Tomato farmers in Kenya believe area-wide pest management can easily be instituted and effectively control Tuta absoluta
Tomato is one of the most important vegetables grown in Kenya and plays a critical role in income generation and creation of employment for both rural and urban populations, in addition to meeting food nutritional requirements. Tuta absoluta – also known as tomato leafminer – is a native of South America (Peru) and is one…
Using online workshops to ensure the fight against invasive species continues in Pakistan
As the global COVID-19 pandemic continues, CABI is ensuring that efforts to combat invasive species are continuing. The CABI centre in Pakistan organized a one-day online workshop on the development of Pest Management Decision Guides (PMDGs) and Technical Briefs on the invasive pests: fall armyworm, parthenium weed, and Tuta absoluta.
Tomato farmers in Kenya willing to use integrated pest management and bioproducts to manage Tuta absoluta
Tomato is an important crop in meeting domestic nutritional food requirements as well as in income generation and creation of employment for both rural and urban populations in Kenya. However, tomato production is facing serious challenges from the invasive pest, Tomato leafminer (Tuta absoluta.) Since 2014, T.absoluta has become the most serious threat to the sustainable production…
Shedding light on the biodiversity impacts of the tomato leafminer
The ecological effects of a widespread crop pest The tomato leafminer Tuta absoluta is one of the most widespread and impactful invasive crop pests in the world. First reported in Peru in 1914, the tomato leafminer is now recorded throughout South America, Africa and Europe and is estimated to infest 60% of all cultivated tomatoes worldwide. Recent studies…
Collaborative writeshop produces pest management decision guides for invasive species in Pakistan
Invasive alien species (IAS) have devastating impacts on native biota, causing the decline or even extinction of native species, negatively affecting ecosystems. Invasive plants, animals, insects and microorganisms enter and establish in environments outside of their natural habitat. They reproduce rapidly, out-compete native species for food, water and space, and are one of the main…
Two heads may be better than one: using multiple methods in the fight against Tuta absoluta
Tuta absoluta is a major invasive pest that causes devastating crop damage worldwide. Insecticides are heavily relied upon to help curb their numbers, but because of problems with increased insecticide resistance and the environmental impacts of insecticides, scientists are trying to find new ways of fighting this pest.
CABI announces major commitments in fight against invasive species
Coinciding with its regional consultation with member states in Africa, CABI hosted a policy summit on invasive species in Gaborone, Botswana on 28 February. About 70 delegates representing policymakers, research, the private sector and civil society from across Africa gathered to learn about and discuss the impact of invasives as well as the technical and…
CABI scientist helps provide a comprehensive review of research on Tuta absoluta in Africa
The South American tomato leafminer, Tuta absoluta, is a devastating invasive pest of tomato crops in several areas around the world, including Africa where the problem is greatest. Given the wealth of research conducted on T. absoluta, a recent publication involving one of CABI’s scientists, Dr Marc Kenis, has compiled a comprehensive review of the…
New Fall Armyworm Portal features as part of CABI’s upgraded Invasive Species Compendium
A new Fall Armyworm Portal, which includes the very latest reports and research regarding the devastating crop pest, now features as part of a major upgrade of CABI’s Invasive Species Compendium (ISC) launched today. The portal, created as part of the CABI-led Action on Invasives programme – funded by the UK’s Department for International Development (DFID) and the Netherland’s Directorate-General…
Using roundworms to manage the Tomato Leaf Miner
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…
