Embodiment 1

[0026] Embodiment 1: (rice leaf roller artificial feed preparation 1)

[0027] The dosage of each component in this example is: casein 3.75g, wheat germ powder 2.5g, sorbic acid 0.2g, sucrose 1.25g, glucose 2.5g, agar 1.5g, 4M KOH 0.3g, vitamin C 0.4g, vitamin E 0.02g , complex vitamin B 0.02g, water 100g, rice leaf dry powder 3g. The rice leaf roller artificial feed is prepared according to the following steps:

[0028] (1) Heat casein, 4M KOH and 30ml water to 90°C to dissolve casein.

[0029] (2) Soak dry rice leaf powder in 30ml of water for 30min, bathe in 80°C water for 10min, add agar and add 2.5ml of water, heat to dissolve the agar.

[0030] (3) Mix the solutions of (1) and (2), and add wheat germ powder, glucose, and sucrose in sequence, and then stir and mix thoroughly.

[0031] (4) When the temperature of the mixed solution (3) drops to 50-60°C, add complex vitamin B, vitamin C, vitamin E, and sorbic acid in sequence, and after fully stirring, pour it into a ste...

Embodiment 2

[0032] Embodiment 2: (rice leaf roller artificial feed preparation 2)

[0033] The dosage of each component in this example is: casein 2g, yeast powder 2g, wheat germ powder 2.5g, sorbic acid 0.16g, paraben 0.16g, sucrose 1g, glucose 2g, agar 2g, cellulose 1g, 4MKOH 0.3g, Vitamin C 0.4g, vitamin E 0.02g, vitamin B complex 0.02g, water 100g, rice leaf dry powder 2.5g. According to the steps of Example 1, the artificial feed for rice leaf rollers is prepared.

Embodiment 3

[0034] Embodiment 3: (artificial rearing of rice leaf roller larvae)

[0035] The artificial feed prepared in Example 1 and Example 2 combined with the leaves of corn seedlings were used to feed the larvae of the rice leaf roller, while the leaves of corn seedlings were fed alone as a control. Specifically follow the steps below:

[0036] (1) Cultivation of tender corn seedlings: Soak mature corn seeds for 24 hours and cover with wet cloth to accelerate germination. Put the white corn seeds in the germination box to germinate and grow in the light incubator at 25°C, and obtain the desired tender corn seedlings after 5-8 days.

[0037] (2) Move the corn leaves with the newly hatched rice leaf roller larvae into a 9cm-diameter plastic petri dish, add fresh corn seedling leaves, put wet cotton balls in the dish to moisturize, and place them in a biochemical laboratory at 25°C and a relative humidity of 95%. Raise in the incubator, inoculate 100 worms per dish, and replace fresh...

Abstract

The invention discloses a formulation of an artificial feed for cnaphalocrocis medinalis guenee, a method for preparing the same and a method for breeding the cnaphalocrocis medinalis guenee, which belongs to the technical field of insect feed and breeding. The formulation of the feed comprises the following components in portion by weight: 2 to 4 portions of casein, 0 to 4 portions of yeast powder, 1.5 to 3 portions of glucose, 0.5 to 2 portions of cane sugar, 2 to 5 portions of wheat-germ powder, 0.01 to 0.02 portion of vitamin B complex, 0.2 to 0.4 portion of vitamin C, 0.01 to 0.02 portion of vitamin E, 1 to 4 portions of agar, 0 to 2 portions of cellulose, 2 to 4 portions of rice leaf dry powder (which is prepared from rice leaves of tillering stage by drying and crushing at a temperature of 60 DEG C), 0.2 to 0.4 portion of 4M potassium hydroxide, 0.1 to 0.2 portion of sorbic acid, 0 to 0.2 portion of nipalgin, and 90 to 120 portions of water. The feed is prepared simply with low cost, and is favorable for the cnaphalocrocis medinalis guenee which has normal growth and development, thereby overcoming the difficulty that the cnaphalocrocis medinalis guenee cannot be bred for a successive generation artificially, achieving the artificial scale breeding of insects, and providing a material and a method for scientific experiments, chemical medicament screening and the production of a viral pesticide.

Description

technical field [0001] The invention relates to the technical field of insect feed and feeding, in particular to the preparation of artificial feed for the rice leaf roller and the artificial feeding method for subculture of the rice leaf roller. Background technique [0002] Rice leaf roller (rice leaf roller), alias scraper caterpillar, leaf roller, white leaf worm, etc., belongs to Lepidopwera (Lepidopwera), Moth family (Pyarlidae), is an important migratory insect that damages rice in my country. sexual pests. The larvae roll the leaves vertically to eat and cause damage, leaving only the epidermis and forming white streaks, which affect the photosynthesis of crops. In the middle and late stages of rice, it will damage the upper functional leaves and affect the filling, resulting in unfulfilled seeds, increased hollow rate, and reduced thousand-grain weight. Generally, the yield can be reduced by 20-30%, and the heavy one is more than 50%. No grain harvest. Since 2000,...
