Sex separation of Aedes spp. mosquitoes for sterile insect technique application: a reviewB. M. Moran-Aceves, C. F. Marina, A. Dor, P. Liedo and J. Toledo, Entomologia Experimentalis Et Applicata, 10. 2021.
Separation of the sexes is necessary for the application of the sterile insect technique (SIT) in mosquitoes due to the hematophagous habits and disease vector activity of the females. In this review we analyze the history, current status, and future perspectives for the ... |

Using Moderate Transgene Expression to Improve the Genetic Sexing System of the Australian Sheep Blow Fly Lucilia cuprinaY. Yan, M. E. Williamson and M. J. Scott, Insects, 11. 2021.
The sterile insect technique (SIT) is a promising strategy to control the Australian sheep blow fly Lucilia cuprina, a major pest of sheep. We have previously developed a transgenic embryonic sexing system (TESS) for this pest to facilitate the potential SIT application. TESS ... |

How AI and mosquito sex parties can save the worldD. Takahashi, Ventura Beat, 2021.
Jerusalem-based Diptera.ai has figured out a way to use AI to fight the growing threat of mosquitoes, which are spreading malaria and viruses like Zika, dengue, and yellow fever. While the method for fighting mosquitoes has been around for decades, AI can take it to a new level ... |

Introduction of a cold sensitivity-conferring mutation into the RTA-Bddsx hybrid system of Bactrocera dorsalis for establishment of a thermally controllable homozygous lineS. M. Dai, C. Y. Huang and C. Chang, Pest Management Science, 7. 2021.
BACKGROUND For efficient control of the economically important fruit pest Bactrocera dorsalis, a hybrid system combining ricin toxicity and sex-related alternative splicing of the doublesex gene has been developed. This system exhibits the expected female-specific lethal effect; ... |

Determining the Sterilization Doses under Hypoxia for the Novel Black Pupae Genetic Sexing Strain of Anastrepha fraterculus (Diptera, Tephritidae)P. D. Giustina, T. Mastrangelo, S. Ahmad, G. Mascarin and C. Caceres, Insects, 12. 2021.
Our study reports for the first time the dose-sterility response under hypoxia for two different A. fraterculus strains. The pupae were derived from a bisexual strain (a Brazilian-1 population) and a recently developed genetic sexing strain (GSS-89). Two hours prior to ... |

White pupae phenotype of tephritids is caused by parallel mutations of a MFS transporterC. 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 ... |

Genetic sexing strains for the population suppression of the mosquito vector Aedes aegyptiP. Koskinioti, A. A. Augustinos, D. O. Carvalho, M. Misbah-ul-Haq, G. Pillwax, L. D. d. l. Fuente, G. Salvador-Herranz, R. A. Herrero and K. Bourtzis, Philosophical Transactions of the Royal Society B: Biological Sciences, 376:20190808. 2020.
Here, we report on the construction of two genetic sexing strains using red- and white-eye colour mutations as selectable markers. Quality control analysis showed that the Red-eye genetic sexing strains (GSS) is better and more genetically stable than the White-eye GSS. The ... |

A novel drug-inducible sex separation technique for insectsKandul, N. P., J. Liu, A. D. Hsu, B. A. Hay and O. S. Akbari, bioRxiv, 2019:2019.12.13.875716. 2019.Large sterile male releases are the gold standard for most insect population control methods and thus precise sex sorting is essential to the success of these technologies. Sex sorting is especially important for mosquito control because female mosquitoes bite and transmit ... |
