Culture Technique of Cicada japonica

The cultivation of golden cicada needs to pay attention to five parts, namely, feed supply, environmental conditions, epidemic prevention, production facilities and harvesting and processing. The healthy tree species with developed root system, luxuriant growth and more juice should be selected, and the breeding depth of golden cicada should be 30-50 cm. There are many nymphs and adults after emergence, which should be paid attention to and protected during culture.

1. Feed supply: choose healthy tree species with developed root system, luxuriant growth and more juice, such as poplar, elm, willow, paulownia or all kinds of fruit trees in the orchard. In addition, but also intercropping some rhizome plants, such as potatoes, sweet potatoes, yams and so on.

2. Environmental conditions: the breeding depth of golden cicada is 30-50 cm, should be sunny and frostproof, the soil is soft, fertile, pollution-free, not too dry, the water content is too high or the phenomenon of stagnant water exists. To ensure the normal growth and development of host plant roots, tender, developed and succulent, wheat straw, rice straw and corn straw should be covered in the breeding area in winter to maintain the ground temperature.

3. Epidemic prevention and damage prevention: there are many unearthed nymphs and adult natural enemies, such as toads, snakes, rodents, hedgehogs, wild cats, sparrows and mantis, and other microorganisms such as Beauveria bassiana, Beauveria bassiana and entomogenous algae. In addition, the pollution of floods and pesticides and chemical fertilizers do great harm to nymphs (cicadas) or cicadas, which should be paid attention to and protected when breeding.

4. Production facilities: build production facilities for adults and nymphs. In addition to naturally collecting cicada eggs, screen sheds can be built to provide space for golden cicada adults to lay eggs. Fruit trees in abandoned orchards can be used to replant fruit tree seedlings. Around the use of cement columns or bamboo sticks to build a fence, and then set up iron wire in the middle, etc., covered with nylon window screen, in which adults can mate and lay eggs. In the future, the number of adults can be retained according to the needs, and there is no need to collect provenances from the wild.

5. Harvest and processing: from mid-late June (around the Summer Solstice) to early August (around the Beginning of Autumn), it is the best season for field harvest, among which the weather is the most concentrated in early July or after rain. Nymphs dig holes in the wet and soft ground with a pair of jagged forefeet. After climbing out of the ground, they do short-term exercise on the ground. Then Fan Yuan tree trunks or scaffolding are ready to molt. At 4-6 o'clock in the morning, they become cicadas, which can be illuminated by flashlights. At night, they can be caught on the ground under the trees and on the tree trunks, or the feathered young cicadas can be caught in the trees in the early morning.
