[0040] 3. Preparation of the semi-artificial feed for the firefly beetle

[0041] According to the optimized formula of the semi-artificial diet for the phoenix firefly beetle, each component was weighed separately. Agar, distilled water (350ml) as group X; wheat germ, oatmeal, casein, sucrose, cholesterol, choline chloride, distilled water (50ml) as group Y; yeast, Webster's salt, sitosterol, ragweed leaf powder , fly maggot powder, soybean oil, olive oil, Nibelkin, formaldehyde, sorbic acid, vitamin mixture, yeast, sodium ascorbate, 10% KOH, distilled water (100ml) are Z group.

[0042] Step 1: Soak the agar in group X in distilled water and heat it in a microwave to dissolve the agar completely.

[0043] The second step: the mixture in group Y is then slowly added to group X, and fully stirred (the ingredients in group Y are mixed and stirred evenly in advance, and completely dissolved in distilled water for later use).

[0044] Step 3: When the temperature of the above m...

Embodiment

[0047] According to the optimized formula of semi-artificial diet for adults of firefly beetle:

[0048] 1) Weigh 11.6g of agar, 0.8g of methyl benzoate, 672ml of distilled water, 0.8ml of formaldehyde, 22g of wheat germ, 0.5g of sorbic acid, 26g of casein, 11g of ragweed powder, 26g of sucrose, 0.4g of vitamin mixture, cholesterol 0.05g, 10% KOH 8ml, Webster's salt 7.4g, fly maggot powder 0.02g, soybean oil 0.2ml.

[0049] 2) Soak the agar in distilled water (350ml), and heat it in a microwave oven to completely dissolve the agar;

[0050] 3) Then mix wheat germ, oatmeal, casein, sucrose, cholesterol, choline chloride, etc. into distilled water (50ml), stir well to dissolve completely in distilled water, then pour into agar solution and stir evenly, leave the heating source ;

[0051] 4) When the temperature of the above mixture drops to 50°C, add evenly mixed yeast, Webster's salt, sitosterol, ragweed leaf powder, fly maggot powder, soybean oil, olive oil, Niberkin, formal...

Abstract

The invention relates to semi-artificial diet of ophraella communa Lesage, the natural enemy of exotic ragweed, and a preparation method thereof, which belong to the field of biological control, and the semi-artificial diet of ophraella communa Lesage subsequently comprises the following 8 key components: wheat germ, 10 percent of KOH, glucose, nipagin, ragweed leaf powder, agar, cholesterol and soybean oil; the 8 key components which affect the growth of ophraella communa Lesage larvae are as follows: oatmeal, agar, wheat germ, glucose, choline chloride, 10 percent of KOH, distilled water and soybean oil. In the preparation process of the semi-artificial diet, the preparation of the ragweed leaf powder, the sequence of all the components in preparation, the preparation method and the sterilization and storage methods are standardized, so as to feed and reproduce ophraella communa Lesage, the natural enemy of exotic ragweed in a large scale.

Description

1. Technical field [0001] The invention relates to a formula and a preparation method of a natural enemy of invasive organisms (ragweed)——Ophraella communa LeSage semi-artificial feed, which belongs to the field of biological control of harmful organisms, and is specially used for large-scale breeding of breeding pests. The natural enemy of grasses, the broad-cutter firefly beetle, can replace the large-scale breeding of the plant-dependent plants or the shortage of seasonal plants. 2. Background technology [0002] Ragweed, Ambrosia artemisiifolia, is native to North America and is a widespread worldwide weed. It invaded our country in the 1930s, and spread its hazards to the surrounding areas through the four diffusion centers of Shenyang, Nanjing, Wuhan, and Nanchang. It has now spread to more than 20 provinces, municipalities, and autonomous regions in Northeast, North, Central, and East China. . The pollen of ragweed can cause people's allergic reaction - "hay fever"....
