[0028] Application test example 1
[0029] use figure 1 Device, random 4 light sources are used as a group for treatment, each treatment with 50 oriental migratory locust adults, dark treatment for 15 minutes before treatment, 30 minutes for each treatment, repeat 3 times, dark conditions as a control, screening out the better phototaxis Processing is regrouped for processing. Test the trapping effect of 10 kinds of light sources on the adult migratory locust in East Asia, the results are as follows figure 2 As shown, the attracting rate of the 10 kinds of light sources to the adult migratory locust in order from high to low is: 460±10 nm>505±10 nm>435±10 nm>375±10 nm, 365±10 nm>incandescent lamp>575 ±10 nm, 600±10 nm, 645±10 nm, 690±10 nm, and 460±10 nm wavelength light source attracting rate was significantly higher than 505±10 nm treatment and 435±10 nm treatment. Therefore, a light source with a wavelength of 460±10 nm has the best trapping effect on adult locusts.
Example
[0030] Application test example 2
[0031] use figure 1 The device is equipped with 5 light sources at random as a group for treatment, each with 50 1st instar nymphs of Oriental migratory locust, dark treatment for 15 min before treatment, 30 min for each treatment, repeated 3 times, dark conditions as a control, screening out trends Better treatments are recombined for treatment. Test the trapping effect of 10 light sources on the 1st instar nymphs of the migratory locust, the results are as follows image 3 As shown, the attracting rate of 10 kinds of light sources to the first instar nymphs of the migratory locust in descending order is: 505±10 nm, 460±10 nm, 375±10 nm> incandescent lamp, 435±10 nm, 365±10 nm >575±10 nm>600±10 nm, 645±10 nm, 690±10 nm, there is no significant difference in the phototaxis of first instar nymphs to 505±10 nm, 460±10 nm and 375±10 nm wavelength light sources. Therefore, light sources with wavelengths of 505±10 nm, 460±10 nm and 375±10 nm have t...
Example
[0032] Application test example 3
[0033] use figure 1 The device is equipped with 5 light sources randomly as a group for treatment, each with 50 3rd instar nymphs of Oriental migratory locust, dark treatment for 15 min before treatment, 30 min for each treatment, repeated 3 times, the dark condition is the control, and the trend is selected. Better treatments are recombined for treatment. Test the trapping effect of 10 light sources on the 3rd instar nymphs of the migratory locust, the results are as follows image 3 As shown, the attracting rate of 10 kinds of light sources to the 3rd instar nymphs of the migratory locust in descending order is 375±10 nm>505±10 nm>365±10 nm>435±10 nm>460±10 nm, incandescent lamp> 575±10 nm, 600±10 nm, 645±10 nm, 690±10 nm, and wavelength 375±10 nm light source to attract 3rd instar locust nymphs were significantly higher than 505±10 nm and 435±10 nm. Therefore, the light source with a wavelength of 375±10 nm has the best trapping effect on t...
