Embodiment 1

[0045] Select 200 chrysalis chrysalis pupae, and under the condition of 25 ℃, 189 adult chrysalis eclosions will be put into the cages equipped with pine needles according to the ratio of male to female ratio of 1:1. Each cage contains 50 adult chrysalis. First, lay eggs after 15 days, 4500 eggs are laid, the egg period is 10 days, the eggs are routinely sterilized (soaked in 10% formalin solution for 1 hour, then rinsed with clean water, and dried in the shade), at 25°C Next, 4050 hatching larvae were hatched, and the artificial feed was heated and mixed according to formula 1 in Table 1, and then packed into the feeding containers of Alchachamus larvae, and the newly hatched larvae were inserted (1 newly hatched larva was inserted into each container) After 30 days, 2,268 larvae survived, and 1,656 larvae became pupae after 310 days. The pupae continued to be placed on the feed surface, and 1,474 adults emerged after 17 days.

Embodiment 2

[0047] 180 chrysalis chrysalis pupae were selected, and 165 adult chrysalis erupted under the condition of 25°C, and the adult chrysalis monochamus were put into cages equipped with pine needles according to the ratio of male to female ratio of 1:1, and 50 adult worms were packed in each cage. First, lay eggs after 14 days, 4400 eggs are laid, the egg period is 8 days, the eggs are routinely sterilized (soaked in 10% formalin solution for 1 hour, then rinsed with clean water, and dried in the shade), at 25°C Next, 4004 hatched larvae were hatched, and the artificial feed was heated and mixed according to formula 2 in Table 1, and then packed into the larvae raising containers of Monochamus alternatus, and the newly hatched larvae were inserted (one newly hatched larva was inserted into each container) After 30 days, 2522 larvae survived, and 1992 pupae emerged after 300 days. The pupae continued to be placed on the surface of the feed, and 1793 adults emerged after 15 days.

Embodiment 3

[0049] 300 chrysalis chrysalis pupae were selected, and 278 adult chrysalis erupted under the condition of 25°C, and the adult chrysalis monochamus were put into cages equipped with pine needles according to the ratio of male to female ratio of 1:1, and 50 adult worms were packed in each cage. First, lay eggs after 12 days, 6880 eggs are laid, the egg period is 7 days, the eggs are routinely sterilized (soaked in 10% formalin solution for 1 hour, then rinsed with clean water, and dried in the shade), at 25°C Next, 6260 hatching larvae were hatched, and the artificial feed was heated and mixed according to formula 3 in Table 1, and distributed into the feeding containers of Monochamus alternatus larvae, and the newly hatched larvae were inserted (one newly hatched larva was inserted into each container) After 30 days, 4,883 larvae survived, and 4,151 larvae became pupae in 270 days. The pupae continued to be placed on the surface of the feed, and 3,736 adults emerged after 12 da...

Abstract

The invention relates to an artificial breeding and passage method of pine sawyer and a artificial diet for a larva of the pine sawyer. The method relates to: putting pine sawyer nymphae needing raising under a room temperature for being emerged into adults; then putting the emerged adults in a container provided with pine branches to mate and oviposit; disinfecting the eggs conventionally after the ovoposition; transferring the larva oviposited to a pine sawyer larva raising container provided with the artificial diet for the pine sawyer larva and raising the larva in a healthy larva raising space; in the whole process of larva raising, the foodstuff is prepared for a plurality of times until the larva is raised to be a nymphae. The artificial diet for the larva has the following components: wheat bran, soybean protein, Webster salt, cane sugar, fibrin, formaldehyde of 37 percent, Nipagin A, ascorbic acid, vitamin B12, agar, yeast, choline chloride and water.

Description

technical field [0001] The invention relates to a method for artificially raising and passing on the longhorn monochamus and its artificial feed for larvae. Background technique [0002] Monochamus alternatus, also known as Songmotianniu and Songchachamus, is distributed in Hebei, Henan, Shaanxi, Shandong, Jiangsu, Zhejiang, Jiangxi, Hunan, Guangdong, Guangxi, Fujian, Taiwan, Sichuan, Guizhou, Yunnan, and Tibet. It mainly harms the masson pine, and secondly harms the weakened trees or newly felled trees such as black pine, cedar, larch, Chinese pine, Huashan pine, Yunnan pine, Simao pine, fir, spruce, juniper, oak, corn vine, apple, and bonus fallen wood. [0003] This insect has one generation per year, with a total of 5 instar larvae. The 1st instar larvae feed on the inner bark, and the 2nd instar larvae feed on the sapwood epidermis. The moth in the xylem is about 3-4 years old. In autumn, oblate holes are drilled into the xylem for 3-4cm, and then the tunnels are bore...
