Major fly pest genetically modified in lab to produce more males

H. Dunning,  Imperial College London,  2021.
It has been predicted that the world's population will increase to over nine billion people by 2050, and that global food production will need to increase by around 70 percent to match this rate of change. Lead researcher Dr Angela Meccariello, from the Department of Life ...

Engineered sex ratio distortion by X-shredding in the global agricultural pest Ceratitis capitata

A. Meccariello, F. Krsticevic, R. Colonna, G. Del Corsano, B. Fasulo, P. A. Papathanos and N. Windbichler,  BMC Biology,  19:78. 2021.
Genetic sex ratio distorters are systems aimed at effecting a bias in the reproductive sex ratio of a population and could be applied for the area-wide control of sexually reproducing insects that vector disease or disrupt agricultural production. One example of such a system ...

White pupae phenotype of tephritids is caused by parallel mutations of a MFS transporter

C. M. Ward, R. A. Aumann, M. A. Whitehead, K. Nikolouli, G. Leveque, G. Gouvi, E. Fung, S. J. Reiling, H. Djambazian, M. A. Hughes, S. Whiteford, C. Caceres-Barrios, T. N. M. Nguyen, A. Choo, P. Crisp, S. B. Sim, S. M. Geib, F. Marec, I. Hacker, J. Ragous,  Nature Communications,  12. 2021.
Here, we use classical and modern genetic approaches to identify and functionally characterize causal wp(-) mutations in these distantly related fruit fly species. We find that the wp phenotype is produced by parallel mutations in a single, conserved gene. CRISPR/Cas9-mediated ...
