Genetically engineered insects with sex-selection and genetic incompatibility enable population suppression [PDF]

eLife, 2022
Engineered Genetic Incompatibility (EGI) is a method to create species-like barriers to sexual reproduction. It has applications in pest control that mimic Sterile Insect Technique when only EGI males are released.

Stability analysis in a mosquito population suppression model [PDF]

Journal of Biological Dynamics, 2020
In this work, we study a non-autonomous differential equation model for the interaction of wild and sterile mosquitoes. Suppose that the number of sterile mosquitoes released in the field is a given nonnegative continuous function.

Evolution of male-killer suppression in a natural population. [PDF]

PLoS Biology, 2006
Male-killing bacteria are widespread in arthropods, and can profoundly alter the reproductive biology of their host species. Here we detail the first case of complete suppression of a male killer.

Genetic Control of Mosquitoes: population suppression strategies [PDF]

Revista do Instituto de Medicina Tropical de São Paulo, 2012
Over the last two decades, morbidity and mortality from malaria and dengue fever among other pathogens are an increasing Public Health problem. The increase in the geographic distribution of vectors is accompanied by the emergence of viruses and diseases

Antiviral Effectors and Gene Drive Strategies for Mosquito Population Suppression or Replacement to Mitigate Arbovirus Transmission by Aedes aegypti [PDF]

Insects, 2020
The mosquito vector Aedes aegypti transmits arthropod-borne viruses (arboviruses) of medical importance, including Zika, dengue, and yellow fever viruses.

Population suppression with dominant female-lethal alleles is boosted by homing gene drive [PDF]

BMC Biology
Background Methods to suppress pest insect populations using genetic constructs and repeated releases of male homozygotes have recently been shown to be an attractive alternative to older sterile insect techniques based on radiation.

Gene drive-based population suppression in the malaria vector Anopheles stephensi [PDF]

Nature Communications
Gene drives are alleles that can bias the inheritance of specific traits in target populations for the purpose of modification or suppression. Here, we construct a homing suppression drive in the major urban malaria vector Anopheles stephensi targeting ...

Challenges in Achieving Viral Suppression Among Adolescents and Young Adults Under a Dolutegravir-Based Regimen: Living with HIV in Gabon [PDF]

Pathogens
Background: Children, adolescents and young adults living with HIV represent a vulnerable population. Achieving viral suppression in this population remains a major challenge in sub-Saharan Africa.

Viral suppression status and associated factors among key populations on ART in Western Oromia, Ethiopia: a retrospective analysis [PDF]

AIDS Research and Therapy
Background Viral suppression, the key goal of antiretroviral therapy (ART) for improving health and preventing transmission, remains understudied among key populations (KPs) in Ethiopia.

Population Suppression in Support of the Sterile Insect Technique [PDF]

, 2021
Suppression or eradication of insect pest populations by the release of sterile insects is often dependent on supplementary methods of pest reduction to levels where the target pest population can be overflooded with sterile insects. Population suppression activities often take place in advance of, or coincide with, the production and release of ...
