The black soldier fly (Hermetia illucens) is a non-pest insect native to the Americas but now found worldwide, valued for its larvae’s ability to convert organic waste into protein-rich biomass and compost. It plays a major role in waste management and animal feed production.

Life Cycle
Eggs: Laid in clusters near decaying matter.
Larvae: The most important stage— consume organic waste, reducing volume by up to 50–60%.
Pupae: Transition stage before adulthood.
Adults: Live only about 5–8 days, do not feed, and are harmless (they don’t bite or spread disease).

When Larvae turns into Pupae and adult flies come out from Pupae when temperature is below 30°C and humidity above 80% RH , it goes towards the light and they need light to see blue/ green stripes on female BSF which attracts male BSF for the mating process. Since suitable temperature and humidity for BSF is not constant throughout the year.

Therefore, Pratheen Eco Solution treating biodegradable waste through BSF needs an incubator to maintain the suitable environment so the mating process can be cultivated throughout the year. And in current breeding chamber there is an obstacle i.e. choking of fogger due to hard water and formation of algae on cooling pads is reducing air flow.

Objectives:
To design a control algorithm of Incubator for BSF mating chamber to maintain temperature range 25°C to 30°C and humidity range 65% to 80% RH inside the mating chamber.

In April 2026, Pabal had an extreme weater condition of 40°C and 15% RH ambient air. So we are trying to model how we can keep our favourable condition in such extreme condition.

Idea discussion with Dr. Arun Dixit:

Idea 1

To model how Relative Humidity and temperature changes from centre of droplet to distance r.

Idea 2

How different size of droplet of rainfall humidify the air and how evaporation of moisture from soil contributes to relative humidity.

Idea 3

Using UV Humidifier to pass humid air in breeding chamber

Idea 4

Reverse Shower (fountain) since rate of evaporation depends upon size of droplet,wind speed,retention time and humidity of air.

Tried to create mathematical model of our condition but due to complexity I pivoted to do simulation on COMSOL Multiphysics and learning the software while working on it with the help of Google Gemini.
