Slide 3: Bio-Gene's Technology Platform
Bio-Gene’s Technology Platform Bio-Gene is developing two products for key insect control markets Qcide® - tasmanone Flavocide® - flavesone Natural Product Nature Identical Compound Extracted from the leaves of a chemotype of Proprietary chemical process to synthesise the beta- Eucalyptus cloeziana
Slide 4: Importance of novel mode of action in mosquito control
IIMPORTANCE OF NOVEL MODE OF ACTION IN MOSQUITO CONTROL ❖ Insecticide resistance is a significant challenge in all markets where insecticides are used. ❖ Adult mosquito control is heavily dependent on very few chemical classes, in particular synthetic pyrethroids. ❖ Resistance to these products unde
Slide 5: Flavesone novel mode of action
FLAVESONE NOVEL MODE OF ACTION Bio-Gene has completed studies which confirm the definitive target site of β-triketone compounds in insects. These results provide critical Electrophysiological testing on insect information that creates validation data to support a “new class of (Drosophila) DRG neuro
Slide 6: Laboratory and field efficacy studies against mosquitoes
Multiple laboratory and field efficacy studies contracted by Bio-Gene demonstrate activity of Flavocide and Qcide against mosquitoes Flavocide and Qcide have been tested via contract research with: , Sydney, Australia West Lafayette, IN, USA Efficacy results vs. mosquito species confirm activity of
Slide 7: Laboratory evaluations at University of Technology Sydney
