Postdoctoral position in Panama on screwworm male-only strains

A postdoctoral position is available immediately to develop transgenic male-only strains of NWS that carry a conditional early-acting female-lethal genetic system. The position is with COPEG and is collaboration with our lab and the USDA. See the Positions page for … Continue reading

Publications on blow fly male-only strains and olfaction

As we continue to optimize genetic systems for male-only strains, we recently reported that selecting driver and effector transgenes with moderate levels of expression could be an effective strategy to obtain strains with good productivity. Ying Yan was first author … Continue reading

Self-Limiting Gene Drive Published

Our paper on a simple killer-rescue gene drive has been published in the Proceedings of the Royal Society B. The experimental was done by Sophia Webster, a former PhD student in the lab and the modeling by Michael Vella, a … Continue reading

Genetic Variation and Potential for Resistance to the tTA Overexpression Lethal System Published

We previously developed a female-specific tTA overexpression system for L. cuprina and C. hominivorax. We found that in some lines females with one copy of the transgene showed high survival but all females died with two copies. This suggested that … Continue reading

Improved Lucilia cuprina sexing strains published

We describe improved transgenic embryonic sexing strains for the Australian sheep blowfly in a recent article in Molecular Genetics and Genomics . We found that promoters from the L. cuprina nullo or Cochliomyia macellaria CG14427 genes drove high levels of tTA expression in the … Continue reading

CRISPR in blowflies published

Our paper on gene editing in screwworm and blowflies has been published in G3. We describe our efforts to optimize CRISPR/Cas9-based gene editing through targeting the brown body gene, which is an ortholog of Drosophila yellow. We then use the … Continue reading
