Embodiment 1

[0027] A method for artificial conservation and breeding of tobacco mealworm, comprising the following steps:

[0028] (1) Equipment preparation: Prepare several plastic boxes with covers, the length*width*height specifications are 20*10*8cm, arrange 6 small holes evenly on the lid of each plastic box, and the hole diameter is 0.08cm ;

[0029] (2) laying the tobacco leaf layer: prepare the cured tobacco leaves with a moisture content of 13%, the tobacco leaves are tobacco leaves of grades above C3F, cut the tobacco leaves with scissors, cut the tobacco leaves into smaller shapes, and lay a layer of cut tobacco leaves on the In the plastic box prepared in step (1);

[0030] (3) Select robust host larvae: in the 5th instar larvae from the tobacco mealworm in Enshi, Hubei, use a writing brush to dip the relatively large larvae individuals into the tobacco leaves laid in step (2) one by one;

[0031] (4) Placement in layers: evenly place tobacco powder borer larvae on the tobac...

Abstract

The present invention relates to the technical field of biological control of agricultural pests, in particular to a method for artificial seed conservation and breeding of tobacco powder borer, which can provide insect sources in time, and then provide a large number of hosts for the breeding of natural enemy insects, which is helpful for exploring the adaptation of insects to the environment Mechanism; including the following steps: (1) equipment preparation; (2) laying the tobacco leaf layer; (3) selecting robust host larvae; (4) laying in layers: place the tobacco powder borer larvae evenly on the tobacco leaves in the plastic box, and place the density About 0.5 strips / cm 2 , Repeat steps (2) and (3) after each layer is full, until it is 1cm away from the box opening, spread tobacco leaves on the top layer, and close the box cover; (5) Store in the refrigerator; (6) Restore vitality; (7) Pupation: put the surviving larvae of Tobacillus moth into larvae cages and feed them until the larvae of Tobacillus melanogaster pupate normally to obtain pupae of Tobacillus moth; (8) Eclosion; (9) Egg mass collection and hatching; (10) Larval feeding.

Description

technical field [0001] The invention relates to the technical field of biological control of agricultural pests, in particular to an artificial breeding method for tobacco mealworms. Background technique [0002] The wasp is an omnivorous and gregarious ectoparasitic wasp that parasitizes the larvae of Lepidoptera pests and is widely distributed all over the world. It is an important parasitic natural enemy of Lepidoptera pests in fields and warehouses. Its parasitic ability Strong, rapid reproduction, and has good application prospects in the field of biological control. [0003] In the process of breeding and cultivating Braconidia spp., the tobacco mealworm is used as the host of the mealybug, which can rapidly reproduce a large number of Braconis spp. Large-scale production and application are of great significance. [0004] However, there is no complete technical report on the conservation and breeding of the tobacco mealworm. Contents of the invention [0005] In ...
