Hi Izaskun ,

Sterile Insect Technique or SIT is a technique use for arthopods to make them sterile. And somewhere it is related to inhibition of Sperm production or abnormal sperm. In this, basically the insects are exposed to Radiation.

Low oxygen environment favour the sterile insect longevity.

Hope it will be helpful.

Thanks for your help!

Regards,

Izaskun.
