Problems solved by technology

[0007] The present invention solves the problem that the existing Plutella xylostella larvae feeding device cannot meet the total food intake of the larval growth stage of Plutella xylostella, the larvae have a small moving space, affects the growth of the larvae, and it is difficult to observe quickly at a close distance, and solves the problem of frequent replacement of leaves in the existing Plutella xylostella xylostella adult

experiment example 1

[0025] Experimental example 1: adopt the method described in the present invention and the raising device mentioned in the background technology to carry out the control experiment of raising, test method: each 30 ovums newly produced in diamondback moth within 6 hours after birth were respectively according to the method described in the present invention Raise with the raising method mentioned in the background technology. The development period and survival of eggs, larvae and pupae, pupae weight and adult life expectancy were compared between the two feeding methods.

[0026] Result of the test: the results are shown in Table 1-2. The results show that the rearing device and method of the present invention significantly improve aspects such as diamondback moth survival, lifespan, pupa weight, etc. than the original method, and the developmental duration of different stages of diamondback moth is higher than that of the original method. slightly shortened. After the invent...

experiment example 2

[0031] Experimental example 2: using plant nutrient solution in the method of the present invention and the existing method of cultivating cabbage leaves with clear water mentioned in the background technology, and comparing the growth of cabbage seedlings under the two methods of cultivating cabbage leaves.

[0032] Experimental method: 30 pieces of cabbage leaves with basically the same growth height (about 5 cm) and tenderness (tender green) were respectively cultured at the seedling stage of cabbage according to the method of the present invention and the existing method. Compare the subsequent growth of cabbage seedlings.

[0033] Experimental results: the results are shown in Table 3. The results show that the cultivation of cabbage leaves with plant nutrient solution in the method of the present invention can ensure better growth of cabbage leaves for a long time (about 9 days).

[0034] According to the requirements of the growth of cabbage leaves, the present inventio...

Abstract

The invention belongs to the technical field of Lepidoptera moth rearing, aims to solve the problems that the existing feeding devices for feeding the diamondback moths affect the growth of larvae, the diamondback moths are difficult to observe in close range, which causes the adult diamondback moths to escape and affect the adult life of diamondback moths, and the existing feeding devices do not benefit the operation and experiment and the like, and provides a method of rearing single-head diamondback moths indoors. Fresh cabbage leaves are plugged in a feeding device to feed the single head diamondback moths, the feeding device comprises a cylinder-shape transparent feeding tube with both ends open, one end of the feeding tube is provided with a cabbage leaf growth block, the other end is provided with a sponge seal layer; a nutrition layer is arranged inside the cabbage leaf growth block, the top center of the cabbage leaf growth block is provided with a socket, and cabbage leaves are plugged in the socket. The cabbage leaves are kept in good freshness and tenderness and in good growth conditions by the plant nutrient solution. The adult life is extended through the rearing with fluctuating temperatures, and pupal weight is increased; the mortality rate of eggs, larva and pupa is reduced. Errors are reduced, the growth conditions of diamondback moths are easy to observe and record; the durability and operability are enhanced; and repeated use is possible. The device is low in manufacturing cost, secure, convenient and fast.

Description

technical field [0001] The invention belongs to the technical field of lepidopteran diamondback moth breeding, and in particular relates to an indoor breeding method for a single diamondback moth. Background technique [0002] Plutella xylostella, belonging to Lepidoptera, Plutellaidae, is distributed in cruciferous vegetable producing areas all over the country. It mainly damages cruciferous plants such as cabbage, purple cabbage, broccoli, stalks, mustard greens, cauliflower, cabbage, rapeseed, and radish. . Observing and mastering the development, survival, lifespan and reproduction of single-headed diamondback moth is an important basis for revealing the core life activities of diamondback moth in different ecological environments, and it is also the key to elucidating the environmental response mechanism of diamondback moth. To this end, it is necessary to create a test device and method of use that is relatively independent (free from interference by natural enemies, ...
