Problems solved by technology

[0003] In recent years, many entomologists have been exploring the indoor breeding methods of tea inchworms, among which artificial feed formula and hydroponics are more representative; in 2005, the Institute of Forest Protection of the Chinese Academy of Forestry Sciences, and in 2007, Zhejiang Academy of Agricultural Sciences respectively disclosed Patent for the preparation and feeding method of tea geometrid artificial feed, but the cost of artificial feed is high, the larval survival rate is only about 7

Embodiment Construction

[0026] The technical solutions of the present invention will be described in further detail below through specific implementation methods.

[0027] A kind of tea geometrid indoor fresh leaf subculture breeding method, this method comprises the following steps:

[0028] Step 1. Indoor sand cultivation of branches: put the sterilized sand into the raising container, inject water into the raising container, keep the sand reaching the saturated water level and the surface layer of the sand has no clear water, and then insert the newly collected tea tree branches into the In the sand; wherein, the sterilized sand refers to soaking the sand in lime water for 3-5 hours and washing it clean; the sand is selected from medium sand with a particle size of 0.3--0.5 mm, and the height of the sand is the height of the breeding container. 1 / 2--2 / 3; Rearing container can adopt plastic bucket, plastic basin, fresh-keeping box etc., as long as it is the container of watertight all can use; What...

Abstract

The invention provides a method for subculturing Ectropis oblique hypulina Wehrli indoor with fresh leaves. The method comprises the following steps of: putting disinfected sand into a raising container, and injecting water; keeping the reasonable water quantity of the sand; inserting a tea tree branch into the sand; placing an Ectropis oblique hypulina Wehrli larva collected in the field onto the tea tree branch; covering the raising container with a silk curtain of 180-200 meshes; enabling the Ectropis oblique hypulina Wehrli larva to arbitrarily take food, and adding or replacing the tea tree branch according to the consumption situation of the tea leaves; in the old and mature larva pupating process, reducing water content of the sand; in the process of feathering the pupa into an adult, adding or replacing the tea tree branch; after an egg is hatched, adding a tender tea tree branch; and repeating the abovementioned steps, and successively circulating to achieve the purpose of subculturing the Ectropis oblique hypulina Wehrli indoor with the fresh leaves. The method has the advantages of low cost, easily obtainable materials, high larva survival rate and good larva growth anddevelopment condition.

Description

technical field [0001] The invention relates to a method for raising tea geometrids, in particular to a method for raising fresh leaves of tea geometrids indoors. Background technique [0002] Tea looper (Ectropis obliqua hypulina Wehrli) belongs to the Lepidoptera looper moth family insects, commonly known as arch worms, arch back worms, hanging silk worms, bridge builders and so on. As long as there are areas where tea trees are distributed, there will be tea geometrids, which occur in Zhejiang, Jiangsu, Anhui, Jiangxi, Hubei, Hunan, Sichuan, Guangdong, Henan and other provinces. It is the most serious pest on tea trees. When a large outbreak occurs, the entire tea garden is often eaten up, and it looks like a fire, which has a great impact on tea production. Due to the large number of generations of this insect, heavy overlapping of generations, fast reproduction speed and strong diffusion ability, it is easy to break out into disasters. It is particularly noteworthy th...
