The influence of the host plants and artificial food on the life cycle of endangerd species of…

Troides helenea is one of the Lepidoptera species that rare and protected. Based on Convention on International Trade in Endangered Species (CITES), this species categorized in CITES Appendix II. Species that belong to this category are permitted to be utilized on research, educational activities or as the scientific collection in museum. One of the causal factors of population decline of T. helena is the least number of host plants. Therefore, this research conducted to discover the alternative feed by comparing the effect of natural feed and synthetic feed giving on the length of T. helena life cycle. The natural feed that used was Aristolochia tagala (jungle vine) which is the natural host plant of T. helena in the nature, meanwhile the synthetic feed that used was the feed that formulated. The life cycle period T. helena which fed by using the natural feed and synthetic feed is statistically tested by using T-test. The result of T-test showed that there were life cycle periods difference between the individual which fed by using natural feed and the individual which fed by using synthetic feed. The individual life cycle which fed by using natural feed was shorter than the individual which fed by using the artificial food.

Title: Troides Helena Artist: knpandit2003 ( http://bit.ly/2Xf3lNE ) Uploaded Date: April 18, 2019 at 04:48AM Description: Troides Helena, the common birdwing, is a butterfly belonging to the family Papilionidae. It is essentially a forest species, found in forested areas as well as garden and parks where its host plants are cultivated. This beautiful butterfly is capable of flying long distances and at considerable height in a bird-like manner. In India, these beautiful butterflies are found in North-east region including Sikkim, West Bengal and Orissa. I found this adult male species stops to feed at flowers and observed it flutters its forewing whilst its hind wings kept relatively still. Its pleasant beauty mesmerizes me and I bagged it in frame without delay. Hope, it will get favour on visiting my galleries; have a nice day friend :) Follow me on: Facebook: http://bit.ly/2g8FFIj Flickr: http://bit.ly/2gQRdhk
