IITA in Africa


IITA-Benin key facilities: what we offer

• A biodiversity centre: the largest and best curated collection of insects in West Africa, the foundation for biological control and IPM at large



• A bio-pesticide production unit

• Insectaries: mass production of arthropod biological control agents



• An IPM outreach unit: engages in capacity building, participatory technology testing, technology dissemination and impact assessment

• An agro-(socio)-economics unit: with particular focus on value chain analysis, ex-ante and ex-post impact studies for IPM projects, and capacity building



• An agro-eco-health platform: with particular focus on linkages between agriculture and human health

• What are the likely benefits for IITA (Benin) working with UIUC

• What are the synergies

• What are the win-win situations


IPM-omics


The legume pod borer, Maruca vitrata


Population ‘migration’ of M. vitrata based on available data from light traps and host plant surveys: implication for control strategies

Another important application of IPM-omics:

origin of M. vitrata


What’s the origin of M. vitrata and why do we bother?

M. vitrata M. amboinalis

Population genetic studies are an indispensable tool in modern bio-systematics


On-going collaborative project with AVRDC and icipe:

Exploiting the large diversity of M. vitratanatural enemies in Asia

A. taragamae and MaviMNPV flying together !

+ = !!!!!

Happening right now…

Exotic parasitoid from Asia: Apanteles taragamae Entomopathogenic

Baculovirus MaviMNPv


Model for technology deployment using caged field nurseries

using Sesbania cannabina plots: up to 40 cocoons/sqm; using Tephrosia platycarpa plots: up to 26 cocoons/sqm


Biocontrol and biopesticides in the pipeline……but need IPM-omics (htp sequencing and bioinformatics) to accelerate deployment strategy

Summary of findings

1) SNP and microsatellite tools developed

2) Populations genetic studies support the hypothesis of S-N host-switch migration during rainy season

3) LPB constitutes minimally two different species (based on mitochondrial data)

Recommendations for Biocontrol

1) Endemic zone extends into southern Burkina Faso

2) Biocontrol agents can be released into these areas this far north

3) Aqueous formulations of neemoil and virus (MaviMNPV) spray just as effective as pesticides and in some cases better, needs multi-location validation


Search for innovative solutions…

Rearing methodology with germinating cowpea grains is 25-30x less expensive than standard artificial diet for the same larval output level !!!


…opens up new opportunities for collaboration:

‘cottage industry’ production of beneficial organisms by women groups and/or unemployed youth, creating a steady supply of biological control products and additional household income


Educational materials


Capacity building and technology dissemination…

Outlook:Strengthening the collaboration with UIUC

Other insects/organisms of agricultural importance (cowpea, but also other crops)

Education materials for ‘cottage industry’ production of beneficial organisms and their deployment in the field

Education materials for agro-eco-health interventions (Buruli ulcer)


Thank you for your

attention !
