    Describe your research

    I work on various biological control options against fall armyworm in Africa and Asia: Classical biological control through importation of American parasitoids; augmentative biocontrol through the use of egg and larval parasitoids; conservation of naturally occurring natural enemies. I also supervise CABI efforts on the development of other control options such as cultural methods, biopesticides, etc.

    • Very easy. First, try to keep the insects alive during transport. When you find FAW egg masses, put them in individual vials and avoid direct sun or heat during transport. In the lab, the unparasitized larvae will hatch first. Keep the egg masses that have not fully hatched a bit longer and you will obtain adults of egg parasitoids (if you are lucky). For a small lab rearing, adults can simply be put in a vial with a fresh FAW egg mass obtained in the lab. If you want a mass production (e.g. for field releases), you have to use moth eggs that can be easily mass produced, such as those of Sitotroga, Ephestia or Corcyra. All protocols can be found in these manuals (and others): http://oar.icrisat.org/11322/ https://www.cabi.org/bookshop/book/9781789242027/

    • Thanks Simone. Indeed, in the Americas, there are many cases of non-cereals severely attacked. I just found less examples in Africa.

    • Parasitism by Telenomus remus seems to vary greatly in Africa. While some studies failed to find egg parasitoids, in Kenya and Tanzania, Sisay et al. (2019) mention 63% and 58% parasitism by T. remus, respectively. Agboyi et al (2019) measured 26% at one location in Ghana and 14% at another location in Benin. However, I suspect that parasitism rates in Kenya, Tanzania and Ghana were largely overestimated because egg masses parasitized by T. remus remain at least 4 times longer in the field than unparasitized egg masses. Furthermore, parasitized eggs are darker, and thus more visible during surveys. Data from in Benin may be more reliable because they result from very regular observations of the same plants. But this was just one site.
