What food do domestic cicadas usually eat?
Branches and leaves, soybeans, corn

The cicada lives mainly by sucking the juice of plants, and the domestic cicada can provide it with branches, leaves, soybeans, corn and other foods. Because it feeds on plant juice, cicada is a pest that is very harmful to trees. The cicada mainly feeds on the sap of trees and other plants. The cicada in the larval stage lives in the soil and lives by sucking the sap from the roots of plants. The same is true of cicada adults, who insert their sharp, needle-like mouths into trunks, crops or other plants' trunks and suck juice all day long to supplement nutrition and water.

Cicadas are distributed in temperate and tropical regions and inhabit deserts, grasslands and forests. There are periodic cicadas in addition to the species of the genus Lepidoptera, which appears in midsummer every year. The most famous periodic cicadas are 17-year cicadas and 13-year cicadas, also known as prime cicadas. Because the life cycle is prime, they will not meet the natural enemies they met in the previous generation. Periodic cicadas occur once in a certain area at regular intervals, when dozens to hundreds of dark brown cicada larvae emerge from the soil together, which is very spectacular. Some species are easy to distinguish from each other in singing, behavior and morphology.

Know the breeding method

Breeding ground

Golden cicadas are mainly cultivated under forests, and all kinds of fruit trees and timber trees can meet their growth needs. There is no need to invest in building sites and houses, and there is no need to buy other breeding facilities. China is rich in forest resources, and it is difficult to interplant crops under fruit trees and other trees for more than three years. Golden cicada breeding is to use the space under trees to grow by sucking the juice of tree roots, and to develop breeding without affecting the growth of trees. It can be said that it can kill two birds with one stone. The whole breeding process does not need feeding management, epidemic prevention, etc., and does not occupy labor. Under the condition of solving the technology and market of golden cicada breeding, golden cicada breeding is a good project for laid-off workers to develop re-employment and farmers to engage in the tertiary industry.

Egg collection

Excellent golden cicada eggs are necessary for the success of golden cicada breeding. Farmers can breed on their own or collect wild golden cicada eggs if they breed on a small scale. However, it should be noted that wild golden cicada eggs have the disadvantages of inconsistent insects, mixed varieties and low yield. In addition, it is best not to use golden cicada eggs in fruit trees, because the eggs in fruit trees are seriously harmed by pesticides and the survival rate is low, while large-scale breeding should be purchased from regular professional farmers. Tie branches with golden cicada eggs into 1 bundle every 50- 100, put them in pots or on the ground, and then treat them by special methods for later use. Eggs are collected after golden cicadas lay eggs in autumn, usually around July of the lunar calendar. The golden cicada pierces the annual twig with a small thorn in its tail, and lays its eggs in the twig, mostly succulent branches such as fruit trees. After laying eggs, the twig will dry up, so most branches with green lower ends and dry ends have cicada eggs.

Post-harvest treatment

After collecting the branches with cicada eggs, remove the dry leaves, cut off the two ends, bundle thirty branches into a bundle, spread a layer of sand on the bottom of a big laundry basin, put the bundled branches into the basin vertically, keep the temperature at 28-34 degrees, and keep the humidity moist, that is, spray them when they are dry, and spray them with a sprayer until they are soaked.

hatch

The most important condition for hatching golden cicada eggs is temperature, and a suitable temperature is the key to shorten the growth cycle and improve the hatching rate of golden cicada. Generally, the temperature should be controlled at 25-35℃, and the maximum temperature should not exceed 38℃. If the temperature is too low, it may prolong the emergence time of golden cicada, and if it is too high, it may cause the eggs of golden cicada to die.

The general process is to do golden cicada eggs and land treatment in autumn and winter, and to do golden cicada hatching and breeding in Spring Festival. Eggs can be hatched from March to July every year. The heating is mainly carried out by using coal stoves, and attention must be paid to exhausting the gas in the incubation room to prevent damage to the golden cicada eggs. Maintaining proper humidity is particularly important to improve the hatching rate of golden cicada. During hatching, spray water on golden cicada eggs every day with a sprayer to keep them moist, and the spray should be fine and even. Excessive wetting will cause damage to golden cicada hatching. Larvae hatch in about fifteen days. At this time, you will see some larvae crawling up and down the branches.

When about 20% of the larvae hatch, they should be buried. The area with fine and soft hair roots should be selected for burying, so that the larvae can absorb nutrients from the roots, and it is best to choose the land where honeysuckle is planted. In a plastic basin with a length of10cm, a width of 40cm and a height of 20cm, fine dry sand with a thickness of 5 to10cm is spread on the bottom, and the egg branches are placed vertically or horizontally in bundles, and the mist is continuously sprayed with a small sprayer to keep the high humidity of the air around the golden cicada egg branches, so that the redundant water drops are absorbed in the fine sand at the bottom. During the incubation period, the hatching situation of golden cicada eggs should be constantly checked. When a small number of golden cicada larvae are found to be active, the branches and fine sand can be placed in the breeding place for planting.
