Autre titre : Variation de la population saisonnière chez deux vecteurs soupconnés de la maladie Wilt du Cap St. Paul chez le cocotier au Ghana, en rapport avec l'incidence de la maladie

Résumé : Results of a study of population trends in two putative vectors of Cape St. Paul Wilt Disease of coconuts (#Myndus adiopodoumeensis# and #Nzinga palmivora#) are presented. There were three peaks of #M. adiopodoumeensis# abundance and only two peaks in #N. palmivora#. There were three peaks of disease initiation in all cases studied at approximately the same period that #M. adiopodoumeensis# was at peak abundance. Regression analysis revealed a substantial relationship (r = 0.6) between #M. adiopodoumeensis# abundance and Cape St. Paul Wilt Disease incidence.
