Myth or reality ? The "Hopkins principle" in the case of the groundnut seed beetle, Caryedon serratos (Coleoptera, Bruchidae). Our purpose is to study the bases of oviposition site selection by females of various groundnut seed-beetle strains, Caryedon serratus, bred from different hosts. Egg distributions among hosts are compared. The results indicate that strains may be considered as developing according to Hopkins' host selection principle because females lay preferentially their eggs on the host they were bred from. The behaviour of females artificially bred on corn seeds shows however that host selection is not under the sole influence of the nature of larval food.Nous étudions le déterminisme du choix du substrat de ponte par des souc...
