Can intercropping make fall armyworm’s natural enemies more effective?
Native to tropical and sub-tropical America, the highly invasive fall armyworm (FAW), Spodoptera frugiperda was first reported in Africa in 2016. The pest quickly spread to every country in sub-Saharan Africa, reaching Zambia in late 2016. Fall armyworm larvae feed on over 80 different host plants, including maize – a key subsistence crop for millions…
Could Telenomus remus go global?
The parasitoid wasp Telenomus remus has been mass released as a biological control agent against fall armyworm (Spodoptera frugiperda) in the Americas (where the pest is native) for a number of years. However, fall armyworm is now highly invasive, found across Africa, Asia, and Australia. Can the lessons learnt from its wide use in the…
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…
Could invasive plant management prevent the spread of malaria?
CABI scientists have joined an international team of experts who suggest that the large-scale management of a range of some invasive plants could hold the key to reducing the spread of deadly malaria. Dr Arne Witt and Dr Sean Murphy worked with scientists from the University of Illinois, The Ohio State University and the Fundación…
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…
Kenya gets new production facility to control crop pest
By Sam Otieno. Reblogged from SciDevNet 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…
