Do grasshoppers lay eggs? When is the spawning season?

Grasshoppers, also known as leeches, lay eggs to reproduce. Summer and autumn are the peak breeding seasons.

Raised in captivity. Swamp and mud pond aquaculture:

Swamps and mud ponds are lush with aquatic plants, more organic matter and humus content, and plankton and aquatic plants are abundant. This model has a low investment cost and is more troublesome to manage and fish.

Rice paddy interculture. Digging ditches and ditches in rice fields as the main activity places of leeches, generally excavated according to the shape of "well" and "ten", divided into two types: ditch and mud pond. The chute requires uniform distribution, extending in all directions, which is conducive to the growth and foraging of leeches, generally wide meters, water depth meters, and the area of the chute accounts for about 10% of the total area; The mud pond type is to dig the mud pond inside the paddy field, the mud pond is connected with the paddy field ditch, the ditch width and the ditch depth are about meters, and the depth is about 15% of the paddy field, and the pesticide application of the paddy field is harmful to leeches.

Generally, choose high-efficiency and low-toxicity pesticides, do not use chemical fertilizers, and it is better to use animal manure, which is not only conducive to rice harvest, but also a good feed for leeches.

Cement pond culture.

Build a cement pool of about 20 square meters, 3 meters wide, 7 meters long, 1 meter - meter high, water depth meters, do a good job of inlet and drainage facilities, outdoor cement pool needs to put aquatic plants and other plants, so that leeches inhabit. The newly built cement pond can not immediately put the leeches, the alkaline substances of the pool body (Portland cement, calcium hydroxide, etc.) need to go through 20 days of desalination before the seedlings, can not be a one-time seedling, after the overall environmental conditions of the breeding pond tend to the overall balance of the food chain, in order to gradually increase the amount of seeds, generally 100 per square meter.

Standardized intensive intensive culture:

It is recommended that the pond is 90 meters long, 7-8 meters wide, the depth of the pond is meters, the depth of the water is meters, the inlet and drainage facilities are done, the construction of soil habitats, high above the water surface, planting aquatic plants on it, to shade and protect from the sun, and the use of 40 mesh polyethylene mesh to do a good job of anti-escape measures. Generally, 2,000 leeches are planted per mu of water area.

Grasshoppers, also known as leeches, lay eggs to reproduce.

There are many eggs, leeches are self-reproducing, excellent large leech seedlings are 40-50 per kilogram, hermaphroditic, allogeneic mating, each leech can reproduce and lay eggs. It lays eggs more than 3 times a year, and can lay 3-5 cocoons each time, and can lay 100-200 leeches throughout the year.

Summer and autumn are the peak breeding seasons.

The eggs of the locust are nearly transparent yellowish granular, the eggs of the locust are generally hatched in the wet soil, the normal incubation temperature should be about 20 °C, the cocoon of the eggs of the locust laid in the soil is 9 15 mm long, 6 10 mm wide.

Under natural conditions, leeches lay their egg cocoons in the soil, and the leech egg cocoons are 9 15 mm long and 6 10 mm wide.

At night. Grasshoppers usually come out most at night. Grasshoppers generally inhabit the moist soil during the day and are not easy to see, but they come out more often at night when foraging, and more often on rainy days.

When catching, wrap pig, cow, sheep blood clots or Changchan pig liver with weeds, tie a stone with an appropriate weight to slowly recall the head, and then tie a wooden stick or wrap it with grass and hemp, and place it separately and insert it into the water at a distance.

Effectiveness of the locust:

Grasshopper is also known as leech, its effect is to break the blood, chase away stasis, pass through menstruation, the application range is very wide, mainly for the disease of blood stasis to regulate, through the grasshopper can prevent thrombosis, reduce platelet activity, inhibit platelet release. In general, it can improve the symptoms related to blood stasis, including amenorrhea in women, as well as cerebral thrombosis, heart disease, myocardial infarction, and angina, which are the best range of locusts.

Grasshoppers can significantly reduce blood cholesterol and triglycerides, which has great benefits in protecting blood vessels. In addition, the grasshopper also has a very obvious inhibitory effect on malignant tumors, including the growth of liver cancer, which has a strong inhibitory effect, and it is best to use it reasonably under the guidance of a doctor. <>

After the mature female and male grasshoppers mate, the female grasshoppers insert their oviposition tubes into the dry soil at a depth of 10 cm and lay about 50 white-to-yellow eggs. When laying eggs, the female secretes a white substance to form a cylindrical plug, and then lays the eggs. Grasshopper eggs hatch in about 21 days.

Summer and autumn are the breeding seasons for grasshoppers.

<> locusts appear in spring, summer and autumn, and when the temperature is lower than 14 in winter, they will stop feeding and die. Its lifespan is only 2-3 months, but the ability to reproduce is extremely strong, and different varieties, at different temperatures, can reproduce for 1-3 generations a year.
