Can cicadas forcibly reproduce? How do cicadas reproduce?

That must be possible, forcibly reproduction is called through some means of human beings.

1. The ovipositor of the female cicada pierces a circle of small holes in the young branches, lays the eggs inside the wood of the tree, and punctures them with mouthparts at the lower end of the young branches.

A circle of phloem makes the branches cut off from water and nutrients, and the shoots gradually die. Branches with eggs are easily blown to the ground by the wind so that the hatchlings can burrow into the soil.

2. The eggs laid by the cicada hatch in half a month. The life period of young cicadas is particularly long, with the shortest being 2 to 3 years underground, generally.

4 5 years, the longest is 17 years. The young cicada has been living underground for a long time, with warm winters and cool summers, and there are few natural predators to threaten it.

After 4 to 5 molts, they have to get out of the ground, climb the branches and finally molt in turn, becoming adults.

Distribution of cicadas] 1. Tropical, inhabiting deserts, grasslands and forests. In addition to the species of the genus Mothcia that appear in midsummer every year, there are also Zhou.

Periods. The most famous periodic cicadas are the 17-year-old cicada and the 13-year-old cicada, which appear once at certain intervals in a certain area.

2. Some species are easier to identify from the sound, behavior and morphology. The male cicadas of each species make 3 different calls Ensemble sounds, which are affected by each.

diurnal weather changes and the regulation of other male cicada calls; courtship sounds before mating; The gruff sound of being caught or frightened and flying away. Larvae.

It lives in the soil and feeds on the sap of the roots of plants, and adults suck the sap from the upper parts of plants.

Reproduction of cicadas] 1. Acquisition of provenance, collection of eggs. Choose a place with dense trees and many cicadas, and use a long pole with tall branch shears at the top to lay eggs on the tree to kill the cicadas.

The thin dry branches of the tree are cut off. All sides are flat, dry and with an incomplete surface, and the subcutaneous xylem is inlaid with a large number of milky white oblong ovals.

The eggs are cicada eggs.

2. Cut off the excess eggless auspicious shoots in the upper part of the ovipositor nest, leave 10-15 cm eggless branches in the lower part of the oviposition nest traces, and bundle 50 into 1 small.

bundle and put it in a plastic bag. Plastic bags should have holes. Adults are collected, and mature larvae are collected at 18-24 hours. The harvester is the Lord of the tree.

The base of the stem is captured by irradiation with a flashlight. After harvesting, it is placed in a mesh box for feathering and spawning.

3. There are many natural enemies of nymphs and adults in pest control, such as toads, snakes, rats, hedgehogs, sparrows and other birds; Beauveria bassiana, zombie aeruginosa.

microorganisms such as fungi and cordyceps fungus (cicada fungus). Floods and pesticides and fertilizers are more harmful to nymphs or adults. The most important seasons are:

The egg stage on the tree is the occurrence period of "cicada ants", and the emergence period of old mature nymphs. The natural enemies are mainly ants and small red toons, and the control measures are used.

Dilute 100 times of the solution with strong chlorine to soak the branches with eggs, or use dichlorvos, strong chlorine and other agricultural herbs for soil treatment.

The larvae of cicadas live in the soil, sucking the sap of plant roots, weakening the tree, causing the branches to die, and affecting the growth of the tree. The larvae of cicadas live in the soil all their lives. When it is about to be feathered, it burrows out of the surface at dusk and at night, climbs on a tree, and then grabs the bark of the tree to molt and feather.

When a black crack appears on the back of a cicada pupa, the molting process begins. The whole process takes about an hour. At the end of June, the larvae begin to emerge into adults, with a maximum lifespan of about 60 to 70 days.

In late July, the female adults begin to lay eggs, and the peak oviposition is in early and mid-August, and the eggs are mostly laid on branches with a thickness of 4 to 5 mm. In summer, they make loud noises in the trees, suck the sap with a needle pricking mouthpiece, and the larvae inhabit the soil and suck the sap from the roots, which is harmful to the trees.

Commonly known as "Zhili", a kind of insect. The largest cicadas are 4 cm long and have black-brown wings at the base. In summer, they make loud noises in the trees, suck the sap with a needle pricking mouthpiece, and the larvae inhabit the soil and suck the sap from the roots, which is harmful to the trees.

The shells shed by cicadas can be used as medicinal herbs. The cicada is a large plant-sucking insect that is usually about five or six centimeters long. Their needle-like hollow mouths can pierce into trees and suck sap.

There are also different species of cicadas that are similar in shape but different in color. The cicada has three less sensitive eyespots in the middle of its eyes, and the wings are simply distributed with thin tubes that act as supports. These are the original features of ancient insect populations.

The soprano singer of the cicada family is a type of cicada known as the "double drummer".
