Harnessing the power of insects to address 21st-century challenges in agriculture, medicine, and industry
What if I told you that some of today's most promising solutions to humanity's greatest challenges—from food security to antibiotic resistance—come from an source so small it often goes unnoticed? In laboratories around the world, scientists are partnering with nature's most abundant creatures: insects. These tiny organisms are being transformed into living factories that can produce sustainable protein, powerful medicines, and eco-friendly pest control solutions. Welcome to the fascinating world of insect biotechnology, where the line between pest and partner is being redrawn in petri dishes and research facilities globally.
As we face a growing population projected to reach 9 billion by 2050, alongside diminishing agricultural land and freshwater resources, the pressure to develop sustainable solutions has never been greater 8 . Insect biotechnology offers a compelling pathway forward, harnessing the remarkable biological capabilities of insects to address challenges across medicine, agriculture, and industry. This field, sometimes called "yellow biotechnology," represents one of the most exciting frontiers in 21st-century science 3 .
At its core, insect biotechnology involves using insects, their cells, or their molecules to develop products and services for human benefit 3 . Think of it as partnering with insects rather than fighting them. Unlike traditional approaches that view insects primarily as pests, this field recognizes their incredible potential as biological resources.
Using insect-derived compounds to develop new drugs and treatments
Creating sustainable pest control and enhancing crop production
Developing new materials and production methods
Did you know? With an estimated 1.9 million species, insects represent over 90% of all animal life forms on Earth, each with unique biological traits that can be harnessed 3 . This diversity represents a largely untapped reservoir of biological innovation.
Agriculture has been one of the primary beneficiaries of insect biotechnology. Traditional chemical pesticides have often caused collateral damage to ecosystems, but biotechnology offers more targeted approaches 9 .
The most famous example is Bt (Bacillus thuringiensis) technology. This soil bacterium produces crystal proteins called "Cry" proteins that are toxic to specific insect pests but harmless to humans and other animals 3 . Scientists have isolated the genes responsible for these proteins and inserted them into crops like cotton, corn, and potatoes, giving them built-in protection against devastating pests 3 . The result? Farmers can significantly reduce chemical pesticide use while maintaining yields.
Using genetic material to silence specific pest genes, disrupting their development or reproduction without harming beneficial insects 9
Developing targeted pesticides from bacteria, fungi, or plant extracts that specifically attack problem pests while sparing beneficial insects 9
By 2025, biotech pest control is projected to reduce pesticide use in agriculture by up to 40%, representing a significant environmental victory 9 .
Perhaps even more astonishing are the medical applications of insect biotechnology. Insects produce an array of antimicrobial compounds that are attracting attention as templates for new drugs, particularly important as antibiotic resistance grows 3 .
Insects produce short cationic peptides that rapidly kill target microorganisms, have broad activity spectra, and aren't active against mammalian cells—making them ideal candidates for overcoming drug-resistant bacteria 3
Specific components of manuka honey can stimulate immune responses and promote wound healing 3
Despite their unappealing reputation, maggots produce secretions that show promise for cleaning wounds and fighting infections 3
Insect cells have become valuable manufacturing platforms for producing complex proteins for medical use, often serving as a competitive alternative to mammalian cells 3
The industrial applications of insect biotechnology are equally impressive. Companies like InsectBiotech are pioneering ways to convert agricultural waste into valuable products using black soldier fly technology 2 . Their process yields:
This approach represents a classic example of the circular bioeconomy, where waste streams are transformed into valuable resources, reducing environmental impact while creating economic opportunities 8 .

In 2025, an 11-member research team from German universities conducted a groundbreaking study that addressed a fundamental question in insect science: How reliable are our research findings? 5 Their systematic investigation provided the first experimental evidence that insect behavioral studies, like other areas of science, can face reproducibility challenges.
The researchers implemented a 3×3 experimental design: three study sites (Münster, Bielefeld, and Jena) conducting three independent experiments on three insect species from different orders 5 . The species included:
Each experiment tested different aspects of insect behavior: the effects of starvation on sawfly larval behavior, color-based substrate choice in grasshoppers, and niche preference in flour beetles 5 .
