Abstract

Correlations were established between an endemic infestation of the coffee margorodid, Icerya pattersoni Newst and the characteristics of the veins of the leaves it infested in four coffee species in Kenya. The attack was variable between species although there was an affinity for it to be confined to midribs of definite length and thickness and laminal veins of quantifiable dimensions.

Résumé

Les corrélations ont été établies entre les infestations endémiques de Icerya pattersoni sur le cafeier et les charactéristiques des veines des foliares de quatres espèces de cafeier au Kenya. L'attaque a ètè variable entre les espèces bien qu'il y a eu une affinité en se limitant à la veine principale de longueur et d'épaisseur determinées. Les veines secondaires ont été affectés sur des dimensions quantifiables.
