Abstract

The invention relates to a Tetranychina harti feeder, which belongs to the technical field of entomology experiment. The feeder consists of an upper feeding chamber and a lower water pool. Safflower oxalis leaf isolated leaf with petiole is vertically planted into the feeder. The blade in which the mite is cultivated is hung in the feeding chamber. The petiole enters under the water level of the water pool through a petiole inserting pipe at the bottom of the feeding chamber. When the Tetranychina harti is fed by the feeder, the blade part of the safflower oxalis leaf is free from the preserving liquid, therefore the blade is difficult to yellow and mildew, the blade surface is dry, and the mite can freely move on the blade, and has natural living state. The feeding chamber is manufactured by a disposable plastic cup, a gauge and the like, and has the advantages of sealing property, permeability and light transmission; and the microenvironment in which the mite is cultivated is consistent with the set feeding condition. Each component of the feeder is easy to disassemble and assemble, therefore the microscopic observation and replacement of the blade are convenient.

Description

Tetranychina harti feeder

Technical field

The present invention relates to a kind of device of raising creeping oxalis such as tetranychid, belong to insect (acarian) and learn the experimental technique field.

Background technology

Creeping oxalis such as tetranychid are a kind of tetranychids of fully not studied as yet.This mite can do the wild creeping oxalis of Chinese medicine except that getting food, and also serious harm is used for the window-box oxalis that scape is made in gardens.

In the research of tetranychid, often need under impose a condition, carry out individual feeding or quantitatively raise, and in feeding process, carry out the timing observation this mite.To mainly getting the tetranychid at food host blade position, can raise (excised leaf method) with the blade under adopting from host plant, also can raise on the blade on the plant that lives (live body blade method), need to adopt certain method or utensil to make blade keep fresh under the previous case and prevent the mite escape, also need anti-the escape under the latter event.In order to guarantee the accuracy of result of study, raising method that is adopted or utensil should be able to effectively be controlled the unusual death of tetranychid and missing, and the condition (temperature, humidity etc.) of animation nature, the residing microenvironment of mite and the setting of blade good refreshing effect, mite is consistent, observing operation simultaneously will make things convenient for.But at present in existing tetranychid raising method or utensil, also do not have anyly can satisfy above-mentioned requirements simultaneously and adapt to creeping oxalis such as the characteristics of tetranychid (individuality is bigger, and foot is longer, and the host plant blade is little).

That has reported makes foodstuff with excised leaf and raises exemplary process or the utensil of tetranychid water pond method, cell method, He Shi feeder, field Cheng Shi feeder etc. are arranged, their common ground is: excised leaf (or leaf dish) is divided in wet basis (water surface or moistening absorbent material such as blotting paper, cotton, sponge etc.) gone up with fresh-keeping, wait and prevent the tetranychid escape with the water surface, wet suction paper slip, cell wall around the blade.Therefore can be referred to as the wet basis blade method that exsomatizes.These class methods have the mite of observation advantage eaily, but a lot of defectives are arranged also: (1) blade is too high because of being close to the wet basis surface moisture, the foot that makes tetranychid is stained with dirts such as ight soil easily and activity is obstructed, and make blade turn to be yellow easily, mouldy and influence its life-span and nutrition; (2) tetranychid can only be in the blade face activity that makes progress, and position is often unnatural; (3) because of the wet basis water evaporates, the blade surface temperature is starkly lower than environmental temperature (temperature that promptly sets); When (4) adopting the water pond method, many tetranychids can be strayed into the wet basis material around the blade and cause death or missing, particularly the kind of body thigh length (as creeping oxalis such as tetranychid).The accuracy of these defective effect test datas, even test is fallen flat.On the plant that lives, carry out individual feeding of tetranychid or quantitatively raising, use bagging method (entangling the branch at mite place with plastic sack) or folder cage method (pressing from both sides special shrouding for a short time on the blade) usually.The major advantage of these class methods is generally to need not to consider the fresh-keeping problem of blade in the feeding process, and major defect is in feeding process mite to be carried out the timing microscopy to observe very inconveniently, and is not suitable for creeping oxalis (because the creeping oxalis plant is very weak, and blade is little).

