1. How does dracunculiasis breed?
1. Prepare 40 glass test tubes or disposable plastic test tubes, put a small amount of wheat bran at the bottom of the test tubes, then put 40 barley worm larvae at the bottom of the test tubes respectively, and move the test tubes to the shade.
2. Take out the larva after it curls up, transfer it to the pupation tank, and then continue to replenish a larva in the empty test tube.
3. After about 7 days, wait until the curled larvae become pupae, then pick out the pupae and put them in the container.
4. After pupae emerge into adults, they are transferred to grasshopper cages for feeding. The bottom of the cage is covered with more than 2 cm of wheat bran, and at the same time, a proper amount of vegetable leaves are fed.
5. Adults lay eggs in cages, and the eggs fall on the wheat bran below.
After 6, 2-3 weeks, the eggs hatch into larvae. At this time, a proper amount of concentrated feed and pericarp are added for the larvae to eat and eventually grow into barley worms.
Second, wheat breeding technology
1, larval feeding management
(1) Before feeding, put feed such as bran (which needs to be screened with gauze) into the feeding box or feeding box, and then put the dracunculiasis larvae. The density is based on the fact that the larvae are all over the feeding box, and the thickness is not more than 3-5cm.
(2) Spread a proper amount of vegetable leaves evenly on the worms, and let the dracunculiasis larvae eat (at the end of the larvae, feed more vegetables, and some older larvae have poor appetite and need to feed a proper amount of fish meal).
(3) Clean up the insect manure once every 7 days or so.
2. Pupa management
(1) Pick out the larvae that are about to pupate (mainly manifested as inactivity, crouching and poor skin luster) and put them in a feeding basin for feeding.
(2) Pick out pupae after pupation, put them into different eclosion boxes according to different days, and lay coarse chaff with the thickness of 1cm at the bottom of the boxes.
(2) In the pupa stage, it is necessary to adjust the temperature and humidity to prevent the insect pupa from becoming moldy. The suitable temperature for pupa emergence is 25-30℃ and the suitable humidity is 65-75%.
(3) After about 10- 13 days, the pupae emerged as adults.
3. Adult feeding management
(1) The adult male-female ratio is about 1: 1, and it is 1000- 1200 per square meter.
(2) The adults began to lay eggs about 6- 1 1 day after emergence, and entered the peak spawning period about 1-2 months after emergence, and were fed 1-2 times a day (wheat bran with a thickness of 1cm was sprinkled on the bottom, and then mixed with chopped vegetables).
4. Egg management
(1) Put white paper on the feeding basin, sprinkle a layer of bran on the paper, and then place the spawning sieve. When an adult lays eggs, the eggs pass through the mesh of the iron net and land on the bran.
(2) White paper for catching eggs should be replaced once every three days, and once a day if it is in spawning season.
(3) Put the eggs collected that day into the same larval box, and after 7- 10 days, the larvae hatch out.
