Technical field
Utility model belongs to the determinator technical field, is specifically related to a kind of planthopper resistance to the action of a drug determinator.
Background technology
Planthopper (brown paddy plant hopper, white backed planthopper, small brown rice planthopper) is the primary pest on China's Rice Production, and generating capacity is large, and it is serious to cause harm, and the safety in production of China paddy rice in serious threat.Prevent and treat at present the main applied chemistry agricultural chemicals of method of planthopper.It is the major reason that causes planthopper to develop immunity to drugs that long-term large tracts of land is used single pesticide species and Irrational Use of Drugs.A key prerequisite of planthopper resistance management is the estimation to early stage resistance level, instructs the correct use of pesticide with this.Domesticly mainly contain drop method, medicine (bottle) embrane method, spray-on process, soak seedling method and rice stem infusion process etc. for the resistance monitoring method of planthopper to pesticide, the external Detection of insecticide resistance that also has filter paper method, agar plate method, dull and stereotyped microdetermination analytic approach and enzymoimmunoassay etc. to measure planthopper, wherein the easiest method is spray-on process, soaks seedling method and rice stem infusion process, equipment therefor is test tube or cultivates cup in these three kinds of methods, rice seedling is easily withered, is not suitable for the slow pesticide of drug action the resistance level of planthopper is measured.
The utility model patent can be used for measuring all pesticides to the Detection of insecticide resistance of planthopper, has rice seedling and is difficult for the characteristics such as withered, that the insect natural mortality rate is low, and measurement result is accurate.
Summary of the invention
In order to overcome the above problems, the utility model provides a kind of planthopper resistance to the action of a drug determinator, utilize this device can all pesticides of Accurate Determining to the Detection of insecticide resistance of planthopper, have simultaneously rice seedling and be difficult for the characteristics such as withered, that the insect natural mortality rate is low, and measurement result is accurate.
The utility model provides a kind of planthopper resistance to the action of a drug determinator, it is characterized in that, this device comprises: tubular the first cavity (11) that is surrounded by sidewall (10), comprise respectively the first opening (12) and the second opening (13) at these the first cavity two ends, wherein, also comprise tapered second cavity (20) in the first cavity, the longitudinal axis of the longitudinal axis of this cone-shaped cavity and tubular the first cavity is overlapping; Comprise the opening (21) that allows the cauline leaf of rice seedlings pass and be positioned at the first cavity at taper one end of cone-shaped cavity, simultaneously, the opening (21) of taper one end is positioned at the below of second opening (13) of cylindrical cavity, wherein, between cone-shaped cavity and cylindrical cavity, be formed for holding the 3rd cavity (30) of rice root and carrier.
In some preferred modes, the bottom of the second tapered cavity communicates with tubular the first cavity.
In some preferred modes, comprise the lid that seals this opening at the end opening (13) of described cylindrical cavity, in order to form the cavity of a sealing, allow the root of rice seedlings be arranged in the 3rd cavity.The first opening (12) at described cylindrical cavity comprises covering the gauze of this first opening, in order to allow the air of cylindrical cavity keep unimpeded with extraneous.
In some preferred modes, in described the 3rd cavity, comprise the carrier that can keep moisture.Utilize this carrier to provide nutrition or moisture for paddy growth, it is dead to guarantee that paddy rice is difficult for.Carrier can be any flexible material that can absorb water, such as cotton, filter paper, nonwoven fabrics etc.
In some preferred modes, it is 1.5-2 centimetre at the described diameter that is positioned at the opening of tapering point.
In some preferred modes, the diameter of tubular cavity is 5 centimetres, and is long for 15-30 centimetre.
In some preferred modes, the height of cone-shaped cavity is 3 centimetres, or the long 1/5-1/10 of tubular cavity.
Beneficial effect
The utility model can be used for measuring all pesticides to the Detection of insecticide resistance of planthopper, has rice seedling and is difficult for the characteristics such as withered, that the insect natural mortality rate is low, and measurement result is accurate.
