Description
Technical field
The utility model relates to a kind of instrument that is used to observe meiofauna behaviors such as insect, spider, is specifically related to a kind of modified Y type olfactometer.
Background technology
The selection behavior of insect looks for food, keeps away the enemy insect, seek idol, play a significant role in the vital movement process such as lay eggs.The behavioural trend of describing and measure insect plays a significant role in the courses of work such as entomology teaching, determination of drug activity.But mostly as announcing in the Chinese utility model patent 201020239767.7, tradition " Y " type pipe is a kind of glass Y-pipe to " Y " type pipe of people's use at present, and odor source is positioned in two " support arms " (being referred to as " arm pipe " under this patent).Insect is positioned in another pipe of Y-piece (this patent is called " handle pipe " in the following text)." arm pipe " directly is communicated with " handle pipe ", and different flavors source gas flows into and stimulates from the arm pipe and is in the insect " handle pipe ", makes its behavior that makes a choice." the arm pipe " of such " Y " type pipe both sides and terminal " handle pipe " are straight tube all, the defective that exists flavor source, " arm pipe " both sides gas very easily to mix in three pipe intersections.Make rational selection behavior and have bigger interference effect for being in insect in " handle pipe " like this, be unfavorable for obtaining the science accurate data.
Summary of the invention
The technical problem that the utility model solves is the deficiency that overcomes prior art; A kind of modified Y type olfactometer that can effectively avoid the flavor source gas mixing of two side arms pipe is provided, is convenient to insect or meiofauna like this and distinguishes the gas in different flavors source and make rational selection behavior.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is following:
A kind of modified Y type olfactometer; Comprise two arm pipes that communicate of upper end and the handle pipe that is positioned at the lower end that is communicated with two arm pipes; Said arm pipe and connection place of handle pipe are provided with the separated flow deflector of flavor source air-flow that is used for two arm pipes, and said flow deflector extends in the handle pipe from the tube wall junction of two arm pipes.The utility model makes two kinds of odor sources of coming in from the arm pipe in the handle pipe, form different air-flow subregions through the setting of flow deflector, judges so that meiofaunas such as insect have clear and definite air-flow source, makes definite selection behavior.Solve the interior odor source mixing of handle pipe in the prior art and caused the difficult problem of making correct selection behavior of meiofauna.
Preferably, said flow deflector cross section is the Y-shaped in the opposite direction with Y type olfactometer, and said flow deflector comprises flow deflector handle and flow deflector bifurcated.From the odor source that the arm pipe is come, under the effect of air pump or other gas thrust units, gas molecule forms radiation on the flow deflector handle, then under the guide effect of flow deflector bifurcated, forms two bundle air-flows along the third handle tube wall.
Preferably, said handle pipe is caliber and increases the pyriform structure that afterwards reduces earlier, and said flow deflector bifurcated is positioned at the top of handle pipe maximum gauge position.The handle tubular construction of pyriform provides bigger activity space to meiofauna, and to promoting the definition that meiofauna behaviors such as insect are selected, the accuracy that improves conventional efficient and experiment plays positive role.And the flow deflector bifurcated is arranged at the top at handle pipe maximum gauge place, be to converge mixing from the air-flow that the flow deflector bifurcated flows out in maximum tube wall or its reflex owing to tube wall below position of the handle pipe of pyriform in order to prevent.Because above the maximum gauge of handle pipe, be the structure of dispersing, and below maximum gauge, then be the structure that converges.
Preferably, said flow deflector bifurcated is parallel with the tube wall of handle pipe opposite position.Certainly, do not need both strictnesses parallel, as long as approximate parallel.Like this from two arm pipes after the shunting action of flow deflector; Two bundle gases are parallel to the handle tube wall and flow; And can be because of the reflex of handle tube wall, leaving the flow deflector crotch just just mixes, but flows along the handle tube wall of pyriform; The maximum gauge place of arrival pyriform is stopped afterwards and is turned back that continuation is located along the insect place bottom the handle tube wall inflow handle pipe.So reduced possibility that the gas in different odor source mixes more, guaranteed that further meiofauna such as insect has clear and definite air-flow source judgement.
Preferably, the length of said flow deflector bifurcated is 1/3 ~ 1/2 of arm pipe diameter length.If the flow deflector bifurcated is oversize, then can limits insect etc. the activity space of meiofauna; And if the flow deflector bifurcated is too short, the distance that then causes air-flow to separate easily is big inadequately, and it is too near that two bundle air-flows leave, and is prone to cause air-flow to occur the phenomenon of mixing behind the flow deflector bifurcated.
Preferably, said two arm length of tube equate.Can make the judgement of oneself so that insect is experienced two kinds of different odor sources simultaneously like this.
Preferably, said two arm pipe clamp angular regions are 40-80 degree, make the air-flow molecule that flows in the arm pipe form stable reflected gas stream at flow deflector handle place.
Further, said two arm pipe clamp angular regions are 55-65 degree.
Said two arm pipe mouth of pipe places are provided with frosted mouth or buckle or the spiral mouth that is used to connect the external smells source.Be convenient to so directly connect, as required, can arm pipe end be made various structure with the external smells source.
The mouth of pipe place of said handle pipe is provided with frosted mouth or buckle or the spiral mouth that is used to connect outside animal release.Be convenient to the outside animal release of the terminal directly connection of handle pipe like this, multiple various structure type is to adapt to dissimilar animal releases.
Compared with prior art; The beneficial effect of the utility model technical scheme is: the utility model is through the setting of flow deflector; Make two kinds of odor sources of coming in the handle pipe, form different air-flow subregions from the arm pipe; Judge so that meiofaunas such as insect have clear and definite air-flow source, make definite selection behavior.In the prior art odor source mix and cause meiofauna difficulty make correct selection behavior and have substantive distinguishing features and progress.In addition; The flow deflector bifurcation design is become parallel or approximate parallel with the tube wall of handle pipe opposite position; Like this from two arm pipes after the shunting action of flow deflector, two bundle gases are parallel to the handle tube wall and flow, and can not mix because of the reflex of handle tube wall; Reduced possibility that the gas in different odor source mixes more, guaranteed that further meiofauna such as insect has clear and definite air-flow source judgement.
