The 12-Year Hunt for Iowa's Rarest Insect

Here's the story of a 12-year scientific detective case that started completely by accident. In 2008, an entomologist in Iowa found a tiny, unfamiliar insect in one of her traps. It turned out to be Fitchiella robertsonii, a planthopper so rare it had never been seen in the state before. That single discovery kicked off a decade-long search.

The rare planthopper Fitchiella robertsonii on Indian grass, an insect found on native Iowa tallgrass prairies.

The 12-Year Hunt for an Insect Ghost

This one insect led two Iowa State scientists, Marlin Rice and M.J. Hatfield, on a mission. For years, they struggled, finding only two more specimens. The insect was a ghost.

Then came the breakthrough. After painstaking work, they figured out its primary host plant: Indian grass.

With this new lead, they clambered up steep, rocky prairies—the last remnants of native tallgrass habitats—to continue their search. In the end, they collected 219 specimens. That number might not sound like much, but it represents 90% of all F. robertsonii ever collected in the world. It was a massive leap in our understanding of a single, almost unknown species.

A Win for Science, A Warning for Our Planet

But this story doesn't have a simple happy ending. The scientists described the future for this planthopper as "tenuous at best."

Here's why: less than 0.1% of Iowa’s original native prairies remain. In one of their most productive search sites, the insect later completely vanished.

This is a powerful and sobering reminder that critical habitats are disappearing at an alarming rate, taking entire undiscovered worlds with them. The discovery was a huge win for science, but it's also a stark warning about the urgency of conservation.

My Perspective

From my perspective as an agricultural entomologist and in my role as Co-founder & Scientific Advisor at Agri Tej Media, this story is a perfect example of why basic research and taxonomy are so critical. This entire decade-long discovery only happened because one entomologist in 2008 was skilled enough to recognize something "unfamiliar." It proves that conservation isn't just about large, charismatic animals; it's about protecting entire ecosystems, which are home to countless undiscovered species and complex interactions, like the bee's sixth sense or the value of overlooked insects. We are in a race against time to document and understand this biodiversity before it's gone forever.

Beyond Bt Cotton: What's Holding Back India's GM Crop Revolution?

" India ranks 4th in the world for GM crop cultivation, yet only grows one. The question is: what’s holding us back?” This is one of the biggest paradoxes in modern Indian agriculture. Beyond Bt Cotton: What's Holding Back India's GM Crop Revolution? It has been nearly three decades since the first major genetically modified (GM) crops were commercially cultivated worldwide. Yet, as of today, only one GM crop is approved for commercial cultivation in India: Bt Cotton . The Case of GM Mustard (DMH-11): So Close, Yet So Far The most prominent example of this stagnation is GM Mustard (DMH-11). Despite being approved for environmental release by the Genetic Engineering Appraisal Committee (GEAC) back in October 2022, it is still not being commercially cultivated. Developed by the University of Delhi’s Centre for Genetic Manipulation of Crop Plants (CGMCP ) , DMH-11 contains genes from a soil bacterium that enable more efficient hybridization, boosting potential ...

Editing the Future: How CRISPR Gene Editing is Building Pest-Proof Crops in India

What if we could ‘edit’ a plant’s DNA like a document, deleting its vulnerability to pests before it’s even planted? This isn't science fiction; this is the CRISPR revolution, and it's taking firm root in Indian agriculture. CRISPR-Cas9 Gene Editing for Agriculture Forget what you know about traditional GMOs. The CRISPR-Cas9 technology acts like a molecular scalpel, allowing scientists to make precise, targeted edits to a plant's own genome, often without introducing any foreign genes. It’s a game-changer for developing resilient crops, and India's leading research institutions are harnessing its power. Pioneering Pest-Resistance in Indian Staples The work being done is not just theoretical; it's actively aimed at solving real-world problems for our farmers. Pest-Proofing Rice: Scientists at premier institutes like the National Institute of Plant Genome Research (NIPGR) and the ICAR-Indian Agricultural Research Institute (IARI), New Delhi , are developing rice va...

Integrated Pest Management: A Smarter Way to Protect Our Crops

Hello readers! 👋 Welcome to my very first post on this blog dedicated to the fascinating world of insects, pests, and the science that protects our crops! I’m Anka Pujitha, an entomology enthusiast passionate about sustainable agriculture. Today, let’s explore an approach that’s changing the way we manage pests — Integrated Pest Management (IPM). 🌿 What is IPM? Integrated Pest Management (IPM) is a science-based, eco-friendly method that combines different strategies to control pests effectively — while minimizing risks to farmers, consumers, and the environment. Instead of relying only on chemical pesticides, IPM uses a smart combination of methods : Cultural (e.g., crop rotation) Biological (e.g., using beneficial insects) Mechanical (e.g., traps, barriers) Chemical (only when absolutely needed, and in a targeted way) 🐛 Why is IPM important? Reduces pesticide use Protects beneficial insects like pollinators Prevents pest resistance Ens...

GST Rate Cuts: A Big Win for India's Farmers

The government has recently rolled out new GST reforms for the agriculture sector, and it’s good news for farmers. Many essential agricultural goods and inputs now have lower tax rates, with some dropping to just 5% or even becoming tax-free. Let's break down what's changed and what it means for the farming community. GST Reforms Benefit Indian Farmer Cheaper Farming Equipment and Machinery One of the biggest changes is the GST reduction on farm machinery. The tax on a wide range of equipment has been cut from 12% to 5% . This includes: Tractors (with engines under 1800 cc) Machines for soil preparation, cultivation, harvesting, and threshing Parts for tractors, like tyres and tubes, which saw a significant drop from 18% to 5% This makes it more affordable for farmers to invest in the tools they need to improve efficiency. Lower Costs for Fertilizers and Inputs The GST on key raw materials used to produce fertilizers—like Sulphuric acid, Nitric acid, and Ammonia—has been slash...

From Silk Waste to Superfood: How Silkworm Pupae are Revolutionizing Fish Farming

To solve one of the biggest problems in fish farming, scientists looked in the most unlikely place: the leftovers from silk production. What they found has the potential to make both the silk and fish industries more sustainable and profitable. Silkworm Pupae as a Sustainable Fish Feed Every year, the global silk industry generates nearly 200,000 metric tons of silkworm pupae as a byproduct. For decades, this "waste" was largely overlooked. Yet, it's a powerhouse of protein, with levels ranging from 50-70%. Groundbreaking new research confirms this byproduct isn't just a viable alternative to traditional fishmeal—it might actually be superior. A recent study evaluated silkworm pupae meal as a replacement for fishmeal in the diet of the popular Genetically Improved Farmed Tilapia (GIFT), a variety developed by institutions like WorldFish . The results were remarkable. What the Science Revealed The study showed clear, measurable benefits of incorporating silkworm pupae ...
