Example Embodiment

[0021] Such as figure 1 As shown, the method for preparing the feed for Harmonia axyridis larvae provided by the embodiment of the present invention includes the following steps:

[0022] S101: Pass the pig liver powder through a double layer of 100 mesh gauze to remove larger particles to obtain extremely fine pig liver powder;

[0023] S102: Mix 15 parts of obtained pork liver powder with 1.5 parts of yeast powder evenly;

[0024] S103: Dissolve 3 parts of sucrose, 1.5 parts of honey and 0.02 parts to 0.03 parts of potassium sorbate in 15 parts of water;

[0025] S104: Dissolve 0.4 to 0.5 parts of β-carotene in 1 part of linseed oil + 1.5 parts of olive oil; the β-carotene is fully dissolved in linseed oil and olive oil by ultrasound, and the ultrasound time is 2 minutes;

[0026] S105: Mix the parts obtained in step S102, step S103, and step S104, and add 10 parts of water to fully stir to obtain a paste feed;

[0027] S106: Dispense the obtained artificial feed into 1.5ml centrifuge...

Example Embodiment

[0030] Example 1

[0031] (1) Preparation of pig liver powder: directly purchase pig liver powder (baby food supplement), pass the pig liver powder through a double-layer 100 mesh gauze to obtain extremely fine pig liver powder, and store it in a refrigerator at -20°C for later use.

[0032] (2) Preparation of β-carotene solution: add 0.45g β-carotene to a 10ml centrifuge tube containing 1g linseed oil + 1.5g olive oil, and place the centrifuge tube in an ultrasonic cleaner for 2 minutes to fully dissolve β-carotene. carotene.

[0033] (3) Add 3 g of sucrose, 1.5 g of honey and 0.02 g of potassium sorbate into a container containing 15 ml of sterile water, and stir to fully dissolve it.

[0034] (4) Mix 15 g of pig liver powder prepared in (1) with 1.5 g of yeast powder, 10 ml of sterile water and the solution obtained in (2) and (3).

[0035] (5) Dispense the Harmonia axyridis artificial feed obtained in (4) into 1.5 ml centrifuge tubes and store them in a refrigerator at -20°C.

Example Embodiment

[0037] Example 2

[0038] (1) Preparation of pork liver powder: Wash the impurities on the surface of fresh pork liver, dry it a bit, cut the liver into small pieces, place them in an iron pan covered with tin foil, and then transfer to a constant-temperature blast oven , Set the temperature to 65°C, take it out after 48 hours. Put the fully dried pork liver block in a pulverizer and pulverize it into powder. The obtained pig liver powder is passed through a double layer of 100 mesh gauze to obtain extremely fine pig liver powder, which is stored in a refrigerator at -20°C for later use.

[0039] (2) Preparation of β-carotene solution: add 0.45g β-carotene to a 10ml centrifuge tube containing 1g linseed oil + 1.5g olive oil, and place it in an ultrasonic cleaner for 2 minutes to fully dissolve β-carotene Vegetarian.

[0040] (3) Add 3 g of sucrose, 1.5 g of honey and 0.02 g of potassium sorbate into a container containing 15 ml of sterile water, and stir to fully dissolve it.

Abstract

The invention discloses harmonia axyridis larva raising feed and a preparation method thereof. The feed is prepared from, in parts by mass, 15 parts of pork liver powder, 1.5 parts of yeast powder, 3 parts of sucrose, 1.5 parts of honey, 1 part of linseed oil, 1.5 parts of olive oil, 0.4-0.5 parts of beta-carotene and 0.02-0.03 parts of potassium sorbate. The preparation method comprises steps as follows: the pork liver powder passes through a double-layer screen for removal of larger particles; 15 parts of the obtained pork liver powder are uniformly mixed with 1.5 parts of yeast powder; the sucrose, the honey and the potassium sorbate are fully dissolved in water; the beta-carotene is dissolved in the linseed oil and the olive oil; all components are mixed and fully stirred in water, and pasty feed is obtained; the obtained artificial feed is sub-packed in centrifugal tubes of 1.5 ml. Harmonia axyridis larvae like taking the feed, and the guarantee period of the feed is long; the obtained larvae have very high catching amount of green peach aphid pests, and obtained harmonia axyridis adults have higher reproductive capacity after eating green peach aphids.

Description

technical field [0001] The invention belongs to the technical field of insect feeding, and in particular relates to a feed for feeding larvae of Heterochromia larvae and a preparation method thereof. Background technique [0002] Currently, biological control is one of the most environmentally friendly pest control methods. With the rapid emergence of pest resistance, pesticide residues and unprecedented concerns about food safety, biological control methods are becoming more and more accepted and valued. Controlling pests through large-scale releases of natural enemies has had some success over the past few decades. Peach aphid, belonging to the order Hemiptera, is a wide-feeding pest that can damage various fruit trees such as pears, peaches, and plums, as well as various vegetable crops such as cabbage, cabbage, and pepper. The green peach aphid has a short life cycle and strong fecundity. It can cause harm to plants in various ways such as sucking plant juice through t...
