Butterflies increase in Sikkim
Increased activity by butterflies near hot sulphur springs in Sikkim has opened up a field of study of pollination for flowers and crops if they are sprayed with sulphur compounds, which are an attractant.
Preliminary analysis of the water from the hot springs has revealed that it contain a high concentration of sulphur and insects like dragonflies, butterflies, wasps and different types of moths were attracted towards it because of the sulphurous smell.
Saurav Das, an assistant professor of Sikkim University working on this study, said: "We have placed flowers and vegetables of different kinds in a lab after spraying them with sulphur attractants and are studying which kind of insects are attracted and which insects repelled.
The study will help us establish an efficient pollination cycle for flowers and different crops.
