Problems solved by technology

Although the artificial feed reported by the public is effective, it generally has the following disadvantages: (1) the feed viscosity is large, it is easy to produce mildew spots, and the feed needs to be replaced many times, which is time-consuming and labor-intensive, and it is easy to cause the survival rate of larvae and the decline of pupation rate. High pupal rate
(2) Nutrition is not balanced enough, adults are prone to deformed wings, and the population will degenerate after multiple generations of feeding
(3) Using manual stirring of the feed mixture is not only laborious but also uneven, so that the nutrients cannot be fully mixed, and the growth of the larvae is uneven.
The above-mentioned feeding method has the following disadvantages: (1) feeding with an ins

Embodiment 1

[0042] Embodiment 1 (preparation 735g artificial feed)

[0043] Wheat bran: 30g; ash vegetable powder: 20g; corn flour: 10g; casein: 20g; cooked soybean powder: 20g; yeast powder: 15g; agar powder: 11g; distilled water: 600ml; cholesterol: 0.45g; soybean edible oil: 2.1 ml; Ascorbic acid: 4.2 g; Methylparaben: 1.75 g; Sorbic acid: 0.84 g.

Embodiment 2

[0044] Embodiment 2 feed preparation method:

[0045] During the implementation process, the homogenizer was soaked in 400mg / L chlorine water for 20 minutes for disinfection to prevent the feed from being infected with bacteria during the preparation process.

[0046] (1) Preparation of cooked soybean powder: buy high-quality soybeans from the market, bake them in an oven at 120°C for 2 hours, then grind them in a grinder, and grind them as finely as possible, then put the ground soybean powder on homemade kraft paper Sterilize the bag in a high-temperature humid heat sterilization pot for 1.5 hours, crush the sterilized bean cakes on newspaper, spread them evenly to dry, and put them back into kraft paper bags, label them and place them in a 5°C refrigerator Save for later use;

[0047] (2) Preparation of gray vegetable powder: wash the fresh gray vegetable leaves, dry them in an oven after drying naturally in the sun, then crush them through a 90-mesh sieve, take the leaf p...

Embodiment 3

[0055] Implement the large-scale, long-term, subculture raising method of example 3 beet armyworm

[0056] The environmental conditions in the insect culture room for the artificial rearing of beet armyworm are as follows: the temperature is 27±1°C, the indoor relative humidity is 40%-50%, and the photoperiod is L14:D10. Under the irradiation for 2 hours, spray disinfection with 400mg / L disinfectant for 20 minutes, and open the window of the insect breeding room to ventilate once every 3 days. During the breeding process, also pay attention to the cleanliness and cleanliness of the room. If there are worms infected with bacteria or viruses in the middle, they should be cleaned out of the insect breeding room in time. Before raising insects, small brushes, tweezers, scissors, small spoons, etc. used for insect rearing should be sterilized by high temperature and humidity, and the brushes used should be as soft as possible.

Abstract

The invention relates to an artificial feed for asparagus caterpillar, preparation of the artificial feed and a feeding method, and belongs to the field of insect feeds. The artificial feed for asparagus caterpillar comprises the following components: wheat bran, chenopodium album powder, corn flour, ripe soybean powder, yeast powder, agar powder, distilled water, cholesterol, soybean edible oil, ascorbic acid, methyl parahydroxybenzoats and sorbic acid. Raw materials used for the feed are easy to obtain; the preparation technology is simple; the cost is relatively low; the guarantee period is relatively long (6 months); chenopodium album can reduce the viscosity of the feed, enhance the survival rate and percentage of pupation of larvae, can reduce the abnormal pupa rate, and can provide various vitamins required for the development of larva, so that the fed asparagus caterpillar has the average pupal weight of 111.8mg, has the average moth weight of 100.4mg, has the larva survival rate of 91%, and has the eclosion rate of 98%; the pupas have strong vitality, and can be stored in a refrigerator with the temperature of 5 DEG C for 7 days; the feed is relatively good in feeding effect and achieves the aim of long-term large-scale continuous rearing.

Description

technical field [0001] The invention relates to insect feed and feeding technology, in particular to artificial feed for beet armyworm, its preparation method and feeding method using the feed. Background technique [0002] Beet armyworm spodoptera exigua It belongs to Lepidoptera of Lepidoptera and Noctuidae of family Noctuidae. It is a kind of pest with miscellaneous feeding habits and strong drug resistance, which often poses a serious threat to agricultural production and economy. In my country, before the 1980s, the beet armyworm mainly caused damage to Beijing, Hebei, Henan, Shandong and Shaanxi. Although it was distributed in the northeast, northwest and the Yangtze River Basin, the damage was not serious. Since the mid-to-late 1980s, the area infested by beet armyworm has gradually expanded, the scope of damage has become larger and larger, and the economic losses caused have become more and more serious (Yu Yousen et al., 1989; Jiang Xingfu, 1998; Song Guochun, 19...
