Abstract
This study investigated the segmental distribution of various types of antennal sensilla in the post-embryonic developmental stages of the brown-banded cockroach, Supella longipalpa Fabricius. Three major types of mechanosensilla and chemosensilla were identified. A progressive increase in the number of various types of sensilla with increase in the number of segments as well as nymphal stages and adults was observed. The density of sensilla chaetica and sensilla basiconica increased approximately 12.5- and 24-fold from first nymphal stage to males respectively, while density of sensilla trichoidea increased 8-fold from 2nd nymphal instar to adult stage. A high degree of correlation between the average total number of sensilla and post-embryonic stages was observed.
Résumé
La distribution des segments des types variés de sensilles antennaires au cours des stades de développement post-embryonnaire de Supella longipalpa Fabricius a été étudiée. Trois grands types de mechanosensilles et chemosensilles ont été identifiées. On a observé un accroissement progressif des divers types de sensilles avec l’accroissement du nombre des segments ainsi qu’avec les stades nymphaux et adulte. La densité des sensilles chaetica et des sensilles basiconica s’est accrue d’env. 12,5 et 24 fois du 1er instar nymphal jusqu’à l’adulte respectivement, tandis que la densité des sensilles trichoïdes s’est accrue de 8 fois du 2ème instar nymphal au stade adulte. Un fort degré de correlation a été observé entre le nombre total moyen de sensilles et les stades post-embryonnaires. Ceci semble être la mention pour la 1ére fois de la distribution des segments des sensilles antennaires chez les stades de développement post-embryonnaire du cancrelat Supella longipalpa.
