C.A.T.T.

Controlled Atmosphere Temperature Treatment

How does it work !

Like all other aerobic organisms insects also obtain oxygen (O2) from their environment in order to survive. All the insects carry out the same set of metabolic reactions as other animals for example glycolysis, Kreb's cycle, and the electron transport system to convert nutrients like carbohydrates into the chemical bond energy of ATP. The final step of these metabolic reactions is the reaction of oxygen atoms with hydrogen ions to produce water accompanied with the release of energy that is captured in a phosphate bond of ATP. An insect's respiratory system is the biological system with which it introduces respiratory gases to its interior and performs gas exchange.

Air enters the respiratory systems of insects through a series of external openings called spiracles. These external openings, which act as muscular valves in some insects, lead to the internal respiratory system, a densely networked array of tubes called tracheae. This network of transverse and longitudinal tracheae equalizes pressure throughout the system. It is responsible for delivering sufficient oxygen (O2) to all cells of the body and for removing carbon dioxide (CO2) that is produced as a waste product of cellular respiration. The respiratory system of insects (and many other arthropods) is separate from the circulatory system. 

By changing the conditions of the atmosphere , the respiratory system of the insect will be affected and the insect will not survive. Using the right O2 / CO2 conditions, temperature and humidity the mortality rate will reach 100%. 

Advantages of C.A.T.T.

  1. non chemical treatment

  2. high mortality rate

  3. no chemical residues or chemical waste

  4. no resistent development towards treatment
