Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to a device for detecting the olfactory sensitivity of fig wasps in an air environment. Background Art

[0002] Banyan trees and fig wasps are one of the classic examples for studying coevolution. With a few exceptions, a single pollinating wasp usually only pollinates one type of banyan tree. Figs in the female flowering stage release volatile chemicals to attract pollinating fig wasps for pollination. In order to reproduce, pollinating fig wasps must accurately identify the chemical volatiles released by the host in the female flowering stage and be able to distinguish them from other odors in the environment. Different pollinating fig wasps can identify the unique chemical volatiles released by their own hosts. Therefore, smell plays an important role in maintaining the mutually beneficial symbiotic system between banyan trees and fig wasps.

The fig wasps themselves are very small and very fragile. Violent collection will cause damage to the fig wasps' bodies, which will lead to failure of the experiment; and letting the fig wasps fly back to the collection cage by themselves will prolong the experimental time, resulting in low experimental efficiency.

[0053] Then, the inner cavity of the cylindrical groove of the collecting block 70 has collected the fig wasps for the experiment and is in a sealed state. Then, the fixed circular plate 65 corresponding to the rear side of the experimental groove 21 is pulled to make the alignment disc 63 move to the rear side with the slide rod 62, and then the collecting component 7 is placed on the upper end of the corresponding positioning plate 31, so that the collecting block 70 is located between the two positioning plates 31, and the elastic force provided by the spring 1 64 is used to make the alignment disc 63 clamp the collecting block 70 between the two positioning plates 31. At the same time, the front end of the collecting block 70 and the magnetic block at the rear end of the corresponding stopper 33 attract each other, so that the connecting hole 2 34 corresponds to the truncated cone tube 78, and a collecting component 7 is placed on both the front and rear sides of the experimental groove 21;

[0054] Then, if Fig.11 As shown, the rotating plate 76 is rotated, and the support plate 75 is rotated through the connecting rod 74, so that the arc plate 77 is rotated, and the through hole 770 at the front end of the arc plate 77 is rotated to the same position as the inner cavity of the connecting ring 79, and then the baffle 35 corresponding to the rear side of the sealing block 20 is pulled, as shown in FIG. Figure 6 As shown, the second connection hole 34, the truncated cone tube 78 and the connection ring 79 are connected to each other, so that the fig wasps in the inner cavity of the cylindrical groove of the collection block 70 enter the sealed space formed by the second semicircular tube plate 254 and the first semicircular tube plate 251 in the inner cavity of the experimental groove 21 through the connection ring 79, the truncated cone tube 78 and the second connection hole 34 on the rear side, and the front and rear side baffles 35 are slid again to block the second connection holes 34 on the front and rear sides, so that the space of the fig wasp experiment is sealed to avoid interference from external odors, and then the actions of the fig wasps in the space formed by the second semicircular tube plate 254 and the first semicircular tube plate 251 are observed;

[0055] Through the multiple experimental slots 21 and the corresponding experimental components 25 and the placement component 3, multiple groups of different control experiments can be performed to detect the sensitivity of the fig wasp's sense of smell;

[0056] After the experiment is completed, the fig wasps in the experiment need to be collected, and the collecting component 7 is removed from the upper end of the second mounting block 30 on the rear side, and placed between the two positioning plates 31 on the upper end of the second mounting block 30 on the front side, so that the mounting disc 71 corresponds to the matching circular groove 52 on the front side, and then the motor 4 drives the screw 40 to rotate, so that the connecting block 57 on the surface of the screw 40 moves with the sliding plate 55, so that the micro-exhaust fan 56 moves to the corresponding matching circular groove 52 position, and the front baffle 35 is pulled open to open the second connecting hole 34, and then the micro-exhaust fan 56 is controlled to start exhausting, so that the fig wasps in the space formed by the semicircular tube plate 254 and the semicircular tube plate 1 251 fly to the front side under the action of suction, and then enter the inner cavity of the cylindrical groove of the collection block 70 through the second connecting hole 34, the truncated cone tube 78 and the connecting ring 79, and then, the rotating plate 76 is rotated to rotate the arc plate 77 to block the connecting ring 79 to prevent the fig wasps from flying out;

[0057] Then, the above operation is repeated, and different concentrations of odor sources are placed in the placement tubes 255 in the inner cavities of different experimental tanks 21, so as to make multiple groups of control experiments;

[0058] After the test is finished, the multiple cover plates 24 can be opened, and then the semicircular tube plate 2 254 and the connected connecting plate 253 in the inner cavity of the multiple experimental slots 21 can be rotated to clean the semicircular tube plate 254 and the semicircular tube plate 1 251 to avoid residual odor in the space formed by the semicircular tube plate 254 and the semicircular tube plate 1 251, which will affect the next experiment.
