Problems solved by technology

However, in the existing breeding technology, there are still some problems in the selection of the species of Aphids persicae and the species of A. persicae, and the technical details of breeding bees, which will easily cause the efficiency and quality of breeding bees to be unstable, and affect the production of A. persicae. bee effect

Embodiment 1

[0036] The second generation of medium-speed bee breeding is adopted, and it is carried out 30 to 45 days before transplanting in a normal field. The details are as follows:

[0037] 1. The cultivation of host plant tobacco

[0038] Seedling raising: select K326 germination-coated species (Chinese invention ZL 0335483.1), adopt the floating seedling raising method (Chinese invention ZL 03108979.8), in a greenhouse or a greenhouse with an insect-proof net at 20°C to 25°C and a humidity of 60% to 70% ( As a seedling room) to grow seedlings until seedlings.

[0039] Transplanting: Transplant the bred tobacco into flower pots with a pot mouth diameter of 12-16 cm, a pot bottom diameter of 8 cm-10 cm, and a height of 15-20 cm. Cultivate for 12 days in a greenhouse or greenhouse (as a tobacco seedling cultivation room) with a net.

[0040] 2. Reproduction of aphids

[0041] The reproduction of aphids includes breeding of aphids, grafting of aphids, and propagation of aphids.

[...

Embodiment 2

[0052] The first generation of rapid multiplication of bees is adopted, as follows:

[0053] 1. For the cultivation of the host plant tobacco, K326 pregerminated coated species (Chinese invention ZL0335483.1) was selected, and sand seedling cultivation method (Chinese invention ZL 200510048691.3) was adopted, and cultivated for 15 days after transplanting. All the other are with embodiment 1.

[0054] 2. Reproduction of aphids

[0055] Breeding of aphids: Aphids are picked directly in the aphid breeding room.

[0056] Picking up aphids: Move the tobacco plants transplanted and cultivated for 15 days into pots at 20°C to 25°C, with a humidity of 50% to 60%, and a greenhouse or greenhouse with an insect-proof net (as a room for picking up aphids). Connect the tobacco aphids on each tobacco seedling in the way of head / plant. When picking aphids, pick IV-age nymphs and aphidless adults and evenly connect them to the middle and lower leaves of tobacco seedlings, and cultivate th...

Embodiment 3

[0064] Repeat Example 1, with the following differences: when the host plant tobacco seedlings are raised, the wet seedling raising method is used [Liu Tianyi, Huang Yilan, Lai Luxiang, etc. Research on moist seedling raising technology of flue-cured tobacco. China Tobacco Science. 2009, 29 (5): 22-26.] .

Abstract

The invention discloses a method for propagating sulzer braconid flies. The method comprises the following steps: firstly, culturing a host plant of tobaccos, then propagating sulzers and afterwards propagating the sulzer braconid flies by the sulzers. By propagating the flies in batches, the multi-generation repeated propagation of the sulzer braconid flies is avoided, the generation quantity ofthe hyperparasite flies of the sulzer braconid flies is reduced, and the survival capability of the sulzer braconid flies in the field is enhanced. The propagation time and quantity of the sulzer braconid flies can be flexibly regulated and controlled according to the actual condition of the field, and different requirements on the sulzer braconid flies under different situations are met. The emergence rate of the stiff aphids of the sulzer braconid flies propagated by the invention is more than 90%, the male-female ratio is 0.8-1.0:1, and the utilization rate of the stiff aphids or the adultflies is more than 80%.

Description

technical field [0001] The invention belongs to the technical field of biological control of diseases and insect pests, and relates to the utilization of natural enemy insects, in particular to a method for multiplying Aphids aphids. Background technique [0002] In recent years, the application of natural enemy insects has developed rapidly at home and abroad. The reproduction and release of Trichogramma and predatory mites have become a model for the use of natural enemy insects in my country. The use of natural enemy insects has developed into an important measure for crop pest control in modern agriculture. Apidius gifuensis Ashmead (Apidius gifuensis Ashmead) is an endoparasitic wasp specialized in parasitizing aphids and an important parasitic natural enemy of aphids. The natural parasitism rate of Aphidia persicae to A. persicae is usually between 20% and 60%, and can reach 89.16% at the highest [Zhao Wanyuan, Ding Chuiping. Research on the biology and application of ...
