Crickets are known for their strong reproductive ability, rapid growth, and diverse diet. A single female can lay around 300 eggs per year. In summer, a loud cricket can be sold for 1 to 2 yuan, while in winter, the price can reach up to 100 yuan. Fried crickets are considered a delicacy, even better than prawns, and they are naturally green food, highly valued as a rare treat.
With the increasing use of fertilizers and pesticides, as well as manual collection, wild crickets have become nearly extinct. Therefore, artificial breeding of crickets has emerged as a promising and profitable business. Using off-season cultivation techniques, it is possible to breed crickets during both spring and winter. Eggs laid in early spring can be raised and sold during the winter season. Below are the key techniques involved in crickets farming.
(1) Biological Characteristics and Species
Crickets belong to the order Orthoptera and are one of the three major insect groups, along with grasshoppers and locusts. Their main diet includes grasshoppers, mealworms, carrots, lettuce, and beans. Males and females mate naturally. The crickets sold in markets or as pets are mainly for listening to their songs, while those used for breeding are sold at prices above 50 yuan per kilogram. The most popular species include iron tan, green ridge, and mountain ridge. Iron lice are often used for their musical sounds, while green cymbals are more ornamental due to their vibrant color.
(2) Breeding Locations
Sheds, open-air enclosures, and greenhouses are suitable for cricket farming. The first step is to build a shed, which makes construction and management easier. Choose a sunny and sheltered area. Avoid low-lying, wet, or windy spots. Once the site is selected, plant soybeans or wheat to provide natural food. After the seedlings sprout, insert bamboo poles into the soil about 20 cm deep. Secure the poles with sticks or additional bamboo. In windy areas, add support pillars. Cover the structure with mesh screens to prevent predators and escape, using smaller mesh sizes for better protection.
Indoor farming is also an effective method, especially in small spaces. It allows for easy management and is not affected by weather conditions. A simple structure made of cement and bricks, about 80 cm high, can be built. Use wooden boards or cement panels for the floor, and create multi-level setups. Place a 10 cm layer of sand on each level for future egg-laying. Fix iron mesh or screen cloth on top to form a three-dimensional breeding system.
(3) Introduction, Mating, and Egg-Laying
Fertilized eggs or adult crickets can be purchased from farms or caught in the wild. Ensure that the selection is healthy and active. A male-to-female ratio of 1:1 is ideal to avoid aggression. When a male cricket sings, the female will approach and mate. During this process, the male releases two white bubbles from his testes, which the female absorbs for fertilization. Under sufficient food supply, a female can produce about 300 eggs annually. She uses her ovipositor to dig into the soil and lay the eggs, covering them with surrounding dirt.
Eggs laid before August can hatch in the following summer, while those laid after August may take until the third summer to emerge.
(4) Artificial Incubation and Care
For artificial incubation, use a flat container filled with 5 cm of sand. Spread the eggs evenly, ensuring they don’t overlap. Cover them with another 3 cm of sand. Keep the sand thickness under 5 cm to avoid difficulty in hatching. Water the sand thoroughly without letting water pool at the bottom. Maintain a temperature between 25°C and 35°C. Spray water daily to keep the environment moist. This high-temperature incubation lasts about 40 days.
After this period, store the eggs in a refrigerator’s freezer compartment for one month. They will then begin to hatch. Initially, you’ll see small eyes beneath the eggs, which gradually move upward. At this point, transfer them to a greenhouse at 25–30°C for the second incubation phase. After about 30 days, the nymphs will hatch. Feed them fresh leaves or mix animal liver and egg yolk with leaves to make a nutritious paste. After 30–40 days of growth, the crickets can be sold as a green and healthy insect food.
