How can there be maggots in oranges???

Maggots inside oranges.

It is the larvae of the large fruit fly. Specific reasons:

Emerge from the soil in early to mid-May every year, adults will puncture the peel of citrus fruit in mid-to-late May - early to mid-July and then lay eggs, hatch into larvae on the inside of the fruit, the larvae will grow with citrus pulp as nutrition, and the damaged fruit will turn yellow in advance in September, most of it will fall off naturally, and after the damaged fruit falls to the ground, the larvae will overwinter in the soil and pupate, and will be unearthed in May of the following year.

How to identify oranges with insects: If the oranges are not ripe, and a few oranges turn yellow in advance, then it may be insect fruit, and careful observation can find an oviposition hole on the insect fruit. If you peel off the peel of an orange and find that a few petals are visibly deflated, be careful not to eat it.

In addition, there are more large fruit flies in oranges than in tangerines.

It is caused by environmental pollution that the big-headed fly breeds, lays eggs on the surface of orange fruits, grows with oranges, and the eggs enter the inside of the orange to grow and become insects. At present, there are no symptoms to prove that this insect disease can cause disease in people, but it should be correct to pay attention to dietary hygiene.

Because flies lay their eggs in oranges.

It was yesterday's TV report.

It's like the eggs of something are fine if you eat them.

The bug looked like a fly.

Now is the season to eat oranges again, but have you ever found such a situation, you carefully selected oranges outside, but when you peel them back home, there are maggots inside, what is going on? What causes it? The occurrence of such a situation will definitely surprise many consumers, in fact, this kind of situation will happen in oranges.

This is because when the oranges are still small, there are already fruit flies that lay their eggs on the top of the orange skin. Then, as the orange fruit grows, the egg gradually enters the inside of the orange fruit, and sucks the flesh inside, so that it slowly grows into maggots. If this happens, the quality of the orange will also be affected.

If consumers see maggots in oranges, does this feel very disgusting psychologically? If you accidentally eat it in the stomach, although the strong acid in the stomach can kill the larvae, finding this situation will always leave some shadows.

Therefore, when we choose oranges, we still have to distinguish carefully, and I believe that many consumers also have a general understanding of good varieties of oranges. If the oranges are shiny and dark yellow, the quality of the oranges is quite good. In addition, we need to carefully observe whether there are some small gray circles at the bottom of the orange, and from the side, it is the end with a long stalk, if it has been recessed, such an orange is suitable for purchase.

In particular, it should be noted that oranges should not be selected with small circles (female oranges) at the bottom, but with small dots (male oranges), and oranges with protruding oranges at the end of the long stem, as these oranges are generally sour. In addition, if the orange is too ripe or too green, it is not suitable to eat and buy such oranges. If you find that the orange peel is black, then don't choose it, and don't choose the orange petals with shriveled orange petals.

After all, maggots grow inside the flesh of oranges, so it is really impossible to prevent them, and we can only be more careful when selecting oranges.

The maggots in oranges are the larvae of fruit flies, which lay their eggs under the skin of citrus through an oviposition, so after hatching from eggs to larvae, the active larvae only feed on the pulp of the fruit and do not leave the fruit, so it is difficult to come into contact with the outside world and will not be contaminated with germs in the outside environment.

In addition, after being damaged, citrus itself will secrete terpenes and aromatic oils to seal the wound and avoid the invasion of external germs. Therefore, if the citrus fruit does not fester, mildew, it proves that the flesh is not contaminated with possible pathogenic bacteria, so even if there are active fruit fly larvae, they will not be harmful to human health due to ingestion of germs after ingestion.

There are two more common fruit flies that cause harm to citrus in China: Bactrocera minax and Bactrocera dorsalis. In addition, there are Mexican fruit flies, among others.

In fact, in addition to citrus, these fruit flies can also cause damage to more than a dozen other fruits. Fruit flies differ from ordinary flies in appearance: the thorax is mostly black with yellow stripes, the abdomen is thinner at the junction with the thorax, and the abdomen is mainly orange-yellow, round and pointed at the end.

The female fruit fly has a needle-like ovipositor at the end of her abdomen, which penetrates the citrus peel and lays her eggs under the peel. After hatching for several days, the larvae feed on the pulp. After growing to 3 instars (i.e., after the larvae molts twice), it bites through the peel, falls into the ground and pupates, and then emerges into an adult to complete a life cycle (about 1 month).

If a citrus with larvae is bought, it becomes a "citrus with maggots."

This is because the oranges are no longer fresh and have received some contamination during storage, so maggots will appear.

There is damage during the production of oranges, which attracts mosquitoes. Maggots do not appear out of thin air, this is caused by the broken area, so when buying fruit, it is necessary to check whether there is any damage.

It is the fruit fly (a fruit fly) that wraps its eggs in oranges, hatches them into larvae, lives and grows in oranges, and then burrows out of oranges and hatches into adults (fruit flies). Maggots are the larvae of large fruit flies.

It's disgusting, how to eat maggots, it seems to be the eggs laid by fruit flies ......

This year has been affected by many disasters ** caused by environmental changes and weather problems.

