Ants

Ants are remarkable organisms whose complex social behaviour makes them powerful models for biological research. In our lab, we investigate the genetics and molecular mechanisms that determine how ants develop as males or females. Some ant species have evolved unusual reproductive systems in which cells with different genomes or even different sexual identities can coexist within the same individual, offering unique opportunities to study fundamental biological processes.

To ensure the wellbeing of the colonies, ants are kept in specially designed artificial nests located in climate-controlled rooms. These facilities allow researchers to maintain stable temperature, humidity, and lighting conditions that support natural colony behaviour. The nests remain in the dark—just as in the wild—while the surrounding environment is kept quiet and stable.

All ant containers are coated with safe anti-escape barriers, and every colony is placed in an additional containment box. This double-layered system prevents accidental escapes and ensures secure housing, in accordance with established safety and environmental protection guidelines.

 

Laboratory colonies are provided with a varied diet that reflects their nutritional needs. Their food includes freeze-killed insects such as house flies, specialized protein gels, honey water, and occasional supplements such as canned tuna or peanut butter.

This varied diet provides carbohydrates, proteins, and micronutrients in proportions similar to what ants encounter in nature. Fresh water is available at all times.

 

 

 

For certain molecular and genomic studies, queens are gently removed from their nests so that eggs can be collected. These procedures follow established protocols designed to minimise stress and disturbance to the colony. Ant eggs are carefully handled under a microscope—often arranged using a soft watercolour brush—to prepare them for microinjection or other analyses.

Our goal is always to maintain healthy, thriving colonies while advancing our understanding of the remarkable biological systems that ants have evolved.
