Embodiment 1

[0031] S1. When the weather is fine, prepare a formula (attraction material) containing a specific concentration of nicotine. The formula containing a specific concentration of nicotine is composed of the following components in weight percentage: bran 90%, imported fish meal 10% , adjust the above formulation to a humidity of 70% with a nicotine aqueous solution with a mass percent concentration of 1‰.

[0032] S2. Put the prepared ingredients above into a square plastic basin per 1 kg (length*width*height=45cm*30cm*12cm). At 8:00 in the morning on the same day, the plastic pots with formula materials were placed next to a domestic garbage dump, and at 17:00 in the afternoon, the plastic pots were taken back and brought back to the indoor cultivation.

[0033] S3. Under indoor conditions (temperature 25°C, humidity 30%), after the larvae were cultured for 20 days, the culture basin was placed in a larger plastic basin filled with dried bran powder, and the black soldier fly l...

Embodiment 2

[0037] Other operations are the same as in Example 1, except that the formula is composed of the following components by weight percentage: 90% bran, 10% imported fish meal, and the above formula is adjusted to The humidity is 70%.

[0038] Finally, black fingered soldier fly larvae that are 20-25 days old, weigh 0.10-0.16 g per larvae, plump and black in color are selected, and these black fingered soldier fly larvae are allowed to pupate and emerge naturally at room temperature. After that, the nicotine-resistant black fingered soldier fly species can be obtained.

Embodiment 3

[0040] Others are the same as in Example 1, except that the formula is composed of the following components by weight percentage: 90% of bran, 10% of imported fish meal, and the above formula is adjusted to the humidity with a nicotine aqueous solution with a mass percentage concentration of 2.0‰ 70%.

Abstract

The invention relates to the technical field of animal variety screening and particularly discloses a formula material for trapping wild ptecticus tenebrifer to lay eggs and a screening method of nicotine-resistant ptecticus tenebrifer varieties. The formula material comprises the following components in percentage by weight: 70-90% of bran and 10-30% of imported fish meal; and the humidity of the formula material is regulated to 70% by using a nicotine water solution with the concentration of 0.1-0.2%. By using the formula material obtained by directly and scientifically matching the nicotine water solution with proper concentration, the bran and the imported fish meal, the bad smell and bitter taste of nicotine are successfully covered, and the wild ptecticus tenebrifer is effectively trapped to lay eggs; in addition, due to the propriety and certainty of nicotine content, the nicotine resistances of ptecticus tenebrifer obtained by using different batches of formula materials with the same weight are kept basically same in the same trapping environment, and a stable screening effect is achieved.

Description

technical field [0001] The invention relates to the technical field of animal species screening, in particular to a formula for trapping wild black soldier flies to lay eggs and a screening method for nicotine-resistant black soldier flies. Background technique [0002] Unsuitable fresh tobacco leaves refer to fresh tobacco leaves (moisture content 80-90%) that are not suitable for flue-cured tobacco production, and the waste or low-grade tobacco leaves (moisture content about 15%) produced during the production process of flue-cured tobacco mentioned in the literature. different. Unsuitable tobacco leaves usually refer to the lower and upper leaves that are not suitable for the cigarette industry and need to be removed in the field after the tobacco plants are normally capped and 2 to 3 milk foot leaves are removed, mainly including the bottom of the tobacco plants due to insufficient light and stunted growth , 2 lower leaves with insufficient inclusions, expected poor qua...
