As shown in fig. 1-4: a device for distinguishing insects migrating to fly and flying freely comprises a flying cage (15), an insect collecting box (11), a light induction area and an experiment recording element. The take-off cage (15) and the insect collecting box (11) are both made of PVC transparent materials. The take-off cage (15) is composed of a cylindrical part and a conical part, the upper end of the conical part is provided with a connecting port which is connected with the insect collecting box (11), and the connecting port is provided with a one-way funnel baffle (22) which can prevent insects entering the insect collecting box (11) from reversely passing through. The diameter of the bottom of the take-off cage (15) is 50 cm, the height of the cylindrical part is 120 cm, the height of the conical part is 30 cm, and the diameter of the connecting port is 20 cm. The bottom of the take-off cage (15) is provided with a water holding layer (29), a take-off platform (28) and a illuminometer platform (20) and is provided with 10 food containers (21). An illuminance sensor (18) is disposed on the illuminance meter platform (20). The illuminance sensor (18) is connected with an illuminometer display (19) which is arranged outside the takeoff cage (15) and used for recording the illuminance intensity in real time. A take-off platform cover plate (26) is arranged above the take-off platform (28), and extends out of the take-off cage (15) through a push-pull opening (27) on the take-off cage (15) for controlling the take-off platform (28) to be opened and closed. The side wall of the take-off cage (15) is provided with a take-off cage movable door (25). A black dividing line (23) is drawn at the position of the side wall of the take-off cage (15) 100 cm away from the bottom, and the take-off cage (15) is divided into an upper part and a lower part and is used for distinguishing insects which fly in a migration manner and take off in a free diffusion manner. The inner wall of the take-off cage (15) at the part below the black separation line (23) is attached with a glue coating (24) for adhering insects which freely spread and take off. The bottom of the insect collecting box (11) is provided with a food containing box (13), and the side wall is provided with a collecting area movable door (12). A support (17) is arranged outside the take-off cage (15), an infrared counter (14) and an infrared camera (16) are mounted on the support (17), the infrared camera (16) corresponds to a free diffusion area below a black separation line (23), and the infrared counter (14) corresponds to a migration area above the black separation line (23). The light induction zone is provided with a lamp holder (1), 1W infrared lamp (7) is installed on the lamp holder (1), 14 WLED lamps (2) of 40WLED, 2 LED lamps (3) of 25W, 8WLED lamps (4) of 2 WLED lamps, 25W incandescent lamps (5) of 1, 18W incandescent lamps (6) of 1, each bulb is connected with a light control device (10) through an electric wire (8), the sequential closing of each bulb can be controlled through the light control device (10) as required to control the illumination intensity, and the on-off state of the bulb can be displayed on a light control device display (9) in real time.
The change in illumination intensity at natural sunset is shown in fig. 5. To simulate this illumination change, the bulb was controlled by the light control device (10) to turn off from high to low wattage, with 14 40WLED lamps (2), 2 25W LED lamps (3), 28 WLED lamps (4) turning off 2 every 3 minutes, followed by 2 minutes of turning off 1 25W incandescent lamp (5), and 1 minute later turning off 1 18W incandescent lamp (6).
