Exactly, it follows a very similar logic, but when it comes to population control, an infertility gene is what’s generally used.
Gene drives rely on CRISPR/Cas9 technology, which acts as a tool to ensure nearly 100% of offspring inherit the new trait.
In our case;
1- A female infertility gene is inserted into the eggs of the target species.
2- Once these insects are released into the wild, they mate with wild ones, and the CRISPR system cuts the normal gene from the wild parent & replaces it with the infertility gene.
3- This way, the males remain fertile and act as carriers to spread the trait through the population; however, because the females carrying this code become unable to lay eggs, the population quietly and naturally declines over time.

Wouldn’t this have a massive impact on the ecosystem? Crop pests are often beneficial when not on the crop
