Abstract: 

In Côte d'Ivoire, parasite pressure is the major constraint to millet production. The entomofauna of this plant was evaluated on a plot of millet of 252 m 2 (20 m x 12.6 m). Once a week, from sowing to heading, three types of harvest were made. There are: the first from the filleting net, the second by direct observation and harvest by hand and the third with the help of colored plates. This inventory has permitted to collect 3671 individuals belonging to 9 insect orders. These 9 orders were Coleoptera, Diptera, Hemiptera, Hymenoptera, Lepidoptera, Orthoptera, Isoptera, Dictyoptera and Dermaptera. These orders were composed of 62 families. Taking into account the phases, the analyses showed that the main groups subservient to millet during the vegetative phase were Hemiptera, Hymenoptera, Diptera, Lepidoptera and Coleoptera. During the heading phase the entomofauna was marked by the presence of Hymenoptera, Lepidoptera and Hemiptera.
