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 85% and imported fish meal 15% , 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 the big-headed...

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: bran 85% and imported fish meal 15%, and the above formula is adjusted to The humidity is 60%.

[0038] Finally, 4-5 days old and mature, each fly maggot weighs 0.05-0.07 g, plump body, and golden-colored golden fly maggots are selected. At room temperature, these large-headed golden fly maggots are allowed to pupate and emerge naturally. Obtain nicotine-tolerant Chrysocephala 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: bran 85% and imported fish meal 15%, and the above formula is adjusted to humidity with a nicotine aqueous solution with a mass percentage concentration of 1.5‰ 60%.

Abstract

The invention relates to the technical field of animal variety screening and particularly discloses a formula material for trapping wild chrysomyia megacephala to lay eggs and a screening method of nicotine-resistant chrysomyia megacephala varieties. The formula material is composed of the following components in percentage by weight: 70-85% of bran and 15-30% of imported fish meal; and the humidity of the formula material is regulated to 60% 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 chrysomyia megacephala is effectively trapped to lay eggs; in addition, due to the propriety and certainty of nicotine content, the nicotine resistances of chrysomyia megacephala 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 material for trapping wild Chrysophora chinensis to lay eggs and a screening method for nicotine-resistant Chrysophora chinensis varieties. 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 inclus...
