Abstract

The activity of glutamate-pyruvate transaminase (GPT) increases regularly as the fourth instar larva of Zabrotes subfasciatus develops into prepupa. On the other hand, glutamate-oxaloacetate transaminase (GOT) activity increases significantly (P < 0.05) during the first 12 hr, and then remains at a sufficiently constant level during the subsequent development of this larval instar except at 36 hr of development. However, at the time of prepupation, the GOT and GPT-activities show a decline, which is subsequently followed by an increase during the rest of the prepupal development. The activity of GOT is quite high during the early pupal life, i.e. up to 120 hr. On the other hand, GPT-activity falls significantly (P < 0.05) during the first 24 hr of pupal life and rise up to 120 hr during pupal development. Once again, in the late pupal development, the transaminases remain very active on account of the faster rate of histogenesis. During early adult life, the GOT and GPT are still active, as the early part of adult life of the insect is physiologically quite vigorous and accordingly the energy requirements of the body at this stage are intense. Subsequently, there occurs a regular attenuation of the activities of both of the transaminases in the aging bruchid.

Résumé

L'activité des glutamate-pyruvate transaminase (GPT) augment régulièrement à measure que la quatrième instar larva de Zabrotes subfasciatus développe en prépupa. Au contraire, l'activité du glutamate-oxaloacetate transaminase (GOT) augmente significativement pendant les premieres 12 hr et ensuite reste a un inveau suffisament constant pendant le dévelopment du instar larva qui suive, sauf à la 36e hr du dévelopment. Pourtant au moment de la prépupation, les activités des GOT et GPT montrent une dimunition qui est ensuite suívi d'une augmentation pendant le reste due dévelopment prépupa. L'activité de GOT est assez élevé pendant le début de l'âge pupal, l'est à dire jusqu'à la 120e hr. Au contraire, l'activité GPT décrôit significativement (P < 0.05) pendant les premiéres 24 hr de la vie pupale qui pourtant continue à augmente jusqu'a la 120e hr du développment pupale. Encore, pendant le développement pupal tardif les transaminases restent très actifs à cause ce cadence plus rapide de histogenesis. Pendant le commencement de l'àge adulte, le GOT et le GPT sont encore actifs, puis que la première partie de la vie adulte de l'insecte est assez vigoureuse et en conséquence les besoins de l'energie du corps en ce moment sont intenses. Ensuite, il se produit une atténuation régulière des activités des deux transaminases dans les bruchids vieillissants.
