The paper “Highly efficient temperature inducible CRISPR-Cas9 gene targeting in Drosophila suzukii”, is now published in the International Journal of Molecular Sciences. In this effort, Ying Yan and colleagues developed the first conditional CRISPR/Cas9 system in insect species that allows temperature-controllable gene targeting. Our master student, Ms. Yukino Kobayashi, who dedicated her master thesis to the characterization of the system, is the second author of this paper. 

 

2021-06  |  Publication in Scientific Reports: the early female-killing system in D. suzukii 

The paper “A transgenic female killing system for the genetic control of Drosophila suzukii”, is now published in Scientific Reports. In this research, one of the first female-killing systems in the global pest Drosophila suzukii was developed, which can facilitate the genetic control of this species.  

 

2021-02 | Book on "Area-Wide Integrated Pest Management published by Tayler-Francis/CRC

 

This new book addresses various fundamental components of AW-IPM. It is a great collection of chapters from 184 experts from more than 31 countries and includes many technological advances in the areas of genetics, molecular biology, microbiology, resistance management, and social sciences that facilitate the planning and implementing of area-wide strategies. Our chapter on Genome Editing and its Applications for Insect Pest Control summarizes the potential of novel technologies and discusses if they are a 'curse of blessing' for the insect pest control field.

 

2021-01 | 2nd edition of the Sterile Insect Technique” book published by Tayler-Francis/CRC

 The second edition of the "bible" on the Sterile Insect Technique has been published that updated and considerably expanded the content of the first edition from 2005. A great variety of subjects of the SIT is covered, from the history to improved prospects for its future application. The major chapters discuss the principles and technical components of applying sterile insects. Other chapters deal with supportive technologies, economic, management, and environmental considerations, and the socio-economic impact of AW-IPM programs that integrate the SIT. In addition, this second edition includes six new chapters covering the latest technologies in this field. Read more on one of those chapters about Applying Modern Molecular Technologies in Support of the Sterile Insect Technique by Irina Häcker, Kostas Bourtzis and Marc F. Schetelig.

 

2021-01  |  Publication in Nature Communications: the white pupae gene.

2020-10  |  Men only! .... publication in Scientific Reports

Congratulations Rosi for the new publication in Scientific Reports! Efficient SIT programs require the release of a male-only population. Economically the best way to get that is by transforming female embryos into male adults. How’s that possible? We showed it, using CRISPR/Cas9 HDR site-specific mutagenesis on the transformer 2 gene. Check out more here!

2020-04  |  First SINO-German collaboration meeting

The first joint video meeting with the Agricultural Genomics Institute of the Chinese Academy of Agricultural Sciences (CAAS) was held online under the framework of the “SINO-German Mobility Program” (DFG-NSFC, Germany-China, 2020-2022). Both sides introduced their teams, research plans and discussed the roadmap for future collaboration. We’ll continue the information exchange, project planning, and joint publication efforts, despite the hurdles of the COVID pandemic. 

The “SINO-German Mobility Program” which facilitates bilateral cooperation between top research groups from China and Germany, was awarded in Nov. 2019 to us by the DFG-NSFC (2020-2022). In this program, we will collaborate with the Agricultural Genomics Institute at the Chinese Academy of Agricultural Sciences (AGIS-CAAS, China) under the topic “Development of Next-Generation Control Strategies for Important Invasive Species Based on Metagenomic Analysis”. AGIS-CAAS is one of the leading institutes in the world that address genome research in economically important agricultural species. Combining our expertise in modern molecular techniques, sequencing tools, and bioinformatical analysis, this program aims for a better understanding of the biological invasion and provide better solutions for the agricultural landscape in both China and Germany.

2019-06  |  Aktionstag "Insekten (er)leben" - Es kreucht und fleucht

Gießen. Wetterauer Zeitung, 2019

"Zucker reicht. Mehr brauchen die Männchen nicht zum Leben. Ihre Weibchen sind deutlich anspruchsvoller. Es geht, na klar, um Mücken. Genauer: um die in den Tropen und Subtropen heimischen Gelbfiebermücken. Als Prof. Marc Schetelig am Samstag im Interdisziplinären Forschungszentrum (IFZ) der JLU über seine Forschungsobjekte spricht, wirken sie einen Moment lang relativ menschlich. In Wahrheit sind sie am Aktionstag »Insekten (er)leben« der Institute für Insektenbiotechnologie und Tierökologie ein Beispiel für Insekten als Gesundheitsrisiko. Ob Dengue, Zika oder andere Viren: Die Weibchen saugen nicht nur Blut - sie übertragen auch Krankheiten. Die in seinem Kasten seien aber virenfrei, verspricht Schetelig. Falls eine ausbüxt....."
