Problems solved by technology

At present, the production of biopesticides mostly adopts the field inoculation method. The disadvantage is that there are many factors restricted by the external environment, such as: season, temperature, humidity, region, wind and rain, sand and dust, insect population density, tree height, terrain, etc., will affect the biological environment. The production of insecticides has brought adverse effects, resulting in extremely unstable production of bioinsecticides, and feeding larvae with natural feed also loses a lot of leaves, especially in general areas where mature larvae enter the soil and pupate one after another after October Overwintering, adults emerge and lay eggs in early and middle March of the following year, and the overwintering period lasts for 4-5 months. The interruption of insect sources makes relatively continuous large-scale production more difficult.
[0007] The existing artificial diets for tea geometrid larvae all contain a considerable amount of tea powder. Without this ingredient, tea geometrid larvae cannot complete the entire generation, and continuous feeding cannot be achieved.
Therefore, using this artificial feed will also lose a lot of tea

Embodiment 1

[0038] Initially select 8000 eggs of tea looper. Routinely disinfect all tea geometrid eggs (soak them in 10% formalin solution for 1 hour, then rinse them with clear water and dry them in the shade), hatch 6080 larvae at 25°C, and artificially feed the tea geometrid larvae Heat and mix according to formula 2 in Table 1, pack into tea geometrid larva rearing containers, insert newly hatched larvae (inject 30-50 newly hatched larvae in each container), and put them into a healthy insect breeding room to raise , depending on the feed situation, the feed was replaced at regular intervals, and 4356 pupae became pupae in 11 days. The pupae were put into moist sand (humidity should be able to form a group with hands and let go and basically disperse) for 8 days, and 3910 pupae emerged. Worm 1253, male worm 2657, every 1 pair of adults is put into 1 container, adds nutrition No. 5 liquid (put into a diameter in every container and be the aseptic cotton ball of 1.5cm, nutrition is add...

Embodiment 2

[0040]12,280 eggs of tea geometrid larvae, the feeding method and environmental conditions are the same as those in Example 1, 8596 larvae were hatched under the condition of 25°C, the artificial diet for tea geometrid larvae was heated and mixed according to formula 1, and packed into the breeding container of tea geometrid larvae. The newly hatched larvae were inserted and raised in a healthy insect breeding room. After 12 days, 6018 pupae became pupae. After 9 days, the pupae were placed in moist sand, and 5115 adults emerged, including 1790 females and 3325 males. Each pair Put the adults into a container, add No. 5 nutrition solution, the egg production is 152,150, the egg stage is 5 days, 111,069 larvae are hatched, and 10,000 larvae are left when they are raised to the 3rd instar, and the remaining 101,069 larvae replicate the virus to kill insects Agent, can be applied to 6700 acres.

Embodiment 3

[0042] Tea geometrid larvae 23140 grains, feeding method and environmental conditions are the same as in Example 1, under the condition of 25 ℃, 16429 larvae are hatched, and the artificial diet of tea geometrid larvae is heated and mixed according to formula 3, and then packed into the breeding container of tea geometrid larvae. The newly hatched larvae were inserted and raised in a healthy insect breeding room. After 11 days, 11,664 pupae became pupae. The pupae were placed in moist sand for 8 days, and 9,915 adults emerged, including 3,966 females and 5,949 males. Each pair Put the adults into a container, add No. 5 nutrition solution, the egg production is 341076, the egg stage is 5 days, 255807 larvae are hatched, and 10000 larvae are left when they are raised to the 3rd instar, and the remaining 245807 larvae replicate the virus to kill insects Agent, can be applied to 15000 acres.

Abstract

An artificial culture and passage method for the Ectropis oblique hypulin W. includes such steps as after the pupa of Ectropis oblique hypulin W. becomes larva for 2 days it is buried in sandy soil, eclosion to become adult, pairing male adult with female adult, putting them in a culture container containing nutritive liquid, mating, spawning, conventional disinfecting of ova, inoculating to obtain larvae, and artificial culturing while regulating feed 1-5 times. Said feed for culturing the larvae of tea looper is proportionally prepared from wheat's germinal bud, casein, Wei's salt, sorbic acid, nipagin, VC, VB, agar, inositol and water.

Description

technical field [0001] The invention relates to a method for artificial breeding and subculture of tea geometrids and artificial feed for larvae. Background technique [0002] Tea inchworm (Ectropis oblique Warren), distributed in Anhui, Jiangsu, Zhejiang, Jiangxi, Hubei, Hunan, Sichuan, Guangdong and Fujian provinces. It is one of the main pests of tea trees in my country. It harms both spring tea and summer and autumn tea. The annual damage period is as long as 7-8 months. In addition to harming tea trees, it also harms plants such as cherries, pomegranates, and maple poplars. [0003] Tea geometrids cause damage by biting the leaves with larvae, and bite the leaves into arc-shaped notches. When they are rampant, they often eat up all the leaves and leave only bare branches. disaster. Seriously affected the quality and output of tealeaves and tree vigor. [0004] Tea originated in my country and has a long history of more than 3,000 years. It has long been listed as a m...
