Cicada breeding methods, what are the breeding methods of cicadas?

Cicadas reproduce mainly through the egg formula. At 6-7 of each year, it will change from pupae to adult and then lay eggs in just a few days. The preservation of cicada eggs and branches is directly related to the low hatching rate and the strength of cicada ant's physique, and must be paid attention to. According to the observation of the period.

The key to preservation is to grasp the three elements of temperature, humidity and communication.

1. Temperature. Maintain a constant temperature, generally the most suitable temperature is 0 10, if the above conditions are not reached, the temperature in spring can be, and in winter.

Outdoor plastic sheeting or shade is covered, and the temperature is too low to move indoors.

2. Humidity. Proper humidity is an important step in preserving the eggs, and too much humidity or too much will affect the life of cicada eggs. The humidity can be adjusted by spraying.

degree, spray more in spring and autumn, and less in winter. The spraying method is to spray some mist on the walls and floors at the right time to keep the room stable.

The air humidity can be.

In June and July of each year, they will turn from pupae to adults and then lay eggs in just a few days, starting from the eggs, through the process of the nymphs living in the ground, until the last time they shed their shells and become adults, and they are loud in the trees, usually one to two years. Among them, in the cicada their larvae are also called "nymphs", their male cicadas will make sounds to attract female cicadas to mate with him, it is using its sharp oviposition tube, inserted close to the tree to lay eggs, until the second year of larvae will hatch, and then live in the soil for a few years or even more than ten years before they can break out of the soil, in a long life they have to go through many times of shelling after a shelling is also when it becomes an adult, it will make a sound when it becomes an adult, and the sound made by the male cicada is at a high frequency of hundreds of times per second, constantly ** The two tympanic membranes in the abdomen are moved to make a high-pitched sound. This sound helps the female cicada determine the appropriate position of the male cicada for mating.

The cicada pupates into adults in June and July every summer, at this time the male cicada will make a sound to attract the female cicada to mate with it, after mating, the female cicada inserts the oviposition tube into the trunk to lay eggs, the eggs will hatch larvae in the second year, the cicada has two pairs of membranous wings, the head is wide and short, the compound eyes are distributed on both sides of the head, there are short antennae with bristles and 3 pairs of legs, and the body length of the adult is 2-5 cm.

Cicadas pupa into adults in June and July every summer, at this time the male cicada will make a sound to attract the female cicada to mate with it, after mating, the female cicada will insert the oviposition tube into the trunk to lay eggs, the eggs will hatch larvae in the second year, at this time live in the soil for several years or more than ten years, after many times of shedding the shell into an adult, for mating and reproduction.

The cicada has two pairs of membranous wings, the head is wide and short, the compound eyes are distributed on both sides of the head, there are short antennae like bristles, there are 3 pairs of legs, the color of the last instar larvae and the adult are similar, the body length of the adult is between 2-5 cm, and the length of the largest variety is about 7 cm.

The larvae of the cicada have strong forefeet and piercing-sucking mouthparts, absorb enough nutrients and will molt and feather at the end of June, at this time there will be black cracks on the back, green when they first emerge into adults, and then gradually grow and mature after the color will deepen, the lifespan after feathering is between 60-70 days, note that the cicada begins to lay eggs in July and August every year.

Cicadas are mainly distributed in tropical and temperate regions, usually inhabiting grasslands or forests, but also inhabiting deserts, among which the cicadas that appear in the summer of each year are the three-dog cicadas, which belong to the class of moth cicadas, in addition to the periodic cicadas, among which the seventeen-year-old cicada.

and the thirteen-year-old cicada is the most famous.

The mode of reproduction of cicadas is oviparous. Female cicadas use needle-like ovipositors to cut through the bark of young branches and lay their eggs in the branches. Cicada eggs spend the winter on the branches and hatch nymphs the following summer.

The nymph falls to the ground and burrows into the dirt, finding the roots of the tree to suck the sap. The nymphs inhabit the ground for several years, and do not crawl out of the ground until the evening before emergence, find a plant and fix it, burrow through a crack in the center of the dorsal back of the chest, and wait until the next day's dawn exoskeleton.

And the wings harden and you can fly. The male cicada has a vocalizer, the female cicada does not, and the female cicada will go to find the male cicada to mate and lay eggs, so that a generation is completed.

1.Collection and preservation of golden cicada eggs: Autumn harvest of golden cicada eggs, generally around August.

The golden cicada uses a small ovipositor on its tail to pierce young branches that are one to two years old and lay eggs on the branches. Most of them are fruit trees and poplars of white wax. Succulent branches are mainly tender and dry up and die within two hours of laying eggs, so most of the dry branches in the treetops basically have cicada eggs.

We have learned to distinguish the oval branches by the eggs, so we can collect the oovines. Reserve for next year. 2.

