Mode of Action: The primary target of action of COMFORTIS in insects is an activation of nicotinic acetylcholine receptors (nAChRs). The answer to the question about poultry mites and spinosad is that the provided text does not directly address the use of spinosad for poultry mites.
- The mode of action of spinosad is described for insects, but it does not specifically mention poultry mites.
- The text does not provide information on the effectiveness or safety of spinosad for use in poultry mites 1.
From the Research
Spinosad is not the most effective treatment for poultry mites, as it has been shown to be less sensitive to spinosad compared to other acaricides such as fluralaner 2.
Treatment Options
When considering treatment options for poultry mites, it's essential to choose the most effective and safe method.
- Fluralaner has been shown to be highly effective against northern fowl mites, with an LC50 value of 2.95 ppm 2.
- Spinosad, on the other hand, has an LC50 value of 1587 ppm, indicating lower sensitivity to this acaricide 2.
Application and Safety
For comprehensive mite control, it's crucial to combine treatment with thorough coop cleaning, dust bath provision with diatomaceous earth, and regular monitoring of the flock for signs of reinfestation.
- Always follow the specific product label instructions for concentration and withdrawal periods if collecting eggs for consumption.
- Spinosad works by attacking the nervous system of mites while having low toxicity to birds and mammals, but its effectiveness against poultry mites is limited 2, 3.
Alternative Treatments
Considering the limited effectiveness of spinosad, alternative treatments such as fluralaner may be more suitable for controlling poultry mite infestations.
- Fluralaner has been shown to be highly effective against northern fowl mites, making it a potential alternative to spinosad 2.
