Abstract
This study was conducted to provide basic information on the cytogenetics of the commercially-used large tree nymph butterfly or paper kite, Idea leuconoe Erichson. To look at the chromosomes of this nymphalid, eggs were acquired from a private butterfly rearing station situated in Bay, Laguna. These were collected from host plants using forceps. Cytogenetic preparation of the eggs was done. Next, the qualitative observation of the mitotic cells and chromosomes was done using a light microscope. Chromosome counting was made possible by the Image J software application. Moreover, an interpretative drawing of the chromosomes and a karyogram were constructed from the chromosomes at pre-metaphase. Of the 30 mitotic cells examined, 22 showed a chromosome number range of 2n = 20 to 40. Eight (8) outlier cells showed a chromosome number range of 2n = 20 to 80. Representative diagram of chromosomes showed a mode, 2n = 30. On the other hand, the mean and median chromosome numbers were 2n = 38.2 and 2 n = 30, respectively. Based on this preliminary work, it is recommended that meiotic cells be observed in order to view sex chromosome behaviour. Also, more cells - preferably sampled from other Idea leuconoe populations - must be observed to substantiate the initial findings of this study.
