1. What conditions do cicada ants (insects hatched from cicada eggs) need in order to burrow into the roots of trees underground?

The larvae grow underground for more than two to three years. They will emerge from the roots of trees in spring, summer and autumn (most in summer) and metamorphose into cicadas. They will metamorphose successfully in the evening. In the morning, when the sun comes out and the wings are dry, they can fly and mate. After mating, they will lay eggs. Breeding method (I) To raise cicadas, you should first provide a forest with sufficient nutrients. To cultivate a forest, you should first cultivate broad-leaved seedlings. You can plant broad-leaved trees such as willows, poplars, and elms. The trunks should be shorter and covered with nylon nets. The adults collected in summer are placed on the trees in the net room to lay eggs, and then the eggs are collected; the branches with cicada eggs collected in autumn are also buried at the roots of the trees in the net room. You can also combine the planting of fruit trees to raise cicadas. For example, you can plant 300-660 square meters of peach trees, lower the trunks, surround the peach orchard with welded nets, and cover the top with nylon nets. Release the adult cicadas in the peach orchard and bury cicada eggs at the roots of the peach trees. (II) Feeding and management: For the growth and reproduction of cicadas, high-quality feed should be provided first. Such as poplar, willow, elm or various fruit trees. Root and tuber plants, such as potatoes, sweet potatoes, and yams, should also be intercropped to provide feed for cicadas and larvae. Provide good environmental conditions. The depth of cicada eggs is 30-50 cm, and they must be buried in sunny, frost-proof, soft, fertile, pollution-free, and humidity-appropriate places. In winter, wheat straw, rice straw, corn stalks, etc. should be covered to maintain ground temperature. Construct production sites. In addition to naturally collecting cicada eggs, large net rooms can be built to provide space for adult cicadas to lay eggs, and prevent adult cicadas from escaping and being preyed on by enemies. Fruit trees in abandoned orchards can be used, or seedlings can be planted in abandoned orchards, and fences can be erected around them with cement columns or wooden poles, surrounded by wire mesh, and nylon mesh on the top. The adults that have emerged or been harvested mate and lay eggs in the net room, gradually forming a seed source area, and there is no need to collect seed eggs from the wild. Reproduction technology (i) Obtaining seed sources and collecting eggs. Choose a place with dense trees and many cicadas, and use a long pole with a high branch pruner on the top to cut off the thin dry branches on the tree that have been killed by cicada egg laying. Any branch that is flat and dry on one side and has an incomplete surface, and has a large number of milky white long oval eggs embedded in the subcutaneous wood, is a cicada egg. Cut off the excess eggless dead branches above the egg-laying nest, and leave 10-15 cm eggless branches below the egg-laying nest. Bundle 50 branches into a small bundle and put them in a plastic bag. The plastic bag should have a hole. Collect adults, and collect mature larvae at 18-24. The harvester uses a flashlight to catch them at the base of the tree trunk. After harvesting, put them in a gauze box to pupate and lay eggs. Plant shrub-like host plants in the egg-laying gauze box, and you can plant some fruit trees. You can also catch adults on the tree. (ii) Burying eggs. Collect branches with eggs collected from the wild or at the seed source site and incubate them indoors. Spread 5-10 cm of fine dry sand at the bottom of a wooden or plastic box that is 70 cm long, 40 cm wide, and 20 cm high, and place the egg branches in bundles vertically or horizontally on it. Use a small sprayer to spray mist water continuously to keep the air at a high humidity. During this period, if nymphs are found, the branches with eggs will be buried in the farm with sand. The burial time is from September to October (2-year eggs), and the eggs of the current year can only be buried in June or July of the following year. The burial position is 1 meter away from the base of the trunk under the host plant tree. Dig a narrow trench 30-50 cm deep, such as ring, square, triangle, parallel or radial, so as to facilitate digging or capture. After burying, cover the soil and compact it, and keep a record of the trench shape and depth. After hatching, the cicada starts to grow in June. It weighs 1 gram in the first year, and its whole body and eyes are milky white; the next year, it weighs 3 grams, its whole body pigment deepens, and its eyes are pink; the third year, the nymphs mature, weighing 4-4.5 grams, with an average of 210 per kilogram, with brown body color and dark gray eyes. 4. Disease and Pest Control There are many natural enemies of nymphs and adults, such as toads, snakes, mice, hedgehogs, sparrows and other birds; microorganisms such as Beauveria bassiana, Metarhizium anisopliae and Cordyceps sinensis (Cicada Flower Fungus). Floods and pesticides and fertilizers are more harmful to nymphs or adults. The most important season is the egg stage of "Cicada Ants" on the tree, and the emergence of mature nymphs. The natural enemies of the egg stage and "Cicada Ants" on the tree are mainly ants and red small flower toon. The prevention and control measures are to soak the branches with eggs in a solution diluted 100 times with strong chlorine, or to treat the soil with pesticides such as dichlorvos and strong chlorine.

