The invention relates to a pest trapping and catching device, which belongs to the field of tobacco field pest control and mainly comprises a support rod, a heavy plate, a pest trapping disc, an extension rod, locking bolts, a pest trapping lamp, a yellow plate and a solar photovoltaic module. The pest trapping and catching device integrates the yellow plate, the pest trapping lamp and the pest trapping disc to prevent multiple pests from damaging tobacco; meanwhile, the height of the extension rod can be adjusted through the locking bolts at different growth stages of the tobacco plant, so that the top end of the yellow plate of the pest trapping and catching device is always higher than that of the tobacco plant, the pest trapping lamp is positioned at the middle part, the pest trappingdisc is positioned on the field ground to trap crawling pests on the ground, so that the whole tobacco plants can be prevented from being damaged by pests; in addition, the electric energy required bythe pest trapping lamp is provided through solar photovoltaic power generation, so that the loss of traditional electric energy is reduced, and the tobacco planting cost is saved; and at the same time, the heavy plate is arranged at the bottom of the support rod to increase the stability of the pest trapping and catching device and prevent the device from tipping over in the field.
