“Sexing” Technologies – A Review

In a recent review,  Lutrat et al. (2019) provide a comprehensive summary of current (since 2003) sexing methods available for various dipteran pest species. The review distinguishes between early and late acting sexing methods and elaborates on the techniques used […]

Heritable Gene Editing in Thermobia domestica

Ohde et al report the first successful development and use of CRISPR/Cas9 in the basally branching insect Thermobia domestica. By co-injecting Cas9 nuclease with sgRNA targeting a T. domestica ortholog of the Drosophila melanogaster white gene (Td-w), the authors created […]

2019 IGTRCN Technical Short Course – Applications Open

2019 IGTRCN Technical Short Course on Insect Genetic Technologies: Theory and Practice July 21 – 26, 2019 The Insect Transformation Facility Institute for Bioscience and Biotechnology Research University of Maryland College Park Applications by April 1, 2019 (24 seats available) […]

Enhancer Trapping in Mosquitoes

A recent manuscript published on Genes Genomes Genetics by Reid et al (2018) reports an exciting improvement to piggyBac-based promoter-trap designed in Anopheles stephensi. The development of this new piggyBac-based promoter-trap designs provides further knowledge and exciting venues to examine […]

Microinjection of the Sand Fly Lutzomyia longipalpis, a Vector for Leishmaniasis

Two recent papers, Jefferies et al (2018) and Martin-Martin et. al (2018), describe experiments to develop and optimise a sand fly microinjection protocol. There are 2 authors to this post: Alla Madich, Simon Collier, technical constraints on this website allow […]

One-step recombination-mediated cassette exchange (RMCE) in Drosophila suzukii

Schetelig et al. (2018) describe a relatively efficient recombinase-mediated cassette exchange (RMCE) system for engineering the recently sequenced genome (Chiu et al., 2013) of the spotted wing drosophila, Drosophila suzukii, which is a significant pest of small and stone fruits. […]

Whole-brain, Single Cell Activity Mapping in Transgenic Gryllus

Watanabe et al in eNeuro (2018) report their successful development of transgenic cricket Gryllus bimaculatus that bears a transcriptional reporter for whole-brain, single cell-resolution activity mapping. In order to construct a transcriptional reporter for activity mapping, it is critical to […]

ReMOT control delivery technology holds promise for CRISPR-Cas9 activity independent of embryonic injection

A new report in Nature Communications by Chaverra-Rodriguez et al. details a novel Cas9-delivery approach for insect genetic modification. In their work, Chaverra-Rodriguez et al introduce a technology they term “ReMOT control”, or Receptor-Mediated Ovary Transduction of Cargo. In their […]

Gene Drives and the Potential Benefits of CRISPR Technology

Marshall and Akbari review a range of different proposed gene drive systems and discuss ways in which CRISPR may be useful in engineering them in a recent issue of ACS Chemical Biology. In the years since translocations were first suggested […]
