Artificial feed for melon fly larvae

Abstract

The invention discloses an artificial feed for melon fly larvae, which comprises the following ingredients: a main agent, a filling agent, a preservative, an acidity regulator and water, wherein the main agent comprises beer yeast and sugar; the filling agent comprises wheat bran, fine corn particles and sanitary pulp; the preservative comprises methyl parahydroxybenzoats; the acidity regulator comprises hydrochloric acid and an alkaline neutralizing agent or an acidic neutralizing agent. The artificial feed disclosed by the invention is simple and efficient in melon fly larvae formula, affordable, practical and easy to operate, completely solves the technical problem of widely artificially feeding melon fly larvae in melon fly rooms, promotes the smooth research on steaming and quarantine inspection treatment measures for tropical fruits such as exported fresh fruit pawpaw and the like, provides an important technical support for the export sale of fresh fruits such as pawpaw in out country, significantly promotes the research and the development of artificial feed for melon flies in China, and provides a large amount of important larvae sources for various future scientific researches on melon flies, and therefore, the artificial feed has significant ecological, economic and social benefits.

Description

technical field [0001] The invention belongs to the field of agricultural biotechnology, and in particular relates to an excellent artificial feed formula for fruit fly larvae. Background technique [0002] Bactrocera cucurbitae Coquillett, commonly known as needle bee, larvae called melon maggot, belongs to Diptera, Tephritidae Tephritidae, oligomane Bactrocera subfamily Dacinae, fruit fly genus Bactrocera Macquart. Melon fly was first reported in India in 1913, and it is now widely distributed in more than 30 subtropical countries and regions. In my country, it is mainly distributed in Guangdong, Guangxi, Hainan, Fujian, Yunnan, Taiwan and other regions. It has a wide range of hosts, up to more than 120 kinds of plants, mainly damaging Cucurbitaceae and Solanaceae plants, such as melon, cucumber, bitter melon, etc. The female adults of Bacteria melons use their ovipositors to pierce into the skin of young melons to lay eggs, causing coagulation and flow of glue at the punc...

Problems solved by technology

However, because natural feed is limited by factors such as seasons and easy to rot and deteriorate, it is becoming more and more important to explore the artificial feed formula of Bacteralis melons, scientifically raise Bacteralis melons, and solve the seasonal shortage of Bacteralis melons

[0004] The research of fruit fly larvae artificial feed, foreign research is relatively earlier is the larvae artificial feed that Finney forms with fresh carrot, sucrose, torula yeast, antibiotic, but feed is polluted by microorganism easily; Chang studies beer yeast, sucrose, antibacterial agent and Citric acid is made into liquid feed to feed the fruit flies, and wheat germ oil is added to the liquid artificial feed to raise several types of fruit fly larvae, but the supply of this wheat germ oil is insufficient in the market, and the price is relatively high

In China, most of the researches in this area focus on the artificial diet of Bactrocera dorsalis larvae, but there are few researches on the formula of artificial diet for Bactrocera dorsalis larvae, and the formula currently used in China cannot provide comprehensive nutrition for the development of Bactrocera dorsalis , large-scale artificial breeding cannot be carried out indoors, and there are problems of mildew and peculiar smell in the later stage of breeding, which seriously corrodes laboratory equipment and affects the health of laboratory personnel.

For example, in China, a single wheat bran is currently used as a medium, and sucrose and yeast are added to form an artificial feed for larvae. The artificial rearing of the fruit fly is carried out. The egg hatching rate is low, and many larvae are relatively small. There are great differences in the natural state, and it is difficult to provide a large number of insect sources with consistent development and reliable quality. Moreover, in the later stage of rearing, artificial feed is polluted, rotten and mildewed, and produces a heavy odor, which can easily lead to a large number of reared larvae. death, thereby affecting various scientific studies of the fruit fly
