Do fruit flies grow out of thin air, and where do fruit flies come from?

No.

1. Human definition of some animals, these animals often have a negative impact on human life and production, even if some of them will not harm human health, they will still damage plants or materials in human possession. Beneficial insects generally refer to organisms that carry out beneficial effects on humans. Fruit flies, as decomposers, are beneficial insects.

For example, fruit flies feed first and foremost microorganisms that make fruits rot, such as yeast and bacteria, followed by sugary fruits, which clean up rotten fruits and give humans a clean environment.

2. The lifespan of sleep-deprived male fruit flies is the same as that of normal fruit flies, and the lifespan of sleep-deprived female fruit flies is shorter than that of normal fruit flies, but the average is only three days. You know, three days is about 6% 8% of the life expectancy of fruit flies.

3. White eyes and red eyes are controlled by genes on sex chromosomes, other bristles with straight hairs, long wings and short wings, and residual wings are all controlled by autosomes, and sex chromosomes will of course control many other traits, but biology is an experimental science, so we only look at obvious traits.

Fruit flies don't grow out of thin air. Fruit flies do not give birth for no reason, and are mostly attracted by the rotten or sweet smell of fruit. Due to their small size and easy passage through screens, fruit flies are common in home settings, with some living on rotting fruit and others living in fungal or fleshy flowersThe 1 complete life cycle of Drosophila is divided into 4 distinct periods:

Eggs – larvae – pupae – adults, adult fruit flies are commonly found around decaying plants and fruits, where they lay eggs.

Fruit flies don't disappear on their own.

Fruit flies don't disappear on their own. Adult fruit flies generally survive for 37 days at 25, although the survival period is not long, but the reproduction rate is relatively fast. For example, Drosophila melanogaster.

The female flies can lay 400 mm eggs at a time, and the larvae will break out of the shell after 22 hours in 25 environments. Fruit flies reproduce much faster than they die and have a hard time disappearing on their own.

Adult fruit flies are commonly found around spoilage plants and fruits, where they lay eggs. The larvae breed in spoiled fruits or other spoilage plant matter.

Fruit flies can be found on rotting fruits and vegetables, in garbage heaps, in breweries, kitchens, trains, ships, etc., in crowded areas.

Fruit flies are found in nature on rotting bark, rotten plants, fallen leaves, and fleshy fungi in flowers, under decaying grass, in orchards, in vegetable patches, and in forests.

Fruit flies are attracted to the smell of rotten fruit. Because fruit flies are small, they can enter the house through small gaps around windows or doors. When a fruit is overripe or starts to spoil, the fruit begins to ferment, producing alcohol that attracts fruit flies.

Fruit flies eat ripe and fermented fruits, and in doing so, they lay hundreds of eggs that can hatch into larvae in just a few hours. When buying fruit in the supermarket, the fruit in the supermarket starts to rot and attracts fruit flies, and you may take the fruit flies home with you when you buy the fruit.

Sometimes, fruit flies can lurk on fruits or vegetables and enter the room. Fruit flies lay eggs on the skin of fruits that have matured or fermented. So bananas and other fruits brought home from supermarkets or markets may already harbor fruit flies.

Fruit flies may have eggs hidden on fruits and vegetables before they are picked. Fruit that has been left unrefrigerated at home, both in the supermarket and at home, is a target for fruit fly infestation.

Fruit flies are particularly sensitive to the smell of fermented fruits, and can detect the smell of ripe fruits and vegetables from great distances, and their tiny bodies are good for going anywhere. If there's a plate of fruit on the table indoors, there's bound to be an outdoor fly or two looking for a way into the house.

Fruit flies are very small, so they can enter the house through gaps around doors and windows. Once inside the house, the flies quickly multiplied, and before they were discovered, they actually had a team that was already taking shape indoors.

Related Notes:

Drosophila is a small group of flies with a body length of millimeters. The body of the insect is mostly yellow-brown, and some are black. There are a pair of large and mostly bright red compound eyes on the head, three pairs of eye-edge bristles on the inside of the two compound eyes, the back of the compound eyes is slightly raised, forming a monocular triangle, and there is a pair of monocular bristles under the front and bottom of the three monocephalic eyes.

In the middle of the back of the head (above the back of the triangle of one eye), there is a pair of bristles on the top of the back of the head, and the two hairs are facing each other. It is also flanked by a pair of inner crest bristles and a pair of top bristles. The third segment of the antennae is oval or rounded, and the antennae are pinnate branched and born anteriorly inferior between the two complex limits.

Some male flies often have rows of bristles on the tarsus of their forefeet, called sex combs.

The head has many bristles, the antennae are oval or rounded with 3 segments, the antennae are pinnae, sometimes comb-shaped, and the compound eyes are bright red. The wings are short, R1 is also short, and the margins of the anterior veins are often notched. The larvae have 11 segments, each with a tiny hook-like spine with 1 ring.

The adult insect smells the fragrance and comes across the food he likesFruit fliesAnd it flew in. Even if you think you're in an enclosed space, because they're so small, they fly in without your naked eye noticing. Then the fruit flies give birth to small fruit flies, and slowly there are more and more fruit flies.

Drosophila is a small species of fly with a body length of between millimeters. The body of the insect is mostly yellow-brown, and some are black. There are two large, mostly bright red compound eyes on the head, and three pairs of eye margins on the inside of the two compound eyes.

Bristles, the 4 heads between the compound eyes are slightly raised, forming a monocular triangle, and there is a pair of monocular bristles under the front and bottom of the three monocephalic eyes.

Like humans, it is distributed all over the world, and more than 4,000 species have been described. Fruit flies spend the winter in human homes and are also common in homes due to their small size and easy access to screens.

Causes of the appearance of fruit flies indoors:

1. Smell attraction.

Fruit flies are easily attracted to fruits and vegetables, especially tomatoes and fermented substances, and fruit flies like to fly with the wind, so they can easily detect the smell of food, and the smell guides the fly to a suitable place to lay eggs.

2. Outdoor invasion.

Fruit flies breed in places where large amounts of organic matter are left in drains, empty bottles and cans, trash cans, mops and rags to ensure that the larvae have an adequate nutrient environment. Due to the small size of the fruit fly, it is easy to fly indoors. Fruit flies lay their eggs in the soil.

Hence the indoor potted plants.

It could also be the ** of Drosophila. Fruit flies will lurk indoors and wait until there are spoiled fruits, vegetables and other food sources before coming out to lay eggs and reproduce.

Fruit flies

Fruit fly insects, which are misleading and should be avoided. It refers to the insects of the insect class Drosophila of the order Drosophila, with more than 4,000 species described, including a series of model species such as Drosophila melanogaster and Drosophila melanogaster. It is widely used as an indoor and outdoor research material for genetic and evolutionary studies, especially in Drosophila melanogaster.

It is easy to grow, has a short life cycle, and can be cultivated in less than two weeks at room temperature.
