Embodiment
For making object of the present invention, technical scheme and advantage clearly understand, below by specific embodiment and relevant drawings, the present invention will be described in further detail.
As shown in Figure 1, a kind of easy device measuring tiny insect and liquid adhesive power, comprise inverted T-shaped support 1, be hinged in the middle part of described support 1 upper end and the lever 2 be horizontally set with, lever 2 length is about 12cm, and described lever 2 two ends are provided with pointer 9, and lever 2 two ends are also have length-adjustable cotton thread 4, cotton thread 4 lower end system is provided with coil 5, the coil 5 on the right side of being positioned at is linked with to hang the spun gold 6 of insect 7; Also comprise and be located at index dial on the left of lever 2 left end pointer 10 and be located at below spun gold 6 for filling the vessel 11 of liquid, in vessel 11 survey liquid can variation, as distilled water, vegetable oil, acetone etc., described index dial 10 Centromedian zero graduation line is concordant with lever 2.
In the present embodiment, also comprise the isometric segment spun gold 8 of multistage used as counterweight, because the adhesion of tiny insect and liquid belongs to relatively little power, using segment spun gold 8 as counterweight, be hung in the coil on the left of lever with microforceps after doubling, can accurately measure small weight by adding segment spun gold one by one, ensureing the accuracy that adhesion is measured.
In the present embodiment, described lever 2 adopts plastic suction pipe, and described pointer 9 adopts No. 3 insect needles and inserts in lever 2 two ends and use plasticine cementation.
In the present embodiment, in the middle part of described lever 2, offer slotted eye, and wear No. 5 insect needles 3 and be installed on pedestal upper end; Scale mark on described index dial 10 forms the arcuate structure concentric with slotted eye.
In the present embodiment, described cotton thread 4 upper end lies on the bundle hole of lever 2 end.
Meanwhile, the present invention also provides a kind of its measuring method measuring tiny insect and liquid adhesive power, adopts a kind of easy device measuring tiny insect and liquid adhesive power as above, and carries out according to the following steps: (1) uses CO
2by smoked for insect 7 dizzy; (2) with elargol, spun gold 6 lower end is adhered on insect 7 chest backboard, and the upper end of spun gold is hung on the coil of right side, and stamp brief summary, in order to avoid come off; (3) turn left on lateral coil 5 and hang up segment spun gold 8 one by one, until the zero graduation line place of left side pointed index dial 10; (4) measure the quality m1 of all segment spun golds on the coil of left side, and the segment spun gold after measuring is hung back on the coil of left side again; (5) left end cotton thread length is regulated to make insect 7 move on the liquid level of vessel; (5) treat that insect is still on liquid level, continue to turn left lateral coil interpolation segment spun gold until by insect 7 from liquid level pull-up; (6) the quality m2 of all segment spun golds on the coil of left side is measured; (7) take off insect, measurement completes.The unit of m1 and m2 is
, according to (m2-m1) × 9.8 can calculate leafhopper and water adhesion (unit:
).
In the present embodiment, for ensureing that syndeton is simple and the reliability connected, in step (2), under Stereo microscope, first spun gold bottom can be pinched out small circle with microforceps, so that dip elargol, spun gold 6 lower end touching insect chest backboard also stops 10s, ensures the steadiness that spun gold is connected with insect.
In the present embodiment, the liquid in described vessel is distilled water, and adhesion that the tea lesser leafhopper adult of 3mm and nymph carry out above-mentioned steps is respectively measured to adopt body to be about.
The present embodiment measurement result shows, and the average adhesion of tea lesser leafhopper nymph and water reaches 108.58 ± 3.54
, be about 28 times of self gravitation, the adhesion of adult and water is then only 37.24 ± 1.16
, be about 7 times of self gravitation, therefore the adhesion of nymph and water is significantly greater than the adhesion of adult and water.
Above-listed preferred embodiment; the object, technical solutions and advantages of the present invention are further described; be understood that; the foregoing is only preferred embodiment of the present invention; not in order to limit the present invention; within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
