    Describe your research

    Fall armyworm biological control. Fall armyworm localy present parasitoids and predators scouting and I dentification in the West Africa sub region. Parasitoids and predator rearing in laboratory for release in maize fields. Evidence of feeding reduction in fall armyworm after being parasitize by Coccygidium luteum. Currently working on fall armyworm Area-wide Management in Ghana under the CABI Action on Invasives program. Interaction between two larval parasitoids in the presence of their host, Fall armyworm. Testing the efficacy of T. remus on Fall armyworm with the CABI Action on Invasives team.

    • Spodoptera frugiperda and other Spodoptera species suspected to be S. littoralis have been observed in maize farms in Ghana. What is the implication of the coexistence and infestation of these Spodoptera species to FAW management and crop protection. How does this affect Natural enemies population dynamics and effectiveness?

    • This is very interesting.

    • This is interesting and I will love to test this app. Currently at the Plant Protection And Regulatory Services Directorate, Ghana lab. Have FAW and other non FAW larvae. samuelmensah1a@gmail.com

    • Thank you. Grateful to have the chance to learn.

    • Thank you Geoffrey. The first was scouted and collected in Two ecological zones in Ghana (2018) and the lather in the Bono region, which is the food basket of Ghana in November 2020.

    • Hi Dike, will be a great pleasure to collaborate on SDG4 for ESD projects.

    • @agnamto Agnamba, @Kwadwo Gyasi, @Isaac Badu, @Babatoundé Ferdinand Rodolphe LAYODE, @Itohan. I will be much grateful if you can send questions to earlier discussions on FAW Parasitoids and predators so it will be addressed at the webinar. Kindly use the link posted by @clairecurry to register for the webinar.

    • FAW Predator rearing requires many FAW larvae for feeding. What are other measures used for rearing FAW for predator feeding and are there supplementary diets for predator feeding?

    • Great submissions, Sundar and Aislinn. To add to the above stated.., a larger number of farmers are the resource poor and sometimes haven't acquired formal education. This creates a gab between channeling of information and absorption for implementation. There is the need that we critically observe these grabs and know how to channel information to a particular audience, in this case farmers. In some cases, farmers are not made to own or better said, feel like a part of an ongoing effort to manage the FAW pest problem. Paticipatory approach targeted at a specific audience or group might be very helpful in getting farmers to understand and support the long-term control through active Farmer Field Schools.

    • Before #Fall armyworm invaded Ghana in 2016, African armyworm was one of the major pest of maize in the African sub region. as it stands, no African armyworm (Spodoptera exempta) have been found during FAW sampling since 2017 till date(2020) by the #CABI action on invasive team. There was a report on a worm infestation on the Cape coast stadium lawn which was suspected to be a likely African armyworm attack in 2017.
