How Technology is Transforming the World of Entomology

Entomology is the scientific study of insects, one of the most diverse and fascinating groups of animals on Earth. Insects have been around for over 400 million years and have adapted to almost every environment and ecological niche. They play vital roles in pollination, decomposition, biological control, food webs, and human health.

But how do entomologists study these tiny creatures? What tools and techniques do they use to observe, identify, classify, and understand them? And how are technological advances changing the way entomologists conduct their research and communicate their findings?

In this blog post, we will explore some of the tech applications in insect research that are revolutionizing the field of entomology. We will look at how digital microscopy, insect identification apps, and drones are helping entomologists to discover new species, monitor insect populations, and protect crops from pests.

Digital Microscopy

One of the most important tools for entomologists is the microscope. Microscopes allow entomologists to examine the morphology, anatomy, and behavior of insects at high magnification and resolution. However, traditional microscopes have some limitations, such as being bulky, expensive, and requiring specialized skills and equipment to operate.

Digital microscopy is a technology that uses digital cameras and software to capture and process images of insects. Digital microscopy has several advantages over conventional microscopy, such as:

  • It is more portable, affordable, and accessible. Digital microscopes can be attached to smartphones or tablets and used in the field or in the classroom.
  • It allows for image enhancement, manipulation, measurement, and annotation. Digital microscopes can adjust brightness, contrast, color, focus, and zoom levels. They can also measure dimensions, angles, areas, and volumes of insect structures. They can also add labels, notes, arrows, or other annotations to the images.
  • It enables image sharing, storage, and analysis. Digital microscopes can store images on memory cards or cloud services. They can also share images via email or social media platforms. They can also use software to analyze images for pattern recognition, classification, or identification.

Digital microscopy has many applications in entomology. For example:

  • It can help entomologists to document insect diversity and discover new species. Digital microscopy can capture detailed images of insect specimens that can be used for taxonomic purposes. It can also help to create digital collections of insect images that can be accessed by researchers and the public.
  • It can help entomologists to study insect behavior and ecology. Digital microscopy can record videos of insect movements and interactions that can be used to understand their behavior and ecology. It can also help to monitor insect activity and abundance in different habitats and seasons.
  • It can help entomologists to educate and engage the public. Digital microscopy can provide stunning visuals of insect morphology and beauty that can be used to inspire curiosity and appreciation for insects. It can also help to communicate scientific concepts and findings to a wider audience.

Insect Identification Apps

Another challenge for entomologists is to identify insects. There are over one million described species of insects in the world, but many more are still unknown or poorly studied. Identifying insects can be difficult because they are often small, cryptic,
or variable in appearance.

Insect identification apps are smartphone applications that use artificial intelligence (AI) to identify insects from photos. Insect identification apps have several benefits over traditional identification methods such as keys or guides:

  • They are more convenient and user-friendly. Insect identification apps only require a smartphone with a camera and an internet connection. They do not require prior knowledge or experience in entomology. They can also provide instant feedback and information about the identified insect.
  • They are more accurate and reliable. Insect identification apps use machine learning algorithms that are trained on large datasets of insect images. They can recognize subtle features and variations that may be overlooked by human eyes. They can also update their databases with new information and corrections.
  • They are more interactive and collaborative. Insect identification apps allow users to submit their photos and observations to online platforms where they can be verified by experts or other users. They can also access other users’ photos and observations from around the world. They can also participate in citizen science projects or challenges that involve collecting data on insects.

Insect identification apps have many applications in entomology. For example:

  • They can help entomologists to identify insects faster and easier. Insect identification apps can save time and effort for entomologists who need to identify large numbers of insects or unfamiliar insects. They can also help to avoid errors or misidentifications that may affect the quality of their research.
  • They can help entomologists to discover new species or distribution records. Insect identification apps can help to detect rare or undescribed insects that may be overlooked by conventional methods. They can also help to map the geographic range and occurrence of insects across different regions and countries.
  • They can help entomologists to engage and educate the public. Insect identification apps can encourage people to observe and learn about insects in their surroundings. They can also help to raise awareness and interest in insect diversity and conservation.


A third challenge for entomologists is to monitor insect populations and movements. Insects are often affected by environmental factors such as climate change, habitat loss, pollution, or invasive species. Monitoring insects can help entomologists to understand how these factors impact their survival, distribution, and interactions.

Drones are unmanned aerial vehicles (UAVs) that can fly autonomously or remotely controlled. Drones have several features that make them useful for entomological research, such as:

  • They are versatile and adaptable. Drones can be equipped with different sensors and cameras that can capture various types of data, such as optical, thermal, multispectral, or hyperspectral images. They can also be modified with different attachments, such as nets, traps, or dispensers.
  • They are efficient and cost-effective. Drones can cover large areas and collect high-resolution data in a short time. They can also access remote or difficult locations that may be impractical or dangerous for humans. They can also reduce labor and material costs compared to traditional methods.
  • They are non-invasive and environmentally friendly. Drones can fly at high altitudes or distances that minimize disturbance or damage to insects and their habitats. They can also reduce noise and emissions that may affect wildlife or human health.

Drones have many applications in entomology. For example:

  • They can help entomologists to survey and sample insect populations. Drones can capture images or videos of insect abundance and diversity in different habitats and landscapes. They can also collect insect specimens using nets or traps that can be analyzed for identification or molecular studies.
  • They can help entomologists to track and model insect movements. Drones can record the flight paths and trajectories of insects that migrate or disperse over long distances. They can also measure the environmental variables that influence insect movements, such as temperature, humidity, wind, or vegetation.
  • They can help entomologists to manage and control insect pests. Drones can detect and map the distribution and damage of insect pests on crops or forests. They can also deliver biological agents or pesticides that target specific insect pests while minimizing harm to non-target organisms.


Technology is transforming the world of entomology by providing new tools and techniques for studying insects. Digital microscopy, insect identification apps, and drones are some of the tech applications in insect research that are helping entomologists to discover new species, monitor insect populations, and protect crops from pests.

These technologies are not only advancing the scientific knowledge and understanding of insects, but also enhancing the public appreciation and awareness of their importance and diversity.
