Embodiment 1
[0044] Use this method:
[0045] ①In August 2014, 5 pairs of paired adults (≤24h) that emerged on the same day were selected, put into an octagonal bottle filled with 10% honey water absorbent cotton, sealed with a gauze of about 40 mesh, and covered with a gauze outside the bottle mouth. A piece of filter paper with a diameter of 12.5 cm is placed on top of the filter paper and covered with a petri dish (the diameter of the petri dish is 12 cm) to collect and count the ovum mass on the same day.
[0046] ②Put the filter paper with the egg mass into the artificial climate box (breeding conditions: 27°C, relative humidity: 75%, within 24 hours a day, turn on the light and light time: turn off the light and dark time is 12:12), and cultivate until the 7th day. Day, about 90% of the larvae hatch. Use a writing brush to hold the silk spitting out of the newly hatched larvae and put them into glass finger tubes filled with feed (1 larva per tube, 40 tubes in total), and seal with ...
Embodiment 2
[0051] In September 2014, the content of Example 1 was repeated.
Embodiment 3
[0053] In October, 2014, the content of embodiment 1 was repeated again.
[0054] The results are shown in Table 1
[0055] Table 1
[0056]
[0057] in conclusion:
[0058] (1) Through this method, a large number of required egg masses can be collected to meet the needs of various related experiments and experiments; the daily egg production and single female egg production of the wheat moth can be accurately counted, and the error rate of the results is compared with the actual results Much lower than previous methods, with a higher accuracy.
[0059] (2) By this method, the whole generation of wheat moth can be completely completed, (the generation of wheat moth is exactly the whole life of wheat moth, and its whole life has experienced: egg, larva, pupa, adult four worm states).
[0060] (3) Through the feeding method of perspective, during the feeding process of the wheat moth, the behavior and growth and development process of eggs, larvae, pupa, and adults of the ...

Abstract
The invention provides an artificial breeding method of gelechiid moths. The method comprises the adult-stage egg mass collecting stage, the larval-stage and pupal-stage breeding stage and the adult-stage breeding stage. The artificial breeding method of the gelechiid moths is characterized in that imagoes have the habit of climbing upwards and the habit of tending to gaps for oviposition, egg masses of the gelechiid moths are collected by providing proper gaps and using a gland filter paper method, the daily oviposition amount and the amount of single female adult oviposition of the gelechiid moths can be conveniently and accurately counted, and damage to the egg masses can be effectively avoided through the method for collecting the egg masses; hatched larvae have the habit of silking drooping, the larvae are directly inoculated into finger-shaped tubes through a writing brush in a wire hanging mode, and harm to newly hatched larvae in the larva inoculating process can be effectively avoided; in the larva and pupa breeding process, completely transparent finger-shaped single-way glass tubes and corresponding feed and sealing technology are well-chosen, and tracking observation of a researcher on the larvae and the pupae of the gelechiid moths can be well met.
Description
technical field [0001] The invention relates to a method for raising animals, in particular to a method for artificially raising wheat moths. Background technique [0002] Wheat moths belong to the order Lepidoptera, the family Wheat Mothidae, and the genus Wheat Moth. The insect can harm a variety of food crops, such as rice, wheat, corn, sorghum, etc., as many as 19 species, with multiple generations in a year, harming the grain germ and seriously affecting its germination ability. Most of them are bored into empty shells, with an average loss of about 13.1%-24%. They are important stored grain pests. Scholars at home and abroad have done a lot of research on the wheat moth, but because the living place of the insect is hidden, the research on its biological characteristics is not perfect, especially the growth and development process of the wheat moth is not very clear, which affects the effective control of the wheat moth . [0003] At present, various natural enemy i...
