Description

An incubator for sand crawling worm eggs

technical field

The utility model relates to an insect hatching device, in particular to an egg mass hatching tool for sand crawling insects.

Background technique

Sand crawling worm is a common name for insects of the family Insecta Pteroptera, and it is called "animal ginseng". It has extremely high medicinal and edible value, and is a resource insect with high promotion value. In the existing hatching technology of sand crawling insect eggs, it has basically got rid of the simple and extensive hatching method and has made great progress. Especially on October 5, 2011, the utility model patent "Sand Climbing Worm Egg Incubator" invented by Cao Chengquan and others made a big breakthrough in the egg hatching method of sand crawling worms. The box includes an egg hatching shell with a partition, a suspended dense gauze, a water outlet switch, and a shell cover that is clamped with the shell of the incubator. The incubator is light and compact, has multiple hatching spaces, has the advantages of preventing eggs from being parasitized, being convenient for observation and adding water during the hatching process of sand crawling insect eggs, and can also artificially control temperature, light and other conditions, and has a good effect on first-instar larvae. Certain protection can be kept intact and safe.

Although the above-mentioned sand crawling worm egg incubator has made breakthroughs, and has certain guarantees for the hatching efficiency of sand crawling worm eggs and the survival of newly hatched larvae, in actual operation, there are still the following deficiencies:

1. Place the egg mass directly on the suspended dense gauze net. Only by spraying water, the humidity of the egg mass cannot be guaranteed for a long time, which affects the hatching rate of the egg mass; 2. Although the upper half of the incubator shell uses gauze net, the ventilation is still Not enough, when the humidity is too high and the temperature is too high, the egg mass is prone to mold and mold, which affects the hatching rate; 3. Most of the first-instar larvae of sand crawling worms are concentrated in a small space after hatching, and cannot be isolated and dispersed in time. The phenomenon of clumping and cannibalism occurs, which reduces the survival rate of the first instar larvae; 4. The appliance is not equipped with a water pipe, which makes it inconvenient to change water and feed food for the first instar larvae, which cannot achieve high efficiency and automation, and affects the survival of the first instar larvae Five, this utensil discharges water on the arc-shaped bottom edge of the housing bottom, because the bottom edge is longer, the transfer work of the first instar larvae is loaded down with trivial details and difficult.

Utility model content
