Insecticide Optimized for Autodissemination Use

The US Navy seeks a partner to license and commercialize pyriproxyfen formulations that improve transportability and deposition at the insect nesting site even in locations with high heat and relative humidity

The Technology: 

The US Navy Entomology Center of Excellence (NECE) has developed dry powder and liquid formulations of pyriproxyfen that can easily be acquired by adult insects in autodissemination devices and readily transported back to nesting habitats where it effectively prevents immature insects from developing into reproductive adulthood. The NECE formulations are heat stable, easy to establish and maintain in an emulsion, and attach well to target insects. The key is a fine powder formulation that doesn’t clump over time, is stable in areas of high heat and high relative humidity, and still dissolves well in aqueous solutions.

Autodissemination relies on targeted insects to carry an insecticide back to their nesting site where the active ingredient is further distributed to interrupt the maturation of larvae. The US Navy’s formulations attach well to insects and are resistant to loss during insect flight and grooming, but do not trap the adults nor adhere so tightly as to prevent deposition at the nesting site. Both forms are resistant to crystallization and do not attract ants.

Benefits: 
  • High Performance: Fine powder active ingredient particles adhere to adults without becoming a sticky trap, maintain adherence during flight and grooming, but are still dislodged in the nesting area to affect immature insects
  • Stable: Liquid and dry powder formulations are designed to maintain flowability and efficacy in high heat and high relative humidity environments
  • Manufacturable: Formulations are based on commercially available materials and common manufacturing techniques
The Opportunity: 
  • A pending US patent application is available for license
  • Potential for collaboration with Navy Entomology Center of Excellence researchers
