Abstract

The occurrence and distribution of Cerataphis palmae (Ghesquierei) on Raphia palms in six Southern States of Nigeria, were studied. The percentage infestation of palms in the States were 24.9% (Bendel), 41.23% (Cross River), 37.17% (Imo), 34.73% (Lagos), 11.55% (Oyo) and 28.0% (Rivers). C. palmae is found in places in Southern Nigeria where Raphia palms, particularly R. hookeri Mann & Wendl. and R. vinifera Beauv. occur. There was no significant difference in percentage aphid coverage among the six States (F = 2.013; 0.01 < P > 0.05).

Résumé

L'occurence et la distribution de Cerataphis palmae (Ghesquierei) (Homoptera: Pemphigidae) sur les palmes de Raphia dans six états au sud du Nigéria ont été étudiées. Le pourcentage d'infestation des palmes dans les états était de 24,9%, (Bendel), 41,23% (Lagos), 11,55% (Oyo) et 28,0% (Rivers). C. palmae se trouve dans les endroits au sud du Nigéria où les palmes de Raphia, en particulier R. hookeri Mann & Wendl. et R. vinifera Beauv., se produisent. II n'y avait pas de difference importante dans le pourcentage de champ d'application aphid dans les six états (F = 2,013; 0,01 < P > 0,05).
