Detailed Description
As shown in attached figures 1-5, the method for controlling the bad pupa disease of the Chouioia cunea Yang breeding of the white moth comprises the steps of putting a seed pupa 8 into a bee-warming bottle 1 made of a transparent plastic bottle, plugging a bottle stopper made of absorbent cotton into the bee-warming bottle, controlling the environmental temperature below 28 ℃, and waiting for the Chouioia cunea Yang 3 to emerge from the seed pupa;
when the Chouioia cunea Yang emerges from the pupae and breaks the shell for the next day or the third day, the temperature is controlled between 20 ℃ and 25 ℃, the bottle stopper is opened, the disinfectant is diluted, and then the Chouioia cunea Yang which has emerged in the Chouioia cunea Yang is quickly sprayed and disinfected by a sprayer 9 with better atomization at a distance of more than 1 meter from the Chouian Yang bee bottle; the bottle stopper is plugged back, and the bottle mouth is kept standing for 30 minutes;
manufacturing a net-covered type Chouioia cunea Yang breeding box 2, wherein the net-covered type Chouioia cunea Yang breeding box is similar to a traditional Chinese furniture 'holding box', and is divided into a box body 6 and a box cover 7, wherein the top surface of the box cover is a gauze 10, and four vertical surfaces of the box cover, 4 vertical surfaces of the box body and the bottom surface of the box body are all wood; uniformly placing the silkworm chrysalis 11 into a box body of a net-covered type Chouioia cunea Yang breeding box;
a tubular sterilizing lamp 5 is hung above an inoculation workbench 4 with the height of 1 m, and the distance between the sterilizing lamp tube and the floor is about 2 m. An operator wears an ultraviolet protective mask and linear gloves, wears long-sleeve work clothes and trousers without exposing skin, inoculates the Chouioia cunea Yang under a sterilizing lamp, beats a bee warming bottle and shakes a cotton wool plug to uniformly scatter the eclosion white moth Chouioia cunea Yang and the breeding pupae into the net-covered type Chouioia cunea Yang breeding box body 6, quickly covers a box cover 7 and seals gaps by using an adhesive tape;
placing the net-covered type Chouioia cunea Yang breeding box with the inoculated apis cerana on the floor or on an operation table, controlling the temperature to be between 20 and 23 ℃, and enabling the Chouioia cunea Yang to be laid on a gauze 10 of a box cover 7 due to phototaxis and the belly to be upward; the distance between the mesh-covered type Chouioia cunea Yang breeding box and the mesh-covered type Chouioia cunea Yang breeding box is about 1 m, an atomizer with good atomization is held to face a gauze 10 of the Chouioia cunea Yang breeding box 2, diluted disinfectant is used for fast spraying, and therefore the abdomen of the Chouioia cunea Yang and an ovipositor are sterilized and disinfected;
transferring the net-covered type Chouioia cunea Yang breeding box sterilized by the disinfectant to a bee breeding rack provided with a sterilizing lamp. When the sterilizing lamp is arranged above the bee breeding rack, the distance between the lamp tube and the mesh covering type hyphantria cunea breeding box gauze 10 is about 0.1 meter. When the sterilizing lamp is arranged on the rear wall, the distance between the lamp tube and the front edge of the top surface of the mesh-covered type Chouioia cunea Yang breeding box is less than 1 meter. Controlling the temperature at about 25 ℃, sterilizing for more than 15 minutes by irradiating a sterilizing lamp, turning off the sterilizing lamp, and keeping the dark light to ensure that the apis cerana smith are concentrated in the silkworm pupae to lay eggs. After that, the sterilizing lamp is turned on for 15 minutes every day, the adhesive tape is torn off after 1 to 2 days, the box cover 7 is taken down, and the breeding box 6 is kept open and is transferred to the temperature and humidity control culture stage.
The temperature of the culture stage can be adjusted between 10-28 deg.C according to the releasing time of bee, and the humidity can be controlled between 50-80%. The bee time can be calculated according to an effective temperature accumulating method provided by the technical regulation for artificial breeding and application of Chouioia cunea Yang to ensure that the bee time is matched with the pupation time of lepidopterous larvae such as fall webworms and the like; the actual release time is 3-5 days earlier than the bee-out time calculated by an effective temperature accumulating method, so that the phenomenon that the wasps are released before being released due to the fact that the wasps cannot be released in rainy days or the distribution and reception delay is caused is prevented. Certainly, if the conditions permit, when the Chouioia cunea Yang develops to the old larva stage, the parasitized tussah pupae can be transferred into a refrigerator or a refrigerating chamber at 0-3 ℃ for storage, and released at a proper time.
