Ceratitis capitata larva feed capable of shortening hatching period

Abstract

The invention discloses ceratitis capitata larva feed capable of shortening hatching period. The ceratitis capitata larva feed is prepared from beer yeast, wheat bran, cane sugar, methyl parahydroxybenzoats, composite vitamins, berberine, coumarin and water. The ceratitis capitata larva feed has a good effect for shortening a larva developmental period and pupal period and increasing the pupation rate of ceratitis capitata larva and the eclosion rate of pupa after the larva turns into the pupa.

Description

technical field [0001] The invention belongs to the field of agricultural biotechnology, and in particular relates to a Mediterranean fruit fly larvae feed which can shorten the incubation period and a preparation method thereof. Background technique [0002] In recent years, with the continuous deepening of research on fruit fly biology, physiology, genetics, etc. and the development of control technology, a large number of uniformly developed insect sources are required, and due to seasonal restrictions, natural feed cannot be supplied year-round. [0003] For the first time in 1956, foreign scholar Finney successfully raised insects such as Bactrocera dorsalis and other insects with larval artificial feed composed of fresh carrots, sucrose, torula yeast, and antibiotics, but the feed was easily polluted by microorganisms; scholars such as Mitchell switched to dehydrated carrots in 1965. Bacteralis dorsalis was raised in large quantities by larvae artificial feed made of f...

Problems solved by technology

[0003] For the first time in 1956, foreign scholar Finney successfully raised insects such as Bactrocera dorsalis and other insects with larval artificial feed composed of fresh carrots, sucrose, torula yeast, and antibiotics, but the feed was easily polluted by microorganisms; scholars such as Mitchell switched to dehydrated carrots in 1965. Bacteralis dorsalis was raised in large quantities by larvae artificial feed made of flour instead of fresh carrots, but the cost was high; Vargas developed an artificial feed in 1983 with economical and practical wheat bran as filler, sucrose and yeast as the main agent, and successfully raised a large number of Bactrocera dorsalis

[0004] At present, domestic scholars Wang Yannian, Yuan Shengyong, Gao Qiang, Li Lili and other scholars have achieved certain research results on the artificial diet of Bactrocera dorsalis larvae, but their formula only uses wheat bran or some other material as a single filler, and the above formula is used The larvae are raised on artificial feed, and the physical properties of the feed, including shape, hardness, water content, and uniformity, cannot well meet the requirements for the healthy development of the larvae. Odor, easy to corrode experimental equipment, damage the health of operators
