CATDOLL : CATDOLL: Mealworm adults: Temperature 28, Humidity 60-70, I observed them huddled together during the day and night? I didn't see them mating? I didn't see them laying eggs?

1. Mealworm adults: Temperature 28, Humidity 60-70, I observed them huddled together during the day and night? I didn't see them mating? I didn't see them laying eggs?

1. Humidity should be determined between 70-75%.

2. Each tray (600*400*70) should contain 200-250 grams of adult insects. Too low a density will affect the probability of mating.

3. The standard mesh number of the spawning screen is 12 meshes, that is, 12 holes are distributed every 25 mm in length.

4. Since the egg-laying screen is attached to the newspaper on the bottom of the imaginal tray, the amount of feed that leaks down is limited. This is necessary as it is the feed for the larvae after hatching.

5. It should be noted that there is a kind of tray that has wooden strips nailed to the bottom, so there is a large gap between the newspaper and the screen. The breeding method of this tray is different from the above. It uses the method of laying feed underneath in advance to catch eggs, so you can't see eggs on the newspaper under the feed. All the eggs are in the feed. The only way is to take out the newspaper and feed together, put them together for more than half a month, and then observe the hatching situation to judge the egg-laying situation.

2. Where can I buy mealworms in Shangrao?

It seems that there is no large-scale one. The larger one in the south is the Tianxiahaochong Yellow Mealworm Breeding Base, which can be used as a reference. Don't forget to give me your share

3. Is mealworm a yellow worm?

Yellow mealworms, also known as mealworms, belong to the order Coleoptera, family Pseudocephagidae, and genus Mealworm in insect taxonomy. They are native to North America and were introduced to my country from the Soviet Union in the 1950s. Dried yellow mealworms contain 30% fat and more than 50% protein. In addition, they also contain macroelements such as phosphorus, potassium, iron, sodium, and aluminum, as well as a variety of trace elements. They have high application value.

4. How to breed mealworms.

Mealworms are omnivorous animals. They can feed on grains, bran, fruit peels, vegetable leaves, etc. The growth and development of mealworms in their life cycle is the same as that of many other insects. They go through four stages: egg-larva-pupa-adult. The crawling larvae of mealworms are used as feed. The technical regulations for artificial breeding are as follows.

1. Production of egg-laying box, pupal transformation box, incubation box and growth box

The egg-laying box is 70X50X10 cm, with 1 cm thick wooden strips at the bottom, and the iron screen is tightened and nailed firmly. The surrounding area is taped with tape to prevent escape. The specifications of the pupal box are the same as the egg-laying box, but there is no iron screen at the bottom, and the wooden boards are nailed directly into a box. The incubator and growth box are 80X60X10 cm, and the bottom is nailed into a box with wooden boards.

2 insects to choose from

They can be purchased in the market and must be of uniform size, active crawling, dark intersegmental color, smooth body wall, and mature larvae over 25 cm in length.

3. Mature larvae rearing

In the growth box, 2 kg of insects can be placed per square meter, and the thickness should not exceed 2 cm. Feed: 70% wheat bran, 15% cornmeal, and 15% cakes. Usually, green leaves or melon and fruit peels are added to supplement water. The suitable temperature for larvae is 13-32℃. The optimum humidity is 80%-85%. Larvae can move and feed during the day and night, but are more active at night.

4 Management of pupae

Pupae are milky white at first, usually 15-17mm long, floating on the surface of feed. Put 2cm bran in the pupal transformation box, put the pupae picked out every day on it, and wait for them to become adults. Pupae should be placed in a ventilated and heat-insulating environment, not too humid to prevent the pupae from rotting. The pupal period is short. When the temperature is 10-20℃, it can emerge as an adult in 15-20 days; when the temperature is 25-30℃, it can emerge as an adult in 6-8 days.

5 Management of Adult Insects

After the adult insects have emerged and their body color turns dark brown, they will be moved to the egg-laying box for breeding. The egg-laying box can be placed in an incubator and a growth box. Sprinkle a layer of feed about 1 cm thick in the egg-laying box, and then put a layer of fresh vegetable leaves, and the adults will be scattered and hidden under the leaves. These leaves are their feed, mainly to provide water and increase vitamins. They should be put in as they eat, but not in excess to avoid excessive humidity. Vegetable leaves rot and deteriorate. When laying eggs, most of the adults drill into the bottom between the feed and the gauze, extend the ovipositor, pass through the mesh holes, and lay eggs in the feed under the net. Artificial breeding takes advantage of its habit of laying eggs downwards, and uses a net to separate it from the eggs to prevent the adults from eating the eggs. Therefore, the feed on the net should not be too thick, otherwise the adults will also lay eggs in the feed on the net.

4-5 days after the adult insects emerge from their pupae, they begin to mate and lay eggs. The adult insects mate day and night, and each mating takes several hours. They mate and lay eggs many times in their life. Each female insect can lay 6-15 eggs each time, and each female insect can lay 30-350 eggs in its lifetime. The life span of the adult insects is 3-4 months.

6 Hatching of eggs

The hatching time of mealworm fertilized eggs is closely related to the ambient temperature. Under the condition of 25-30℃, it only takes 4-7 days to hatch. In order to shorten the hatching period, the indoor temperature should be kept as warm as possible when artificially cultivating mealworms to artificially create the optimal hatching temperature. Generally, the egg-laying box is moved to another hatching box at intervals of about 7 days. The feed and eggs in the original hatching box can be hatched until all the larvae are hatched, the feed is eaten up, the feces are sieved out, and new feed is replaced.

7 Larvae rearing

When the feed during the hatching period is basically eaten, the insect feces should be screened out. Put the screened insects back into the original box for feeding, and add 2-3 times the amount of feed as the insects, or add less every day, and remove the feces every 3-5 days. Put some green vegetable leaves, radish slices, etc. on the feed at ordinary times. In the summer when the temperature is high, pay attention to ventilation and cooling; in other seasons when the temperature is low, add heating equipment indoors. Maintain a suitable living temperature of 13-32℃, and the optimum temperature is 25-29℃. When the temperature is below 10℃, there is very little activity, and it can safely overwinter above 0℃. If the temperature is below 0℃ or above 35℃, there is a risk of freezing to death or heat death.

8. Things to note

The hatching of eggs, larvae, pupae, and adults should be raised separately and must not be mixed. Mixed breeding is not convenient for feeding according to different requirements, and adults are prone to eat eggs and larvae are prone to eat pupae during foraging. The thickness of the larvae should not exceed 2-3 cm to avoid heat, and the size requirements are basically the same. The amount of food for larvae increases with the size of the individual. Newly laid eggs need to be sorted once every 7 days or so and concentrated in the box for natural hatching. When mature larvae pupate, the pupae should be picked out in time and placed in the incubator. They should not be stacked. Adults should avoid strong light, otherwise it will affect egg laying. Yellow mealworms are less susceptible to diseases, but they must be protected from predators such as poultry, geckos, and mice.
