preparation example Construction

[0021] Such as figure 1 As shown, the preparation method of the heterochromia larva feeding feed provided by the embodiments of the present invention comprises the following steps:

[0022] S101: passing the pig liver powder through a double-layer 100-mesh gauze to remove larger particles to obtain very fine pig liver powder;

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

[0024] S103: 3 parts of sucrose, 1.5 parts of honey and 0.02-0.03 parts of potassium sorbate are fully dissolved in 15 parts of water;

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

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

[0027] S106: Divide the obtained artificial feed into 1....

Embodiment 1

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

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

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

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

[0035] (5) Divide the Heterochromia artificial diet obtained in (4) into 1.5ml centrifuge tubes, and store in a -20°C refrigerator.

[0036] (6) According...

Embodiment 2

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

[0039] (2) Preparation of β-carotene solution: Add 0.45g β-carotene to a 10ml centrifuge tube filled with 1g linseed oil + 1.5g olive oil, place it in an ultrasonic cleaner for 2min, fully dissolve β-carotene white.

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

[0041] (4) Mix 15g of p...

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...
