Problems solved by technology

[0003] The research on artificial feed for tea geometrids involves two documents and two patents, but tea powder is used in both documents and patents. The quality of tea powder seriously restricts the quality and stability of tea geometrid breeding, and it is difficult to scale breeding tea inchworm

Embodiment 1

[0070] An artificial feed capable of being suitable for large-scale cultivation of tea inchworms is made of the following raw materials in parts by weight:

[0071] Raw material parts by weight

[0072] Agar (food grade) 2.2

[0073] Potassium sorbate (analytical pure) 0.07

[0074] Butylparaben (analytical pure) 0.46

[0075] Casein 2.1

[0076] Vitamin C 0.44

[0077] Multivitamin 1.3

[0078] Defatted soy flour 1.5

[0079] elderberry powder 11

[0080] malt powder 8

[0081] Water makes up 100

[0082] A method for preparing artificial feed for large-scale cultivation of tea geometrids, the steps of which are:

[0083] 1. Weigh agar, potassium sorbate, butylparaben, casein, vitamin C, multivitamins, defatted soybean powder, elderberry powder, malt powder, and water in a certain proportion, and set aside;

[0084] 2. Heat the agar with purified water (agar: water = 1:20) to 80 or 85 or 89 or 94 or 97 or 100 ℃ to dissolve, cool to 60 or 62 or 64 or 66 or 68 or 70 ℃...

Embodiment 2

[0091] A kind of raising method of large-scale cultivation tea inchworm, its step is:

[0092] A, the collected ovum is put into the biochemical incubator after being sterilized by formaldehyde;

[0093] B. The hatched tea geometrid larvae are inserted into the prepared feed for feeding, the temperature is controlled at 25-28°C, and the time is controlled at 48h;

[0094] C. When the larvae grow to the sixth instar, they are transferred to a single insect culture tray and prepared to pupate. The temperature is controlled at 25-28°C and the time is controlled within one week.

[0095] D. Collect tea inchworm pupae and put them in the spawning box to lay eggs, then repeat the steps A-D to carry out circular feeding. After the eggs are sterilized, put them in the incubator for 48 hours → insert the feed for a week → divide into plates, pupate → emerge, and lay eggs. A cycle, a cycle of generations, breaks the dormant period of the tea geometrid.

Abstract

The invention discloses a feed for breeding ectropis obliqua, a preparation method of the feed, and a breeding method of the ectropis obliqua. The feed is prepared from agar, potassium sorbate, butylparaben, casein, vitamin C, complex vitamins, defatted bean powder, sambucus chinensis powder, malt flour and water according to a ratio. The preparation method comprises the steps: proportionally weighing the raw materials; B, heating and dissolving the agar with the purified water, cooling, adding the potassium sorbate and the nipagin, and stirring evenly to obtain a mixture A; C, pouring the casein, the vitamin C, the complex vitamins, the defatted bean powder, the sambucus chinensis powder and the malt flour into a stirrer, adding the water and stirring evenly to obtain a mixture B; D, pouring the mixture A obtained in the step (B) and the mixture B obtained in the step (C) into the stirrer and stirring evenly to obtain a mixture C, and then pouring the mixture C in a sterilized container, and cooling to solidification to obtain the feed. The feed is reasonable in formula and convenient to use; the preparation method is easy to implement and simple and convenient to operate; the cost is reduced; as the sambucus chinensis is cultivated all through the year and easy to survive, the sambucus chinensis is suitable for large-scale breeding of the ectropis obliqua.

Description

technical field [0001] The invention belongs to the technical field of healthy breeding of tea geometrid larvae, production of tea geometrid nuclear polyhedrosis virus and all the technical fields of using tea geometrid as a test insect to detect biological efficacy, and more specifically relates to a feed for large-scale cultivation of tea geometrid. It also relates to a method for preparing feed for large-scale cultivation of tea inchworms, and also relates to a method for raising large-scale cultivation of tea inchworms. Background technique [0002] tea inchworm Ectropis oblique Warren is one of the main pests of tea trees in my country. It mainly feeds on the young leaves of tea trees. The insect is mainly distributed in provinces such as Zhejiang, Anhui, Jiangsu, Hunan, Hubei, Jiangxi and Fujian, especially in tea areas such as Zhejiang, Jiangsu and Anhui. In order to control its harm, people often use chemical pesticides for prevention and control, resulting in sig...
