For a long time, the larvae are difficult to peel off, and they are prone to cause common diseases of sudden death. Therefore, in the breeding practice, the following points will increase the survival rate of the larvae.
First, create a suitable environment. The first time the larvae were born, the time of first peeling was relatively concentrated, usually about 5 hours, and the time from the second peeling was inconsistent. The peeling occurred once every 40 days, such as improper management methods, lack of food, single feed or The structure of armpits is unreasonable, etc., which can cause slaughter or detachment and physiological death. Therefore, when cubs are peeled, the density of 2-3 instars should be less than 3,000 per cubic meter, and the gap between brick layers should not be too large. Between 15 cm, some gravel or weathered clods should be placed in the armpits to help the mechanical peeling of the dumplings. In addition, special attention should be paid to the nutritional combination of wolfberry fruit. In addition to feeding high-quantity protein insects, some soil worms and terracotta must be fed.
Second, create a suitable temperature. Scorpion peeling process like moderate temperature, high humidity environment, such as the appropriate temperature and humidity, the total peeling process of about 2-5 hours of wolfberry; if the temperature and humidity is not appropriate, the time will be extended or died halfway. When peeling the young, the daily average temperature is required to be between 25 and 35 degrees Celsius. The soil temperature in the armpits should be between 10 and 15 degrees Celsius, and the relative air humidity should be about 75%.
