LIFESTYLE NEWS - Most people know mosquitoes as tiny insects that bite, cause itchy skin and can transmit malaria. Few, however, think about what happens inside the laboratories where scientists spend years studying them.
What happens inside a mosquito laboratory?
Behind secure laboratory doors, mosquitoes are carefully raised and studied to help researchers better understand one of Africa’s greatest public health challenges – malaria.
In the run-up to World Mosquito Day, Dr Alekos Simoni, Technical Support Specialist at Target Malaria, shared 10 things you may not know about mosquito laboratories.
1. Mosquitoes have their own nurseries
Every mosquito begins life as an egg. In laboratories, scientists carefully collect eggs and place them in controlled environments where they hatch into larvae before developing into adults.
Every stage of the mosquito life cycle is closely monitored to maintain healthy colonies for research.
2. Mosquito research requires precision
Researchers carefully collect tiny mosquito eggs before they are used in experiments. The process requires patience, skill and steady hands because the eggs are extremely delicate.
3. Timing is everything
When developing genetically modified mosquitoes for research, scientists work within a narrow window of time.
Microinjection must be completed soon after eggs are laid. If it is done too early, the embryos may be too fragile, while waiting too long can make them too firm for the procedure to succeed.
4. Mosquitoes are studied under powerful microscopes
Many laboratory procedures are carried out using high-powered microscopes.
Specialised equipment allows scientists to examine mosquito embryos, larvae and adults in detail that cannot be seen with the naked eye.
5. Some mosquitoes glow under special light
One of the fascinating aspects of mosquito research occurs after successful genetic modification.
Scientists can include a fluorescent marker in the genetic material. When illuminated under specialised equipment, successfully modified mosquito larvae glow, allowing researchers to identify them.
6. Most mosquito embryos do not survive
Developing genetically modified mosquitoes is a highly specialised process, and many embryos do not survive the delicate injection procedure.
Scientists continually refine their techniques to improve success rates while maintaining rigorous laboratory standards.
7. Temperature can determine whether a colony survives
Mosquitoes are surprisingly sensitive to their surroundings.
Laboratories carefully regulate temperature, humidity and light cycles to create stable conditions for mosquito colonies.
Even small environmental changes can affect their survival and behaviour.
8. Some mosquito colonies have been maintained for years
Scientific research does not happen overnight.
Some mosquito colonies are maintained across multiple generations, allowing researchers to study biological characteristics and evaluate potential innovations over time.
9. One mosquito can produce hundreds of eggs
A single female mosquito can lay hundreds of eggs during her lifetime.
Understanding mosquito reproduction is fundamental to malaria research because it helps scientists investigate how mosquito populations respond to different interventions.
10. Every discovery begins with understanding the mosquito
Before potential malaria innovations can be considered, scientists must first understand the insect itself.
From studying mosquito biology and behaviour to evaluating new approaches under controlled laboratory conditions, every step is guided by evidence, rigorous testing and responsible scientific practice.
Making malaria research more accessible
As researchers continue exploring complementary tools to help reduce malaria transmission, laboratory research remains an essential first step in understanding whether new approaches are safe and appropriate for further study.
“For those curious to experience this work first-hand, Target Malaria: The Game is now available as a free mobile app for both iOS and Android, as well as on desktop,” says Dr Simoni.
“Players can step into the role of a molecular biologist, using the same principles employed in real laboratories to perform microinjections and identify genetically modified mosquito larvae through transgenic screening.
“The game was developed to make complex science more accessible while inspiring greater understanding of malaria research.”
Dr Simoni adds that players can also explore behind the scenes inside a mosquito laboratory to see the expertise and care involved in conducting this research.
