The study found that solar intelligent insect traps are the main rice pests (ricehoppers, brown planthoppers, dorsal saccharins, and rice stem borers, etc.), and major vegetable pests (Plutella xylostella, Spodoptera litura, and S. litura, etc.) And corn borer and so have a good trapping effect.
The beacons of the natural enemies such as the armored beetle, covert winged insect and black-shouldered green-nosed beetle peak mainly in the early evening and early morning, especially the hidden winged beetles. The fluttering lights are more active in the early morning and they rarely flutter at midnight; Leafhoppers, rice planthoppers, borerworms, corn borers, diamondback moths, Spodoptera lituras, and other pests flew more at midnight, and Spodoptera litura was found only during the second half of the night. Therefore, it should be possible to selectively turn on the lights during the peak period of insect pests, and turn off the lights during the active period of natural enemy flies, which is conducive to ecological control of pests.
Calculating the timing of the gold flutter lamp of various types of insects has an important role and can provide a technical basis for the selective trapping and killing of such insects. According to the results of this study, it can be set to automatically turn off the trapping lamp at 0:30 in the evening, so that it can not only trap the main pests in rice fields, but also protect the natural enemies of pests to some extent.
