FEMALE MEIOSIS IN EARIAS VITTELLA (FABR.) (NOCTUIDAE : LEPIDOPTERA) MAY BE ACHIASMATIC !

Abstracts

The behaviour of chromosomes during meiosis was studied in females of Earias vitiella (fabr.) (Noctuidae, Lepidoptera) The haploid chromosome number is 31. All bivalents are homomorphic and sex chromosomes can not be identified. Throughout prophase, frou pachytene until pro-metaphase all the bivalents remain associated non-homologously via telomeres, forming a single multibranched chain.
