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 60% 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 fly maggots were cultivated for 4 days, the culture basin was placed in a larger plastic basin filled with dried bran powder, and Lucilia sericata ...

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 60%.

[0038] Finally, 4 to 5 days of maturity, each maggot weighing 0.03 to 0.05 g, plump body, and golden color are selected. At room temperature, these maggots are allowed to pupate and emerge naturally. Obtain nicotine-tolerant Lucilia sericata species.

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‰ 60%.

Abstract

The invention relates to the technical field of animal variety screening, in particular to a formula for trapping wild Lucila sericata to lay eggs and a screening method for nicotine-resistant Lucilia sericata varieties. The formula is composed of the following components by weight percentage: 70-90% of bran, 10-30% of imported fish meal, and the above-mentioned formula is adjusted to a humidity of 60% with a nicotine aqueous solution with a mass percentage concentration of 1‰-2‰. %. The present invention directly adopts the scientific compatibility of nicotine aqueous solution with appropriate concentration, bran and imported fish meal. The appropriateness and certainty of the alkali content ensure that in the same trapping environment, the nicotine resistance of Lucilia sericata obtained from different batches of formula materials with the same weight composition is basically the same, and a 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 trapping wild Lucilia sericata to lay eggs and a screening method for nicotine-resistant Lucilia sericata species. 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 q...
