Abstract

Detailed cytological survey of the developmental stages of Zonocerus variegatus L. revealed major aberrations like lagging, precocious activity of chromosomes, X-autosome associations, pseudochiasmata, deletions, etc. Chiasmata were found to be largely terminally localized and meiosis commences as early as the third instar stage. Models for autocidal control are proposed based on these findings.

Résumé

Un examen cytologique détaillé des étapes du développement de Zonocerus variegatus L. révéla des aberrations majeures comme une activité retardée et précocieuse des chromosomes, associations des X-autosomes, pseudochiasmata et deletions, etc. Chiasmata ont été trouvés d'être principalement et terminablement localisés, et meiosis commence aussitot que la troisième étape d'instar. Des modeles pour le controle autocidal sont proposés, bases sur ces découvertes.
