However, due to the action of glue, it will lead to the death of the collected specimens, and even destroy the specimens of the investigation objects, especially the unknown species, which is even more difficult to identify, and micro arthropods are more vulnerable to damage

Embodiment 1
[0026] Embodiment 1: Electrostatic adsorption to insects
[0027] In the laboratory, put 10 citrus whiteflies Dialeurodes citri (Ashmead) into a plastic petri dish, cover the petri dish, some citrus whiteflies were adsorbed on the wall of the petri dish, and some wings were firmly adsorbed on the wall. If you rub your hands on the outer wall of the petri dish, the citrus whiteflies will be absorbed more firmly, and even move with your hands.
[0028] The same experimental results can also be repeated on the whitefly Bemisia tabaci (Gennadius) and some other insects.
Embodiment 2
[0029] Embodiment 2: The electrostatic effect display of the insect checking board
[0030] Cover a layer of transparent soft plastic film with a smooth surface on a square, A4-sized hard plastic board to form a bug check board.
[0031] Split the roll paper for daily use in the middle, then cut it into thin strips, and open it layer by layer to form a single layer of thin paper strips with a width of about 1 mm. When the distance is about 7-10cm, the paper strip will stand up and continue to approach, and the paper strip will be adsorbed on the insect checking board.
[0032] In the same experiment, there was little or no adsorption of the traps on non-smooth surfaces.
Embodiment 3
[0033] Embodiment 3: The electrostatic action of insect checking board absorbs insects
[0034] Cover a layer of transparent soft plastic film with a smooth surface on the rigid plastic plate with a grid and A4 size to form a worm checking board, put 10 citrus whiteflies Dialeurodes citri (Ashmead) on the worm checking board, and citrus powder Lice are adsorbed on the pest inspection board, and some wings are firmly adsorbed on the wall. If you rub your hands on the pest inspection board, the citrus whitefly will be adsorbed more firmly and even move with your hand.
[0035] The same experimental results can also be repeated on the whitefly Bemisia tabaci (Gennadius) and some other insects.

Abstract
The invention discloses a standardized investigation method for agricultural and forestry pests. Cover a layer of transparent soft plastic film with a smooth surface on a blue, yellow or red hard plastic board with a grid to form a pest inspection board; when conducting field investigations on fruit trees or agricultural and forestry plants, randomly sample according to conventional technical requirements For the sample plant, investigate in the four orientations of the sample plant, southeast, northwest, select a branch in each orientation, place the insect checking board under the branch of the sample plant, and then knock the branch 3-5 times, the pests will fall on the insect checking board, use the insect checking board to The squares of the plate are counted or / and the soft plastic film is bent, the insects are poured into the collection bottle, and the living specimens are directly collected for taxonomic identification or establishment of experimental populations. The invention is fast, convenient and easy to operate, and at the same time, it overcomes the influence of human naked eye observation and individual differences in results among different investigators on data accuracy in traditional pest monitoring and investigation. It can be applied to field surveys of fruit trees, vegetables and garden plants. It is of great significance to pest monitoring and pest forecasting.
Description
Technical field: [0001] The invention belongs to the field of plant protection, and in particular relates to a standardized investigation method for agricultural and forestry pests, which can be used for pest monitoring, pest forecasting and the like. Background technique: [0002] Field investigation of agricultural and forestry pests is the most direct way to understand the occurrence of field pests, and it is also a common technical means for plant protection forecasting. Knowing the occurrence density of pests through pest investigation is the key technology to master their occurrence rules and dynamics, and to do a good job of forecasting. Traditional pest forecasting surveys include visual observation, sweeping net sampling and yellow board monitoring. [0003] Among them, field survey by naked eye is considered to be one of the most commonly used and effective techniques, and the data is intuitive and effective, but this method also has unavoidable shortcomings, such...
