Problems solved by technology

In this method, rice, barnyardgrass, wheat and other feed plants are planted in pots with soil to raise SBPH. The disadvantage is that the feeding cycle is long and limited by conditions such as temperature and site, it is not easy to raise SBPH in large quantities, and the feed plants need to be replaced. It is inconvenient to operate and transfer insect sources, and it will lead to inconsistent developmental periods of SBPH, resulting in wing type differentiation, which is difficult to meet the experimental requirements.
Third, Insect Knowledge, 2008, 45(2): 314-317, a simple method for raising SBPH indoors, Zhang Aimin and Liu Xiangdong, using sponge as a medium and using plastic boxes to cultivate rice seedlings for SBPH breeding, using a single Seedlings are raised at the same age by single-head breeding method. The rice seedlings cultivated by this method are prone to root rot without seed dis...

Embodiment 1

[0022] (1) Cultivate barley seedlings: take the plump barley seeds and use carbendazim wettable powder with a weight concentration of 50% first, and sterilize the seeds by dressing them at 0.3% of the weight of the seeds for 4 hours, then rinse them with clean water, and pour them into the shop. Cover the cultured ceramic tray with moist absorbent paper, cover it with gauze, and place it in a light incubator at a temperature of 28°C to accelerate germination. After 2 days, use tweezers to pick out the white barley seeds, and put them into the wide mouth that has been covered with two layers of moist absorbent paper. In the bottle, it is advisable to cover the bottom of the bottle. Pay attention to leaving a certain gap between the seeds. After planting, cover the bottle mouth with gauze and fix it with a rubber band. Continue to put it in the bottle at a temperature of 28°C, a relative humidity of 70%, and a light time of 12 hours. , in a light incubator with a light intensity ...

Embodiment 2

[0027](1) Cultivation of barley seedlings: take the plump barley seeds first with 75% thiophanate-methyl wettable powder, and sterilize the seeds by dressing 0.05% of the weight of the seeds for 8 hours, rinse with clear water, pour into In a culture ceramic plate covered with moist absorbent paper, covered with gauze, placed in a light incubator with a temperature of 25 ° C to promote germination. After 2 days, use tweezers to pick out the white barley seeds and put them in a wide area that has been covered with two layers of moist absorbent paper. In the bottle, it is advisable to cover the bottom of the bottle, and pay attention to leave a certain gap between the seeds. After planting, cover the mouth of the bottle with gauze and fix it with a rubber band. Continue to put it in the temperature of 25 ° C, the relative humidity of 80%, and the light time of 14 hours, in a light incubator with a light intensity of 5500 LUX, for about 5 days, when the barley grows to 4-5 cm, it ...

Embodiment 3

[0032] (1) Cultivation of barley seedlings: take the plump barley seeds first with 75% thiophanate-methyl wettable powder, and sterilize the seeds by dressing seeds at 0.2% of the weight of the seeds for 6 hours, rinse with water again, pour into In a culture ceramic plate covered with moist absorbent paper, covered with gauze, and placed in a light incubator with a temperature of 22 ° C for germination. In the bottle, it is advisable to cover the bottom of the bottle, and pay attention to leave a certain space between the seeds. After planting, cover the mouth of the bottle with gauze and fix it with a rubber band. Continue to put it in the temperature of 22 ° C, the relative humidity of 90%, and the light time of 16 hours, in a light incubator with a light intensity of 5000LUX, about 5 days, when the barley grows to 4-5cm, it is used to raise the SBPH;

[0033] (2) Raising the nymphs of the SBPH: put the newly hatched nymphs of the SBPH into the wide-mouthed bottle of the cu...

Abstract

The invention relates to a method for raising small brown rice planthopper by utilizing soil-less cultured barley seedlings, belonging to the technical field of insect raising. The method comprises the steps of: culturing barley seedlings, raising small brown rice planthopper nymphae, taking care of the eggs delivered by small brown rice planthopper imagoes and carrying out subculture. In the invention, soil-less cultured barley seedlings are adopted, the culture is not limited by field, temperature and other natural conditions, and the seeds of barley seedlings are sterilized to prevent the barley seedlings from rotting. During the raising period, the whole operation is convenient, and the environment is clean and neat without the limitation of time, space and temperature, especially a method of inversely covering a wild-mouth bottle is used for transferring nymphae to reduce the natural death of nymphae during transferring; reasonable culture density is used for nymphae culture and imagoes culture, which ensures the fully utilization of barley seedlings, reduces the frequency for replacing barley seedling, facilitates the operation and saves time. The invention has the advantages of subculture, uniform worm age, large multiplication quantity and the like, and ensures the large quantities of standard worm source required by test.

Description

technical field [0001] The invention belongs to the technical field of insect rearing, and in particular relates to a method for feeding large quantities of brown planthoppers throughout the year. Background technique [0002] The brown planthopper, Laodelphax striatellus (Fallen), also known as the gray rice louse, is one of the important rice pests in the Yangtze River Basin and North China. The vector of disease and other diseases. In recent years, due to the influence of various factors such as changes in farming and cultivation systems, changes in control chemicals, and climate, the population density of SBPH has continued to increase in the Yangtze River Delta regions such as Zhejiang, Jiangsu, and Anhui, which not only caused serious losses in rice yields, but also spread rice stripes. Leaf blight, black-streaked dwarf and other viral diseases. With the aggravation of the harm of SBPH, the research work of SBPH has also attracted much attention. In order to conduct...
