Since this is not my area of expertise, I searched Google under the key words "insect sterilization disadvantage" to get these possible sources:

You can do the same for "insect food irradiation." However, have you considered the possibility that the radiation effects will be passed up the food chain as other organisms eat the insects?

I hope this helps. Thanks for asking.
