Embodiment 1

[0039] Example 1 Screening of nicotine-resistant Chrysalis chrysalis species from wild Chrysocephala species

[0040] S01. When the weather is fine, prepare the trapping culture material, which is composed of the following components in weight percentage: bran 85%, imported fish meal 15%, and the above-mentioned nicotine aqueous solution with a mass percentage concentration of 1‰ The formulation is adjusted to a humidity of 60%.

[0041] S02. Put the culture material prepared above into a square plastic pot per 1 kg (length*width*height=45cm*30cm*12cm). At 8:00 in the morning on the same day, the plastic pots containing the culture material 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.

[0042] S03. Under indoor conditions (temperature 25°C, humidity 30%), cultivate the trapped wild fly eggs until the larvae are mature, and use the behavior of the fly larvae during the...

Abstract

The invention discloses a cultivating method of a nicotine-resisting chrysomyia megacephala strain. According to the cultivating method, chrysomyia megacephala fly blows of the nicotine-resisting chrysomyia megacephala strain are inoculated into first formula materials containing nicotine, the fly blows are cultivated until larvae are ripe and pupate, after fly pupae are subjected to emergence, second formula materials are used for feeding adults, after the adults carry out oviposition, a next-generation domestication cultivating is carried out, and by continuous domestication cultivating of 20-30 generations, the stable nicotine-resisting chrysomyia megacephala strain can be obtained. The first formula materials comprise, by weight, the components of 70%-85% of bran and 15%-30% of imported fish meal, and a nicotine water solution with the mass percent concentration of 0.3% is used for adjusting the humidity of the formula materials into 60%. According to the method, the nicotine water solution with the proper concentration is directly used for being combined with the bran and the imported fish meal in a scientific mode, the obtained first formula materials successfully cover the unpleasant smell and bitter taste of nicotine, nutrient components are proper, smooth growing of the chrysomyia megacephala larvae is guaranteed, due to the proper and certain nicotine content, the fact that the obtained chrysomyia megacephala maggot rates of the formula materials with the same weight combination in different batches under the same cultivation environment are basically the same is guaranteed, and a stable cultivating effect is obtained.

Description

technical field [0001] The invention relates to the technical field of insect breeding, in particular to a method for cultivating a nicotine-resistant strain of Chrysocephala macrocephala. 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 quality after roasting, and no roasting value, and 2 to...
