Manure composting reduces house fly population.

Area of Science:

• Agricultural Science
• Entomology
• Environmental Science

Background:

• House flies (Musca domestica L.) are significant pests in agricultural settings.
• Manure management is crucial for controlling house fly breeding sites.
• Organic manures, particularly poultry litter, are known attractants for house flies.

Purpose of the Study:

• To evaluate the impact of manure composting duration on house fly populations.
• To determine if composting reduces the attractiveness of manures to house flies for breeding.
• To establish the relationship between composting period and house fly reduction.

Main Methods:

• Three field experiments were conducted at the University of Jordan.
• Manures were composted for varying durations: 0, 2, 4, and 6 weeks.
• House fly populations were monitored in relation to composted manure types and durations.

Main Results:

• House flies showed a strong preference for broiler and layer manures for breeding.
• Increasing composting periods significantly reduced house fly populations.
• A linear correlation was observed between the composting duration and the reduction in house flies.

Conclusions:

• Composting organic manures, especially for extended periods, is an effective strategy for house fly control.
• While broiler and layer manures remain attractive, longer composting periods mitigate their suitability for breeding.
• Integrated pest management strategies should consider manure composting duration for effective house fly population reduction.