Post-harvest treatment and storage: After collecting the branches with cicada eggs, remove the dead leaves, remove the 100 branches that have been pruned at both ends and bundle them into bundles, store them in a dark and damp room, and wait for hatching in May of the following year. From the end of September to June of the following year, some eggs laid in the wild can be collected and observed under a microscope.

In May of the following year, put the bundled branches upright into the pot, keep the temperature at about 32 degrees, keep the humidity moist, spray when dry, ventilate, spray the branches with a sprayer until they are evenly soaked. 3.Incubation:

The larvae will be found hatching after about 35 days. If you look closely, you will see some larvae crawling out of the branches. At this time, pay attention to the number of larvae hatched.

Generally, within 4-5 days, the sand from the pot and the collected larvae should be sprinkled on the edge of the tree. Fourth, during the breeding process of golden cicadas, it is necessary to avoid burying egg branches, cicada ants or cicada eggs. This is simply completely contrary to the laws of nature and unscientific.

Only when cicada ants hatch in their natural state can they find ground fissures and grow underground. Cicada eggs do not move until they become cicada ants, and it is impossible to move underground to find their roots. Without the temperature and humidity of nature, cicada eggs would die quickly, not to mention that the larvae can hatch in the soil, which is simply amazing!

5.Harvest. According to the experience of farmers for many years, they would wrap a circle around the tree with scotch tape.

The height of this tape is about meters, and the adhesion is too low, which will cause the cicada catcher to bend over frequently and feel uncomfortable at the waist. Don't stick it too high. Because the tape is very slippery, the golden cicada can't climb up, so it can only turn around under the tape.

It's easy to catch. Intransitive verb tip: Cicada eggs are mainly harvested from gray stripes, poplars, and fruit branches.

Cicada egg larvae feed on the sap of plant roots, so you can use hanging branches, pruning, or spreading cicada ants when placing the eggs. Each branch contains about 100 cicada eggs, so there are about 3000-3500 cicada eggs per mu. This method can advance the original growth cycle by 2 to 5 years.

Generally, it can be unearthed after three years of cultivation. The survival rate during incubation has also increased to about 80%. So it's perfect for farming in rural areas.

Nowadays, the **all the way** of the golden cicada, as a delicacy, the golden cicada has been served on the table of large and small hotels. The outlook is promising. Using this method, the survival rate of farming is greatly improved.

Based on a minimum survival rate of 10% per acre, about 10,000 animals survive.

1. Every year in June and July, the pupa will turn into an adult and then lay eggs in just a few days, starting from the eggs, the nymphs live in the ground and roll their limbs, until the last time they shed their shells and become adults, and they are loud in the trees, which usually has one to two years.

2. Among them, in the cicadas, their larvae are also called "nymphs", their male cicadas will make sounds to attract female cicadas to mate with him, it uses its sharp oviposition tube, inserted close to the tree to lay eggs, until the second year of larvae will hatch, and then live in the soil for a few years or even more than ten years before breaking the soil.

3. In the long life, they have to go through many shellings, and the next shelling is also when it becomes an adult, and when it becomes an adult, it will make a sound, and the sound made by the male cicada is at a high frequency of hundreds of times per second, constantly moving the two tympanic membranes located in the abdomen to make a sharp and loud sound. This sound helps the female cicada determine the appropriate position of the male cicada for mating.

<> How do cicadas reproduce?

First of all, I tried to put a number of cicadas in my grandfather's idle birdcage, and I put some fresh branches in it, and changed them regularly to ensure that they could absorb the sap of the tree, and as a result, these cicadas died in one day at the earliest, and not more than three days at most, and as for the eggs, I didn't see a single egg. It is speculated that the cicadas may have a large demand for sap, and some of the broken twigs are fresh, but in the summer, the high temperature and water loss are also fast, which eventually leads to the lack of food and water and the death of the cicada.

Since the trick of letting cicadas lay eggs doesn't work, let's switch to collecting egg branches. The life of the cicada has to go through three late stages of egg, nymph and adult, among the three stages, the nymph period is the longest, with an average of at least 2 years, like the North American cycle cicada, and even the nymph period is as long as 17 years, so that the nymph can become a cicada, which is not very cost-effective, after all, the nymph is the most expensive and the most delicious stage, and I am reluctant to do experiments when I am a child.

Therefore, the eggs can only be collected, and the cicadas usually begin to appear in June every year and reach their peak in July, and the peak spawning season of the cicadas is actually concentrated in August and September.

When cicadas lay their eggs, they usually look for some small branches that are born in the year, and the diameter of these branches is usually not more than centimeters, which is very thin. It's also easy to identify such branches, and in late August, many cicadas have already laid their eggs, and since the cicadas use their sharp ovipositors to pick open the bark and lay their eggs inside, this is the destruction of the bark of the small branches, which we can see if we look closely.
