Novel method for breeding Clanis bilineata Walkers

Abstract

The invention discloses a novel method for breeding Clanis bilineata Walkers, comprising the following steps of: (1) selecting larvae; (2) preserving the larvae; (3) warming the larvae; (4) airing and catching one couple of moths; (5) mating and separating the moths; (6) visually inspecting oviposition and carrying out microscopic examination; (7) disinfecting and degumming ovum surfaces; (8) hatching and stocking. The method provided by the invention has the advantages that: 1, the indoor larvae-preserving mortality rate of the Clanis bilineata Walkers is low; 2, the larvae are warmed by raising a temperature through an artificial procedure, the pupation rate of the Clanis bilineata Walkers is high, the eclosion and mating rate is high, the ovum laying amount is great and the hatching rate is high; and 3, the larvae are warmed by batches and Clanis bilineata Walker products are put into the market by batches, so as to be good for the stability of a market price and ensure the income of raisers.

Description

technical field

[0001] The invention relates to the technical field of insect breeding, in particular to a method for doudan breeding. Background technique

[0002] The bean hawker (Clanis Bilineata Walker) is an insect belonging to the genus Lepidoptera, and is distributed in Hebei, Henan, Shandong, Anwei, Jiangsu, Hubei, Sichuan, Shaanxi and other provinces. The life cycle of the bean hawkmoth consists of four stages: egg, larva, pupa, and adult. Doudan is a common name for the larvae of the bean hawkmoth. There are five instars in the larval stage, and they overwinter in the form of mature larvae. Doudan is the main pest of soybean crops, and can also harm mung beans, cowpeas, etc. Doudan eats soybean leaves, which can eat the leaves into nicks. One bean dan can eat up 2 to 3 bean leaves.

[0003] Due to the rich nutrient content of doudan, many parts of our country have the habit of eating doudan. In particular, Guanyun County, Jiangsu Province, has a history of con...

Examples

Embodiment 1

[0033]Choose plump, robust, and no scars, as the doudan seeds. A breeding rack was set up in the seed preservation room, and the doudan seeds were spread thinly in a plastic turnover box, covered with 10 cm of sand, and then the plastic box was placed on the seed preservation rack, and the room temperature was 0°C and the humidity was 70%. In February, a batch of bean dan seeds was transferred to the warm seed room, and the temperature was gradually increased. The daily temperature increased by 1 °C, and after rising to 15 °C, the temperature was maintained to promote pupation and emergence. After the feathered bean hawkmoth spreads its wings, it is lured to fly onto the vertically hanging gauze with a black light. Checked every hour, the mated hawkmoths were gently caught in the mating basket and transferred to the mating chamber. Mating room temperature 15 ℃, ventilated, dark. The male and female moths were gently disassembled 8 hours after mating. After removing the pair...

Embodiment 2

[0035] Choose plump, robust, and no scars, as the doudan seeds. A breeding rack was built in the conservation room, and the doudan seeds were spread thinly on the conservation rack and covered with 10cm of sandy soil. Maintain room temperature at 5°C and humidity at 80%. In April, a batch of bean dan seeds was transferred to the warm seed room, and the temperature was gradually increased. The daily temperature increased by 2 °C, and after rising to 25 °C, the temperature was maintained at a flat temperature to promote its pupation and emergence. After the feathered bean hawkmoth spreads its wings, it is lured by a purple light to fly to a curtain made of vertically hanging straw. Checked every hour, the mated hawkmoths were gently caught in the mating basket and transferred to the mating chamber. Mating room temperature 25 ℃, ventilated, dark. The male and female moths were gently disassembled 10 hours after mating. The male moths were cooled at 10°C for protection and use...

Embodiment 3

[0037] Choose plump, robust, and no scars, as the doudan seeds. A breeding rack was set up in the seed preservation room, and the doudan seeds were spread thinly in a plastic turnover box, covered with 15cm of sand, and then the plastic box was placed on the seed preservation rack. Maintain a room temperature of 10°C and a humidity of 90%. In August, a batch of bean dan seeds was transferred to the warm seed room, and the temperature was gradually increased. The daily temperature increased by 2 °C, and after rising to 30 °C, the temperature was maintained to promote pupation and emergence. After the feathered bean hawkmoth spreads its wings, it is lured by black light or violet light to fly to the vertical hanging gauze or straw curtain. Checked every hour, the mated hawkmoths were gently caught in the mating basket and transferred to the mating chamber. The temperature of the mating room is 30℃, ventilated and dark. The male and female moths were gently disassembled 20 hou...
