Pest management must consider the landscape context according to ATTIC project PhD thesis

by Carolyn Cowan

The control of crop pests has long been linked with chemical products like pesticides and insecticides. However, chemicals are often too expensive for smallholder farmers and require careful, appropriate use to ensure effectiveness. What if we could take advantage of natural ecological processes to suppress unwanted organisms, lessening our reliance on external inputs? This is the topic addressed in “Hide and seek: management and landscape factors affecting maize stemborers, Busseola fusca, infestation levels in Ethiopia,” the recent Ph.D. thesis by Yodit Kebede, completed at Wageningen University, Netherlands with support from the CGIAR Research Program on Maize (MAIZE) and the International Maize and Wheat Improvement Center (CIMMYT). The implications of the research hold significance for prominent pest control challenges like fall armyworm in Africa and beyond.

New maize hybrid shows resistance to stem borers in South Africa

Smallholder farmers in South Africa can now access and grow new maize varieties with transgenic resistance to stem borers, the most damaging insect pest of maize.

Partners in Water Efficient Maize for Africa (WEMA) – a public-private crop breeding initiative that helps farmers manage the risk of drought and stem borers infestation in Africa –developed the genetically modified maize seed branded as “TELA” that has been released and  licensed to seed companies in South Africa at royalty-free to sell to farmers at an affordable cost.

TELA derived from a Latin word Tutela meaning “protection”contains a gene from Bacillus thurigiensis (Bt) that helps the maize to resist damage from major stem borers to give farmers better yield. Five seed companies – Capstone, Jermat, Monsanto, SeedCo and Klein Karoo – are marketing the seed to smallholders.
