Embodiment 1

[0019] Embodiment one: reduce nuclear polyhedrosis virus infection

[0020] (1) Dissolve 10 g of ribavirin, terbinafine hydrochloride and ammonium chloride mixture in 200 ml of water, spray 2.5 kg of mulberry leaves, and spray mulberry leaves with drug-free water at the same time, and feed them to 5th instar silkworms after drying (variety: Jingsong ╳ Haoyue) for 8 hours, the former is the treatment group and the latter is the control group;

[0021] (2) Mulberry leaves were impregnated with 10 per ml 8 and 10 7 The silkworm karyopolyhedron suspension, after drying slightly, fed the treatment group and control group silkworms of step (1) respectively for 8 hours, and then reared with common mulberry leaves;

[0022] (3) On the 3rd day of the 5th instar, the silkworms in the treatment group of step (2) and the control group were fed with the drug-sprayed mulberry leaves and water-sprayed mulberry leaves in step (1) for 8 hours, and then fed with common mulberry leaves;

Embodiment 2

[0029] Embodiment two: reduce plasmotype polyhedrosis virus infection

[0030] (1) Dissolve 7.5 g of ribavirin, terbinafine hydrochloride and ammonium chloride mixture in 250 ml of water, spray 2 kg of mulberry leaves, and spray mulberry leaves with drug-free water at the same time, and feed them to 4th instar silkworms after drying (species: Jingsong ╳ Haoyue) for 8 hours, the former is the treatment group and the latter is the control group;

[0031] (2) Mulberry leaves were impregnated with 10 per ml 7 and 10 6 The silkworm cytoplasmic polyhedron suspension, after drying slightly, fed the treatment group and control group silkworms of step (1) respectively for 8 hours, and then reared with common mulberry leaves;

[0032] (3) On the 3rd day of the 4th instar, the silkworms in the treatment group of step (2) and the control group were fed with the drug-sprayed mulberry leaves of step (1) and the water-sprayed mulberry leaves for 8 hours, and then fed with common mulberry l...

Embodiment 3

[0039] Embodiment three: reduce Beauveria bassiana infection

[0040] (1) 5th instar silkworm (species: Jingsong ╳ Haoyue) body spray contains 10 per ml 10 Suspension of conidia of Beauveria bassiana;

[0041] (2) Divide the silkworms in step (1) into a treatment group and a control group;

[0042] (3) Treatment group silkworm: 10 g of ribavirin, terbinafine hydrochloride and ammonium chloride mixture was dissolved in 250 ml of water, sprayed with 2 kg of mulberry leaves, dried and fed for 12 hours;

[0043] Control group silkworm: Spray 2kg mulberry leaves with 250ml of clear water, dry and feed for 12 hours; then feed with ordinary mulberry leaves;

[0044] (4) On the 3rd and 5th day of the 5th instar, the silkworms in the treatment group and the control group in step (3) were fed with medicine sprayed mulberry leaves and clear water sprayed with mulberry leaves for 8 hours, and at other times were fed with ordinary mulberry leaves until clustering, The incidence of Beauv...

Abstract

The invention discloses a method for improving silkworm cocoon yield stability, which comprises the following steps: (1), a mixture composed of virazole, terbinafine hydrochloride and ammonium chloride is used to prepare an aqueous solution according to the mass fraction of 10-15 to 3-7 to 75-85; (2), after the prepared aqueous solution is sprayed to mulberry leaves, mulberry leaves are dried in the air; (3), the mulberry leaves obtained in the step (2) are used for feeding silkworms. According to the invention, by adding the aqueous solution of the mixture composed of virazole, terbinafine hydrochloride and ammonium chloride, prevention and treatment for diseases of the silkworms, such as nuclear polyhedrosis virus, cytoplasmic polyhedrosis and white muscardine, can be achieved, the problem of silkworm cocoon yield reduction caused by the diseases can be solved, and the silkworm cocoon yield stability is ensured.

Description

technical field [0001] The invention relates to a method for improving the stability of silkworm cocoon output, in particular to a method for reducing the occurrence of viral diseases and fungal diseases in silkworm rearing production and improving the stability of silkworm cocoon output. Background technique [0002] In sericulture production, cocoon yield failure is often caused by the occurrence of infectious silkworm diseases in 4th and 5th instar silkworms. The infectious silkworm diseases that affect the stability of silkworm cocoon yield mainly include silkworm karyotype polyhedrosis, cytoplasmic polyhedrosis, and beauveria. At present, the prevention and control of the above-mentioned infectious silkworm diseases in sericulture production mainly adopts comprehensive prevention and control measures. The main measures are: (1) Breeding disease-resistant varieties; (2) Thoroughly disinfecting silkworm rooms and silkworm tools before raising silkworms; (3) Satisfy good m...
