Embodiment 1

[0026] S1. When the weather is fine, prepare unsuitable fresh tobacco leaf formula (attractive aggregate). The unsuitable fresh tobacco leaf formula contains the following components in weight percentage: unsuitable fresh tobacco 30%, bran 60%, imported fish meal 5%, soybean meal 5%. The humidity of the formula is adjusted to about 65% by adding a certain amount of tap water.

[0027] S2. Put the above prepared formula into a square plastic basin (length*width*height=45cm*30cm*12cm) per 1 kg. At 8:00 am of the same day, the plastic pots containing the formula were placed next to a domestic garbage pile, and the plastic pots were taken back at 17:00 in the afternoon and brought back to indoor cultivation.

[0028] S3. Under indoor conditions (temperature 25℃, humidity 30%), cultivate the trapped wild fly eggs until the larvae mature, spread the culture material on a 10-20 mesh screen, and place the screen in the sun , Put a plastic basin under the screen, and the fly maggots are a...

Embodiment 2

[0032] S1. When the weather is fine, prepare unsuitable fresh tobacco leaf formula (attractive aggregate). The unsuitable fresh tobacco leaf formula contains the following components by weight: 40% unsuitable fresh tobacco, 50% bran, and imported fish meal 10%. The humidity of the formula is adjusted to about 65% by adding a certain amount of tap water.

[0033] S2. Put the above prepared formula into a square plastic basin per 1.2 kg (length * width * height = 45cm*30cm*12cm). Put the plastic pots containing the formula in a chicken farm at 8:00 am of the same day, take back the plastic pots everywhere at 17:00 in the afternoon, and bring them back indoors for cultivation.

[0034] S3. Under indoor conditions (temperature 28°C, humidity 40%), cultivate the trapped wild fly eggs until the larvae mature, spread the culture material on a 10-20 mesh screen, and place the screen in the sun , Put a plastic basin under the screen, and the fly maggots are afraid of light and drill out f...

Embodiment 3

[0038] S1. When the weather is fine, prepare unsuitable fresh tobacco leaf formula (attractive aggregate), and the unsuitable fresh tobacco leaf formula contains the following components in weight percentage: unsuitable fresh tobacco leaf 50%; bran 40%; soybean meal 10 %. The humidity of the formula is adjusted to about 65% by adding a certain amount of tap water.

[0039] S2. Put the above prepared formula into a square plastic basin (length*width*height=45cm*30cm*12cm) every 1.5 kg. Put the plastic pots containing the formula in a pig farm at 8:00 am of the same day, and take back the plastic pots at 17:00 in the afternoon and bring them back indoors for cultivation.

[0040] S3. Under indoor conditions (temperature 30°C, humidity 60%), cultivate the trapped wild fly eggs until the larvae mature, spread the culture material on a 10-20 mesh screen, and place the screen in the sun , Put a plastic basin under the screen, and the fly maggots are afraid of light and drill out from t...

Abstract

The invention relates to the technical field of screening of animal species, in particular to a screening method for nicotine-resistant housefly species. The screening method comprises the steps that specific materials of a non-applicable fresh tobacco leaf formula are utilized to trap wild houseflies to come around to lay eggs, larvas of the wild houseflies are cultivated to a mature state, and the housefly species resistant to nicotine are screened according to growth and development indexes of the larvas. According to the screening method, the specific materials of the trapping formula are utilized, and therefore the housefly species effectively resistant to the nicotine can be screened out.

Description

Technical field [0001] The invention relates to the technical field of animal breed screening, in particular to a method for screening nicotine-resistant housefly breeds. Background technique [0002] Housefly is an important economical insect and environmentally friendly insect. Housefly can be used to dispose of various decaying organic wastes, such as beer pomace, bean dregs, chicken manure, pig manure and kitchen waste. Existing housefly species have good biological treatment capacity for non-toxic organic waste, but the treatment effect of fresh tobacco leaves is not good, because fresh tobacco leaves contain a certain amount of toxic substances such as nicotine, Housefly larvae (Housefly maggots) have certain toxic effects and inhibit growth. [0003] Unsuitable fresh tobacco leaves refer to fresh tobacco leaves that are not suitable for flue-cured tobacco production (80-90% moisture content), and the waste or low-level tobacco leaves produced during the flue-cured tobacco p...
