Abstract

Fertilized eggs of non-destructive termite species, Ilospitalitermes luzonensis Oshima were collected, fixed with Farmer's solution and stained with lacto-aceto-orcein. Distinct features of the four stages of mitosis, namely: Prophase, Metaphase, Anaphase and Telophase, were observed and described. Nuclear shape and dimensional differences were observed at the Prophase stage wherein the nuclei were generally oval. Mean mitotic index was 49% and the most frequently encountered stage was Prophase while Anaphase being the least. Karyotypc analysis using Prometaphase chromosomes showed that the chromosome number of H. luzonensis was 2n = 42 (40A + xx y/ XYd) and the mean relative lengths of chromosomes ranged from 0.0305 to 0.0810.
