Yes, this is theoretically possible, but it would be a highly complex and expensive undertaking. In order to achieve this, a scientist would need to edit the mosquito’s genome so that the mosquito’s offspring no longer carry the malaria-causing parasites. This could be done by introducing genes that would prevent the mosquito from being a good host for the malaria parasites, such as genes that make the mosquito resistant to the parasites or genes that make it difficult for the parasites to reproduce inside the mosquito. However, this technology is still in its early stages and much work would still need to be done before it could be put into practice.
