To fight berry-busting fruit flies, researchers focus on sterilizing the bugsM. Walling, KTAL News.com, 2023.
Paul Nelson is used to doing battle with an invasive fruit fly called the spotted wing drosophila, a pest that one year ruined more than half the berries on the Minnesota farm he and his team run. In recent years, they’ve cut their losses closer to 5%, but it’s been ... |

CRISPR/Cas9-based gene drive could suppress agricultural pestsNorth Carolina State University, Phys Org, 2023.
Researchers have developed a "homing gene drive system" based on CRISPR/Cas9 that could be used to suppress populations of Drosophila suzukii vinegar flies—so-called "spotted-wing Drosophila" that devastate soft-skinned fruit in North America, Europe and parts of South ... |

Assessing the hybridization potential between a hypothetical gene drive-modified Drosophila suzukii strain and non-target Drosophila speciesJ. Romeis, S. Wolf, J. Collatz, J. Enkerli and F. Widmer, IOBC-WPRS Bulletin, 163:108. 2023.
Genetically engineered gene drives (GD) are a potentially powerful tool to control pest insects by population suppression or even elimination. Before living GD modified insects can be released into the environment, they must pass an environmental risk assessment (ERA). A key ... |

Modeling-informed Engineered Genetic Incompatibility strategies to overcome resistance in the invasive Drosophila suzukiiA. Sychla, N. R. Feltman, W. D. Hutchison and M. J. Smanski, Frontiers in Insect Science, 2. 2022.
Engineered Genetic Incompatibility (EGI) is an engineered extreme underdominance genetic system wherein hybrid animals are not viable, functioning as a synthetic speciation event. There are several strategies in which EGI could be leveraged for genetic biocontrol of pest ... |

CRISPR, an eco-friendly technology, may detect crop pestsW. Adam, list23, 2022.
Drosophila suzukii, an invading insect pest, is a threat to agricultural yields, especially to the production of fruits such as strawberries, cherries, plums, and grapes in western countries. Until now, control measures to stop the spread of D. suzukii have been inadequate. A ... |

Precision Guided Sterile Males Suppress Populations of an Invasive Crop PestN. P. Kandul, J. Liu, A. Buchman, I. C. Shriner, R. M. Corder, N. Warsinger-Pepe, T. Yang, A. K. Yadav, M. J. Scott, J. M. Marshall and O. S. Akbari, GEN Biotechnology, 1:372-385. 2022.
The Drosophila suzukii invasion of western countries has created an immense agricultural and economic threat to crop production. Despite many attempts to suppress its population, D. suzukii continues to destroy soft-flesh fruits. Precision guided sterile insect technique (pgSIT) ... |

Field Suppression of Spotted Wing Drosophila (SWD) (Drosophila suzukii Matsumura) Using the Sterile Insect Technique (SIT)R. A. Homem, Z. Mateos-Fierro, R. Jones, D. Gilbert, A. R. McKemey, G. Slade and M. T. Fountain, Insects, 13. 2022.
Drosophila suzukii (spotted wing drosophila—SWD) is an economically important pest of soft and stone fruit worldwide. Control relies on broad-spectrum insecticides, which are neither fully effective nor environmentally sustainable. The sterile insect technique (SIT) is a ... |

Evaluation of Additional Drosophila suzukii Male-Only Strains Generated Through Remobilization of an FL19 TransgeneA. Yamamoto, A. K. Yadav and M. J. Scott, Frontiers in Bioengineering and Biotechnology, 10. 2022.
Drosophila suzukii (D. suzukii) (Matsumura, 1931; Diptera: Drosophilidae), also known as spotted wing Drosophila, is a worldwide pest of fruits with soft skins such as blueberries and cherries. Originally from Asia, D. suzukii is now present in the Americas and Europe and has ... |

Stakeholder engagement to inform the risk assessment and governance of gene drive technology to manage spotted-wing drosophilaA. E. Kokotovich, S. K. Barnhill-Dilling, J. E. Elsensohn, R. Li, J. A. Delborne and H. Burrack, Journal of Environmental Management, 307:114480. 2022.
Emerging biotechnologies, such as gene drive technology, are increasingly being proposed to manage a variety of pests and invasive species. As one method of genetic biocontrol, gene drive technology is currently being developed to manage the invasive agricultural pest ... |

Ecological vulnerability analysis for suppression of Drosophila suzukii by gene drivesC. R. Lalyer, L. Sigsgaard and B. Giese, Global Ecology and Conservation, 32:e01883. 2021.
Synthetic gene drives are transgenic constructs that aim to bias heredity and thereby influence the characteristics and fate of populations regarding abundance and evolution. Aside from irreversible effects in ecosystems that could be triggered by the release of a gene drive, ... |

Pest reduction with female killers and sterile malesL. Mertz, Good Fruit Grower, 2021.
New ways to fight spotted wing drosophila are in the works, thanks to new genetic engineering tools. These transgenic methods introduce new reproduction-hampering genes into male SWD, so that when they mate with females, the females either don’t have any young, or their female ... |
