Abstract:
The increase in vegetable production in northern Cote d Ivoire is severely limited by insect pests,
particularly aphids, whose action is poorly studied. An inventory of aphids was carried out at 600
producers of zucchini, cucumber, cabbage, eggplant and sorrel distributed in the market
gardening areas of Korhogo, Sinematiali and Ferkessedougou by sampling attacked leaves.
Similarly, pest control methods and cultural practices have been identified. Analyses showed that
vegetable crops in this area were infested by Aphis. gossypii, Aphis. fabae and Aphis. nasturtii.
Of these three species, A. gossypii was the most common. The most infested crops were
cucumber with 347.22 12.69 aphids and cabbage (326.78 10.56). To control aphids, growers
use insecticides, the majority of which are not indicated. In addition, monoculture plants
recorded more aphids (749.78 27.82) than those in crop associations (706.44 11.26). |
