Abstract

Male and female adult wasps belonging to the atomus group of the genus Anagrus Haliday, classified according to morphological techniques, were analyzed for their cuticular hydrocarbons to detect any possible differences between species. Most female specimens that were identified as either A. atomus L. or A. ustulatus Haliday, using morphological and morphometrical characters, showed two distinct cuticular hydrocarbon profiles. These profiles seemed to be independent of the plants the insects were collected from, the potential leafhopper host species (Hemiptera: Cicadellidae), and the emergence period, and they were largely consistent with classification based on morphology. Both A. atomus and A. ustulatus females were shown to emerge from leafhopper eggs found on Vitis vinifera L. (Vitaceae). Males, for which conclusive diagnostic characters are not yet available, showed the same two cuticular hydrocarbon patterns observed in females; on average, specimens displaying one hydrocarbon profile differed from those showing the other profile in three characters used for morphometrical analysis.

Résumé

Nous avons analysé les hydrocarbures de la cuticule chez des adultes mâles et femelles de guêpes Anagrus Haliday classées au moyen de techniques morphologiques dans le groupe atomus, afin de déceler les différences spécifiques possibles. On trouve deux patrons distincts d'hydrocarbures cuticulaires chez la plupart des spécimens femelles identifiées comme A. atomus L. ou A. ustulatus Haliday à partir de critères morphologiques et morphométriques. Ces patrons semblent indépendants des plantes sur lesquelles les insectes ont été récoltés, de l'espèce de cicadelle (Hemiptera : Cicadellidae) qui sert d'hôte potentiel et de la période d'émergence; ils correspondent en grande mesure à la classification basée sur la morphologie. Les femelles d'A. atomus et d'A. ustulatus émergent toutes les deux des oeufs de cicadelles vivant sur Vitis vinifera L. (Vitaceae). Les mâles, pour lesquels il n'existe pas encore de caractères diagnostiques décisifs, possèdent les deux mêmes patrons d'hydrocarbures cuticulaires que les femelles; en moyenne, les spécimens ayant l'un des profils d'hydrocarbures diffèrent de ceux qui ont l'autre profil par trois caractères utilisés dans l'analyse morphométrique.
