The experimental effects are shown in table 1: TABLE 1 statistics of trapping effect of different wavelength light sources (first/late)
The observation of the figure shows that through three comparisons of a combined light source, a single-wave light source and a commercial light source adopted in the field, experiments show that the combined light source has the highest trapping amount of the target insect prodenia litura, the trapping amount of the combined light source is improved by 34.25% compared with the commercial light source, the trapping amount of the combined light source is also obviously higher than that of the other two light sources, the total insect amount is obviously lower than that of the commercial light source, and the results show that the combined light source can improve the trapping amount of the prodenia litura, and meanwhile, the trapping amount of the combined light source of the non-target insects, particularly natural enemy insects is also obviously lower than that of the commercial light source.
TABLE 2 trapping amount of different wavelength light sources for non-target insects (first/late)
As can be seen from the figure, statistical analysis of natural enemy insects shows that the insects of the families Trapae and ladybirda in Coleoptera are mainly included. The results show that the natural enemy trapping amount of the combined light source is reduced by 42.79 percent compared with the commercial light source. The test results show that the combined light source has stronger specificity to prodenia litura and has small killing effect on non-target insects (natural enemy insects).
In this embodiment, the trap 1 includes a housing 11 having a cavity therein and being open at one side, a trapping light source 12 and a wind power unit 13, the trapping light source 12 is disposed in the cavity, the wind power unit 13 is fixedly disposed at the bottom of the housing, the trapping light source 12 is used for emitting trapping light capable of attracting spodoptera litura, and the wind power unit 13 sucks air into the cavity through the opening.

The solar cell panel 14 is used for supplying power to the wind power unit 13 and the trapping light source 12, and the top end of the shell 11 is also provided with a hook 15, so that the trap can be conveniently hung through the hook 15.
Preferably, the width of the opening is 20cm to 25 cm. In this particular embodiment, the width of the opening is 22 cm. Most of air-suction traps in the market have the upper and lower heights of an insect inlet which are mostly less than 16cm, and the spodoptera litura has a large body shape, so that the individual flapping light cannot be captured by the air-suction traps. Therefore, according to the body type characteristics of the prodenia litura, the upper and lower heights of the insect inlet of the insect trap are adjusted to be 20 cm-25 cm, and the rate of trapping the prodenia litura is improved.
In the experiment, the field time-phased statistics shows that the spodoptera litura female and male moths have obvious light-up rhythms, wherein the light-up peak of the female moths is expressed in 1-3 h after the dark period, namely 19: 00-22: 00, in the time period, female prodenia litura is mainly trapped; the male moths are shown in 6-8 h after the dark period, namely 1: 00-4: 00. can improve the trapping effect on the prodenia litura female and male moths.
During the period, the non-target insects comprise the dragon louse, the water tortoise shell, the ladybug, the lacewing beetle, the foot bug and the like, wherein the detection wavelength of the water beetle is reported to be 562nm, the detection wavelength of the harmonia axyridis is reported to be 500nm, 605nm, 550nm and the detection wavelength of the lacewing beetle is reported to be 562nm and 524nm, and the like, but not in the wavelength range. The statistics of main natural enemies in the field shows that the light-up rhythm of the beetles and the ladybug does not have a peak, and the light-up peak in the latter half night does not overlap with the light-up peak of the spodoptera litura female moth, so that the light-up time is shortened by switching on the light in a staggered mode, and the mistaken killing of the natural enemy insects can be reduced.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
