10 years ago the Coconut Rhinoceros beetle (CRB) was first discovered on the western Pacific island of Guam. Since then, these shoe-shine black, miniature invaders have spread to all parts of the island and are laying waste to the local coconut and oil palm population. The economy, culture and ecology of Guam and other Pacific islands are intrinsically linked to the native palm species such that the rhino beetle poses a major threat. The indigenous peoples of Guam have a long history of weaving palm fronds, an artistry that is now at risk due to the rhino beetle. These trees are a symbol of tropic paradise, a motif that drives Guam’s primary industry; tourism. Continue reading
La agricultura en el Perú se ha expandido rápidamente desde el 2000. Según el Instituto Nacional de Estadística e Informatica del Perú, el Producto Bruto Interno agrícola se ha más que duplicado entre 2000-2016. Este crecimiento estuvo relacionado a la ocupación de nuevas áreas agrícolas, pero aún por la diseminación de tecnología. El rápido acceso a insumos igualmente ha expuesto a los agricultores a intoxicación debido a una mala utilización de los mismos. Según el Ministerio de Salud, los casos anuales de notificación de intoxicación aguda por plaguicidas sobrepasa los 2000 indivíduos, siendo un 80% causado por exposición laboral. Este número no considera los casos de intoxicación crónica, por lo que el problema puede ser aún más grave.
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 for half the continent. In the context of Africa’s climate, the insect is now likely to build permanent and significant populations in West, Central and Southern Africa, and spread to other regions when temperatures are favourable, posing a major threat to food security.
CABI and AGRA are hosting a side event on fall armyworm at the African Green Revolution Forum 2017 in Abidjan, Côte d’Ivoire. If you are not attending the conference, you can watch the livesteam below on September 7 at 14:00 (UTC). The video will also be available after the event.
[Update 14:20]: Due to poor internet connectivity, we are unable to run the livestream. A video will be made available on this page after the event.
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.
The spread of pests and pathogens that damage plant life could cost global agriculture $540 billion a year, according to a report published on Thursday.
The report, released by the Royal Botanic Gardens (RBG) at Kew in London, said that an increase in international trade and travel had left flora facing rising threats from invasive pests and pathogens, and called for greater biosecurity measures.
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.
