Revised Arthropod Containment Guideline

The  “Arthropod Containment Guidelines” developed by The American Committee of Medical Entomology, a Committee within the American Society of Tropical Medicine and Hygiene have been revised and published in Vector-Borne and Zoonotic Diseaese. The ACGs were originally published in 2004 […]

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 […]

Improved Honeybee Germline Transformation

Otte et al (2018) build upon their previous work (Schulte et al. 2014) in this new publication and demonstrate a twofold improved efficiency at generating transgenic honeybees using the piggyBac transposon system.  The inability to generate high transformation rates has […]

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 […]

Cas9 Orthologs with Minimal PAM Requirements

In their recent paper Chatterjee and colleagues (2018) describe a natural protospacer adjacent motif (PAM) plasticity of previously uncharacterized Cas9 endonuclease from Streptococcus canis (ScCas9).  Chatterjee et al (2018) report ScCas9’s affinity to minimal 5’-NNG-3’ PAM sequences and describe its accurate editing capabilities, […]

Precision-Guided Sterile Insect Technique

Right after the 2019 New Year, Kandul et al (2019) described a novel CRISPR-based technology which they termed as “precision guided sterile insect technique (pgSIT)”. The idea of traditional SIT was planted in 1930s, which uses radiation to induce sterility […]
