Vertical and Horizontal Transmission in Paratransgenic Anopheles Mosquitoes

Wang et al. (2017) report results in Science that appear to make significant progress toward solving one of the more challenging problems associated with using paratransgenic approaches for sustainable insect phenotype modification. Paratransgenesis is an interesting concept involving the genetic […]

Driving Transgenes with Disassortative Mating

Pike et al. (2017) in a recent publication in Science describe a novel approach to rapidly increasing transgene frequencies in mosquito populations (‘gene drive’) for the purposes of reducing or eliminating Plasmodium transmission. There is increasing attention within the insect […]

Anopheles gambiae

Controlling Malaria Mosquitoes With Genetics

A chemical-free eradication method for the human malaria mosquito, Anopheles gambiae, that is self-sustaining and requires no additional inputs beyond ‘pushing the button’ to get it started, sounds fantastic. For geneticists it has not been terribly difficult to think of […]
