        <dc:description>The egg parasitoid Gryon fulviventre is a potential biological control agent of Clavigralla tomentosicollis, a coreid pod-sucking&#13;
pest of Vigna unguiculata. The host location behavior of naive parasitoid females was studied using a four-armed olfactometer. Two strains of G.&#13;
fulviventre parasitoids from Burkina Faso and Benin were exposed to odors provided by healthy and infested pods as well as C. tomentosicollis&#13;
females and males. The time spent in each odor zone was recorded to determine the preference of parasitoid females. Results show that odors&#13;
from healthy pods, infested pods, and pest females did not attract the parasitoid. However, a significantly attractive response of both strains of&#13;
G. fulviventre was recorded in the presence of volatiles from males of C. tomentosicollis. Moreover, experiments testing G. fulviventre females’&#13;
behavior when simultaneously exposed to volatiles from cowpea pods (healthy and infested) and increasing numbers of C. tomentosicollis&#13;
males revealed a significantly higher attraction of parasitoid females of both strains by volatiles from ten males of C. tomentosicollis. The results&#13;
suggest that the males of the insect pest emit a pheromone used as kairomone by parasitoids to locate their host. The conditions determining&#13;
this attractiveness at field level and its impact on host-searching efficiency are discussed.</dc:description>
