Embodiment 1

[0044] Weigh 3g of rice leaf powder, 8g of wheat germ powder, 4g of corn flour, 3g of soybean powder, 3g of casein, 6g of granulated sugar, 2.3g of agar, 30mg of Westerman’s salt, and 40mg of cholesterol into a 250mL beaker, add water, mix well, and soak After 30 minutes, heat in a microwave oven (heating for 3 minutes in total) to completely dissolve the agar, mix well, and cool to 55°C. Finally, add 5g of yeast, 0.25g of ascorbic acid, 0.01-0.3g of antifungal agent, 0.3mL of water bran oil, 50mg of choline chloride, 40mg of streptomycin, and 3mg of Fannin's vitamins. and then ready to use.

[0045] Embodiment 2: Sorbic acid is to the inhibition of Aspergillus flavus and Aspergillus niger

Embodiment 2

[0046] Prepare artificial feed by the method for embodiment 1, use sorbic acid as antifungal agent when adding antifungal agent, make the concentration of sorbic acid in the artificial feed be respectively: 500ppm, 750ppm, 1000ppm, 1500ppm, 2000ppm. Experimental observation method is the same as embodiment 2. The inhibitory effect of sorbic acid on the growth of Aspergillus flavus and Aspergillus niger figure 1 , In addition to the poor inhibitory effect on mold at the lowest concentration of 500ppm, the antifungal effects of other treatment concentrations are very good, and 750ppm can effectively control the growth of Aspergillus flavus and Aspergillus niger.

[0047] Embodiment 3: Natamycin is to the inhibition of Aspergillus flavus and Aspergillus niger

Embodiment 3

[0048] Prepare artificial feed according to the method of embodiment 1, use natamycin as antifungal agent when adding antifungal agent, make the concentration of natamycin in artificial feed be respectively: 25ppm, 50ppm, 100ppm, 200ppm, 300ppm, test Observation method is the same as embodiment 2. The inhibitory effect of natamycin on the growth of Aspergillus flavus and Aspergillus niger figure 2 100ppm and 200ppm have certain inhibitory effects on Aspergillus flavus and Aspergillus niger, and 300ppm can still completely inhibit the growth of Aspergillus flavus on the 20th day, but the inhibitory effect on Aspergillus niger is slightly worse.

[0049] Embodiment 4: the inhibitory action of sodium benzoate to Aspergillus flavus and Aspergillus niger

Abstract

The invention relates to an artificial feed of a rice leaf folder and a preparation method of the artificial feed. The artificial feed belongs to the technical field of insect raising. The formula is prepared from the following components of water, rice leaf powder, wheat germ powder, corn meal, soybean meal, casein, granulated sugar, agar, yeast, mildew inhibitor, antioxidant, insect feed oil, antibiotic, choline chloride, wade-salt, cholesterol and vitamine. The mildew inhibitor used in the formula is composed of 2-3 of natamycin, sorbic acid, nipagin, tebuconazole and azoxystrobin; the antioxidant is mixture of ascorbic acid and phospholipid; the insect feed oil is the mixture of linseed oil, rice bran oil and germ oil, and the antibiotic may be streptomycin or chloramphenicol or aureomycin. Survival rates of larvas can be obviously improved by raising the rice leaf folder by the feed in the formula, and a foundation is created for an indoor research of the rice leaf folder.

Description

technical field [0001] The invention belongs to the technical field of insect feeding, and relates to an artificial feed formulation for rice leaf rollers, in particular to the formulation of a compound antifungal agent in the artificial feed, the use of antioxidants and a feed preparation method. Background technique [0002] The production of crops often causes huge economic losses due to the damage of agricultural pests. It is necessary to control important agricultural pests to recover the economic losses caused. Therefore, it is necessary to conduct in-depth research on the occurrence rules, conditions and control technologies of agricultural pests. The research on insects requires large-scale breeding of insects indoors to provide research materials for experiments, and feeding insects with artificial feed is the most basic work in these research work. At present, many agricultural pests can be continuously subcultured on a large scale indoors, such as cotton bollworm,...
