[0003] However, after 3 years of practical promotion and application, the applicant found that: in the original patent application, the tobacco seedlings with 3 to 4 leaves and 1 core were used to connect aphids and propagate aphids. Poor growth of seedlings causes a large number of parasitic aphids to escape or die, and the amount of stiff aphids formed is relatively sm...

Embodiment 1
[0034] Example 1 (Comparison of bee breeding effects between two tobacco seedling treatment methods)
[0035] (1) Cultivate tobacco seedlings
[0036] In the same bee breeding shed, use length * width * height to be 66.5cm * 34cm * 5.5cm, 162 hole specifications floating plate, sow seedlings according to the requirements of floating seedlings.
[0037] (2) Picking up aphids and multiplying aphids
[0038] Treatment Ⅰ (original method): When the tobacco seedlings have 3 to 4 true leaves, spread the aphid leaves on the tobacco seedlings with the back of the leaves facing down, and let the aphids spread by themselves. When there are about 10 aphids on the tobacco seedlings on average, When the head / plant is planted, replace the aphid leaf with a new tobacco seedling, and cover it with a 60-mesh insect-proof net in time after the aphid is picked up.
[0039] Treatment II (the method of the present invention): when the tobacco seedlings have 5 true leaves, cut the leaves on...

[0048] (1) Cultivate tobacco seedlings
[0049] In the same bee breeding shed, use length * width * height to be 66.5cm * 34cm * 5.5cm, 162 hole specifications floating plate, sow seedlings according to the requirements of floating seedlings.
[0050] (2) Aphids and bees
[0051] Treatment Ⅰ (original method): When the tobacco seedlings have 3 to 4 true leaves, spread the aphid leaves on the tobacco seedlings with the back of the leaves facing down, and let the aphids spread by themselves. When there are about 10 aphids on the tobacco seedlings on average, When the head / plant is planted, replace the aphid leaf with a new tobacco seedling, and cover it with a 60-mesh insect-proof net in time after the aphid is picked up. When the average number of aphids is about 260 heads / plant within 15 days after receiving aphids, the adult bees or dead aphid seedlings are respectiv...

Abstract
The invention discloses a method for breeding aphidius gifuensis ashmead through floating tobacco seedlings, particularly relates to a method for breeding aphidius gifuensis ashmead through floating tobacco seedlings, which is realized through breeding aphids by cultivating uniform, robust tobacco seedling with proper density and inoculating mummified aphids under net covering condition, and belongs to the technical field of insect breeding and biological control of injurious insects. According to the technical system for breeding aphidius gifuensis ashmead efficiently through floating tobacco seedlings, innovation is achieved in the three aphidius gifuensis ashmead breeding steps including host plant cultivation, host myzus persicae breeding and aphidius gifuensis ashmead breeding, the aphidius gifuensis ashmead breeding cycle is shortened to be two months, and the number of mummified aphids and parasitic aphids existing in each square meter can reach over one hundred and twenty thousand; the steps such as tobacco plant transplantation and cultivation are omitted, management is easy and convenient, and a small number of manpower and material resources are needed. By the adoption of the method for breeding aphidius gifuensis ashmead through floating tobacco seedlings, the aphidius gifuensis ashmead can be bred by fully utilizing existing breeding facilities, aphidius gifuensis ashmead breeding facility investment is reduced, and aphidius gifuensis ashmead breeding cost is reduced. The method is tested in large-scale aphidius gifuensis ashmead breeding work, the time efficiency, the unit-area efficiency, the management efficiency, the aphidius gifuensis ashmead breeding facility utilization rate and other aspects of large-scale aphidius gifuensis ashmead breeding are improved comprehensively, the aphidius gifuensis ashmead breeding cost is reduced greatly, and the method for breeding aphidius gifuensis ashmead is adopted by most tobacco enterprises in China.
Description
technical field [0001] The present invention relates to a method for propagating aphids from floating tobacco seedlings, in particular to cultivating tidy and robust tobacco seedlings with suitable density for propagating aphids, picking up stiff aphid seedlings in a timely manner, and breeding bees from floating tobacco seedlings under the condition of covering nets, which belongs to insect breeding and the technical field of pest biological control. Background technique [0002] The Chinese patent (application number or patent number: 201110209370.2) of the invention title "Method for Propagating Aphids persicae with Floating Seedlings Efficiently Propagated by Floating Seedlings" that the applicant has declared discloses the use of seedling-growing sheds, field seedling-growing sheds and In the nursery pool, 162-hole or 200-hole floating trays are used for interlaced sowing and floating seedling raising; when the tobacco seedlings have 3 to 4 true leaves, aphids are picke...
