Sterilize & release programs for feral cats work; the sterilized cats compete for the same resources as unsterilized ones, but are more effective and longer-lived because they don't have to support reproduction. This not only means that the sterilized cats won't reproduce, but the unsterilized ones will have a harder time, and reproduce less.

It works better than trapping & killing.

It seems likely that capturing cats, sterilizing them, and releasing them would have a larger impact than simply releasing a large number of sterile cats. It's also much easier to do in appreciable numbers, relative to the wild population, and it doesn't actually lead to extinction, just some additional population control. I don't think it is a good fit for mosquitos.

I once heard a modified version of the plan, where you release male mosquitos with a "driving Y chromisome" - that is, a Y chromisome with a mutation that leads to male offspring. Supposedly this should spread in a population even when but eventually leads to extinction.

But presumably the female mosquitos will eventually learn to avoid the males with the modified Y chromosome?

it has to be said - if non-sterile mosquitos are having a hard time surviving because sterile mosquitos drank up all the blood - we're probably going to suffer more than they will

Only female mosquitos drink blood.

Very interesting. That's what we're also doing to human populations.
