Description

technical field

[0001] The invention relates to the technical field of insect feed and feeding. Specifically, the invention relates to an artificial feed for Spodoptera litura, a preparation method thereof, and a method for raising Spodoptera litura. Background technique

[0002] Spodoptera litura Fabricius belongs to Lepidoptera and Noctuidae. It is harmful in most parts of the country, mainly in the south of the Yangtze River Basin. It is a kind of melon and vegetable in southern my country. important pests. The pest has a wide range of hosts and harms more than 120 crops. Spodoptera litura eats the leaves, flowers and fruits of plants with larvae, and eats a large amount of food. The excreted insect excrement pollutes vegetables. Loss.

[0003] Optimizing the artificial breeding technology of Spodoptera litura and providing a large number of healthy and well-developed test insects is the basis for the study of the pest's physiology, genetics, toxicology, and biological ...

Examples

Embodiment 1

[0042] The preparation of embodiment 1 artificial feed of the present invention

[0043] Prepare 1000g of artificial feed, the process is as follows:

[0044] Add 100ml of distilled water to 13g of agar, stir well and heat to boil. Add 500ml of distilled water to 81g of soybean powder, stir evenly and heat to boiling, then add 38g of wheat germ powder and 33g of yeast powder into the agar solution after heating and boiling, add 225ml of distilled water, stir evenly, and wait until the temperature drops to At 60° C., 2 g of ascorbic acid, 1 g of sorbic acid, and 2 g of methylparaben were added. Then add 3 g of antifungal agent and 2 ml of distilled water into the above mixture, wherein the antifungal agent is composed of phosphoric acid and propionic acid in a weight ratio of 1:6. Stir evenly, pour into the wells of the cell culture plate, cool for 30 minutes, and put it in a 4°C refrigerator for later use.
