Spodoptera frugiperda larva artificial feed, preparation method thereof and application of artificial feed

Abstract

The invention discloses a spodoptera frugiperda larva artificial feed which is prepared from, by weight, 250-400 parts of wheat germ flour, 80-130 parts of soybean protein powder, 30-35 parts of yeastpowder, 25 parts of agar, 0.2 part of compound vitamin B, 8-15 parts of cholesterol, 2-3 parts of sorbic acid, 10-15 parts of ascorbic acid, 5 parts of methyl p-hydroxybenzoate, 4 parts of formaldehyde, 0.1-0.5 part of penicillin and 1500 parts of distilled water. The invention further discloses a preparation method and an application of the spodoptera frugiperda larva artificial feed. By the aidof the scheme, the artificial feed is long in storage time and complete in nutrient component, and the preparation method of the feed is simple. The artificial feed has high practical values and popularization values in the technical field of artificial breeding of insects.

Description

technical field [0001] The invention relates to the technical field of artificial feeding of insects, in particular to an artificial feed for Spodoptera frugiperda larvae and a preparation method and application thereof. Background technique [0002] Spodoptera frugiperda, also known as fall armyworm, belongs to the genus Spodoptera in the family Noctuidae of Lepidoptera. It is an omnivorous pest native to tropical and subtropical regions of America. It has strong ability to migrate and disperse and reproduce , the harmfulness of binge eating and the difficulty of prevention and control. Spodoptera frugiperda damages a variety of crops, can harm more than 80 kinds of plants, and is fond of grasses. It is most likely to damage common crops such as corn, rice, wheat, barley, sorghum, and various ornamental plants (genus) such as chrysanthemums, carnations, and geraniums. , and even cause harm to apples, oranges, etc., and damage to corn seedlings can generally reduce producti...

Problems solved by technology

[0008] Third, insects eating different foods will lead to differences in physiological indicators, especially digestive physiological indicators, which is not conducive to toxicology, physiology and ecology experiments

[0009] Fourth, the method provided by the invention patent with the patent application number "201910155450.0" is cumbersome. During the breeding process, the larvae population needs to be raised to the 3-4th instar and then transferred to the insect rearing box for single-head rearing. However, the larvae of Spodoptera frugiperda are easy to Cannibalism is not suitable for group breeding, and the transfer of larvae needs to be replaced during the feeding process of the patented method, which is labor-intensive and time-consuming

Although the breeding method of "Folius frugiperda Indoor Artificial Feed Group Breeding Technology" uses glass insect culture tubes for single-head breeding, each glass tube needs to be plugged, which is also time-consuming and labor-intensive.
