Embodiment 1

[0020] Take a 500mL wide-mouth glass jar, and put 200-300 eggs in each bottle (you can pick it up with a small brush). After the larvae hatch, they are thrown into the young shoots of the tea tree and sealed with white paper and rubber bands. On the 1st day, the paper and the mouth of the bottle must be tightly combined to prevent the newly hatched larvae from crawling and escaping. After most of the feed is eaten, new feed needs to be added in time. After 2-3 days of feeding, the cuttings are used for feeding. Cut the tea branches with tender shoots from the field, and insert them in bundles into a 500mL wide-mouth bottle filled with water. Put 3-4 bottles of tea branches close together in a plastic pot with a diameter of 60 cm to form a small tea canopy. The larvae (6 bottles) in the worm bottle are moved to the tea canopy, and allowed to spread and get food on the tea canopy. After the 4th age, add or replace tea sticks in a timely manner according to the feeding situat...

Abstract

The invention relates to a method for collecting and storing eggs in the mass rearing process of tea geometrid and belongs to the technical field of insect rearing. The method comprises the following steps: 1, carrying out mass rearing of larvae of tea geometrid; 2, collecting pupae of tea geometrid; 3, enabling adults of tea geometrid to lay eggs and collecting the eggs; 4, carrying out cold storage of the eggs of tea geometrid. The method has the following benefits that 1, the method is rapid, simple and convenient to take the eggs, has high efficiency, is particularly suitable for the mass rearing of tea geometrid and omits the steps of adult pairing, making of egg laying strips and the like in an existing method, the adults are reared in a centralized manner, the adults directly lay the eggs on white paper, the method is very convenient to carry out egg taking operation and is time-saving and labor-saving, meanwhile, a small number of appliances are used and the rearing space is saved; 2, the egg cold storage time is prolonged by adopting a method of moisturizing in a refrigerating bottle, the egg retention period of the method is prolonged to 20 days from 15 days before and is prolonged by 5 days relative to that of a conventional cold storage method, rearing batches in the mass rearing process of tea geometrid can be increased, and the total rearing number is increased.

Description

technical field [0001] The invention belongs to the technical field of insect rearing, and in particular relates to a method for collecting and preserving eggs in large-scale feeding of tea geometrids. Background technique [0002] Tea geometrid is the main pest all over the tea-producing provinces in my country. Large-scale breeding of tea geometrid is the basis for the propagation of tea geometrid virus and various experimental studies. Egg collection and storage influence the size and duration of mass rearing. At present, the method of collecting eggs in large-scale breeding of tea geometrids is the ovipositing strip method, that is, after the adults emerge, 1-2 pairs of male and female adults are placed in a 500mL wide-mouth glass jar, and 1-3 eggs are placed in the bottle at the same time. Spawning strips (length 10cm, width 2cm folded from three layers of paper, stapled together, with cracks). After the adult worms have laid eggs, take out the egg-laying strips and ...
