Embodiment example 1

[0028] Implementation Case 1: Preparation of 1717.5g artificial feed

[0029] Corn flour 150g; Yeast powder 60g; Soybean flour 100g; Amaranthus retroflexus leaf powder 100g; Glucose 75g; Sorbic acid 5g; Formaldehyde 2ml; Ascorbic acid 5g; Multivitamins 0.5g; Agar 20g;

[0030] The formula of multivitamins is as follows:

[0031] Niacin 0.175g, riboflavin 0.09g, thiamine 0.05g, folic acid 0.025g, pantothenic acid 0.125g, pyridoxine 0.025g, biotin 0.005g and cobalaminamide 0.005g.

[0032] Feed preparation method:

[0033] (1) Weigh each component according to the distribution ratio, and set aside;

[0034] (2) Stir corn flour, yeast powder, soybean powder, and amaranth leaf powder evenly into a triangular flask, and sterilize in a high-pressure steam sterilizer at 120°C for 2 hours. After the sterilization is completed, take it out for use As A component;

[0035] (3) Weigh glucose and sorbic acid in proportion, mix the two as component B, and mix component A and component ...

Embodiment example 2

[0048] Implementation case 2: The artificial feed of the present invention and the effect contrast test of natural feed corn leaf

[0049] 1. Test materials and methods:

[0050] (1) The source of the tested insects: the source of the tested insects came from the larvae of the two-spot moth with the same age collected in the field in Shijiazhuang City, Hebei Province.

[0051] (2) Test feed:

[0052] Natural Feed Corn Leaves: Fresh corn leaves obtained from growing corn indoors

[0053] Artificial feed: adopt the feed prepared in Example 1 of this application

[0054] (3) Test method: The breeding method of test insects refers to the method described in Example 1. Each treatment is repeated 3 times, and 120 larvae are used for each repetition. Adult eclosion rate and single female egg production. This experiment was completed in the laboratory of Millet Research Institute of Hebei Academy of Agriculture and Forestry Sciences from July 2010 to the end of December 2011.

Abstract

The invention relates to insect feed and a feeding technique, in particular to artificial feed for Athelis lepigone larvae, a preparation method for the artificial feed and a simplified feeding method using the feed. The artificial feed has the advantages that the formula components and the content are reasonable, the nutrient substances are comprehensive, Amaranthus retroflexus leaf powder is used for artificial insect feeding for the first time, the nutrient conditions required by Athelis lepigone to smoothly develop and complete the entire generation can be fully satisfied, and the indexessuch as development speed and survival rate of the larvae, pupa weight and egg laying amount of imagoes can be obviously improved.

Description

technical field [0001] The invention relates to insect feed and feeding technology, in particular to an artificial feed for the larvae of the spodoptera moth, its preparation method and a simplified feeding method using the feed. Background technique [0002] Two o'clock moth ( Athelis lepigone ) belongs to the Noctuidae family of Lepidoptera and is known to be distributed in China, Japan, Korea, Russia, Europe and other places. It is a new pest that has seriously harmed summer corn in the Huanghuaihai region of my country in recent years. In 2011, it has spread to 153 counties in 33 cities (prefectures) in 6 provinces, with an area of ​​more than 2.2 million hm 2 . Adult larvae of Spodoptera moth like to inhabit in shaded and hidden places, and have the habit of avoiding light. They mainly hide corn seedlings by hiding in the shredded wheat straw around the roots of plants or under the ground cover, resulting in lack of seedlings in the field, broken ridges and even destr...
