Citrus Greening, also known as Huanglongbing, was first confirmed in Grenada in 2016. The disease is caused by bacteria which are spread by the Citrus psyllid. The disease causes yellow blotchy mottling on leaves, small lopsided fruit and branch dieback, making the tree uneconomical. Due to Citrus greening’s potential to devastate Citrus yields, Grenada’s Ministry of Agriculture has launched a campaign to control the disease, which has been detected in almost every area of the island. In the video above, Thaddeus Peters, Agricultural Officer for the MoA’s Pest Management Unit, explains the importance and methods of controlling Citrus Greening. Continue reading
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
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 estimate that, if not properly managed, the pest will cost 10 of Africa’s major maize producing economies a total of $2.2bn to $5.5bn a year in lost maize harvests.
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.
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 show the life cycle of the Fall armyworm, which includes egg, 6 growth stages of caterpillar development (instars), pupa and adult moth.

Huanglongbing (HLB), also known as Citrus greening, has been confirmed in Trinidad for the first time. The disease, which was detected on leaves from a lime tree in the north of the island, can cause devastating yield loss for Citrus growers and is regarded as one of the most important threats to global commercial and sustainable citrus production.

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.
