Insects are the best example of biodiversity.
They represent the third of the living species and scientists discover new specie every day.
One group in particular has survived through many geological events : the insects.
While climate was changing regularly, they were able to adjust and develop.
Today, it is the human’s impact that is presenting a threat to insects.
With Philippe Le Gall, entomologist from IRD, we try to understand how, in this area of Cameroun mountains, the living is always in motion...
The coleoptera group accounts for about 350,000 species which is about a fourth of the total known species of one million.
Using the insects and their major biodiversity, availability and size, scientists have now a fundamental model that they can use for their research.
Cereals are one of the main staples of humans in sub-Saharan Africa. This is particularly true in Kenya where maize occupies the first place.
It is consumed in different ways : grilled, boiled as porridge, and ugali, which is favored national dish.
In Kenya, maize is mainly grown by small-scale peasant farmers.
Unfortunately, like other cultivated crops, maize is attacked by a plethora of diseases and insect pests, among the cereal stemborers.
The research presented in the three videos here below was implemented from 1998 to 2003 by the Mountain Agrarian Systems (SAM) Program, a joint research project of the Vietnam Agricultural Science Institute (VASI), the Institut de Recherche pour le Développement (IRD), the Centre de Coopération Internationale en Recherche Agronomique pour le Développement (CIRAD), and the International Rice Research Institute (IRRI).
