Description

TECHNICAL FIELD

[0001] The utility model relates to parasitic wasp feeding technical field, concretely relates to a kind of parasitic wasp feeding device of continuous feeding nutrient solution. BACKGROUND

[0002] With the green development concept is accepted by people, green prevention and control technology has important role in realizing agricultural green production, promoting ecological balance and the technology is increasingly valued by people, especially biological control. But in the practical application of biological control, the lack of low-cost propagation technology of natural enemy insects is the bottleneck of limiting its mass production of natural enemy and regional release. Therefore, how to breed natural enemy insects at low cost is a research hotspot, and currently people mainly focus on the temperature, humidity and suitable host of natural enemy insects feeding. When the temperature, humidity and host of feeding are determined, additional liquid nutrient substance is also a method to reduce feeding cost, because the additional exogenous nutrient substance can prolong the life of natural enemy insects and improve the egg-laying amount, so as to achieve the purpose of low-cost mass production. Exogenous nutrient substance is mainly supplied to parasitic wasp, because parasitic wasp can affect the clutch size and reserve energy by absorbing and distributing different nutrient substances, finally affecting the reproductive capacity. Parasitic wasp mainly prolongs the life, improves the egg-laying amount and parasitic capacity by feeding nectar and honeydew in the field, and needs to provide sugar as exogenous substance artificially when feeding in laboratory. Sugar is an important source of insect growth and development, reproduction and energy, and different sugars have obvious differences in the influence on parasitic wasp due to different structures and effects. Therefore, it is extremely necessary to provide sugar and other exogenous substances in the mass production of parasitic wasp.

[0003] When artificial feeding parasitic wasp, transparent plastic box, glass jar or other container with good air permeability is usually used as feeding box, and sugar and other exogenous substances are supplemented in the feeding box as food. At present, the ways to supplement nutrient solution are as follows: one is to open a hole in the top of the feeding box and paste gauze, and then put cotton soaked with nutrient solution on the gauze for parasitic wasp to feed; the other is to put cotton soaked with nutrient solution on the wall of the feeding box for parasitic wasp to feed. Since nutrient solution has viscosity, when parasitic wasp or host contacts the cotton, nutrient solution may adhere to the foot or wing, thereby affecting the activity of parasitic wasp or host, and even causing the death of parasitic wasp due to crawling. At the same time, when parasitic wasp or host carries nutrient solution and contacts the cotton for many times, it will cause pollution of nutrient substance, and when parasitic wasp feeds the unclean nutrient solution again, it will finally affect its survival rate and life. The two ways to provide nutrient solution described in the patent have the above-mentioned disadvantages. Therefore, the utility model discloses a kind of parasitic wasp feeding device of continuous feeding nutrient solution to solve the above-mentioned problems existing in providing nutrient solution. SUMMARY

[0004] The utility model aims at providing a parasitic wasp feeding device of continuous feeding nutrition liquid, in order to continuously supply nutrition liquid to feed parasitic wasp.

[0005] In order to solve the above technical problem, the utility model provides the following technical scheme: a parasitic wasp feeding device of continuous feeding nutrition liquid, including feeding box and feeding assembly, the feeding box includes box body and box cover,

[0006] The feeding assembly includes containing box, containing box sets up in the box body, is equipped with vertical liquid pipe on containing box, is equipped with a plurality of feeding holes on the liquid pipe, and the feeding hole is communicated with the inside of liquid pipe, and the top of liquid pipe passes through the box cover and is located outside the feeding box, the cotton ball is placed in the liquid pipe, and the cotton ball is located at the same height with the feeding hole, and the bottom of cotton ball is connected with cotton rope, and cotton rope extends to containing box.

[0007] The utility model works: when needing to provide nutrition liquid, injects nutrition liquid in containing box, because the cotton ball is placed in the liquid pipe, and the cotton ball is located at the feeding hole, and the bottom of cotton ball is connected with cotton rope, and cotton rope extends to containing box, therefore, after injecting nutrition liquid in containing box, nutrition liquid will flow to the cotton ball along the cotton rope under the capillary action, and the cotton ball is located at the same height with the feeding hole in the liquid pipe, when parasitic wasp feeds nutrition liquid, and can feed the nutrition liquid on the cotton ball by contacting the feeding hole with the mouth organ. When the nutrition liquid reduces, can inject in containing box through the liquid pipe by using the syringe, in addition, when the cotton ball needs to be replaced, the cotton ball and cotton rope are taken out from the top of liquid pipe by using the tweezers, and then the new cotton ball and cotton rope are put into the liquid pipe.

[0008] The utility model has the advantages of:

[0009] 1, this scheme passes through the capillary action of cotton rope and cotton ball, and the nutrition liquid can continuously flow from containing box to feeding hole, ensures that parasitic wasp obtains fresh nutrition liquid at any time, reaches the purpose of continuous feeding, the design only the mouth organ of parasitic wasp can be inserted into the feeding hole and feeds, and other parts will not stick nutrition liquid, ensures that the inside of feeding box is clean and sanitary.

[0010] 2, when needing to supplement nutrition liquid, injects nutrition liquid to containing box from the top of liquid pipe by using the syringe, avoids the inconvenience and parasitic wasp escape situation caused by the frequent opening and closing of box cover.

[0011] 3, when the cotton ball needs to be replaced, only needs to take out the cotton ball and cotton rope from the top of liquid pipe by using the tweezers, and then inserts the new cotton ball and cotton rope, and the operation is simple and fast.

[0012] Further, the feeding hole is 3, and the 3 feeding holes are vertically and spaced apart. The purpose is to allow multiple parasitic wasps to feed nutrition liquid simultaneously, and also to avoid the body part of the parasitic wasp contacting another feeding hole when feeding.

[0013] Further, the top end of the liquid tube is flared. The purpose is to facilitate the installation and removal of cotton and cotton rope.

[0014] Further, the top of the containing box is provided with a threaded hole, and the bottom end of the liquid tube is screwed into the threaded hole. The purpose is to facilitate the removal of the liquid tube from the containing box, which is beneficial to the repeated use of the liquid tube after cleaning.

[0015] Further, the containing box comprises a box body and a closure cover, and the closure cover is detachably connected to the box body. The threaded hole is arranged on the closure cover. The purpose is to facilitate the cleaning of the inside of the containing box after the closure cover and the box body are separated. BRIEF DESCRIPTION OF DRAWINGS
