Abstract

Morphometric analysis was studied on the measurements of the forewings, ovipositor, hind tibia, and antenna of female Anagrus giraulti Crawford reared from the following hosts: Circulifer tenellus Baker, Empoasca fabae (Harris), and Scaphytopius nitridus (DeLong). Results showed that A. giraulti emerging from E. fabae had significantly shorter antennal segments, ovipositor, and tibia III than those reared from the other two host species. Host eggs of C. tenellus produced female A. giraulti with significantly longer wing lengths than did the other two species and wider wing widths than did E. fabae.

Résumé

On a fait une analyse morphométrique des mesures d’ailes antérieures, d’oviscapte, de tibias postérieurs et d’antennes des femelles d’Anagrus giraulti Crawford, élevées sur les hôtes suivants : Circulifer tenellus Baker, Empoasca fabae (Harris) et Scaphytopius nitridus (DeLong). Les résultats montrent que des A. giraulti émergeant d’E. fabae ont les articles antennaires, l’oviscapte et les tibias III significativement plus courts que ceux élevés sur les deux autres hôtes. Les oeufs de l’hôte C. tenellus ont donné des femelles A. giraulti dont les ailes étaient significativement plus longues que les deux autres espèces, et plus larges que E. fabae.
