Cicada mainly feeds on the juice of plants, and domestic cicadas can provide it with branches, leaves, soybeans, corn and other foods. Because it feeds on plant juice, cicada is a kind of pest that does great harm to trees. Cicada mainly feeds on the sap of trees and other plants. Cicada in larval stage lives in the soil and lives by sucking the juice from plant roots. The same is true of cicada adults, who insert their sharp, needle-like mouths into the trunks of trees, crops or other plants and suck the juice all day to supplement nutrition and water.
Cicadas are distributed in temperate and tropical regions and inhabit deserts, grasslands and forests. In addition to the species of Lepidoptera, there are periodic cicadas, which appear in midsummer every year. The most famous periodic cicadas are 17-year cicada and 13-year cicada, also called prime cicada. Because the life cycle is a prime number, it will not meet the natural enemies encountered by the previous generation. Periodic cicadas appear at regular intervals in a certain area, and dozens to hundreds of dark brown cicada larvae emerge from the soil together, which is very spectacular. Some species are easy to distinguish in singing, behavior and morphology.
Know the breeding method
breeding ground
The golden cicada is mainly cultivated under the forest, and all kinds of fruit trees and timber trees can meet its 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, so it is difficult to interplant crops under trees such as fruit trees for more than three years. Golden cicada breeding is to use the space under the tree to grow by sucking the juice from the roots, and to develop breeding without affecting the growth of trees. You can kill two birds with one stone. The whole feeding process does not need feeding management, epidemic prevention and so on. , and does not take up 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 reproduction. Farmers can breed on their own, and if they breed on a small scale, they can also collect wild golden cicada eggs. However, it should be noted that wild golden cicada eggs have the disadvantages of inconsistent insect species, mixed varieties and low yield. In addition, it is best not to use cicada eggs on fruit trees, because the eggs on fruit trees are seriously harmed by pesticides and the survival rate is low, and large-scale breeding should be purchased from regular professional farmers. Bundle cicada seeds into 1 bundle every 50- 100 branches, put them in a basin or on the ground, and then treat them in a special way for later use. Golden cicadas collect eggs after laying eggs in autumn, usually around July of the lunar calendar. The golden cicada pierces the annual twig with a small thorn on its tail, and lays eggs on the twig, mostly fleshy branches such as fruit trees. After laying eggs, the twigs will dry up, so most of the branches with green lower ends and dry ends have cicada eggs.
Post-harvest treatment
After collecting branches with cicada eggs, remove dead leaves, cut off two ends, bundle 30 branches into a bundle, spread a layer of sand on the bottom of a large laundry basin, put the bundled branches vertically into the basin, keep the temperature at 28-34 degrees and 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 suitable temperature is the key to shorten the growth cycle of golden cicada and improve the hatching rate. Generally, the temperature should be controlled at 25-35℃, and the maximum temperature should not exceed 38℃. Too low temperature may prolong the emergence time of golden cicada, and too high temperature may lead to the egg death of golden cicada.
The general process is to make golden cicada eggs and land treatment in autumn and winter, and to hatch and breed golden cicadas in Spring Festival. Eggs can hatch from March to July every year. Heating is mainly carried out by coal stove, so we must pay attention to exhaust 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 the incubation period, spray water on the golden cicada eggs with a sprayer every day to keep them moist, and the spray water should be thin and uniform. Excessive wetting will do harm to the hatching of golden cicada. The larvae hatch in about fifteen days. At this time, you will see some larvae crawling around on the branches.
When about 20% larvae hatch, they should be buried. The area with thin and soft hair roots should be selected for burial, 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 of 65,438+00 cm, a width of 40 cm and a height of 20 cm, the bottom is paved with fine dry sand with a thickness of 5-65,438+00 cm, the egg branches are tied vertically or horizontally, and water mist is continuously sprayed by a small sprayer to maintain the high humidity of the air around the egg branches of the golden cicada, so that excess water droplets are adsorbed in the fine sand at the bottom. During the incubation period, it is necessary to constantly check the hatching situation of golden cicada eggs. When a small number of golden cicada larvae are found to be active, branches and fine sand can be planted in the breeding place.
