trained plant doctor.
“I have grown about 0.8 ha of rain-fed and 0.4ha irrigated maize (Ndimba). This year a strange pest has seriously damaged my maize and almost all people in this village are experiencing the same problem. The pest started damaging the crop a few weeks after germination and has continued damaging the crop up to now. I first noticed the tips of the maize funnel chewed and stunting yet I had applied fertilizer and there was sufficient moisture. When I checked the funnel I found small caterpillars inside, which were growing very fast. Later the leaves were chewed and holes seen in the cobs, they also feed on the kernels. I have tried to control the pest to no avail”, said Mr Guze.
The FAO estimates that up to 40% of global crop yields are reduced each year due to the damage caused by pests (FAO, 2015). Crop losses have a huge impact on the livelihoods of smallholder farmers. They result in less food for them and their families and a lower income for spending on education and farming resources, including tools for the management and control of pests.
Accurate pest forecasting systems therefore need to be made available so that farmers can be warned of potential pest outbreaks that may severely damage crops. Pest forecasts enable farmers to implement prevention methods in time for them to be most effective.
Kenya has launched a campaign to control the Fall Armyworm, (FAW) which has been sighted by farmers feeding on Maize in Trans Nzoia County, Kenya. Agriculture Cabinet Secretary Mr. Willy Bett said the pest poses a serious threat to the country’s food security situation.
“Its impact will be severe given that the country is just recovering from a drought that has affected food production. This risk is heightened since Trans Nzoia is the country’s grain basket producing maize both for seed and for consumption. The government has allocated 200million Kenya shillings for the campaign and we are working with partners to help us fight this pest”. The pest is spreading fast and has been spotted in 10 other counties of Bungoma, Kakamega, Uasin Gishu, Kwale, Taita Taveta, Nandi, Makueni, Vihiga, Busia, and Kisumu.
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 over the next 5-10 years, highlighting the urgent need for coordinated responses at regional, national and international levels.
New research published in the open-access journal Global Food Security estimates the alarming level of economic losses suffered by smallholder farmers each year in eastern Africa, to a handful of species that have become damaging crop pests since their introduction to the region. These few invasive species can have devastating impacts on important staples such as maize, but also high-value crops including tomatoes, peas and green beans.
