Problems solved by technology

Often a large number of stinkbugs are urgently needed when pests occur, but the number of stinkbugs of the right age is insufficient to effectively play a role in pest control, and can only rely on chemical pesticides again; Reaching the level of economic harm, there is no need to release stinkbugs, which will increase the cost of labor and materials for breeding, which in turn will increase the price of stinkbugs, increase the cost of biological control, and reduce the enthusiasm of producers and users
[0005] Although in the prior art, the hatching time of stinkbug eggs is delayed by cold storage, they can only be stored for a short period of time. After 26 days, the hatching rate of the eggs is extremely low, and the hatching period is prolonged, and the eggs can be developed into insects that can be used to control pests. It takes 15 to 22 days for the state to form, resulting in the inability to supply natural enemy insect products in time
In addition, in some existing methods of storing gnats, some operations are too complicated and cumbersome. During the cold storage process, food and water must be added, and host plants must be replaced.
And when refrigerated, the stinkbug is placed in the cup, and it cannot be stored more at one time.
After refrigerating at 5°C and 10°C for 30 days with the above method, the survival rate of adults is only 33.65% and 45.21%. If the refrigerating period is extended, the survival rate will be further reduced, and the refrigerating time and survival rate will not reach the actual production. need, which increases the indirect cost; although the survival rate is higher at 15°C and 20°C, it is of little significance in actual production, because at this temperature, the stinkbug does not dormant, but still feeds, thereby increasing the artificial breeding the cost of

Embodiment 1

[0040] In the plastic box in step (3), place 200 stinkbug adults whose eclosion time is within 48 hours, first feed in an insect culture room at 26° C., feed sufficient tussah silkworm chrysalis and water; after 48 hours , moved 200 adult stinkbugs to a cold storage at 12°C for low temperature adaptation; after 48 hours, moved them to a cold storage at 5°C, and placed 50 adult stinkbugs in a plastic box, a total of four boxes. Among them, the length and width of the plastic box were 12 centimeters, and the height was 5.5 centimeters; finally, after 30 days, 45 days, 60 days and 90 days, respectively, a box of 50 adult stinkbugs was taken out to check their survival rate.

[0041] Such as figure 1 As shown, the average survival rates of the adult gnat bugs with different storage times obtained in Example 1 are respectively: 92.0%, 87.0%, 72.7%, and 62.0%.

Embodiment 2

[0043] In the plastic box in step (3), place 400 stinkbug adults whose eclosion time is within 24 hours, and the temperature is to feed in the insect culture room of 26 ℃, and feed sufficient tussah silkworm chrysalis and water; after 48 hours, place 400 adult gnats were moved to a cold storage at 12°C for low temperature adaptation; after 48 hours, they were moved to a cold storage at 5°C, and each 100 adult stinkbugs were stored in a plastic box, a total of four boxes. Among them, the length and width of the plastic box were 12 centimeters, and the height was 5.5 centimeters; finally, after 30 days, 45 days, 60 days and 90 days, respectively, a box of 100 adult stinkbugs was taken out to check their survival rate.

[0044] Such as figure 2 As shown, the average survival rates of the adult gnats of different storage times obtained in Example 2 are respectively: 98.7%, 97.0%, 91.0%, and 71.7%.

Embodiment 3

[0046]In the plastic box in step (3), place 1000 stinkbug adults whose eclosion time is within 48 hours, and the temperature is to feed in the insect culture room of 26 ℃, and feed sufficient tussah silkworm chrysalis and water; after 48 hours, put 1000 adult gnat stinkbugs were moved to a cold storage at 12°C for low temperature adaptation; after 48 hours, they were moved to a cold storage at 5°C, and every 250 adult stink bugs were stored in a plastic box, a total of four boxes. Among them, the length of the plastic box is 32 centimeters, the width is 25 centimeters, and the height is 9 centimeters; finally, after 30 days, 45 days, 60 days and 90 days, take out a box of 250 adult stink bugs respectively, and check their survival rate .

[0047] Such as image 3 As shown, the average survival rates of adult gnat bugs with different cold storage times obtained in Example 3 are 96.7%, 83.7%, 66.7%, and 59.0%, respectively.

[0048] Wherein, the survival rate of adult gnats in...

Abstract

The invention discloses a method for cold storage of Arma chinensis adults, which comprises the following steps: considering the low-temperature resistance of Arma chinensis adults, carrying out short-term low-temperature adaptation on Arma chinensis adults with a certain eclosion time in a refrigeration house, and then putting Arma chinensis adults into the refrigeration house with lower temperature for medium-term and long-term storage; when Arma chinensis adults need to be used, moving the Arma chinensis adults out of the refrigeration house and gradually heating to the normal temperature.Therefore, Arma chinensis adults can be stored for a medium and long term and can be used for preventing and controlling pests at any time.

Description

technical field [0001] The invention relates to the technical field of artificial breeding of insects, in particular to a method for refrigerated preservation of adult gnat bugs. Background technique [0002] The stinkbug belongs to the Hemiptera Pentatomidae, and it is an excellent predatory natural enemy insect, which can prey on various pests of Lepidoptera, Coleoptera, and Hemiptera, and has important applications in the biological control of agricultural and forestry pests prospect. [0003] In China, stink bugs have been widely used in the biological control of Lepidoptera pests on tobacco, and also in northern garden trees and vegetable crops. As the country pays more attention to environmental protection, it will soon be widely used in the pest control of plants such as tea, fruit trees, garden green plants, and protected vegetables. At present, there are several breeding bases and factories of stinkbugs in the whole country, and the total annual production of stin...
