Why do apples grow bugs, and why do apples have bugs?

If you leave it for a long time, the insects will climb the mountain.

Because apples are sweets, it loves to eat, so.

Because apples are sweet, bugs like to eat sweets.

This is due to the fact that apples are damaged by heartworms during the growing season.

Heart-eating insects are the main pests of many drupes and kernel trees. Apples, on the other hand, are stone fruits, and their young fruits are vulnerable to different species of heart-eating insects during their growth period, depending on the neighboring orchards. If it is adjacent to the pear orchard, it is susceptible to the damage of pear heartworm or pear heartworm; If there is a peach orchard adjacent to the orchard, it is susceptible to the damage of peach heartworm or peach borer.

When the apple is young, the heartworm gnaws on the surface of the fruit as the larvae grows, and then burrows into the inside of the fruit to harm. When the damage is severe, it can cause the apple to fall or turn red early.

No. It's the larvae of these codling moths and moths of these lepidopteran insects.

Many kinds of fruits before the fruit is ripe, there are insects to ovulate in the bud, when the flower is real-time, and then the eggs are wrapped in the fruit (core), in the process of forming the fruit, the eggs have not hatched, and when the fruit is ripe, the eggs are also just hatching, and the larvae can eat in the fruit that looks intact on the surface without being discovered by the birds.

Once small insects appear in the fruit, you can wash it with concentrated salt water before eating, and the salt water has a sterilization and disinfection effect. It is better to soak for more than ten minutes.

Hello! According to your question, the insects in the apple are parasites, because parasites are mainly human as intermediate hosts, so they are called human parasites. The insects in the apples should be the insects that have grown on the apples, and generally speaking, they will not survive and grow and reproduce after eating.

Because when the apple is left for too long, the apple itself will have a state of decay, and in this case, it will attract small flying insects. Small flying insects mainly specialize in eating fruits, especially rotten fruits. If the apple is left out for too long, it will not be fresh, and the small flying insects will wander around the apple and eventually crawl on the apple to feed.

If you don't dispose of this fruit as soon as possible, and throw the fruit into the trash as soon as possible, then it is very likely that these small flying insects will be in all corners of the house, affecting people's daily life.

1. The name of the small flying insect Because these small flying insects are too small and fly very fast, it is difficult for us to see his specific appearance, but in fact, the name of this kind of insect is actually called fruit fly.

He is the same type of fly as we see in our daily life, and their habits are relatively similar, such as liking to eat some rotten food. However, the small flying insects in the house are very small, and some fruit flies are difficult to grow even if they eat a lot of food. Moreover, the time for them to produce and reproduce is relatively rapid, and when people see them, most of them are when they are young.

Second, the treatment method is not only that the apple is placed for too long, but it will lead to the spread of small flying insects, even if any kind of fruit is placed for too long, it will lead to such a situation. Therefore, when people keep fruits fresh, they must put them in the refrigerator for refrigeration. If there is no refrigeration condition, people try to eat the fruit as soon as possible after buying it, do not keep the fruit for too long, once the fruit begins to secrete small molecule organic acids, that is, when it attracts small flying insects to feed.

Small flying insects, because they do not pose much harm to people, and the living environment space is also limited, so people do not need to worry too much about how their behavior and activities will affect people.

Sitting under the apple tree and remembering the day of picking apples was half happy and half sad, that morning the three of us walked together, came to the apple tree, carrying a fruit basket and bamboo pole, saw the apples to be so red and green, the light of the apples from the inside out, let us not take our eyes off, similar to the autumn rain after the earth is full of life, then we plan how to pick such a number of cherished apples, the apples are like a star-studded group, in the top of our heads radiant, we began to look for branches and pick fruits.

Standing on the surface of the earth's crust of the law of gravitation, three fruit-eating people, with apple-like hearts projected in their eyes, we climbed from the ground to the sky and watched the angle of the apple tree steadily.

At this time, we saw that there were still a few red and tender apples at the top of the tree, but this height made it difficult for us to close ourselves up, and suddenly we heard the companion next to us say that he was very good at climbing the tree, and then he climbed up with all his might, and he stood on the apple tree and picked those apples.

Standing under the tree, we looked at him and said, brother, my brother, it is you who will never forget, climb the tree to pick fruits, it is always you who help us, with our perfect encouragement, he finally picked those few hard apples.

At this time we walked to the pool, after cleaning the apples, I picked up the fruit knife and fell with the knife, peeling off the skin of the apples layer by layer, and then I bit off the heart of the apple again and again, when I was halfway through eating, suddenly the insect came out of the side brick of the apple, it smiled at me, I was angry at it, I quickly took the apple away, the insect was not convinced, had to jump to my side, at this time my face did not change, and the insect disappeared with a flick of my finger.

Sitting under the apple tree, I was furious when I remembered the naughty insects that day, I lay under the tree and looked up at the sky, and saw countless insects collapse from the tree, and fell down without saying a word.

The insect in the apple is the apple heartworm, a species of the genus Heartworm in the family Lepidoptera. This insect has a wide distribution range and occurs in all apple producing areas. It mainly harms apples, pears, hawthorns, peaches, plums and other fruit trees.

Adults are long, with a wingspan of 10 to 11 mm. There is very little morphological difference between male and female moths. The whole is dark brown with a purple sheen, the head scales are gray, the antennae are dark brown on the back, and the ends of each segment are white.

The lips are grey and slightly upturned. The anterior margin of the forewings has 7 9 groups of white hook-like stripes of varying sizes, and there are many white scales on the surface of the wings to form white spots, and the white spots near the outer margin are neatly arranged. <

It is widely distributed and has a miscellaneous diet, which can harm more than 110 kinds of plants.

2. Peach heartworm.

Harm apples, pears, peaches, dates, hawthorns and other fruit trees. In the area of the Yellow River, 1 3 generations occur per year, and 2 generations are the main ones. The old mature larvae form a flat round cocoon in the soil under the tree for the winter, and the larvae are unearthed in May and June of the following year and then form a long cocoon and pupate in the ground.

Generally, the peak period of overwintering adults is from late June to early July, and the second generation of eggs and larvae is the fruit-eating period in early to mid-August.

3. Golden-veined fine moth.

4 to 5 generations occur in a year. Pupae spend the winter in the fallen leaves of the victims. From March to April of the second year, the budding and blooming period of apples is the emergence period of overwintering adults.

Adults like to fly around the trunk of a tree in the morning or evening to mate and lay eggs. Its spawning sites are mostly concentrated in apple varieties that germinate early.
