Citrus fruit fly artificial-feed and preparation method thereof

Abstract

The invention relates to a citrus fruit fly artificial-feed and a preparation method of the citrus fruit fly artificial-feed. At present, no citrus fruit fly artificial-feed for controlling multiple indexes such as pupation rate, larval stage, pupal weight, female-male ratio, single-female egg laying amount and egg hatchability of citrus fruit flies is invented in domestic. The citrus fruit fly artificial-feed disclosed by the invention comprises the following components in percentage by mass: 10-15% of sucrose, 3-10% of yeast powder and 20-27% of wheat bran, and the mass sum of the sucrose, the yeast powder and the wheat bran accounts for 40% of the mass of the citrus fruit fly artificial-feed. The preparation method comprises the following steps of: mixing sucrose, yeast powder and part of a preservative; adding water into the obtained mixture, uniformly stirring the obtained product, heating the obtained product in a water bath for 20 minutes at the temperature of 70 DEG C, and stirring constantly; after the obtained object is cooled, adding the rest of the preservative and a pH regulator, and uniformly stirring the obtained mixture; and adding wheat bran into the obtained product so as to obtain a finished product. The citrus fruit fly artificial-feed disclosed by the invention is easily available in raw materials, and can control the indexes such as pupation rate, larval stage, pupal weight, female-male ratio, single-female egg laying amount and egg hatchability of citrus fruit flies.

Description

technical field [0001] The invention relates to an artificial feed and a preparation method thereof, in particular to an artificial feed for Bactrocera dorsalis and a preparation method thereof, belonging to the field of feed. Background technique [0002] Bactrocera dorsalis is an economical insect that is extremely harmful to fruits and vegetables. In order to study the needs of ecology and control technology, since Finney successfully prepared artificial feed for Bactrocera dorsalis larvae with fresh carrots and other raw materials for the first time, the research on its feed formula has been nearly 60 years, and most of them have focused on the replacement of feed fillers and the formulation of raw materials. Than study two aspects. Practice has proved that an ideal feed filler should not only provide a suitable feed texture for fruit fly larvae, but also effectively address the nutritional needs of the feed. Some studies have concluded that sterols in wheat bran are es...

AI Technical Summary

Problems solved by technology

[0004] There are also some relatively good artificial feeds for Bactrocera dorsalis now, such as the full-text database of Chinese excellent master's degree theses, the first phase in 2011, pages 25-26, 69-70, a kind of artificial feed for Bactrocera dorsalis is disclosed, The raw material requirements of the Bactrocera dorsalis artificial diet are relatively general, and the amount of raw materials is not scientific enough to effectively control the pupation rate, larval duration, pupa weight, sex ratio, egg production per female and egg hatching of Bactrocera dorsalis. rate and other indicators

[0005] At present, there is no raw material that is easy to obtain in China, has strong imitability, and can effectively control the pupation rate, larval duration, pupa weight, sex ratio, single female egg production and egg hatching rate of Bactrocera dorsalis. Bacteralis dorsalis artificial diet with multiple indicators and preparation method thereof
