Abstract

Translucent fluorescent yellow flight traps were significantly more attractive to citrus blackfly, Aleurocanthus woglumi Ashby, than opaque yellow and clear traps. Significant correlations were obtained between trap catches of adult A. woglumi and foliar densities of adults and sedentary immature stages. The biological interpretation of such correlations and potential use of flight traps to monitor population trends of A. woglumi are discussed.

Résumé

Des pièges d’envol translucides jaunes fluorescents se sont avérés significativement plus attirants pour l’aleurode Aleurocanthus woglumi Ashby attaquant le citronnier, que des pièges jaunes opaques ou des pièges transparents. On a obtenu des corrélations significatives entre les captures des A. woglumi adultes et les densités foliaires d’adultes et d’immatures sédentaires. On discute de la signification biologique de ces corrélations et du potentiel d’utilisation des pièges d’envol pour la surveillance des fluctuations d’abondance de l’A. woglumi.
