Example Embodiment

[0016] Example 1

[0017] Take the example of using water spinach to propagate the Aphid spp. in a tobacco seedling shed with a length of 20 meters and a width of 6 meters:

[0018] Step 1: Set up two nutrient pools with a length of 19m and a width of 2m in the flue-cured tobacco seedling shed, and divide them into 12 nursery areas with a length of 3m and a width of 2m. Each nursery area builds a square frame with a height of 1.6 meters. A 60-mu insect-proof net was used to seal an independent propagation room, and an ammonium sulfate fertilizer solution with a nitrogen concentration of 150 ppm was added to the nutrient pool in each seedling area as a base fertilizer, and the solution depth was 1.5 cm.

[0019] The second step: sow the water spinach seeds in a 50-hole moist seedling tray equipped with a tobacco seedling substrate. The length of the seedling tray is 54cm, the width is 28cm, the upper diameter of the hole is 5.0cm, the lower diameter is 2.5cm, and the depth is 5...

Abstract

The invention discloses a method for expanding propagation of aphidius gifuensis mummified aphids by utilizing water spinach. The method is characterized in that a tobacco moistening and seedling culture manner is adopted for planting the water spinach as a host plant, aphid inoculation and bee inoculation are respectively carried out in different growth periods of the water spinach for expanding propagation of the aphidius gifuensis mummified aphids, and multi-batch propagation expanding can be carried out during one sowing and planting. The method disclosed by the invention comprises the following concrete steps: a, preparing a propagation expanding chamber; b, sowing the water spinach and managing; c, inoculating aphids and breeding; d, inoculating the aphidius gifuensis, and breeding mummified aphids; e, collecting the aphidius gifuensis mummified aphids; and f, carrying out propagation expanding again. The method disclosed by the invention has the advantages that a flue-cured tobacco moistening and seedling culture manner is used for replacing tobacco as the host plant for breeding the aphidius gifuensis mummified aphids, the characteristics of the water spinach that the water spinach can be easily infected with aphids, a seedling formation period is short and the water spinach can be harvested for multiple times are utilized, short-period multi-batch propagation expanding of the aphidius gifuensis mummified aphids during one planting can be realized, propagation expanding amount is sufficient, propagation cost is low, and an existing tobacco seedling raising facility can be fully utilized, so that rational utilization of resource is realized.

Description

technical field [0001] The invention discloses a method for multiplying the aphid aphid by using water spinach, and belongs to the technical field of insect feeding and pest biological control. Background technique [0002] Aphids aphids prevention and control is a biological control technology that utilizes natural enemy insects Aphids aphids to parasitize aphids. It can reduce the use of chemical pesticides in the production process of tobacco leaves and improve the safety of raw materials of tobacco leaves. It has been widely promoted and applied in tobacco areas across the country. In the tobacco planting season, it is generally necessary to release bees at least twice to achieve the effect of aphid control. At present, most of the bee release methods are to scatter the tobacco seedlings with Aphids aphids in the field, and multiple releases need to be done at different times. Tobacco seedlings are raised in batches and Aphids persicae are propagated separately. This met...
