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 by 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 golden soldier fly ...

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, 20-25 days old golden soldier fly larvae with a weight of 0.10-0.16 g per larvae, plump body and jet-black color were selected, and these golden soldier fly larvae were allowed to pupate and emerge naturally at room temperature. After that, the nicotine-resistant Golden 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 screening of animal varieties, and particularly relates to a formula for trapping wild ptecticus aurifer for spawning and a screening method of nicotine-resisting ptecticus aurifer variety. According to the formula, the product comprises the following components in percentage by weight: 70-90 percent of bran and 10-30 percent of imported fish powder, and the components are blended by using a nicotine water solution with a mass percent concentration of 0.1-0.2 percent until the humidity is 70 percent. According to the formula, the nicotine water solution with the proper concentration is directly adopted to be scientifically combined with the bran and the imported fish meal, the obtained formula successfully covers the smell and the bitter taste of the nicotine, and thus the wild ptecticus aurifer is effectively trapped for spawning; meanwhile, because of appropriateness and certainty of the nicotine content, the nicotine resistance capabilities of the wild ptecticus aurifer larva, obtained by different batches and same weights of the components are basically the same in the same trapping environment, and the stable screening effect is obtained.

Description

technical field [0001] The invention relates to the technical field of animal species screening, in particular to a formula for luring wild golden soldier flies to lay eggs and a screening method for nicotine-resistant golden 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...
