Embodiment 1

[0025] Experiment site: Kunming Xundian Tobacco Technology Extension Station

[0026] experimental method:

[0027] 1. Collect 2.5g (5082 aphids) of zombified aphids for 2-3 days;

[0028] 2. Mix 10g of buckwheat husks with 2g of water evenly, then add 2.5g of aphids, mix evenly, and then put them into a round plastic bottle with a diameter of 8.5cm for airtight storage;

[0029] 3. Put the above-mentioned round plastic bottle into the cold storage, keep it dark, the temperature in the cold storage rises from 2°C to 4°C, then drops from 4°C to 2°C, and so on; from 2°C to 4°C consumes 7-8 hours, it takes 7-8 hours to drop from 4°C to 2°C;

[0030] 4. Set 2 treatments: refrigerated for 25 days (treatment I) and 30 days (treatment II). After refrigerating, take out the round plastic bottle, open the plastic bottle cap, cover the opening of the plastic bottle with an 80-mesh insect-proof net, and then put the plastic bottle into the artificial climate box to allow the aphids to...

Abstract

The invention discloses a method for preserving aphidius gifuensis products. The method comprises the following steps of (1) collecting mummified aphids of aphidius gifuensis with a consistent developmental duration; (2) uniformly mixing matrix, the mummified aphids and water in proportion; (3) putting the mummified aphids which are evenly mixed with the matrix and the water in a cold storage forpreservation. The method achieves the long-term preservation of the aphidius gifuensis products, reduces the product loss caused by the preservation and reduces the product cost.

Description

technical field [0001] The invention relates to the technical field of biological control, in particular to a method for preserving products of Aphids aphids. Background technique [0002] The tobacco aphid (Myzus persicae) is a worldwide pest, and its feeding habits are mixed. In addition to tobacco, it also damages more than 170 other crops. Aphids tend to be tender, and most of them gather on the back of young leaves, sucking the juice, causing the leaves to shrink and deform, reducing the contents, and slowing down the growth of tobacco plants; the "honeydew" secreted by aphids often causes tobacco leaves to induce "soot". "Disease" makes the surface of the tobacco leaves black, and the leaves turn brown after baking. The indirect damage is the transmission of various viral diseases such as tobacco cucumber mosaic virus disease, and the winged aphid is the main medium of transmission. [0003] In the existing technologies, most of the aphids are killed by chemical pest...
