Abstract

Female Colorado potato beetles fed foliage of Solarium tuberosum of the Russet Burbank variety infected with potato leafroll virus have lower fecundity and shorter longevity than those fed virus-free foliage. Also, female beetles prefer feeding on foliage infected with potato leafroll virus. This observation could be of importance in the development of resistant varieties of potatoes to potato beetles.

Résumé

Les femelles du doryphore de la pomme de terre nourries du feuillage de Solarium tuberosum de la variété Russet Burbank infecté par le virus de l'enroulement des feuilles ont une fécondité et une longévité inférieures à celles qui sont nourries de feuillage libre de virus. Aussi, les femelles du doryphore préfèrent s'alimenter sur le feuillage infecté par le virus de l'enroulement. Cette observation pourrait être importante dans le développement de variétés résistantes aux doryphores.
