Let's preserve it
Biocontrol in Grande Comore
In July 2015, Nicolas Odaglia, Research Engineer at CIRAD, was responsible for assessing the impact of a biocontrol action done eight years before in Grande Comore to control whitefly populations affecting the island’s coconut trees. The conclusion of his survey, carried out in collaboration with an INRAPE team, confirms the opinion of Comorian specialists: the results are positive.
The American researchers Robert Dowell and Eric Jang both work in the US on fruit flies. They have toured the world onto Reunion Island to come and test a new method of biological control against Bactrocera zonata.
Honeybees of the Indian Ocean Islands: a diversity that must be preserved
Local honeybees are of major importance for both the economy and the environment. On the islands of the Southwest Indian Ocean, apiculture is an important activity, especially in Reunion Island, Madagascar, Mauritius and the Seychelles. The preservation of bees, which are essential for the pollination of plants, requires a better knowledge of their diversity.
The battle against fruit flies continues in the Comoros
The fruit fly Bactrocera invadens (or dorsalis) was detected in 2005 in the Comoros archipelago and poses a considerable threat to fruit crops there. To control this pest, a biological control program was launched in 2013. This program, part of the thesis of entomologist Issa Mze Hassani, will examine the behavior of species of fruit flies in order to prepare for the introduction of one of its natural enemies, the tiny wasp Fopius arisanus.
Active epidemiological surveillance of Bacterial wilt in the Indian Ocean
Ralstonia solanacearum is a bacterium responsible for the wilt of a large number of cultivated and wild plants worldwide. Some strains of this bacterium are recognized as a quarantine pest in Europe and potential bioterrorism agent in the US. R. solanacearum can cause the loss of an entire crop and usually leads to the death of the plant.
