Flies use taste receptors on their tarsi (feet) to determine if a surface is suitable for feeding, this allows them to quickly assess potential food sources.

1.2. Fly Life Cycle

Understanding the fly life cycle is crucial for effective pest control. Flies undergo complete metamorphosis, which includes four distinct stages:

Egg: Flies lay their eggs in decaying organic matter, garbage, or other suitable substrates.
Larva (Maggot): The eggs hatch into larvae, commonly known as maggots. Maggots feed voraciously, growing rapidly as they molt through several instars.
Pupa: Once the larva is fully grown, it enters the pupa stage. During this stage, the larva develops within a protective casing.
Adult: After the pupa stage, the adult fly emerges. The adult fly is capable of reproduction and continues the cycle.

Impact of Temperature on Life Cycle:

Warm Temperatures: Accelerate the life cycle, leading to faster development and reproduction.
Cold Temperatures: Slow down or halt development, with extreme cold causing mortality, particularly among adult flies.

1.3. Behavior of Flies

Flies exhibit specific behaviors that are influenced by environmental conditions. These behaviors include:

Feeding: Flies are attracted to sources of food and nutrients, particularly decaying matter, sugary substances, and liquids.
Reproduction: Flies reproduce rapidly in warm conditions, laying eggs in suitable substrates such as garbage, manure, or decaying organic matter.
Flight: Flies are capable fliers and can cover significant distances in search of food, mates, or suitable breeding sites.
Resting: Flies often rest on surfaces such as walls, ceilings, vegetation, or structures near food sources or breeding sites.
Aggregation: Flies may aggregate in large numbers under favorable conditions, forming swarms or clusters.

2. Impact of Temperature on Flies

Temperature significantly affects the physiology and behavior of flies. Flies are cold-blooded, meaning their internal body temperature is influenced by the external environment. Extreme temperatures can disrupt their biological processes and lead to death.

2.1. Excessive Heat and Flies

Flies generally thrive in warm conditions because heat boosts their reproduction rates. The ideal temperature range for fly activity and reproduction is between 75°F to 85°F (24°C to 29°C).

2.1.1. Effects of High Temperatures

Increased Reproduction: Warmer temperatures can accelerate the reproductive cycle of flies, leading to a population boom.
Enhanced Activity: Flies become more active and mobile, increasing their feeding and breeding activities.
Dehydration: Excessive heat can lead to dehydration, especially if flies do not have access to water sources.
Reduced Egg Laying: Some studies suggest that extremely high temperatures can reduce the number of eggs laid by female flies.

2.1.2. Coping Mechanisms

Seeking Shade: Flies often seek refuge in shaded areas to avoid direct sunlight and reduce their body temperature.
Increased Water Intake: Flies may increase their water intake to stay hydrated in hot conditions.
Reduced Activity: During the hottest parts of the day, flies may reduce their activity levels to conserve energy and minimize heat exposure.

2.2. Extreme Cold and Flies

Flies struggle to survive in cold weather. As temperatures drop, their metabolic processes slow down, and they become less active.

2.2.1. Effects of Low Temperatures

Reduced Activity: Flies become sluggish and less mobile as temperatures decrease.
Metabolic Slowdown: Their metabolism slows down, reducing their energy consumption but also their ability to function.
Mortality: Adult flies typically die when temperatures drop below a certain threshold.
Dormancy: Some fly species can enter a state of dormancy or hibernation to survive cold conditions.
Egg Survival: Fly eggs can often survive in cold conditions, allowing the population to rebound when warmer weather returns.

2.2.2. Critical Temperatures

Survival Threshold: The temperature at which flies can no longer survive varies depending on the species. Generally, most adult flies die when temperatures consistently drop below 45°F (7°C).
Lethal Temperature: The lethal temperature, at which flies die, is typically below freezing, around 32°F (0°C) or lower. However, prolonged exposure to temperatures just above freezing can also be fatal.

2.3. Overwintering Strategies

To survive the winter, flies employ several strategies:

Dormancy: Some adult flies enter a state of dormancy, seeking shelter in protected locations such as buildings, tree bark, or underground burrows.
Pupae Survival: Many fly species overwinter as pupae, which are more resistant to cold temperatures than adult flies. The pupae remain dormant until warmer weather triggers their development into adults.
Egg Survival: Fly eggs can also survive the winter, particularly if they are laid in protected locations. These eggs hatch in the spring when temperatures rise.

2.4. Research Findings on Temperature Effects

According to research from Embry-Riddle Aeronautical University, studies have shown that temperature plays a crucial role in the distribution and abundance of fly populations. For example, a study published in the Journal of Medical Entomology found that fly activity significantly decreases at temperatures below 50°F (10°C). Additionally, the study noted that certain fly species are more tolerant of cold temperatures than others. These findings highlight the importance of understanding the specific temperature tolerances of different fly species for effective pest management strategies.
