Description

Technical Field

[0001] The present application relates to the technical field of pest sampling, and more specifically, to an agricultural pest sampling device. Background Art

[0002] Crops are attacked by various pests and diseases during their growth, which leads to slow growth and reduced yield. By sampling and testing pests and diseases, the presence of pests and diseases can be discovered in time, and effective prevention and treatment measures can be taken for the sampled pests and diseases, thereby ensuring the healthy growth of crops. An agricultural pest and disease sampling device is proposed in the existing announcement number CN216088436U. The device is provided with two rotatably connected clamping rods, and an elastic strip is provided between the two clamping rods and two insect catching covers to achieve the insect catching function. Only one hand is required to hold one end of the two clamping rods. , adjust the two insect-catching covers to open and close continuously, open them before catching insects, and when the pest is placed between the two insect-catching covers, quickly relax the hand, so that under the push of the elastic force of the elastic strip, the two insect-catching covers are relatively fitted to trap the pests therein, and the operation is labor-saving. With respect to the above-mentioned related technologies, the utility model inventor believes that the following defects still exist: when the sampling device in the comparative literature is used, due to the short overall structure design, the use and portability need to be improved. The operator needs to bend down when taking samples, which leads to high physical labor intensity, and it is inconvenient to check the physiological condition of the sampled pests and diseases. In view of this, we propose an agricultural pest and disease sampling device. Utility Model Content
