Using roundworms to manage the Tomato Leaf Miner

The tomato leaf miner, Tuta absoluta

Research recently published in the Journal of Economic Entomology has offered new insight into managing the tomato leaf miner (Tuta absoluta) using entomopathogenic nematodes (EPN). If the pest is not adequately managed, it can cause up to 100% crop loss in both field and green-house grown tomatoes. Also causing further concern is the increasing insecticide resistance the pest has shown to be developing.

Taking on Fall Armyworm in Africa: The search for effective natural enemies

The Fall Armyworm (FAW), Spodoptera frugiperda has emerged as a serious threat to food security for millions of smallholder producers in Africa due to its rapid spread across the continent and extensive damage to staple cereals. At the last count, at least 28 countries were reported to be affected by the pest in Africa.

The fall armyworm is still invading regions in Africa. Since 2016 this worm has been spreading across sub-Saharan Africa and has been officially identified in 11 countries. Roger Day from the Centre for Agriculture and Biosciences International (CABI) elaborates on its dangers in this blog and provides recommendations for governments and farmers.

A facility has been launched in Kenya to aid commercial production of a protein bait to control fruit flies in Sub-Saharan Africa. The US$250,000 facility, which resulted from public-private partnership involving the International Centre of Insect Physiology and Ecology (icipe) and Kenya Biologics Ltd, will enable smallholders control fruit flies that devastate their fruits and vegetables.

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.

Where to find CABI’s open-access information on fall armyworm

cabi_invasives_faw

The fall armyworm, Spodoptera frugiperda, is making headlines worldwide for all the wrong reasons. The caterpillar crop pest, native to the Americas, was reported in Africa for the first time last year and is now rapidly marching across the continent. It is a voracious pest of maize and other staple crops and has already destroyed tens of thousands of hectares of farmland. As such, it risks devastating smallholder livelihoods throughout Africa. Given that CABI scientists predict it could reach Europe and Asia in a matter of years, it looks set to quickly become a global problem.

The case for action against fall armyworm is overwhelming. On the ground, CABI will support national extension services to help farmers identify the pest quickly and accurately, contribute to awareness-raising and conduct studies to work out the best ways to control it that are not overly dependent on insecticides. Alongside these efforts, CABI also has a range of freely-available materials to help people understand and manage fall armyworm. Continue reading
