The cultivation of mealworms should be paid attention to in many details, otherwise it will cause a large number of deaths. To summarize the causes of the death of yellow powder and some common wrong practices in aquaculture.
<h1 class= "pgc-h-arrow-right" > the basic techniques of mealworm farming, such as temperature and humidity management, feed nutrition, disease prevention and natural enemies, etc., have been mentioned in yesterday's article, you can go to see yesterday's article for yourself. </h1>
Raising mealworms well requires paying attention to five important aspects such as temperature and humidity control and feed nutrition
Healthy and active mealworms
<h1 class="pgc-h-arrow-right" > mealworms are not properly managed during hibernation and can cause mealworms to die</h1>
1. Low temperature causes the death of mealworms
In the four changes of mealworm, only the larvae of mealworm (that is, we call it mealworm) can hibernate, and the pupae, adult worms and eggs of mealworm cannot hibernate. During the hibernation of the yellow mealworm, if the temperature is below 0 ° C, the yellow mealworm will suffer frostbite and die.
2. Lack of feed causes the death of mealworms
Mealworms are theoretically below 10 ° C into hibernation, and in actual breeding, it is found that mealworms eat above 5 ° C (when the yellow mealworms have slight activity), so the yellow mealworms should be placed in wheat bran to hibernate. If wheat bran is missing, mealworms will bite each other, resulting in death.
3. Mealworms are eaten by rats
During the hibernation of the yellow mealworm, due to the infrequent entry of people in the breeding room, due to neglect management, there will be a phenomenon of the yellow mealworm being eaten by rats, and the yellow mealworm should prevent rats during hibernation.
Processed mealworms
<h1 class="pgc-h-arrow-right" > during the summer heat season, some mismanagement can cause mealworms to die</h1>
1. High temperature directly leads to the death of mealworms
When the temperature is higher than 35 ° C, it will directly lead to the death of the mealworm, and if the high temperature weather cannot cool down, the mealworm will be transferred to a place with a low temperature (it can no longer rely on methods such as insect droppings to cool down).
2. Open the fan to cool down in high temperature weather
Some people in high temperature weather, do not transfer the yellow mealworm in time, just open the fan in the breeding room to cool the yellow mealworm, the fan can not play a cooling role on the yellow mealworm. Mealworm is a warm animal, and we humans are not the same, when people are hot, through the fan to speed up the evaporation of sweat, play a cooling on the surface of the body, there is a cool feeling. In the summer high temperature weather, no matter how to open the fan in the breeding room, the temperature will not be reduced, and the blowing wind will also cause damage to the yellow mealworm.
3. Spray water in summer to cool down
In the summer heat, spraying water on the yellow mealworm or spraying water into the wheat bran in the breeding box will lead to the death of the yellow mealworm, which was also mentioned in yesterday's article.
4. Feed the yellow mealworm wet wheat bran in summer
In the hot summer weather, some people mix wheat bran wet with water to feed the yellow mealworms, and this method is also wrong. Regardless of the season, it is not recommended to feed wet wheat bran. Wet wheat bran in summer not only causes bugs to die, but also quickly deteriorates in high temperatures. Note: the difference between damp and wet (more than 20% of the water content is wet), dry weather mixed with chopped vegetables of the tide bran can be fed; the way to distinguish between wet and wet, is to grab a handful of bran with your hand and hold it tightly, let go of the hand to see if the bran can spread out on its own.
Adults of mealworms, commonly known as beetles
<h1 class="pgc-h-arrow-right" > the wet and rainy summer season, and if not properly managed, mealworms can easily die</h1>
1. Open the window for ventilation during the rainy season
During the rainy summer season, due to the humidity in the breeding house, it can lead to black rot and mite disease of mealworms. At this time, some people will open the window for ventilation, but if the air humidity outside is greater than in the breeding room, the window ventilation can only play the opposite role. Rainy weather will generally be lower temperature, the correct way is to close the doors and windows, with electric heating fans and other heating, dry the air in the breeding room. Note: When the heating is just added, the air humidity will suddenly become larger, and the humidity will drop after continuing to heat up (it is a reason that the car will fog when the hot air is just turned on).
2. The summer rainy season causes wheat bran to become moldy
In the rainy summer, whether it is wheat bran added to the breeding box or stored in the bag, if there is mold, it will cause the death of the yellow mealworm. In the summer rainy season, attention should be paid to the combination of drugs to prevent the Black Death, commonly used drugs are oxytetracycline, chlortetracycline, chloramphenicol, and the proportion added to wheat bran is 0.1%. At the same time, it can be added to prevent the indigestion of mealworms by adding mother-eating (yeast flakes), and the proportion of addition is also 0.1%.