Summary of the invention

Technical problem the purpose of this invention is to provide a kind of Tetranychina harti feeder, and this feeder can satisfy following requirement simultaneously: can effectively control the unusual death rate of creeping oxalis such as tetranychid and missing in the feeding process; The blade fresh keeping time is long; The animation of mite is more natural; The residing microenvironment of mite and the basically identical that imposes a condition; The observation of mite is more convenient.Adopt this feeder can improve the accuracy of creeping oxalis such as tetranychid data greatly.

Technical scheme in order to achieve the above object and requirement, the technical solution adopted in the present invention is:

A kind of Tetranychina harti feeder is made up of the receptacle on top and the pond of bottom, and the receptacle frame is on the pond, and both were both relatively independent, communicates with the inserting handle pipe that is fixed in the receptacle bottom again.Receptacle is fastened mutually by end cup and cover and forms, and end cup is the high part of the about 60mm in a kind of disposable plastic water tumbler bottom, and its bottom center is equipped with a hole, is used for inserting and fixing inserting handle pipe; Cover is formed by decorative cover, cover collet chuck tight feeder cloth lid, wherein decorative cover is the high part of 20mm from the intercepting of disposable plastic water tumbler top, the cover tube is the major part on another plastics water tumbler top, and the gauze lid is the square gauze piece about the big 40mm of side ratio water tumbler back cut diameter.Long one section of 35mm in the plastic suction pipe that described inserting handle pipe is diameter 5mm, the top is wrapped up in gauze.Described pond is glass beaker or other transparent heavy wall hydrostatic columns, and its bore is less than bore on the disposable plastic water tumbler but greater than footpath at the bottom of the plastic cup.

The using method of feeder is: the cover that takes off receptacle, the petiole broken ends of fractured bone of window-box oxalis leaf is inserted via inserting handle pipe upper end gauze fibre gap, by the laggard underwater of going into the pond of inserting handle pipe, blade-section uprightly is suspended in the receptacle, can on blade, connect mite as required, then cover be resetted; When needing to observe the mite on the blade in the feeding process, can take out leaf after taking off cover, check and leaf is returned after finishing slottingly, again cover be resetted.

Beneficial effect

The unusual death rate of creeping oxalis such as tetranychid is lower than various stripped wet basis blade methods; The missing rate of mite is significantly less than the water pond method; The microenvironment of mite life is much smaller with the various stripped wet basis blade methods of diversity ratio that impose a condition, and is also little than folder cage method; The animation of mite is than more natural under existing most methods; The observation of mite is more convenient than live body blade method; The fresh keeping time of blade is more much longer than stripped wet basis blade method; The replacing of blade is more more convenient than various stripped wet basis blade methods; It is easy, simple for production that the while feeder is drawn materials, and cleaning and collection are also more convenient.

When using the present invention to raise creeping oxalis such as tetranychid, the window-box oxalis leaf stands in the feeder, and its blade-section uprightly is suspended in the receptacle naturally, away from the liquid of fresh-keeping usefulness, inhibited from yellowing and mouldy, the blade face is dry and comfortable, mite can be free movable on blade, and its animation is more natural.Petiole then enters the pond by the inserting handle pipe, by broken ends of fractured bone suction, blade is played good preservation.Receptacle is base closed (being formed by cover and tight fastening of end cup), can prevent fall into the water death or escape missing of mite, its manufacturing materials is disposable plastic water tumbler and hospital gauze etc., therefore have certain ventilative, light transmission again, make the residing microenvironment of mite more consistent with the condition of setting.Serve as with glass beaker or other transparent heavy wall hydrostatic columns in the pond, has both had light transmission, makes the feeder center of gravity more stable again.Each parts of feeder can be dismantled and assemble at an easy rate, make the microscopy observation of blade and change more convenient.
