Embodiment 1

[0032] S1. When the weather is fine, formulate a formula material (trapping material) containing a specific concentration of nicotine, and the formula material containing a specific concentration of nicotine is composed of the following components by weight: 90% of bran and 10% of imported fish meal , the above-mentioned formula material is adjusted to a humidity of 60% with an aqueous solution of nicotine with a concentration of 1‰ by mass.

[0033] S2. Put the above prepared formula materials into a square plastic pot (length*width*height=45cm*30cm*12cm) per 1 kg. At 8:00 in the morning on the same day, the plastic pots containing the formula materials were placed next to a garbage dump, and at 17:00 in the afternoon, the plastic pots were collected and brought back to the indoor culture.

[0034] S3. Under indoor conditions (temperature 25°C, humidity 30%), after culturing the fly maggots for 4 days, place the culture pot in a larger plastic pot filled with dried bran powde...

Embodiment 2

[0038] Other operations are the same as in Example 1, except that the formula material is made up of the following components in percentage by weight: 90% of bran and 10% of imported fish meal, and the above-mentioned formula material is adjusted to Humidity is 60%.

[0039] Finally, 4 to 5 days old and mature, each fly maggot weighs 0.06 to 0.08 g, plump and golden color. At room temperature, let these brown-tailed fly maggots naturally pupate and emerge after eclosion. A nicotine-resistant species of B. chinensis can be obtained.

Embodiment 3

[0041] Others are the same as in Example 1, except that the formula material is made up of the following components by weight: 90% of bran and 10% of imported fish meal, and the above-mentioned formula material is adjusted to humidity with the nicotine aqueous solution of 2‰ of mass percent concentration. is 60%.

Abstract

The invention relates to the technical field of animal variety screening and particularly discloses a formula material for trapping wild boettcherisca peregrina to lay eggs and a screening method of nicotine-resistant boettcherisca peregrina 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 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 boettcherisca peregrina is effectively trapped to lay eggs; in addition, due to the propriety and certainty of nicotine content, the nicotine resistances of boettcherisca peregrina 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

[0001] technical field [0002] The invention relates to the technical field of animal species screening, in particular to a formula for trapping the newly hatched larvae of wild Sarina sarcophagus and a screening method for nicotine-resistant Sarina sarcae species. Background technique [0003] 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 inc...
