[0018] Its modulation method of above-mentioned feed formula is:

[0019] Step 1: Weigh 3.0 g of yeast powder, 10.2 g of sucrose, and 0.1 g of methyl p-hydroxybenzoate according to the specific proportion of the formula;

[0020] Step 2: Add weighed 55ml of water, mix and stir evenly, cook in a 70°C water bath for 20 minutes while stirring continuously;

[0021] Step 3: After cooling, add 0.1g of sodium benzoate, 8.8g of wheat bran powder, and 0.4g of citric acid in sequence, and stir evenly;

[0022] Step 4: Add 16.0 g of wheat bran, stir while adding, and after mixing evenly, artificial feed for Bactrocera dorsalis larvae can be obtained.

[0023] The feed of the invention adopts analytically pure citric acid to adjust the pH, an...

Embodiment 2

[0028] Bacteria dorsalis is raised in batches, and its feed formula can be yeast powder 6.0g; sucrose 11.1g; wheat bran powder 4.8g; wheat bran 18.0g; sodium benzoate 0.12g; methyl p-hydroxybenzoate 0.12g; citric acid 0.6g ; Water 65ml.

[0029] Its modulation method of above-mentioned feed formula is:

[0030] Step 1: Weigh 6.0 g of yeast powder, 11.1 g of sucrose, and 0.12 g of methyl p-hydroxybenzoate according to the specific proportion of the formula;

[0031] Step 2: Add 65ml of water that has been weighed, mix and stir evenly, cook in a 70°C water bath for 20 minutes, and keep stirring at the same time;

[0032] Step 3: After cooling, add 0.12g of sodium benzoate, 4.8g of wheat bran powder, and 0.6g of citric acid in sequence, and stir evenly;

[0033] Step 4: Add 18.0 g of wheat bran, stir while adding, and after mixing evenly, artificial feed for Bactrocera dorsalis larvae can be obtained.

Embodiment 3

[0035] Bacteria dorsalis was raised in batches, and its feed formula was yeast powder 9.2g; sucrose 10.8g; wheat bran powder 2.0g; wheat bran 18.0g; sodium benzoate 0.15g; methyl p-hydroxybenzoate 0.15g; citric acid 0.7g; 70ml of water.

[0036] Its modulation method of above-mentioned feed formula is:

[0037] Step 1: Weigh 9.2g of yeast powder, 10.8g of sucrose, and 0.15g of methyl p-hydroxybenzoate according to the specific proportion of the formula;

[0038] Step 2: Add 70ml of weighed water, mix and stir evenly, cook in a 70°C water bath for 20 minutes while stirring continuously;

[0039] Step 3: After cooling, add 0.15g of sodium benzoate, 2.0g of wheat bran powder, and 0.7g of citric acid in sequence, and stir evenly;

[0040] Step 4: Add 18.0 g of wheat bran, stir while adding, and after mixing evenly, artificial feed for Bactrocera dorsalis larvae can be obtained.

[0041] The major biological indicators of Bactrocera dorsalis after applying artificial feed of the...

Abstract

The invention discloses a preparation scheme and method of citrus fruit fly larva feed. Artificial feed is one of effective approaches for obtaining high-quality fruit flies for experimenting. Each part of feed internally contains 3.0-9.5g of yeast powder, 10.0-11.5g of cane sugar, 2.0-9.0g of wheat bran powder, 15.0-20.0g of wheat bran, 0.10-015g of sodium benzoate, 0.10-0.15g of methyl p-hydroxybenzoate, 0.5-0.8g of citric acid and 50-80ml of water. The scheme is improved on the basis of a foreign authoritative formula through sufficiently considering the material quality and nutrition problems; feeding evaluation indexes such as larva-to-pupa proportion, eclosion rate, larva and pupa calendar period and pupa weight are all relatively ideal; and the preparation scheme has the characteristics of low cost, easiness for obtaining raw materials, simplicity in preparation and the like.

Description

technical field [0001] The invention relates to the field of artificial feed for insects, in particular to a formula preparation scheme and a preparation method of a feed for Bactrocera dorsalis larvae. Background technique [0002] Bactrocera dorsalis is a quarantine pest that is extremely harmful to fruits and vegetables. It is mainly distributed in Southeast Asia, Pacific Islands and other regions. At present, with the global warming, the suitable range of Bactrocera dorsalis is rapidly expanding. The effective control of this insect, especially the research and development of new genetic control technologies such as SIT and transgene, requires a large number of practical fly. Bacteria dorsalis is bred in batches with artificial feed to obtain a source of tested insects with the same growth period and the same physiological activity, which is the premise to ensure that research and development can be carried out scientifically. [0003] Regarding the artificial diet of ...
