CATDOLL : CATDOLL: How long does it take for mealworms to transform from larvae into insects?

1. How long does it take for mealworms to transform from larvae into insects?

The optimum temperature for the growth and development of mealworms is 25-28℃ and the relative humidity is 50-70%. Indoor heating in winter and cooling by sprinkling water on the ground in summer can ensure their normal growth and development. For raising mealworms, you can choose to use concentrated feeds such as bran, rice bran, fish meal, and green feeds such as vegetable leaves and melon peels.

1. Adults and eggs. After the pupae emerge into adults in the box, remove the waste and pupal skins in the box in time. When adding green fodder to feed the adults, you can add some fresh concentrate. The adults begin to lay eggs 3-6 days after they emerge. At this time, spread white paper on the bottom of the box, and then spread a small amount of green fodder, and let the adults lay eggs on the paper. After laying eggs, take the eggs every 2-5 days (replace once a day during the peak egg-laying period) and replace them with new white paper. After each egg collection, add green fodder and concentrate to the adults appropriately.

2. Larvae. After the newly hatched larvae are moved to the insect box, a thin layer of sterilized bran is immediately sprinkled in. As the larvae molt and grow, gradually increase the amount of concentrate and green feed. When the larvae molt, feed less or no feed. The daily feed amount is based on the feed in the box eaten up at night. Feed enough in the morning and evening, and supplement at noon. In the early stage, concentrate feed is the main feed, supplemented by green feed; in the later stage, green feed is the main feed, supplemented by concentrate feed. Some old larvae have a poor appetite after the peak pupation period. At this time, some fish meal can be added to promote uniform pupation. Clean the insect feces every 15 days, and clean it every 7 days in the middle and late stages. Use a sieve to sift out the insect feces. Do not feed for half a day before cleaning the feces. When the larvae are of different sizes due to different growth rates, they should be raised in boxes according to size. One box can raise 10,000-15,000 young larvae and 6,000-8,000 old larvae.

3. Pupa. The larvae begin to pupate after molting 8-15 times. Before pupation, pay attention to feeding more green feed to facilitate pupation and subsequent pupal emergence. Pick the newly emerged pupae into another box in time every day and sprinkle a layer of fine feed on them, so as not to cover the pupae.

2. There are wasps at home. Ask some related questions and seek help

I still advise you to get rid of them as soon as possible... Don't think of any perfect preventive measures, leaving a landmine at home. When the wasp attacks, if there is nothing to protect you, remember to protect your eyes. ---Speaking from experience, it's okay to be stung in other parts of the body, but it's really uncomfortable to be stung in the eyes. If you really want to cover yourself, you can take a hat with a larger brim and sew a mosquito net on the edge. The mosquito net should cover your neck, and sew a rope at the bottom to tighten it (tie it to the collar of your neck), and wear it when committing a crime. Wear thicker long sleeves, rubber gloves, long pants, cloth shoes, and seal all holes. If you do the above, you can basically resist the attack of wasps with average attack power. After being stung, pull out the wasp's stinger and throw it in a safe place (the pulled out stinger can still sting people). Wash with vinegar, or if there is no vinegar, use local materials, and your own urine will also work. --- Bee venom is acidic and can be neutralized with alkaline liquid. In severe cases, please seek medical attention immediately. It is best to commit the crime at night!

3. In which month are wasp pupae the most abundant?

It varies from region to region. Low altitude tropical areas harvest in August or September, while cold areas harvest in September or October. In our area, yellow scallops are usually harvested during the Mid-Autumn Festival.

IV. About the Wasp in "Insect Life"

Although "The Insect World" is a work by the famous French entomologist Fabre, due to limitations in technical conditions, historical background and translation issues, there are more or less errors in the book. This passage may be one of them.

In winter, most of the worker bees in the hive will die, but the drones and some of the worker bees will still survive. There is no such thing as "total annihilation".

More importantly, even if all the worker bees and eggs die, as long as there is a queen bee that can mate with the drones, new eggs will be laid and the bee colony will not perish. Even if the hive is hit hard by low temperatures in winter, the queen bee will survive under the protection of all the worker bees in the hive, and the hive will still thrive the following year.

The error caused by some reasons leads to the paradox that all the bee colonies will die in winter, which is actually impossible.

5. What are the characteristics of insect bumblebees?

The main characteristics of insects are that their bodies are segmented and divided, and they generally have three pairs of legs and two pairs of wings. The body of an insect is divided into three parts: head, thorax and abdomen. There is an exoskeleton on the surface of the body, which can play a role in protection and support. Insects have three pairs of legs on their thorax, and the hind legs are well developed and suitable for jumping.
