Problems solved by technology

However, it is obvious that the growth of wheat and corn has obvious seasonality and a long cycle, and these two kinds of important food crops will consume a large amount of wheat and corn seedlings, thereby increasing the cost of feeding

Embodiment 1

[0027] like figure 1 As shown, the present invention provides a method for raising Spodoptera frugiperda in large quantities with forage as food, comprising the following steps:

[0028] Feeding material: aperture 120 mesh 40×40×40cm 3 Square insect cage, Erlenmeyer flask, beaker, watering can, fresh stems and leaves of Bamboo grass, honey, cotton balls, 75% alcohol, sterile coconut bran soil, tap water.

[0029] Raising method: 300 newly hatched larvae were placed on the young leaves of Bamboo grass in the cage, and raised in an indoor environment (temperature 25-30 °C). The newly hatched larvae gathered to feed on the mesophyll. Vase with the original Cinnamon and close to the original Vase for easy transfer of larvae to the new grass. The replaced stalks or debris are directly laid on the bottom of the cage and do not need to be cleaned of insect excrement. After the larvae grow to 4 instars, the old leaf grass can be directly added to the cage for them to crawl and feed...

Embodiment 2

[0031] like figure 1 As shown, the present invention provides a method for raising Spodoptera frugiperda in large quantities with forage as food, comprising the following steps:

[0032] Feeding material: Except for the soil without coconut bran, other materials are the same as those in Example 1 of the present invention.

[0033] Raising method: egg, larvae, adult feeding and management method are identical with the embodiment of the present invention 1, just pupa or prepupa show that after sterilization, do not cover coconut chaff soil, but put some wet water cotton balls (not dripping) in the spare position of the box Moisturizing.

Embodiment 3

[0035] like figure 1 As shown, the present invention provides a method for raising Spodoptera frugiperda in large quantities with forage as food, comprising the following steps:

[0036] Except that 500 newly hatched larvae were put in at the initial stage of feeding, other feeding materials and methods were the same as those in Example 1 of the present invention.

Abstract

The invention discloses a method for massively feeding spodoptera frugiperda larvae with pasture as foodstuff, the foodstuff for feeding the spodoptera frugiperda larvae is pasture pennisetum hydridum which is easy to obtain, the massively feeding method is mainly completed in an insect feeding cage, fresh pennisetum hydridum tender stems and tender slices are inserted into bottles to feed the spodoptera frugiperda larvae, and the spodoptera frugiperda larvae are fed into the bottles. Mature larvae can automatically climb into residue of stems and leaves at the bottom of the cage and excrement to pupate; cleaning the cage and collecting pupae in a plastic box, disinfecting with alcohol, moisturizing with coco coir soil or wet cotton balls, and placing the pupa box in the clean cage; after eclosion of adults, pennisetum hydridum leaves continue to be used for trapping the adults to lay eggs, then egg masses of the same day age are collected and transferred into a plastic box, after larvae are hatched, the larvae are fed with pennisetum hydridum in an insect breeding cage, or pennisetum hydridum with eggs is directly inserted into a bottle and moved into a new insect breeding cage to continue to be fed. According to the method, simple mass breeding of the spodoptera frugiperda by a population method is realized, the operation is simple, labor and cost are saved, the spodoptera frugiperda bodies are healthy, and a large number of test spodoptera frugiperda at the same age can be easily obtained.

Description

technical field [0001] The present invention relates to the field of agricultural and forestry biotechnology, in particular to a method for raising Spodoptera frugiperda in large quantities with forage as food. Background technique [0002] Royal bamboo grass, also known as king grass and king grass, is a perennial upright clump grass. The biomass of the imperial bamboo grassland is huge, and the biomass of the imperial bamboo grassland planted in the south can reach 400t / hm2. Royal bamboo grass is a C4 plant with high photosynthetic rate of leaves, rich in protein, minerals, vitamins and other nutrients, and good palatability. It has gradually become a new type of high-quality forage grass with great potential in my country. In addition, P. chinensis can play an important role in degraded soil remediation, sewage purification and invasive species management. It can efficiently enrich soil heavy metals, remove nitrogen and phosphorus, and replace invasive alien species. In...
