Wolbachia Transinfection Via Embryonic Microinjection

Zhang, M., Xi, Z. ,  Methods in Molecular Biology,  2739. 2023.
The process of transferring Wolbachia from one species to another to establish a stable, maternally inherited infection in the target species is known as transinfection. The success of transinfection is primarily achieved through embryonic microinjection, which is the most direct ...

Measuring Host Fitness Effects and Transmission of Wolbachia Strains in Aedes aegypti Mosquitoes

Ross, P.A. ,  Methods in Molecular Biology,  2739. 2023.
Lines of Aedes aegypti mosquitoes infected with heritable Wolbachia bacteria are being developed and released for arbovirus control. Coordinated releases of lab-reared Wolbachia mosquitoes have reduced local disease incidence by spreading virus-blocking Wolbachia strains and by ...

Procedures for the Detection of Wolbachia-Conferred Antiviral Protection in Drosophila melanogaster

Chrostek, E.,  Methods in Molecular Biology,  2739. 2023.
Spread of Wolbachia infections in host populations may be enhanced by Wolbachia-conferred protection from viral pathogens. Wolbachia-infected Drosophila melanogaster survive the pathogenic effects of positive-sense single-stranded RNA virus infections at a higher rate than the ...

Use of Drosophila Transgenics to Identify Functions for Symbiont Effectors

Cortez, C.T., Murphy, R.O., Owens, I.M., Beckmann, J.F. ,  Methods in Molecular Biology,  2739. 2023.
Wolbachia, one of the most successful and studied insect symbionts, and Drosophila, one of the most understood model insects, can be exploited as complementary tools to unravel mechanisms of insect symbiosis. Although Wolbachia itself cannot be grown axenically as clonal isolates ...

Different mechanisms of X-ray irradiation-induced male and female sterility in Aedes aegypti

Zhang, H., Trueman, E., Hou, X. et al. ,  BMC Biology,  21. 2023.
Aedes aegypti (Ae. aegypti) is the major vector that transmits many diseases including dengue, Zika, and filariasis in tropical and subtropical regions. Due to the growing resistance to chemical-based insecticides, biological control methods have become an emerging direction to ...

Efficient sex separation by exploiting differential alternative splicing of a dominant marker in Aedes aegypti

Shih-Che Weng, Igor Antoshechkin, Eric Marois, Omar S. Akbari,  PLoS Genetics,  2023.
Only female mosquitoes consume blood giving them the opportunity to transmit deadly human pathogens. Therefore, it is critical to remove females before conducting releases for genetic biocontrol interventions. Here we describe a robust sex-sorting approach termed SEPARATOR ...

Advances and challenges in synthetic biology for mosquito control

Shih-Che Weng, Reem A. Masri, Omar S. Akbari,  Trends in Parasitology,  2023.
Mosquito-borne illnesses represent a significant global health peril, resulting in approximately one million fatalities annually. West Nile, dengue, Zika, and malaria are continuously expanding their global reach, driven by factors that escalate mosquito populations and pathogen ...

Repeat mediated excision of gene drive elements for restoring wild-type populations

Pratima R Chennuri, Josef Zapletal, Raquel D Monfardini, Martial Loth Ndeffo-Mbah, Zach N Adelman, Kevin M Myles,  bioRxiv,  2023.
We demonstrate here that single strand annealing (SSA) repair can be co-opted for the precise autocatalytic excision of a drive element. Although SSA is not the predominant form of DNA repair in eukaryotic organisms, we increased the likelihood of its use by engineering direct ...

Effects of different diets on Aedes aegypti adults: improving rearing techniques for sterile insect technique

Aynoanne Leandro Barbosa , Glayciane Costa Gois , Verenna Barros dos Santos , Aline Taiane de Macedo Pinto , Bianca Pires de Castro Andrade , Lucas Barbosa de Souza , Fernanda Hohana Almeida e Sá , Jair Fernandes Virginio and Mário Adriano Ávila Queiroz,  Bulletin of Entomological Research,  2023.
The aim was to evaluate the effect of different energy diets available in adulthood on the longevity, dispersal capacity and sexual performance of Aedes aegypti produced under a mass-rearing system. To evaluate the effects of diets in relation to the survival of the adult male ...

Utility of surveillance data for planning for dengue elimination in Yogyakarta, Indonesia: a scenario-tree modelling approach

Melanie Bannister-Tyrrell, Alison Hillman, Citra Indrian, Riris Andono Ahmad, Adi Utarini, Cameron P Simmons, Katherine L Anders, Evan Sergeant,  BMJ Global Health,  8. 2023.
Field trials and modelling studies suggest that elimination of dengue transmission may be possible through widespread release of Aedes aegypti mosquitoes infected with the insect bacterium Wolbachia pipientis (wMel strain), in conjunction with routine dengue control activities. ...

Meiotic drive, postzygotic isolation, and the Snowball Effect

Robert L. Unckless,  bioRxiv,  2023.
As populations diverge, they accumulate incompatibilities which reduce gene flow and facilitate the formation of new species. Simple models suggest that the genes that cause Dobzhansky-Muller incompatibilities should accumulate at least as fast as the square of the number of ...