2. How many years is the incubation period of cicadas?

The average hatching time is two to three years, and the maximum life span of cicadas is 17 years.

The larvae of different cicada species live underground for different periods of time, ranging from 3 to 5 years, and the longest is 17 years.

Generally 3 to 5 years, the longest is 17 years

The life cycle of cicadas is unlimited. The life cycle of cicadas in South America is 13 years...no more than 18 years.

2-7 years, but no longer than 18 years.

3. How long is the life cycle of summer cicadas?

The life cycle of a cicada is generally 3-9 years, and the life cycle of different cicadas is also different. The cicada in North America can live up to 17 years, and is also known as the "17-year cicada".

Every year in June and July, it will transform from a pupa into an adult and then lay eggs in just a few days. From the egg, the weak insect lives in the ground until the last molting to become an adult, singing loudly in the trees.

Among the cicadas, their larvae are also called "nymphs". Their male cicadas will make sounds to attract female cicadas to mate with them. They use their pointed ovipositors to lay eggs in trees. The larvae will not hatch until the second year, and will live in the soil for several years or even more than ten years before breaking out of the soil.

The song "Zhi Liao Zhi Liao" about cicadas, written by Gong H. Composed and sung.

I know, I know, why are you calling

Little belly, are you hungry?

Where's your mother?

It's getting dark, where to sleep?

I know, I know, don't be afraid

I'll help you fill your stomach first.

If you forget the way home

I will give you a warm embrace

Even if the autumn wind blows, even if the snow falls

I will accompany you slowly

Wait until the spring breeze blows, wait until the leaves fall

You gradually grow up

I know, I know, don't be afraid

I'll help you fill your stomach first.

If you forget the way home

I will give you a warm embrace

Even if the autumn wind blows, even if the snow falls

I will accompany you slowly

Wait until the spring breeze blows, wait until the leaves fall

You gradually grow up

I will accompany you slowly

Wait until the spring breeze blows, wait until the leaves fall

You gradually grow up

Different species of cicadas have different life cycles.

The life cycle of French cicadas is mostly 4 years, while in North America there are cicadas that can live up to 17 years. The life span of Chinese cicadas is mostly 3 to 7 years, nearly half of which live for 5 years, and a few can live for 8 to 9 years.

Biologists generally believe that cicadas are the longest-lived insects in the world.

The life of a cicada is like this: the pregnant female cicada uses the ovipositor on the tail to drill holes in the tree branches, penetrate the wood and reach the pith, and lay several eggs in each hole. There are dozens of holes in total, and the total number of eggs is generally 300 to 400, and up to 600. Like other weak creatures in nature, most of them do not survive to adulthood. After the eggs hatch on their own, the larvae drill out of the holes and molt for the first time on the branches. After a few hours, the epidermis keratinizes and hardens, and then they fall to the ground, dig the soil with their front claws, burrow into the mud, and spend long years in the dark, surviving and growing up by sucking the sap from the roots of the tree. Most of the adult cicadas that drill out of the ground and see the light again after molting have a survival period of less than half a month, with the shortest being only a pitiful 3 days, and the longest survival period for black grasshopper cicada adults is only 45 to 60 days in the sun.
