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.
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.
Calatayud Paul-André is a research scientist at IRD (Institut de Recherche pour le Développement). His research interests are the plant-insect relationships including the plant physiology (plant defense mechanisms, physiological changes due to abiotic and biotic constraints), the insect behaviour (host plant selection and feeding behaviour), the insect physiology (nutritional requirements and development) and the interactions of these relationships with the third trophic level, the parasitoids.
Le Rü Bruno is a research scientist at IRD (Institut de Recherche pour le Développement). His research interests are the plant-insect relationships including the pattern and evolution of host-plant use, the insect behaviour (host plant selection process), the community structure of phytophagous insects and their parasitoids and the exchanges between natural and cultivated habitats.
