1. Select fields: When cultivating beanworms, you need to choose well-drained and sunny land as the breeding field, and then apply decomposed organic fertilizer to the breeding field. 2. Collect larvae: capture healthy larvae without pesticide contamination from soybean fields in the wild, and then put them into breeding fields. 3. Pupate and lay eggs: Bean bugs will pupate in the soil from May to June every year. At this time, soybeans need to be planted again in the breeding fields.

1. How to raise beanworms and where to buy larvae

1. Choose a field

(1) When cultivating beanworms, be sure to choose a field with good drainage and a sunny location Use the land as a breeding field, and then apply some decomposed organic fertilizer to the breeding field.

(2) Generally, soybeans can be planted in the breeding fields in late June every year. After planting, the fields must be surrounded by iron fences or wooden fences.

2. Collect larvae

(1) Be sure to capture healthy larvae that are not contaminated by pesticides from soybean fields in the wild, and then put them into Breeding fields.

(2) Generally, in September every year, bean bugs will sneak into the roots of soybeans to overwinter, so soybeans must be harvested in October. During harvesting, the soil must not be plowed to avoid damaging the beans. insect.

3. Pupation and egg laying

(1) Bean beetles usually pupate around May-June every year, and must be placed in the breeding field at this time. Plant soybeans again to provide food for the bean bugs.

(2) From late June to early August, bean bugs will hatch into bean hornworms and then lay eggs on the surface of soybean leaves. Each female moth can lay about 200-300 eggs.

4. Feeding method

(1) When raising bean worms, you must wait for the eggs to hatch before placing the newly born larvae indoors for raising. , be sure to choose a greenhouse or bungalow with good ventilation as a breeding place.

(2) Put a wooden box or carton into the breeding place, then place the beanworms in the box and feed the beanworms 1-2 soybean leaves every day.

2. Where to buy larvae

1. Bean worms can be purchased at places that specialize in hatching larvae. When the temperature rises in April, bean beetles will pupate in the soil. During the pupation period, soybeans must be replanted. Adult beetles will emerge in June and then start laying eggs. Eggs are generally laid on the back of soybean leaves, and adults will start laying eggs 3 hours after mating. During this period, flight away must be prevented.

2. Soybeans must be planted before the bean beetles pupate. The larvae in a 9-square-meter breeding field require 1 or 2 acres of bean leaves for feeding during the entire larval stage. The hatched larvae can be raised indoors, just like silkworms. They are raised in separate pools. The pools are covered with gauze to prevent escape. Fresh bean leaves can be picked and spread to feed. Feeding leaves increases as the larvae age.

3. By September, you need to select strong mature larvae and put them in the breeding field to let them survive the winter. Then they will pupate and emerge in the next year, mate and lay eggs to hatch out new larvae. This is to save insect seeds for next year, and you need to save seeds like this every year in the future.
