Infertility is the Latest Weapon Against Pests

Researchers have pioneered a way to use infertility to control pest populations, according to Vaughan Elder from

The technique involves introducing a genetically compromised ‘trojan female’ into the population to give birth to sterile male offspring.

The approach takes advatange of naturally occurring mutations that have limited impact on females but a strong impact on males.

Researchers said the finding could be a game changer when it comes to controlling pests.

Traditional pest control methods are often lethal, costly, inefficient and cruel. This new approach addresses many of those issues and could apply to a range of pests including rats and mosquitoes.

The technique does not require artificial genetic modification and is reversible. Females acquire the mutation in a breeding program held in captivity and are then released into the wild.

With rats spoiling up to 15% of food supplies in some countries and malaria killing more than a million people each year, this new approach to pest control may have a huge impact on pest control in the future.
