Orius sauteri egg preservation method suitable for large-scale breeding

Abstract

The invention belongs to the technical field of insect pest prevention and treatment, and particularly relates to an Orius sauteri egg preservation method suitable for large-scale breeding. The Orius sauteri egg preservation method suitable for the large-scale breeding comprises research of egg-laying substrate selection and research of a low-temperature preservation method, wherein the research of the low-temperature preservation method comprises research of constant-temperature condition preservation and research of varied-temperature condition preservation. By use of the Orius sauteri egg preservation method suitable for the large-scale breeding, kidney beans with a high hatching rate, good preservation performance, rot resistance and cold storage resistance are selected to serve as an egg-laying substrate, the hatching rate of the Orius sauteri is improved through the varied-temperature preservation way, the commercialization, popularization and application process of the Orius sauteri is quickened, the invention is favorable for preventing and treating pests in China and is an egg laying substrate which can be easily obtained, has a low cost, can supplement water, has good preservation performance, resists cold storage, has more implanted eggs, has the high hatching rate and can be preserved for a long time, and the low-temperature preservation method, and the Orius sauteri egg preservation method suitable for the large-scale breeding more favorably provides technical support for the large-scale breeding of the Orius sauteri.

Description

technical field [0001] The invention belongs to the technical field of pest control, and in particular relates to a method for preserving eggs of stink bugs suitable for large-scale breeding. Background technique [0002] The East Asian flower bug belongs to the family Hemiptera, and it is the dominant natural enemy of small agricultural and forest pests. Its adults and nymphs can prey on small arthropods such as thrips, aphids, spider mites, whiteflies, and various scales. Insect eggs and newly hatched larvae. The insect has the advantages of strong adaptability to the environment, wide distribution range, large number of occurrences, and miscellaneous feeding habits. It is generally considered to be a predatory natural enemy insect with high utilization value and biocontrol potential. At present, the East Asian flower bug has been widely used in farmland and greenhouse ecosystems such as vegetables, fruit trees, and flowers, and has played a good role in controlling pests...

AI Technical Summary

Problems solved by technology

[0006] However, the Swallow palm leaves, soybean sprouts, and Shouxing flower tender stems reported above as oviposition substrates have certain limitations in the actual large-scale production of the East Asian stinkbug. During the process of egg laying and egg hatching, use absorbent cotton to replenish water, otherwise it will easily dry out, affect the amount of eggs laid and hatching rate, and at the same time increase the number of operations, increase the cost, and greatly reduce the efficiency

Second, in the process of egg cryopreservation, moisturizing is also required to maintain the freshness of the egg-laying matrix, which has poor stability and complicated procedures

The third is that the storage time for East Asian small flower stinkbug eggs is relatively short, and the hatching rate is not ideal after the preservation of swallow palm leaves and Shouxing flower tender stems for more than 15 days

Although the leaves of soybean sprouts and the tender stems of Shouxing flower have been preserved for a long time, the egg production of soybean sprouts as an oviposition substrate is low. At the same time, the experimental data are mainly at the research level, and the operability in actual production is not strong.
