Most basic information on plant-mealybug interactions during the last decade has come from research on the cassava Manihot esculenta Crantz (Euphorbiaceae) system with two mealybug species, namely Phenacoccus manihoti Matile-Ferrero and Phenacoccus herreni Cox and Williams (Sternorrhyncha: Pseudococcidae). Both these insects cause severe damage to cassava in Africa and South America, respectively. This book reviews these interactions (plant selection by the insects, nutritional requirements, influence of the climate, intrinsic and extrinsic plant-defence mechanisms). It should be useful for entomologists, crop scientists, agronomists and ecologists as well as for teachers and students. Au cours des dernières décennies, la plupart des recherches sur les interactions plantes-cochenilles farineuses ont porté sur le modèle manioc-cochenilles (Manihot esculenta Crantz, Euphorbiaceae/Phenacoccus manihoti Matile-Ferrero et Phenacoccus herreni Cox et Williams, Sternorrhyncha, Pseudococcidae). Ces insectes peuvent être respectivement responsables de pertes de récoltes importantes dans les parcelles de manioc en Afrique et en Amérique du Sud. Cet ouvrage présente ces interactions ainsi que les facteurs qui les influencent : mécanismes de sélection de la plante par les insectes, identification des éléments nutritifs de la plante pour le développement des insectes, mécanismes de défense intrinsèques et extrinsèques de la plante aux insectes et influence du climat sur ces interactions. Il s’adresse aux entomologistes, améliorateurs de plantes, agronomes et écologistes ainsi qu’aux enseignants et étudiants.