3. In rainy weather, you cannot feed vegetables to mealworms
In rainy weather, the breeding room is already humid, and then add greens to the feed of the yellow mealworm, which will cause the yellow mealworm to die of illness due to excessive moisture, so when the air humidity in the breeding room is greater than 80%, the yellow mealworm cannot be fed vegetables.
Daily management of mealworm farming
<h1 class="pgc-h-arrow-right" > the collective temperature generated by the friction between the mealworms, which will cause the mealworms to die at high temperatures</h1>
The yellow mealworms in the breeding box rub against each other, which will produce local high temperature inside, such as the actual air temperature in the breeding room is 30 ° C (the temperature shown in the temperature table), but because the density of the yellow mealworm in the yellow mealworm breeding box is too large, the hand will feel hot inside the yellow mealworm, then the actual temperature of the yellow mealworm may reach close to 40 ° C, and this internal high temperature is called the collective temperature.
The cultivation of mealworms should prevent the collective temperature from being too high and causing death, and generally pay attention to the occurrence of collective high temperature when it is above 25 ° C. To avoid the collective temperature is too high, the density of mealworms should be reduced, and the yellow mealworms in the summer breeding box should not be higher than 2 cm; at the same time, the box should be appropriately left with insect feces, and the insect feces should be used to cool down.
A mealworm that is about to pupate
<h1 class= "pgc-h-arrow-right" > the method of supplementing vegetables with mealworms is incorrect, but it will cause the death of mealworms</h1>
1. After cleaning the leaves, dry them and feed them to the yellow mealworms
It is said above that in rainy weather when the humidity is too large, you can not feed vegetables to the yellow mealworm; you can supplement the vegetables when the air humidity is less than 70% ; and you must feed the yellow mealworm vegetables when it is too dry.
When feeding the leaves to the yellow mealworm, if it is a green vegetable bought from the market, in order to prevent the spraying of pesticides, be sure to soak and wash it before feeding the yellow mealworm. After soaking, it should not be sprinkled directly into the breeding box with water, it should be dried and fed, otherwise it is too humid, which will also cause the death of the yellow mealworm.
2, can not give mealworms only vegetables
Vegetables are only used as supplementary feed for mealworms, when feeding vegetables to yellow mealworms, either chopped and mixed with wheat bran to feed to yellow mealworms, or yellow mealworm breeding box must have a layer of wheat bran, can not be eaten in the absence of wheat bran, eat to feed vegetables to yellow mealworms. For example, some people say that there is no wheat bran in these few days, and they are afraid of hungry yellow mealworms, so let the yellow powderworms eat vegetables first, so it is not OKAY, the yellow powderworms only eat green vegetables and do not eat wheat bran, the same will cause death due to excessive absorption of water.
3. Mealworms should be fed vegetables in an appropriate amount
The amount of vegetables supplemented with mealworms should be reasonable to prevent the death of mealworms caused by feeding too many vegetables. In the summer, it is also necessary to prevent too many supplementary vegetables, yellow mealworms cannot eat, and vegetables are moldy and deteriorated in the breeding box. It is advisable to add one or two vegetables per kilogram of yellow mealworms every day, and from the time point of view, the vegetables thrown into the breeding box can be eaten by the insects in 3-4 hours.
Mealworms are fed vegetables
4. The vegetables fed to the yellow mealworm should be chopped
Feeding the green leaves to the yellow mealworm can be evenly sprinkled in the breeding box, when feeding pumpkin, carrot, watermelon peel and other large pieces of feed, it should be chopped and then evenly sprinkled in the yellow mealworm, or chopped and mixed with wheat bran to feed the yellow mealworm. For example, some people directly throw a whole piece of watermelon peel directly into the yellow mealworm box, so that not only will some yellow powderworms die due to eating too much, but also some yellow mealworms will not be able to eat.
5. When feeding vegetables, prevent vegetables from sticking to insect droppings
When feeding vegetables to mealworms (especially pumpkins, carrots, etc., with large water content), ensure that there is a layer of wheat bran between the insect manure and the vegetables. Either sprinkle wheat bran first and then feed vegetables, or after sifting the insect manure, and then feed the wheat bran mixed with vegetables to the yellow mealworm to prevent the vegetables from staining the insect manure, which is easy to contaminate the feed and easily cause the yellow mealworm to get sick and die.
The above summarizes with you some of the wrong management methods that are easy to cause the death of mealworms in the process of mealworm breeding, and it is also some practical experience summarized in my cultivation of mealworms.
