Artificial feeding and generation method of Ectropis oblique hypulin W. and artificial feed for its larva

Abstract

The present invention discloses an artificial culture and sub culture method for the Ectropis oblique hypulin Wehrli, including the following steps: (1) burying the larvas in sandy soil after the pupas of Ectropis oblique hypulin Wehrlis become larvae for 2 days, thus becoming adult through eclosion at room temperature; (2) pairing male adult with female adult, and putting them in a culture container containing nutritive liquid for mating and spawning; (3) carrying out conventional disinfection of ova; (4) inoculating the larvae into a feeding container having feed for culturing the larvae of the Ectropis oblique hypulin Wehrli and culturing the larvae in a healthy insectary, wherein the feed for culturing the larvae of the Ectropis oblique hypulin Wehrli is proportionally prepared from 10.5 to 12.2 parts of wheat's germinal bud, 2 to 4 parts of casein, 0.3 to 1.5 parts of Wei's salt, 0.2 to 0.4 parts of sorbic acid, 0.1 to 0.36 parts of nipagin, 0.48 to 0.88 parts of VC, 0.17 to 0.78 parts of VB, 1.2 to 1.8 parts of agar, 0.05 to 0.08 parts of inositol and 78 to 85 parts of water; and (5) regulating feed 1-5 times and culturing until the larvae be pupated.

Description

technical field [0001] The invention relates to a method for artificially raising and inheriting tea geometrids. 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 mild medicine and healthy drink ne...

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
