Problems solved by technology

[0004] Although the existing artificial feed for codling moth larvae can be used to establish a continuous breeding population of codling moth larvae, the scale is still small, and the weight of larvae and pupae of each age that is raised is lighter, and the larval development period is longer. The survival rate is low and the cost is high, and it is not suitable for industrialized rearing codling moth larvae, so it is imminent to provide an artificial feed for industrialized rearing codling moth larvae and its preparation method

preparation example Construction

[0015] The present invention also provides a method for preparing artificial feed for industrialized rearing codling moth larvae, comprising the following steps:

[0016] According to the raw materials and proportions of the artificial feed for industrialized rearing of codling moth larvae, the agar was weighed and put into an enamel measuring cup, water was added, and the mixture was sterilized in an autoclave.

[0017] Take out the agar and stir it with a mixer, and slowly add citric acid, malic acid, Nepal gold, yeast, soybean meal, whole wheat flour, wheat Embryo and sorbic acid are added while stirring. When the temperature drops to 60-70°C, add ascorbic acid and sucrose, mix well and pour into a clean enamel plate to cool. After cooling to room temperature, you can get apples for industrial breeding. The artificial feed for silverfish moth larvae is stored in the refrigerator for later use.

[0018] The described sterilization in the autoclave is placed, and its sterili...

Embodiment 1

[0026] 5000 codling moth pupae were placed in an incubator at 25°C, and eclosion began after 10 days. Two pairs of adults were placed in each egg-laying container to mate and lay eggs, and then the eggs produced by the mating were sterilized and hatched into larvae.

[0027] The codling moth larvae artificial diet was prepared according to formula 1 in Table 1.

[0028] Heat evenly, divide the prepared codling moth larvae artificial feed into codling moth larvae feeding plates, insert the newly hatched larvae, and put them into a healthy insect breeding room to raise them to the 4th instar, and set the room temperature at 25°C.

[0029] The hatching effect was observed and compared with that of codling moth larvae reared in the same way and with the same ratio of traditional artificial feed.

Embodiment 2

[0031] 10,000 codling moth pupae were placed in an incubator at 25°C, and eclosion began after 10 days. Two pairs of adults were placed in each oviposition container to mate and lay eggs, and then the eggs produced by the mating were sterilized and hatched into larvae.

[0032] The codling moth larvae artificial diet was prepared according to formula 2 in Table 1.

[0033] Heat evenly, divide the prepared codling moth larvae artificial feed into codling moth larvae feeding plates, insert the newly hatched larvae, and put them into a healthy insect breeding room to raise them to the 4th instar, and set the room temperature at 25°C.

[0034] The hatching effect was observed and compared with that of codling moth larvae reared in the same way and with the same ratio of traditional artificial feed.

Abstract

The invention discloses an artificial feed for factory farming of carpocapsa pomonella larvae. The artificial feed is prepared from the following components in percentage by mass: 2-10% of bean pulp, 2-4% of whole meal, 1-3% of cane sugar, 2-5% of yeast, 4-8% of wheat germ, 1.2-1.8% of agar, 0.2-0.4% of citric acid, 0.2-0.5% of malic acid, 0.3-0.6% of ascorbic acid, 0.2-0.6% of sorbic acid, 0.1-0.5% of nipagin and 65-87% of water. The invention also discloses a preparation method of the artificial feed for factory farming of carpocapsa pomonella larvae. The artificial feed for factory farming of carpocapsa pomonella larvae and the preparation method belong to the technical field of insect farming; the prepared artificial feed for carpocapsa pomonella larvae is rich in nutrition, simple and convenient to prepare, low in price, low in cost, can be applied to large-scale farming of carpocapsa pomonella larvae and is remarkable in effect, and the preparation method is time-saving and labor-saving.

Description

technical field [0001] The invention belongs to the field of insect breeding, and in particular relates to an artificial feed for industrially raising codling moth larvae and a preparation method thereof. Background technique [0002] Codling moth (Cydiapomonella L.) belongs to Lepidoptera, Lepidopteridae, Cydiapomonellae subfamily. It is widely distributed in all continents of the world. It mainly harms apples, pears, sand fruits, peaches, apricots and other fruit trees. It is one of the worldwide fruit-boring pests. First, its hazards are devastating, and it is listed as an international quarantine object. The codling moth is native to southern Eurasia, and its original host was wild apple trees. Later, it began to harm apple cultivars, and expanded its suitable range with the expansion of apple cultivars. Since the discovery of codling moth in Xinjiang, my country in the late 1950s, it has been causing epidemics in Xinjiang year after year. Since the codling moth was in...
