Embodiment 2

[0077] Embodiment two: comparative test

[0078] Comparative experiment 1: Screening of host plants

[0079] 1. Materials and methods

[0080] 1) Insects to be tested

[0081] Plutella xylostella, which was used for multi-generation experiments in this laboratory.

[0082] Plutella xylostella was collected from the cabbage field in the late growth stage of our hospital.

[0083] 2) Host plant

[0084] Cabbage, cauliflower, Chinese cabbage, and rapeseed were used as test hosts.

[0085] Seeds of cabbage, cauliflower, Chinese cabbage, and rapeseed were purchased from the Special Vegetable Center of Vegetable Institute, Beijing Academy of Agriculture and Forestry Sciences.

[0086] 3) Test conditions and equipment

[0087] The test is carried out indoors, the temperature is controlled at 25-27°C, and the relative humidity is 55-75%. Cover with 120-mesh nylon wire mesh; host plants are planted in plastic seedling pots, and the cultivation substrate is plow layer soil / peat s...

Abstract

The invention discloses a plutella xylostella cotesia rubecula artificial propagation production method which comprises the following steps: collecting and propagating plutella xylostella cotesia rubecula species, producing hosts, conducting inoculation, propagation, development and feeding on plutella xylostella, conducting inoculation and cultivation on plutella xylostella cotesia rubecula, separating the plutella xylostella cotesia rubecula from the plutella xylostella, and conducting collecting, reserving and seed stock on plutella xylostella cotesia rubecula pupae. By means of the scheme of the plutella xylostella cotesia rubecula artificial propagation production method, advantaged plutella xylostella cotesia rubecula specie selection, propagation and pasturing technology is completed, high-quality, efficient and mass plutella xylostella cotesia rubecula propagation is achieved, mass production can be carried out, the plutella xylostella cotesia rubecula artificial propagation production method is applied to the technical field of biological control over agricultural pests, the plutella xylostella cotesia rubecula artificial propagation production method is used for preventing and treating primary pests such as the plutella xylostella on brassicaceous vegetables and meets production requirements of organic vegetables and green vegetables.

Description

technical field [0001] The invention relates to a breeding and production process of bees, in particular to a production method for artificial breeding of Braconis xylostella xylostella, belonging to the technical field of biological control of agricultural pests. Background technique [0002] Diamondback moth Plutella xylostella (Linnaeus) is an important pest on cruciferous vegetables. Diamondback moth causes great economic losses every year around the world. The annual loss and control costs of diamondback moth in the world exceed 4 billion US dollars; In recent years, the occurrence of diamondback moth has increased year by year, and the resistance to pesticides has become stronger and stronger, rampantly endangering the production of cruciferous vegetables in my country; because diamondback moth spends most of its time on the back of plant leaves, it is difficult to control, resulting in many As a result, the pesticide residues in the produced vegetables seriously exceede...
