Key Takeaways
- A new technology called BenPol enhances the effectiveness of chemical-free flystrike treatments in sheep.
- Double-stranded RNA (dsRNA) has been improved by BenPol, which protects it from degradation until ingestion by larvae.
- The research aims to transition BenPol from laboratory tests to field trials, with potential applications against other livestock pests.
Innovative Technology to Combat Flystrike in Sheep
Researchers from the University of Queensland have announced a breakthrough in the fight against flystrike, a significant concern for Australia’s wool industry. The newly developed technology, named BenPol, offers a chemical-free method to combat flystrike caused by the infestation of maggots on sheep. This issue currently leads to an annual expenditure of nearly $320 million on chemical pesticides.
Dr. Karishma Mody, a research fellow at the Queensland Alliance for Agriculture and Food Innovation (QAAFI), explained that flystrike is a prevalent problem in Australia that necessitates alternative treatments. Previous studies indicated that double-stranded RNA (dsRNA) could slow larval development and even cause death; however, its efficacy was diminished due to its rapid breakdown in biological fluids.
BenPol acts as a protective capsule for dsRNA, maintaining its integrity long enough for larvae to consume it. This allows the dsRNA to reach the gut and effectively switch off essential genes. Yakun Yan, a PhD candidate at QAAFI, noted that this advancement provides a significant platform for the application of RNA technology in livestock protection.
The success of BenPol was made possible through collaboration with the Department of Primary Industries (DPI), which provided blowfly eggs and larvae for testing. Laboratory experiments proved the technology’s potential, prompting researchers to prepare for the next pivotal phase—field trials involving sheep. Dr. Mody emphasized the importance of industry partnerships in refining BenPol for practical applications on farms.
Moreover, the technology holds promise beyond sheep, with potential applications against other agricultural pests, including cattle ticks and buffalo fly. This innovative leap positions Australia to find environmentally friendly solutions crucial for the sustainability of its wool industry, which accounts for a significant portion of the world’s greasy wool production.
The findings of this research have been published in the journal Pest Management Science, marking a hopeful step toward the future of pest management in livestock.
