    Describe your research

    Direct estimation of maize yield loss caused by fall armyworm using six CIMMYT genotypes in artificial and on natural infestation in major maize growing agro ecologies in Kenya. In addition, i conducted a trial on the life table of the fall armyworm in controlled conditions using the same genotypes as natural diet for the larvae as well as for the fecundity studies.

    • Hello Steve Thank for this question. Well a range of studies have estimated yield loss caused by FAW in Africa. Kumela et al. (2018) reported a yield loss of 47% in Kenya based on farmers perceptions. A recent study in Kenya reported 34% yield loss caused by FAW in the long rains of 2017 and 32% in both the short rains of 2017 and long rains of 2018 using community surveys (De Groote et al., 2020). Actual experimental yield loss are usually very infrequent due to pest occurrences and also establishing good control plots as you mentioned. However, CIMMYT-Kenya is currently working on the first Country-wide yield loss assessment caused by FAW. This results are expected to be out by the end of the year.

    • Thank you @sharanu-deshmukhgmail-com for this. When conducting this study its also important to check the activity of natural enemies.

    • Can augmentative releases of T. remus and T. chilonis in Africa effectively control the damage caused by FAW as compared to the full control ? In latin Latin America T. remus in maize fields showed 90% parasitism.

    • Very useful information @sharanu-deshmukhgmail-com .Thank you for sharing this.

    • The assessment of yield loss associated to FAW is crucial for sustainable management option in Nepal. Extension of knowledge on the identification of this pest is Key. Thank you for sharing this @ruchita-bhattarai .

    • Hello Pearson To my knowledge this is the first time, monitoring network comprising of radar, pheromone traps, machine learning and decision support apps have been established in SSA. This is impressive work, it provides a baseline for adoption and a more realistic development of digital monitoring in SSA.
