The Queen of Chemical Ecology

srinivas_blog.png

by Srinivas Rao – It has been since almost 3 years since I joined as a technical person to handle Gas Chromatography-Mass Spectrometry (GCMS) Instrument.

My journey in this lab started with the Jyothi Nair’s Project of Blackbuck samples from Dr. Uma Ramakrishnan’s  lab and followed by more than 10+ collaborative works in progress.

It gives me an immense pleasure to work on samples from Volatile Organic Compounds (VOCs) from dung piles of Blackbuck, Coffee plants, Tecoma flowers,  Wood samples, Transgenic potato and tomato plants, Essential oils of Artemisia extracts, Species of oak borer larva, Butterfly caterpillars, Areca nut beetles, Volatiles collected from interactions between  endophytic Trichoderma sp. fungi, Butterfly pheromones, Cuticular hydrocarbons from Honeybees, Insect pheromones, Mosquito repellants, and more!

With a wide range of samples to work on,, I am excited to analyze the VOCs from different species of plants and animals to know much more aspects about their chemistry and biology, which in turn, open new and exciting opportunities for empirical research in Chemical Ecology.

Let’s look at the number of samples so far:

It has been 03 years  that our Instrument has been functioning, till now the samples run is:

2015: 1201 samples
2016: 2700
2017: 2257
2018: 798 and counting!

With more than 6000+ samples analyzed from dawn to dusk, this robust GCMS Instrument shall be the Queen of Chemical Ecology!

New Collaborative Publication!

The NICE Lab is pleased to announce the release of our newest publication in collaboration with Uma Ramakrishnan at NCBS on in situ sampling of Blackbuck volatiles related to lek mating. You can read the study here.

Special Congratulations to Jyothi Nair, member of the Ramakrishnan lab and honorary member of the NICE lab as well as VS Pragadheesh, former postdoc and current scientist at IICB in Kolkata.

The Fugacious Life Story of the Mayfly

Editor’s Note:  Our Geetha is quite the artist – both with pen and SEM! by Geetha GT – Mayflies are aquatic insects from a very old insect group called Palaeoptera. They are well known as bioindicators of water pollution. Mayflies have three stages in life, first as an egg (Image 1) in a pond or lake, then they hatch into nymphs (naiad,…

Apis Midwife

by Abhinav Raina  – Our work in the NICE Lab involves studying the honeybee species Apis Dorsata and the effects of airborne pollution on its physiology. As part of our work, we compare the physiological responses of these bees from different parts of Bangalore based on the pollution levels in their environment. One of the experiments we wanted to conduct…

For Love of Insects

by Shannon – Near the end of his career, my advisor, Tom Eisner, wrote a famous book entitled “For Love of Insects“, about his passion for our six-legged cohabitants on this planet. From beetles with boiling butts to warmongering termites, Tom showed us, with passion and sheer delight, the incredible natural world we live in.

Both Tom and I grew up in an environment where insects were friends. From his childhood in Uruguay to mine in Northern New York State, both of us grew up fascinated by the myriad of forms of insects – the grace of a butterfly, the cunning of a mantis, the strength of a beetle.  Some insects were harmful, yes.  Some stung or produced noxious chemicals when you stepped on them.  But the vast majority were harmless to humans and a quick walk in my backyard in DePeyster let me know how important each insect was to the “vast communicative interplay” (Tom Eisner’s words) on this planet.

Today things are different.  Many children don’t have the same opportunities that Tom and I had to experience nature as a child.  The World Health Organization tells us that as of 2007, more than 50% of the world lives in towns and cities. By 2050, that will have climbed to 70%.  In the megacity of Bengaluru, we see this trend acutely. In 40 years, Bangalore has grown from a city of 2 million to 12 million – a staggering increase!  Each year more and more people leave their farms and villages for the promise of employment and opportunities here in the city.

Our relationship with Nature, and especially with insects, is completely different in the city. Cities are for people, filled with dwellings and structures for humans, not insects. Insects are “bad” in a house – they are the cockroaches in the bathroom, the flour beetles in the kitchen, the flies on your dinner plate. Mosquitoes carry disease.  Even honeybees are feared – they can sting!  A child growing up in the city often learns early on that insects are something to fear and avoid.  Insects represent disease and uncleanliness.

Of course, the insects we consider pests are only a tiny fraction of the 5-7 million insect species estimated on this planet. Most insects are either beneficial or important to our ecology in other ways as part of the food chain or reducing organic waste on the planet. Without insects, we would not exist.

That’s why it is so important for us to show our children, especially those in cities, the beauty and importance of insects.  A child who is taught the wonder of Nature will grow to become an adult who loves and cares for this planet.  On Thursday, April 12, our lab organized an “Insect Walk” for 50 Bengaluru children attending the VIVRITI Edu  Summer Camp.  The children took a walk around our lovely campus at NCBS, collected insects, and then observed them under the microscope.  They got to see our lab and how we research these lovely animals, and then watched a short film on insects where they were quizzed on the importance of insects to our lives.

This is the third year we have held this program.  It never ceases to amaze me how children who come in squeamish and anxious about insects quickly lose their fear amongst the beauty of the creatures they find.  Butterflies, crickets, grasshoppers, stinkbugs, lady beetles, fruit flies, ants, and bees are all carefully carried to the lab for inspection, and then released back to their homes.  Our hope is that they hold on to their excitement, and teach their friends how important these tiny animals are.  When they grow up, may they take this love with them and help to preserve a world that so desperately needs their attention.

Special thanks to Hinal Kharva for her hard work organizing this event!
