Gene Editing Screwworms and Blowflies

Paolo et al. report the first successful use of CRISPR/Cas9 in the New World Screwworm fly, Cochliomyia hominivorax (C. hominivorax), a parasite of warm blooded animals including humans, as well as a CRISPR/Cas9 protocol for the Australian sheep blowfly, Lucilia […]

CRISPR/Cas9-Mediated NHEJ Mutations in Anastrepha suspensa Paves Way for HDR

In an a recent experiment published in Gene, Li and Handler (2019) utilized readily available study systems and newly emerging genetic technologies and demonstrated both germline and somatic CRISPR/Cas9 induced mutations in Anastrepha ludens. The creation of heritable mutations was […]

Recreating tra-2 Alleles in D. suzukii

Li and Handler (2017) have recently reported using CRISPR/Cas9 to make a temperature-sensitive transformer-2 (tra-2) allele in the pest species Drosophila suzukii by mutating the nucleotides orthologous to the Drosophila melanogaster tra-2ts2 allele. This study demonstrates an important proof of […]

Transgenic TALEN Expression to Control Sex in Bombyx

Analysis of gene function in insects by editing the genome, or reverse genetics, is now greatly facilitated thanks to powerful genetic technologies, such as TALENs, ZFNs, and more recently CRISPR/Cas9, becoming available in many organisms. However, screening of transgenic mutated […]
