Artificial feed for opisina arenosella walker larvae

Abstract

The invention discloses artificial feed for opisina arenosella walker larvae. Ingredients of the artificial feed for the opisina arenosella walker larvae comprise a main agent, an assisting agent, an antiseptic substance, a setting agent and water, wherein in parts by weight, the main agent comprises 10-14 parts of wheat germ flour, 4-5 parts of corn flour, 2.5-3.5 parts of cane sugar and 2.5-3.5 parts of beer yeast powder, the assisting agent comprises 0.7-0.8 part of Wesson salt, 0.1-0.15 part of cholesterol, 0.02-0.03 part of inositol and 0.02-0.04 part of choline chloride, the antiseptic substance comprises 0.3-0.4 part of sorbic acid, 0.02-0.04 part of p-hydroxybenzoic acid and 0.3-0.5 part of ascorbic acid, the setting agent comprises 1.25-1.75 parts of agar and 70-80 parts of water. The artificial feed for the opisina arenosella walker larvae has the advantages that nutrients are comprehensive, raw materials are available, the price is low, the cost is low, and a large number of test insect sources consistent in development are provided for technologies of intensive study of bioecology and insecticide toxicology of opisina arenosella walker and prevention and control of parasitic wasp through breeding of the opisina arenosella walker.

Description

technical field [0001] The invention relates to a feed, in particular to an artificial feed for coconut weaver moth larvae. Background technique [0002] Palmaceae is the second largest economic plant after Gramineae, which has important economic and ecological value. Coconut weaver moth Opisina arenosella Walker is an important pest newly invaded on palmaceae in my country. The Chinese names are coconut black-headed caterpillar, leaf-eating caterpillar, coconut borer moth and coconut wood moth, which belong to Lepidoptera. Because its taxonomic status has not yet been determined, different scholars often place it in Xyloryctidae or weaving moth. In the moth family Oecophoridae. Coconut weaver moths usually cause damage to the larvae of palm plants by feeding on the epidermis of the leaves. They spin and curl the leaves and stick the feces to form long insect passages, which can cause the leaves of palm plants such as coconuts to wither and sag. The leaves of the whole plan...

AI Technical Summary

Problems solved by technology

However, the stacking of multi-layer host leaves makes the microenvironment for the growth of the coconut moth closed and airtight, and the test insects are extremely susceptible to pathogenic bacteria.

And because most palm plants are tall, it is very difficult to collect leaves artificially

Causes disadvantages such as high feeding cost, low feeding efficiency, cumbersome operation, etc.
