Abstract

Scanning electron microscope (SEM) micrographs of aedeagi and pygofer processes of some Cicadulina spp. are presented for the first time. They should assist in the identification of Cicadulina spp. by entomologists who are not trained in taxonomy, and who work in national research programmes in Africa without access to well-equipped libraries and reprint collections, that offer ready access to the original descriptions of Cicadulina spp. A number of national maize research programmes recently initiated studies on Cicadulina leafhopper biology, behaviour, ecology and mass rearing for resistance screening to streak virus and all of them face the problem of species identification. This report summarizes widely scattered publications and provides new illustrative information to assist in the identification of Cicadulina spp. by national scientists in Africa.

Résumé

Des microphotographies au microscope électronique à balayage des aedéages et du pygofère de quelques espèces de Cicadulina sont présentées pour la première fois. Elles devraient permettre l'identification des espèces de Cicadulina, par des entomologistes non spécialisés en taxonomie, travaillant dans des programmes nationaux de recherches en Afrique et n'ayant pas accès aux bibliotheques bien équipées et aux collections de tirés à part pour retrouver les descriptions originales des espèces de Cicadulina. Un certain nombre de programmes nationaux de recherches sur le maïs ont récemment initié de études sur la biologie, le compartement, l'écologie et l'élevage de masse des cicadelies du genie Cicadulina afin de cribler des variétés pour la résistance au virus de la stiure du maïs, mais sont tous confrontés au problème d'identification des espèces.

Le présent rapport est une compilation de publications largement répandues donnant des informations illustrées pour aider à l'identification des espèces de Cicadulina par les chercheurs nationaux en Afrique.
