Abstract

The multiporous plate sensillum occurs on the antennae of Hymenoptera. The internal and external cuticular surfaces of these sensilla, as well as the cellular ultrastructure, were examined in the Braconidae by electron microscopy. The sensillum has an elongated, external, porous plate and an inner, cuticular septum in which there is an aperture. It is innervated by numerous neurons, the dendrites of which pass through the aperture, branch and traverse the longitudinal axis of the sensillum. The ratio of aperture length to sensillar length was measured on the internal cuticular surface in 32 species. This ratio increased from the ancestral to the derived species. This sensillar character may be useful in elucidating braconid systematics. It also has potential use in the systematics of other hymenopterous parasitoids.

Résumé

Le sensille de type plaque multiporeuse se retrouve sur les antennes des Hyménoptères. Les surfaces cuticulaires interne et externe de ces sensilles, de même que leur ultrastructure cellulaire ont été examinées chez les Braconidae par la microscopie électronique. Le sensille a une plaque poreuse externe allongée, et un septum cuticulaire interne muni d’une ouverture. Il est innervé par plusieurs neurones dont les dendrites passent par l’ouverture, se divisent et traversent l’axe longitudinal du sensille. Le rapport longueur de l’ouverture sur la longueur du sensille a été mesuré sur la surface cuticulaire interne chez 32 espèces. Ce rapport augmente en passant des espèces ancestrales aux espèces dérivées. Ce caractère sensillaire pourrait être utile pour clarifier la systématique des braconides. Il pourrait également s’avérer utile à la systématique d’autres parasitoides hyménoptères.
