Fine-scale estimation of key life-history parameters of malaria vectors: implications for next-generation vector control technologiesA. L. Morris, A. Ghani and N. Ferguson, Parasites and Vectors, 14:311. 2021.
Mosquito control has the potential to significantly reduce malaria burden on a region, but to influence public health policy must also show cost-effectiveness. Gaps in our knowledge of mosquito population dynamics mean that mathematical modelling of vector control interventions ... |

Ecological Relationships of Mosquito Disease Vectors: Anticipating Risk Assessment of Gene Drive TechnologiesStephanie James, Hector Quemada and David O'Brochta, GeneConvene Global Collaborative, 2021.
An often-raised concern for the development of genetically modified mosquito technologies, particularly those involving gene drive, as tools to prevent disease transmission is the limitation of our understanding of the roles these species may play within the ecosystem. This ... |

Mosquito Sexual Selection and Reproductive Control ProgramsL. J. Cator, C. A. S. Wyer and L. C. Harrington, Trends in Parasitology, 37:330-339. 2021.
The field of mosquito mating biology has experienced a considerable expansion in the past decade. Recent work has generated many key insights about specific aspects of mating behavior and physiology. Here, we synthesize these findings and classify swarming mosquito systems as ... |

Polyandry blocks gene drive in a wild house mouse populationA. Manser, B. Konig and A. K. Lindholm, Nature Communications, 11:8. 2020.
Here, we study the impact of polyandry on a well-known gene drive, called t haplotype, in an intensively monitored population of wild house mice. First, we show that house mice are highly polyandrous: 47% of 682 litters were sired by more than one male. Second, we find that ... |
