Problems solved by technology

[0003] However, the traditional breeding of aphids is a highly technical job with high requirements on the quality of management personnel, nutrient supply level, environmental temperature and humidity, etc.
This method usually needs to choose the right time, and through multiple inoculations and even inoculations, the aphids can be rep

Example Embodiment

[0056] Example 1

[0057] A field rapid propagation method of Myzus persicae, including the following steps:

[0058] 1) Location selection: choose an area where the terrain is higher, the terrain is at the "upwind" position of the main wind direction of the control season, and the soil fertility is above medium, so as to facilitate the migration of Myzus persicae or expand the migration range;

[0059] 2) Selection of host crops for receiving aphid: select tobacco as the host crop for receiving aphid;

[0060] 3) Spatial layout: 1 breeding point is set up for every 30 acres of prevention and control area, and each breeding point cultivates 30m of host crops 2 Carry out spatial layout;

[0061] 4) Time selection: 15 days before transplanting or sowing the spring crops to be cultivated in the prevention and control area, start to cultivate aphid host crops;

[0062] 5) Cultivation measures:

[0063] A. Plant row spacing: The planting row spacing is 0.8m, and 3 rows are opened. The plant sp...

Abstract

The invention discloses a rapid field breeding method of aphidius gifuensis. The breeding method comprises the following steps of place selection, aphid inoculation host crop selection, space layout, time selection, cultivation measures, aphid breed inoculation, bee breed inoculation and post-processing. The problem that technical requirements of traditional aphidius gifuensis breeding are high is effectively solved, a good parasitism place is provided for aphidius gifuensis breeding, the middle links of inoculation are greatly simplified, the uniformity requirements of inoculation are reduced, the aphidius gifuensis breeding speed can be also multiplied, individual development is good, accordingly the artificial aphidius gifuensis breeding efficiency is greatly improved, and the labor and material costs are reduced.

Description

technical field [0001] The invention belongs to the technical field of tobacco pest prevention and control, and in particular relates to a field rapid propagation method of Aphids persicae. Background technique [0002] Myzus persicae (Sulzer), also known as Myzus persicae (Sulzer), is a common pest that harms Solanaceae (such as tobacco, eggplant) and Rosaceae (such as peach trees). At present, the best way to prevent and control aphids is to artificially reproduce a large number of healthy aphids, and then let a small amount of Aphids aphids parasitize on these aphids, and these parasitized aphids become inactive The dead aphid, that is, the "semi-finished product" of the Aphidia persicae, is released in batches into the tobacco field and the large agricultural environment, and soon hatches into the A. purpose of pests. [0003] However, the traditional breeding of aphids is a highly technical job that requires high quality of management personnel, nutrient supply level,...