A kind of citrus with maggots, experts say, the maggots in this orange, just like the rice worms in rice and cabbage worms in cabbage, will not affect human health.

Maggot citrus refers to citrus with citrus larvae in the pulp.

Citrus fruit flies to go through"Egg-larvae-pupa-adult"There are 4 stages of growth and development, as people usually say"Citrus maggots"It is the larvae of this insect.

In terms of insect classification, citrus fruit flies belong to the order Diptera, Drosophilidae, and the subfamily oligochaetae. The mature larvae of citrus with maggots are 15-19 mm long, milky white conical, with a thin tip and a stout posterior end. The mouth hook is black, often retracted into the anterior chest.

The front valve is fan-shaped, with more than 30 milky protrusions; The rear valve blades are crescent-shaped, with 3 oblong pores and 4 clusters of flat hairs around it. Citrus fruit fly mainly harms citrus fruit trees, and its maggot-shaped larvae feed on citrus pulp, causing citrus fruit rot and fruit drop, resulting in reduced yield. When the larvae are old and mature, they fall to the ground with the fruit, climb out through the holes, pupate in the soil, overwinter in the soil, and emerge into adults in May of the following year.

**Affect the market, fruit farmers in order to insurance, use straw to protect the citrus, and watering for a certain period of time to keep the loss of water is not too serious, the temperature is high in summer, the cellar or fruit warehouse air is not circulated, resulting in a chemical reaction, resulting in maggots. But only partially.

It's a disease, a larvae of a pest called the big fly that lays eggs on oranges.

The oranges in Guangyuan, Sichuan have citrus maggots, the larvae of the citrus fruit fly, a kind of pest and disease, which is no different from the ordinary fruit worms, and it is no problem to eat them. Now the oranges in question are buried, and Guangyuan's oranges are not exported, and the oranges that ripen in November will not be available on the market now, so don't worry.

Now the orange has to be pinched, and if water is sprayed from a spot, the orange cannot be eaten because it has been injected with a potion, and there are parasites in it.

The large fruit fly is a citrus fruit parasite, which is very hidden, and oranges will grow maggots when they suffer from this parasite. You can't see the orange peel just by peeling it off, and you have to peel off the outer layer of each orange to see it.

Citrus bud maggots do not occur for a long time, but the damage caused by the damage cannot be underestimated. In recent years, orange orchards in some places have caused large losses due to the serious damage of flower buds and maggots, and some have even empty trees or empty orchards. According to the lessons learned, orange farmers are reminded to get out of the following misunderstandings in the prevention and control of citrus bud maggots.

No attention is paid to the prevention and control of maggots in flower buds. Some orange farmers think that citrus fruits in a large year, the tree is good, the fruiting rate is high, and the damage of flower buds maggots does not matter, and even thinks that it can play a role in thinning flowers, but this is not true. According to the survey, the damage caused by flower bud maggots is generally some flower buds with early buds and good flower quality.

These buds should be one of the main objects of "flower preservation". Flower bud maggots occur differently in different climates and soil conditions, and often occur in large numbers if there is sudden rainfall during the emergence period or in orange orchards with relatively humid soil. 2005 was a big year for citrus fruits, and last winter and this spring were low and rainy, and orange farmers should not ignore the control of flower buds and maggots.

Ground application is not taken seriously or applied too late. Some orange farmers think that applying pesticides to flower buds can solve the problem, so they omit ground application, and the result is that due to the large number of adult worms, the effect of flower bud application is not good. Or suffer serious losses due to the inaccurate application time of flower buds (often too late).

The production practice shows that ground application is an effective method for the prevention and control of citrus flower bud maggot, and ground application should be combined with flower bud application, with ground application as the main method and flower bud application as a supplement. The time of the emergence of the adult maggot of the flower bud is the same as that of the white of the flower bud like the size of a mung bean) or the flower bud is just white, and the adult is about to emerge (depending on the rainy period) spraying, which should be sooner rather than later. If the adult worm has already laid eggs on the tree before applying the pesticide on the ground, it often loses the control effect.

Adult trees should be sprayed all over the ground, and scattered trees and juvenile trees should only be sprayed within about 67 cm outside the canopy. Generally, spray powder pesticides with contact killing effect, such as 25 kg of carbaryl powder per mu or 30 35 kg of trichlorfon powder kg mixed with fine soil, and can also be sprayed with 2000 2500 times of dichlorvo liquid on the ground, once every 5 7 days, generally sprayed 1 2 times.

The flower buds become green before the pesticide is applied. Some orange farmers apply pesticides when the citrus buds are damaged like lanterns, the petals are green, or have small green spots, when it is too late. Crown spraying should be carried out before most of the flower buds turn white, 2 3 cm in diameter, and the adults have emerged from the tree without laying eggs.

Spray with 3000 4000 times of dichlorvos or 20 times of dichlorvos or 80 dichlorvos 1000 times of liquid, once every 3 5 days, 2 3 times in a row.

There is no problem, the bugs have long since died after human digestion, and the bugs are rich in protein. It's also good for people!

A larvae of a citrus fruit fly that specializes in parasitizing oranges.

It's okay, you can supplement protein.