When migrating to fly and taking off, the rice leaf roller flies in a vertical spiral rising manner or flies in a straight rising manner at a large elevation angle, and when taking off in a free diffusion manner, the rice leaf roller flies freely and dispersedly in a non-directional and invisible manner. The black separation line (23) is arranged at the position, 100 cm away from the bottom, of the cylindrical side wall of the take-off cage (15), and the vertical spiral rising or straight rising with a large elevation angle for migrating and taking-off can reach the height, but the rice leaf rollers taking off in a free diffusion mode cannot reach the height. For the rice leaf rollers which ascend linearly at a large elevation angle and fly in a migrating manner, if the black separation line (23) is too high, the black separation line can touch the glue coating layer (24) below the black separation line (23) and be stuck, and the black separation line cannot be distinguished from the rice leaf rollers which fly in a free diffusion manner. For the rice leaf rollers which take off in a free diffusion mode, if the black separation line (23) is too low and is easy to reach, the black separation line cannot be distinguished from the rice leaf rollers which take off in a migration mode. After a plurality of tests of the inventor, the black separation line (23) is arranged at the position 100 cm away from the bottom of the cylindrical side wall of the takeoff cage (15) in the best mode. Therefore, the black separation line (23) can effectively distinguish cnaphalocrocis medinalis which takes off in migration flight and takes off in free diffusion. In addition, a reserved area at the upper end of the black separation line (23) is convenient for the infrared counter (14) to count the cnaphalocrocis medinalis which flies and takes off.
The device is used for simulating the influence of sunset illumination change on the takeoff behavior of the rice leaf rollers: firstly, water and food are respectively added into a water containing layer (29) and a food container (21) through a take-off cage movable door (25), rice leaf rollers are placed into a take-off platform (28), and a take-off platform cover plate (26) is covered. All bulbs in the light induction area are turned on, and the turn-off sequence and time of the bulbs are set through the light control equipment (10) so as to simulate the sunset lighting conditions. Food is added into the food containing box (13) through the collecting area movable door (22). And opening the infrared counter (14), the infrared camera (16) and the light control equipment (10), and pulling off the take-off platform cover plate (26) to start the experiment. The infrared lamp (7) keeps a long bright state in the experimental process so as to facilitate the observation of experimental records.
After the experiment is finished, the cnaphalocrocis medinalis migratorius taking off is gathered in the insect collecting box (11), the cnaphalocrocis medinalis free-diffusion taking off is mostly adhered to the gluing layer (24), the cnaphalocrocis medinalis migratorius taking off and the cnaphalocrocis medinalis free-diffusion taking off can be respectively collected through the collecting region movable door (12) and the taking-off cage movable door (25), and collected test insects can be used for researches such as gene comparison.
The experimental data were statistically analyzed, and the proportional relationship of the cnaphalocrocis medinalis guenee in the emigration takeoff with time is shown in fig. 6. Comparing fig. 5 and fig. 6, it can be seen that the change of the sunset illumination from strong to weak is the high-incidence period of the emigration of the cnaphalocrocis medinalis, and the experimental data obtained by the device indoors is basically consistent with the experimental data in the field, but the difference still exists.
The proportion of the cnaphalocrocis medinalis which flies off in a migration manner and is observed in the field is suddenly increased, then changes from high to low, and is concentrated in two time periods. The proportion of the cnaphalocrocis medinalis which flies and takes off in a migration manner measured by the device is changed from low to high and then from high to low with a relatively mild trend. The difference of the proportion change trend of the cnaphalocrocis medinalis which flies and takes off in the field measured by the device is large. When the experiment is carried out in the field, the experiment condition is uncontrollable, and the migrating flying and taking off of the insects are possibly influenced by the change of other environmental factors such as temperature, humidity and the like except sunset illumination. When the device is used for experiments, only the illumination change is adjusted, other experiment factors are effectively controlled, and the experiment result can reflect the influence of a single illumination factor. The experiment that the illumination change influences the takeoff behavior of the insects is carried out by using the device, and the measured experimental data more accurately reflects the effect of the illumination change, so that a more reliable guarantee is provided for pest control or subsequent further research on other biological biochemistry of the migratory flying insects and even on the gene level. In addition, when the illumination is taken as a main research factor, accurate research and analysis on the intrinsic physiological mechanism of the single factor influencing the migratory insects are further facilitated.
The above embodiments are only used for illustrating the technical ideas and features of the present invention, and the scope of the present invention should not be limited thereby, and any modifications made based on the technical ideas and features of the present invention are within the scope of the present invention. The technology not related to the invention can be realized by the prior art.
