“This discovery is a true milestone. After more than 35 years of research, we now have a precise molecular handle on temperature-sensitive lethality,” said Kostas Bourtzis, a molecular biologist in the Joint Centre’s Insect Pest Control Section and co-author of the study. “This opens up the possibility of expanding genetic sexing systems to a wide range of insect pests with agricultural, veterinary and medical relevance — a major advancement for SIT programmes globally.”
“With the identification of the tsl gene, we are closing a major knowledge gap that has long hindered the application of genetic sexing beyond the Mediterranean fruit fly,” said Marc F. Schetelig, professor of insect biotechnology in plant protection at JLU and liaison officer at the newly established Liebig Centre for Agroecology and Climate Impact Research, also a co-author of the study. “This paves the way for highly specific and sustainable insect control strategies without the use of chemical insecticides.”
The study exemplifies the longstanding close strategic partnership between JLU and the Joint FAO/IAEA Centre. With recent designation of the Liebig Centre for Agroecology and Climate Impact Research as an IAEA Collaborating Centre in May 2025, this collaboration has been institutionalized, enabling the joint development of biotechnology tools for sustainable insect pest control on a global scale.
