Tea geometrid larva artificial feeding feed and preparation method thereof

Abstract

The invention discloses tea geometrid larva artificial feeding feed, which is prepared from the following raw material ingredients in percentage by mass: 20 to 24 percent of dry enteromorpha prolifera powder, 1.5 to 3 percent of dry tea powder, 2.3 to 2.7 percent of agar powder, 0.2 to 0.5 percent of potassium sorbate, 0.4 to 0.8 percent of choline chloride, 0.5 to 1 percent of glucose and the balance of sweet potato starch production waste liquid. The artificial feed has the advantages that the preparation method is simple; the cost is low; the mildewproof and anti-corrosion effects are achieved; the feeding effect is superior to that of an ordinary artificial feed; the level similar to the natural feed can be reached. The larva cultured by the feed is healthy and strong; the quantity is large; the whole year successive transfer feeding can be realized; the goal of supplying tea geometrid standard sources in the whole year can be achieved.

Description

technical field [0001] The invention relates to the field of artificial breeding of pests, in particular to a feed for artificial breeding of tea geometrid larvae and a preparation method thereof. Background technique [0002] Tea geometrid is the most important leaf-eating pest in my country's tea gardens. It is widely distributed in various tea areas and affects the yield and quality of tea all the year round. In order to effectively control the harm of tea inchworms, the Institute of Tea began to study the use of tea inchworm nucleopolyhedrosis virus to control it in the 1980s. In 2005, the virus preparation obtained the registration license of biological pesticides and began to be widely used in tea gardens. Tea geometrid polyhedrosis virus has strong host specificity and good environmental compatibility. The preparation of polyhedrosis virus must first solve the problem of artificial large-scale feeding of tea geometrids. Natural feed (tea) is limited by many factors s...

AI Technical Summary

Problems solved by technology

The preparation of polyhedrosis virus must first solve the problem of artificial large-scale feeding of tea geometrids. Natural feed (tea) is limited by many factors such as seasons, and the cost is high. Fresh tea is not easy to store and easily rots and deteriorates. It needs to be replaced frequently, otherwise it is easy to cause larval diseases. , so it is necessary to carry out research on artificial feed and artificial feed feeding methods

Most of the existing artificial feeds still use tea as the main raw material and need to add a variety of vitamins and other nutrients. The cost is high, and the anti-mold and anti-corrosion ability is poor. Over time, the survival rate of larvae will be reduced, and it will not be possible to continue breeding, so it is difficult to meet the needs of insect sources
