Abstract

Nerve cord sectioning in the early fifth instar larva of Papilio demoleus inhibited or delayed pupation depending on the site of sectioning. This seems to be due to interruption in the feeding leading to interruption in the proprioceptive input reaching the brain. Sectioning of the peripheral nerves N5 and N8 prevented shortening (condensation) of the thoracic segment of the ventral nerve cord in the adult. Sectioning of these and other nerves, however, had no effect on the developmental events.

Résumé

Le franchement du corde de nerf de le début du larvae des cinquième stade des Papilio demoleus empêchant ou attardant la pupation dépendent sur le lieu du coupure. Cela semble être à cause de l'interruption de la nourriture qui cause l'interruption due message proprioceptive entrant à la cervelle. Le tranchement des nerfs périphérales N5 et N8 empêchait la diminuation en longueur (la condensation) du segment thoracique du corde de nerf ventrale aux adultes. Le tranchement de ces nerfs et d'autres nerfs néanmoins n'avait pas d'effet sur les evênements dévélopmentaux.