The research team followed rigorous protocols, standardizing experimental setups and environmental conditions across laboratories as much as possible 5 . Despite these careful controls, the results revealed significant variability.
Using random-effects meta-analysis to compare consistency across laboratories, the team found that while they could successfully reproduce the overall statistical treatment effect in 83% of replicate experiments, the replication of overall effect size dropped to just 66% of replicates 5 . Depending on the definitions and methods used to determine reproducibility, non-reproducible results ranged from 17% to 42% .

These findings are particularly significant because insect studies typically use larger sample sizes than many other biological studies, which should theoretically provide more robust results . The fact that reproducibility challenges still emerged suggests that even well-designed insect studies can produce results that are somewhat laboratory-specific.
The researchers identified several factors contributing to this variability:
This doesn't mean insect research is unreliable—in fact, reproducibility in these insect studies was higher than in many other scientific fields . Instead, it highlights the importance of acknowledging biological variation and implementing practices that improve reliability.
| Insect Species | Behavior Tested | Reproducibility of Statistical Effect | Reproducibility of Effect Size |
|---|---|---|---|
| Turnip sawfly | Post-starvation behavior | High in activity measures | Lower in manual handling tests |
| Meadow grasshopper | Color-based substrate choice | Moderate across labs | Varied between experienced vs. inexperienced labs |
| Red flour beetle | Niche preference | Generally consistent | Affected by environmental factors |
Modern insect biotechnology relies on a sophisticated array of reagents and technologies. Here are some of the key tools powering this field:
| Tool/Reagent | Function | Application Example |
|---|---|---|
| CRISPR-Cas9 | Gene editing system that allows precise modification of insect genomes | Creating genetically modified insects for research or control purposes |
| RNAi technology | Silences specific genes to study their function or control pest populations | Developing targeted pest control strategies that avoid harming beneficial insects |
| Baculovirus expression system | Uses insect viruses to produce complex proteins in insect cells | Manufacturing pharmaceutical proteins requiring sophisticated folding |
| Antimicrobial peptides | Small proteins with potent activity against bacteria, fungi, and viruses | Developing new antibiotics to combat drug-resistant infections |
| Bt (Bacillus thuringiensis) toxins | Natural insecticidal proteins with specific activity against target pests | Engineering pest-resistant crops or creating biopesticides |
Advanced gene editing technologies like CRISPR-Cas9 allow precise modifications to insect genomes, enabling researchers to study gene function and develop insects with beneficial traits.
High-throughput sequencing, proteomics, and metabolomics provide comprehensive insights into insect biology, revealing new molecules and pathways with potential applications.
Despite its promise, insect biotechnology faces several significant challenges on the path to widespread adoption:
The legal framework for genetically modified insects and insect-derived products remains complex and varies significantly between countries 8
Consumer willingness to embrace insect-derived products, particularly for food and medicine, requires ongoing education and transparent communication 8
As highlighted in the German study, ensuring consistent and reproducible results across different laboratories remains challenging 5
Moving from laboratory successes to industrial-scale production presents technical and economic challenges
The future direction of the field likely involves greater integration of bioinformatics and artificial intelligence to interpret complex biological data and guide research priorities 8 . Additionally, the concept of the circular bioeconomy—where waste streams become resources—will probably drive innovation in insect-based waste conversion and valorization 2 8 .
Insect biotechnology represents a paradigm shift in how we view our relationship with the natural world. By recognizing insects not as enemies to be eliminated but as partners in innovation, we unlock a treasure trove of biological solutions to 21st-century challenges.
From the antimicrobial peptides that might solve our antibiotic resistance crisis to the insect-based recycling systems that could transform waste into valuable resources, these tiny creatures are making an outsized impact on technology and sustainability. As researcher Prof. Helene Richter's work demonstrates 5 , maintaining scientific rigor while embracing biological diversity will be key to advancing this exciting field.
The next time you see an insect, remember: within that tiny body might lie the solution to one of humanity's greatest challenges. Insect biotechnology is proving that when it comes to innovation, size really doesn't matter.
