Eating mosquitoes is not a common practice, and it's not advisable due to several reasons. While there are various insects consumed as food in different cultures around the world, mosquitoes are generally not considered a suitable or safe food source for human consumption.

Firstly, mosquitoes can carry and transmit diseases such as malaria, dengue fever, Zika virus, and more. Consuming mosquitoes, even after roasting, may not eliminate the risk of disease transmission, as the heat may not destroy all pathogens.

Secondly, the genetic modifications you mentioned, aimed at reducing the mosquito population and their ability to transmit diseases, are typically implemented for controlling mosquito-borne diseases. These modifications are not intended to make mosquitoes safe or suitable for human consumption. Eating genetically modified mosquitoes would likely introduce additional risks and uncertainties.

In summary, while the video you saw might have been intriguing, it's essential to exercise caution when considering unconventional food sources, especially those that pose potential health risks. It's always advisable to rely on well-established and safe sources of nutrition. If you have concerns or questions about a particular claim or practice, it's a good idea to consult with experts in the field or refer to reputable sources of information.
