Efficacy of Wolbachia-based mosquito control: Predictions of a spatially discrete mathematical model

David Dye, John W. Cain,  PLoS One,  19. 2024.
Wolbachia is an endosymbiont bacterium present in many insect species. When Wolbachia-carrying male Aedes aegypti mosquitoes mate with non-carrier females, their embryos are not viable due to cytoplasmic incompatibility. This phenomenon has been exploited successfully for the ...

PSRs: Selfish chromosomes that manipulate reproductive development

Xinmi Zhang, Patrick M. Ferree,  Seminars in Cell and Developmental Biology,  159-160:66-73. 2024.
B chromosomes are intriguing “selfish” genetic elements, many of which exhibit higher-than-Mendelian transmission. This perspective highlights a group of B chromosomes known as Paternal Sex Ratio chromosomes (PSRs), which are found in several insects with haplo-diploid ...

CRISPR-mediated germline mutagenesis for genetic sterilization of Anopheles gambiae males

Smidler, A.L., Marrogi, E., Kauffman, J. et al.,  Scientific Reports,  14. 2024.
Rapid spread of insecticide resistance among anopheline mosquitoes threatens malaria elimination efforts, necessitating development of alternative vector control technologies. Sterile insect technique (SIT) has been successfully implemented in multiple insect pests to suppress ...

Efficacy of Wolbachia-mediated sterility to reduce the incidence of dengue: a synthetic control study in Singapore

Jue Tao Lim, Somya Bansal*, Chee Seng Chong*, Borame Dickens, Youming Ng, Lu Deng, Caleb Lee, Li Yun Tan, Grace Chain, Pei Ma, Shuzhen Sim, Cheong Huat Tan, Alex R Cook, Lee Ching Ng,  The Lancet Microbe,  2024.
Our study comprised an at-risk population of 607 872 individuals living in intervention sites and 3 894 544 individuals living in control sites. Interventions demonstrated up to 77·28% (121/156, 95% CI 75·81–78·58) intervention efficacy despite incomplete coverage ...

Acetylcholine esterase of Drosophila melanogaster: a laboratory model to explore insecticide susceptibility gene drives

Hernandes, N., Qi, X.M., Bhide, S., Brown, C., Camm, B.J., Baxter, S.W. and Robin, C.,  Pest Management Science,  2024.
One of the proposed applications of gene drives has been to revert pesticide resistant mutations back to the ancestral susceptible state. Insecticides that have become ineffective because of the rise of resistance could have reinvigorated utility and be used to suppress pest ...

Introduction of Aedes aegypti mosquitoes carrying wAlbB Wolbachia sharply decreases dengue incidence in disease hotspots

AA Hoffmann, NW Ahmad, WM Keong, CY Ling, NA Ahmad, N. Golding, N. Tierney, J. Jelip, PW Putit, N Mohktar, SS Sandhu, LS Ming, et al.,  iScience,  2024.
Partial replacement of resident Aedes aegypti mosquitoes with introduced mosquitoes carrying certain strains of inherited Wolbachia symbionts can result in transmission blocking of dengue and other viruses of public health importance. Wolbachia strain wAlbB is an effective ...

The haplolethal gene wupA of Drosophila exhibits potential as a target for an X-poisoning gene drive

Lawler, Clancy D ,Parra Nuñez, Ana Karla ,Hernandes, Natalia ,Bhide, Soumitra ,Lohrey, Isabelle ,Baxter, Simon ,Robin, Charles,  G3 Genes Genome Genetics,  jkae025. 2024.
We examine this ‘X-poisoning’ strategy by targeting four of the 11 known X-linked haplolethal/haplosterile genes of Drosophila melanogaster with CRISPR/Cas9. We find that targeting the wupA gene during spermatogenesis skews the sex ratio so fewer than 14% of progeny are ...

Genome editing in pests: basic science to applications

Chen, X., Palli, S.R.,  Journal of Pest Science,  2024.
Recent developments in sequencing technologies produced enormous data on gene sequences and the identity of genes in many pest insects and disease vectors. However, the function of many of these genes is unknown. Functional genomics studies to uncover gene function in pest ...

Deep orange gene editing triggers temperature-sensitive lethal phenotypes in Ceratitis capitata

Sollazzo, G., Nikolouli, K., Gouvi, G. et al.,  BMC Biotechnology,  24. 2024.
The Mediterranean fruit fly, Ceratitis capitata, is a significant agricultural pest managed through area-wide integrated pest management (AW-IPM) including a sterile insect technique (SIT) component. Male-only releases increase the efficiency and cost-effectiveness of SIT ...

Anti-CRISPR Anopheles mosquitoes inhibit gene drive spread under challenging behavioural conditions in large cages

D’Amato, R., Taxiarchi, C., Galardini, M. et al.,  Nature Communications,  15:952. 2024.
CRISPR-based gene drives have the potential to spread within populations and are considered as promising vector control tools. A doublesex-targeting gene drive was able to suppress laboratory Anopheles mosquito populations in small and large cages, and it is considered for field ...

Meiotic drive against chromosome fusions in butterfly hybrids

Jesper Boman, Christer Wiklund, Roger Vila, Niclas Backström,  bioRxiv,  2024.
Species frequently differ in karyotype, but heterokaryotypic individuals may suffer from reduced fitness. Chromosomal rearrangements like fissions and fusions can thus serve as a mechanism for speciation between incipient lineages but their evolution poses a paradox. How does ...
