CRISPR gene drive efficiency and resistance rate is highly heritable with no common genetic loci of large effect

Champer, JW, Z. X.; Luthra, A.; Reeves, R.; Chung, J.; Liu, C.; Lee, Y. L.; Liu, J. X.; Yang, E.; Messer, P. W.; Clark, A. G.,  Genetics,  212:333-341. 2019.
Gene drives could allow for control of vector-borne diseases by directly suppressing vector populations or spreading genetic payloads designed to reduce pathogen transmission. Clustered regularly interspaced short palindromic repeat (CRISPR) homing gene drives work by cleaving ...

Gene drive and RNAi technologies: a bio-cultural review of next-generation tools for pest wasp management in New Zealand

S. Palmer, P. K. Dearden, O. R. Mercier, A. King-Hunt and P. J. Lester,  Journal of the Royal Society of New Zealand,  1-18. 2021.
There is a global need for novel, next-generation technologies and techniques to manage pest species. We review work on potential step-changing technologies for large landscape (>1000 hectares) pest management of social Vespula wasps. We also review M?ori perspectives on these ...

Herbicide resistant weeds: A call to integrate conventional agricultural practices, molecular biology knowledge and new technologies

V. E. Perotti, A. S. Larran, V. E. Palmieri, A. K. Martinatto and H. R. Perrningeat,  Plant Science,  290:15. 2019.
Herbicide resistant (HR) weeds are of major concern in modern agriculture. This situation is exacerbated by the massive adoption of herbicide-based technologies along with the overuse of a few active ingredients to control weeds over vast areas year after year. Also, many other ...

Male-biased adult production of the striped fruit fly, Zeugodacus scutellata, by feeding dsRNA fpecific to Transformer-2

M. A. Al Baki, M. Vatanparast and Y. Kim,  Insects,  11:211. 2020.
Sterile insect release technique (SIT) is effective for eradicating quarantine insects including various tephritid fruit flies. When SIT is used for fruit flies, it is challenging to remove females from sterile males due to oviposition-associated piercing damage. This study ...

New Pesticides Will Modify Insect Genes: What Could Go Wrong?

Food Tank,  EcoWatch,  2021.
Farmers across the U.S. could soon fill their pesticide spray tanks with a substance known as interfering RNA (RNAi). (RNA is a molecule similar to DNA.) Insects that are exposed to it — either by eating crops sprayed with the substance or by landing on a crop and absorbing it ...

Persistent Spodoptera frugiperda rhabdovirus infection in Sf9 cells is not restricted by Wolbachia wMelPop-CLA and wAlbB strains and is targeted by the RNAi machinery

R. Parry, H. de Malmanche and S. Asgari,  Virology,  563:82-87. 2021.
The endosymbiotic bacterium Wolbachia pipientis confers RNA virus refractoriness in Drosophila and Aedes mosquitoes. Questions remain about the Wolbachia-virus restriction phenotype and how extensive this phenomenon may be within other arthropods. Here, we generated two ...

RNAi-based products: A sustainable alternative to hazardous pesticides

Ghent University,  Phys Org,  2021.
RNAi-based biocontrol is a great alternative to hazardous pesticides and can contribute towards reversing the alarming decline in farmland birds and beneficial insects (especially pollinating ones). RNAi is a well-known natural biological process in most

RNAi: Applications in Vertebrate Pest Management

K. E. Horak,  Trends in Biotechnology,  38:1200-1202. 2020.
the development of novel control technologies must be focused on species specificity and low environmental impact. Sequence-specific gene silencing via RNAi holds promise for effective management of pest wildlife.

The Antiviral Small-Interfering RNA Pathway Induces Zika Virus Resistance in Transgenic Aedes aegypti

A. E. Williams, I. Sanchez-Vargas, W. R. Reid, J. Y. Lin, A. W. E. Franz and K. E. Olson,  Viruses,  12:18. 2020.
We used CRISPR/Cas9 to re-target a previously characterized locus (Chr2:321382225) and engineered mosquitoes expressing an inverted repeat (IR) dsRNA against the NS3/4A region of the ZIKV genome. Small RNA analysis revealed that the IR effector triggered the mosquito's siRNA ...
