How do insects such as flies distinguish suitable places to lay eggs?

Flies have a very rich and sensitive sensory organ, and are able to perceive their surroundings acutely, so as to choose the most suitable place to lay eggs. The larvae of flies like to eat rotten food, so the mother of the fly chooses to lay eggs in the place where the rotten food is kept.

Insects such as flies have very rich and sensitive sensory organs, and can keenly perceive their surroundings, so as to choose the most suitable place to lay eggs. And the larvae of flies like to eat rotten food, so the mother will choose to lay eggs on rotten food.

Because insects such as flies have a very sensitive sense of smell, they can smell a suitable place to lay eggs, and then lay eggs, and after a while, the eggs will hatch naturally.

They have very rich and sensitive organs, and they can detect where they are suitable to survive, and they will make a home in that place.

Other insects, such as flies, have a very rich body surface with sensory organs, and they can keenly sense the temperature and humidity of their surroundings and choose the most suitable place to lay their eggs.

Insects usually lay their eggs very close to food. Ensuring that the offspring will have access to food as soon as they are born. Therefore, insects will give preference to places with a lot of food to lay eggs.

Golden yellow, a little smaller than sesame seeds, are fly eggs.

Banana-shaped or oval-shaped, about 1 mm long, with two crests on the dorsal surface of the egg shell, the thinnest membrane between the crests, from which the larvae emerge when hatching.

The peak of spawning is at 17:00 to 19:00 every day.

The length of the pre-oviposition period (i.e. the time from emergence, to the first oviposition) of female flies is closely related to the ambient temperature: an average of 9 days at 15, only a few days at 35, and no eggs at 15 or less. After mating, female flies often crawl into the breeding crevices such as human and animal feces, and extend out of the ovipositor tube to lay eggs in the depths of the breeding organisms, so that the eggs can be fully protected by the silver jujube.

Development:

The development time of the egg is 8 24 hours, which is related to the ambient temperature and humidity, and the egg does not develop under the 13 or 13 holes, and dies if it is lower than 8 or higher than 42.

The incubation time of eggs decreases with increasing temperature in the following ranges: 22 hours, 20 hours; 25 hours, 16-18 hours; 28 hours, 14 hours; 35 hours, only 8-10 hours. The humidity of the growing substrate also has an effect on the hatchability of the eggs:

When the relative humidity is 75% and 80%, the hatching rate is the highest. Hatchability is significantly reduced below 65% or above 85%.

This is the eggs laid by flies, food that has been contaminated, it is better not to eat it, it is recommended to discard it directly.

The eggs are generally milky white, banana-shaped or oval-shaped, about 1 mm long, and have two crests on the back of the egg shell, with the thinnest membrane between the crests, from which the larvae emerge from the limbs when hatching. Male houseflies can be sexually mature and mate 18 to 24 hours after emerging, and females can mate 30 hours after eclosion. The mating time is generally at 5 a.m

Sensitive sense of smell, extrasexual hormones and vision are all important factors to promote the mating of male and female flies. The development time of the egg is 8 24 hours, which is related to the environmental temperature and humidity, and the egg does not develop when it is below 13, and dies if it is lower than 8 or higher than 42.

Precautions for eating food that has been bitten by flies

Flies often land on disgusting things, spoiled food, feces, etc. are their favorites, and they will naturally be contaminated with bacteria. Studies have found that there are about 200 types of harmful bacteria on each fly. They don't need to stay on their food for long, and with a little touch, they'll leave these terrible things behind.

The taste receptors of flies are on the feet, and they often rub their feet because they are contaminated with a lot of dirt that affects their sense of taste. It may not sound like much, but flies can carry pathogens, so as long as they come into contact with food, it is possible to leave them on food.
