Submit questions on: the collection and identification of FAW parasitoids and predators

Please post questions in the comments below to be answered in the upcoming ASEAN technical workshop on the “collection or identification of FAW parasitoids and predators in the field” 

Questions will be passed to the organisers to be answered by Dr Marc Kenis during the workshop on the 17th Dec. Register for the workshop here – https://zoom.us/webinar/register/WN_kY8-xKiKTmqBxkVMewWenQ

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.

The augmentative releases of T. remus and T. chilonis can effectively control FAW damage in Africa.  After the collection and identification of parasitoids in West Africa (Parasitoid complex of FAW Ghana and Benin), a follow up research is ongoing in Ghana on the effectiveness of T. remus in FAW control by the CABI Action on invasive team in collaboration with Plant Protection and Regulatory Service Directorate, Ghana.  T. remus will prove a good and effective bio control candidate because it generally averages between 30 to 50% FAW egg parasitism (Liao et. al, 2019) and can reduces the emergence of FAW… Read more »

One of the major challenges in FAW related research is the problem of cannibalism amongst the FAW larvae after the second instar (4 days old). How can this be minimized or prevented.

How can FAW parasitoids survey and identification be done to reflect the true parasitoid diversity and population estimates of a given geographical area, as different parasitoid species have specific or a range of FAW larval instar preference?

What are the common tools for the collection of FAW predators and parasitoids? How we can preserve them for a long time. What are the key identification features (Morphological and Taxonomic Key) of potential predators and parasitoids?

The enhancement of multiple natural control processes is the key factor in the long term management of FAW – than goodness for CABI. This is easy to say but less easy to achieve – we are talking about a global problem. Generic issues, yes, but my experience as published is transferable across political borders and species. Positive actions = ensuring that natural enemies such as ladybirds and insectivorous birds are retained in the farm environment during the cropping season and the dry season – bird perches… refuges (an off season home for the preds and pars) = allow weeds to… Read more »
