Effective Control of Poultry Red Mite (Dermanyssus gallinae) Infestations Using Fluralaner (EXOVET)

Introduction:

Poultry red mite (PRM), Dermanyssus gallinae, is a significant ectoparasite affecting poultry production globally, including MENA region . Its impact on animal welfare, productivity, and economic viability is substantial, resulting in decreased egg production, reduced feed conversion, anemia, and increased susceptibility to secondary infections. Effective control strategies are crucial for maintaining flock health and optimizing farm profitability. This article focuses on the application of fluralaner (EXOVET), a novel acaricide, for the management of PRM infestations in poultry, drawing upon current scientific understanding and practical applications.

The Challenge of Poultry Red Mite Infestations:

PRM is a nocturnal hematophagous mite that inflicts significant stress on poultry, leading to behavioral changes such as excessive preening and restlessness. The mite’s rapid life cycle and ability to survive in various environmental conditions contribute to its persistent presence in poultry farms. Traditional control methods, including environmental treatments and topical acaricides, often prove insufficient due to challenges in reaching all mite hiding places and the development of acaricide resistance. Furthermore, the transmission of pathogens such as E. coli, Pasteurella multocida, and avian influenza by PRM amplifies the economic burden.

Fluralaner (EXOVET): A Novel Approach to PRM Control:

Fluralaner, the active ingredient in EXOVET, is a systemic acaricide that offers a targeted and effective approach to PRM control. It acts by inhibiting the arthropod nervous system, leading to rapid paralysis and death of mites that ingest it. This mechanism of action provides several advantages:

• Systemic Efficacy: Fluralaner is administered via drinking water, ensuring that all birds receive the treatment, regardless of individual variations in behavior or access to topical applications.
• Prolonged Activity: Fluralaner exhibits prolonged activity, effectively breaking the mite life cycle by killing both adult mites and preventing egg production for an extended period.
• Reduced Environmental Contamination: Compared to environmental sprays, fluralaner minimizes the risk of environmental contamination and reduces exposure to farm personnel.
• Targeted Action: Fluralaner’s systemic action targets mites feeding on the birds, minimizing impact on beneficial insects and other non-target organisms.

Application and Treatment Protocol:

EXOVET is administered at a dosage of 0.5 mg fluralaner per kg body weight, given twice, seven days apart, via drinking water. It is crucial to ensure that the medicated water is the sole source of drinking water during the treatment period. This protocol ensures thorough exposure and effective elimination of the mite population.

Integrated Pest Management (IPM) and Biosecurity:

While fluralaner provides a potent tool for PRM control, it should be integrated into a comprehensive IPM strategy. This includes:

• Biosecurity Measures: Strict biosecurity protocols, such as quarantine of new birds, restricted access to poultry houses, and disinfection of equipment, are essential to prevent mite introduction and spread.
• Environmental Hygiene: Regular cleaning and disinfection of poultry houses, removal of litter, and maintenance of dry conditions can minimize mite survival and reproduction.
• Monitoring and Early Detection: Regular inspection of birds and poultry houses for signs of mite infestation is crucial for early intervention.
• Resistance Management: Responsible use of acaricides, including fluralaner, is essential to prevent the development of resistance. Adhering to recommended dosages and treatment protocols is critical.

Benefits of Fluralaner (EXOVET) Use:

• Improved flock health and welfare.
• Increased egg production and feed conversion efficiency.
• Reduced risk of secondary infections and disease transmission.
• Minimized environmental contamination.
• Enhanced farm profitability.

Conclusion:

Fluralaner (EXOVET) represents a significant advancement in the control of poultry red mite infestations. Its systemic action, prolonged efficacy, and reduced environmental impact make it a valuable tool for poultry farmers. However, it is essential to integrate fluralaner into a comprehensive IPM strategy that includes biosecurity measures, environmental hygiene, and responsible acaricide use. By adopting a holistic approach, poultry farmers can effectively manage PRM infestations, safeguard flock health, and ensure sustainable production.
