Scientists eradicate malaria-transmitting mosquitos using genetic engineering which make females infertile in new study which takes one step closer to wiping out the disease worldwide.

C. Ciaccia,  Daily Mail,  2021.
Malaria kills nearly 500,000 people globally every year, but scientists have now figured out a way to use CRISPR gene-editing technology to make female mosquitoes infertile, described as a 'game-changer' for ending the deadly disease. Researchers from Imperial College London, ...

Mosquito transgenics and courtship songs

H. Hurd,  BugBitten BMC,  2020.
As a female flies into the swarm she is detected by the sound of her wing beat and males identify females by a phonotactic response to the specific sound frequency produced by her wing beat. A male and female will then attune to each other by altering the frequency of their ...

Assessing the acoustic behaviour of Anopheles gambiae (s.l.) dsxF mutants: implications for vector control

M. P. Su, M. Georgiades, J. Bagi, K. Kyrou, A. Crisanti and J. T. Albert,  Parasites and Vectors,  13:507. 2020.
We analysed sound emissions and acoustic preference in a doublesex mutant previously used to collapse Anopheles gambiae (s.l.) cages.

Modelling the suppression of a malaria vector using a CRISPR-Cas9 gene drive to reduce female fertility

A. R. North, A. Burt and H. C. J. Godfray,  BMC Biology,  18:98. 2020.
Gene drives based on CRISPR-Cas9 technology are increasingly being considered as tools for reducing the capacity of mosquito populations to transmit malaria, and one of the most promising options is driving endonuclease genes that reduce the fertility of female mosquitoes. Here, ...

Identification and characterisation of a Masculinizer homolog in the diamondback moth Plutella xylostella

Harvey-Samuel, T., V. C. Norman, R. Carter, E. Lovett and L. Alphey,  Insect Molecular Biology,  2019:2019. 2019.
Recently, a novel sex-determination system was identified in the silkworm (Bombyx mori) in which a piRNA encoded on the female-specific W chromosome silences a Z-linked gene (Masculinizer) which would otherwise initiate male sex-determination and dosage compensation. ...
