Embodiment 1

[0025] Taking the monitoring of flower thrips on cowpea as an example, put them into the same cowpea greenhouse where thrips damage occurred at 9:45-10:15 in the morning on a sunny day, and investigate the thrips on each plate after 2h, 4h and 6h after putting them in. The number of thrips heads, the specific method process is:

[0026] (1) The color plate 1 is sandwiched between the two plastic sealing plates 4, and the two plastic sealing plates 4 are sealed and connected at the edge positions, wherein the thickness of the plastic sealing plate 4 is 0.10 mm, the thickness of the white plate is 0.06 mm, and the round hole The diameter is 3.0mm, the hole distance is 6cm, and the adhesive layer 2 is coated on the outside of the two plastic sealing plates 4;

[0027] (2) by means of the cowpea field branches and stems are intricately wound around, two S-shaped hooks 6 can be utilized to hang the plastic sealing plate 4 on the designated height of the cowpea plant (the lower edge...

Embodiment 2

[0030] Taking the monitoring of flower thrips on cowpea as an example, put them into the same cowpea greenhouse where thrips damage occurred at 9:45-10:15 in the morning on a sunny day, and investigate the thrips on each plate after 2h, 4h and 6h after putting them in. The number of thrips heads, the specific method process is:

[0031] (1) The color plate 1 is sandwiched between the two plastic sealing plates 4, and the two plastic sealing plates 4 are sealed and connected at the edge positions, wherein the thickness of the plastic sealing plate 4 is 0.30 mm; the thickness of the white plate is 0.12 mm, and the round hole The diameter is 3.0 mm, the hole distance is 12 cm, and the adhesive layer 2 is coated on the outside of the two plastic sealing plates 4;

[0032] (2) by means of the cowpea field branches and stems are intricately wound around, two S-shaped hooks 6 can be utilized to hang the combination color plate 1 at the designated height of the cowpea plant (the lower...

Embodiment 3

[0035]On the basis of Example 1, replace the white board with color board 1 of other colors: sky blue, light blue, purple, pink, light green, light yellow, dark red, dark green, dark blue, orange yellow, Golden yellow, black and colorless (i.e. do not release color plate 1), all the other are identical with embodiment 1.

Abstract

The invention relates to the technical field of agriculture, in particular to a device for preventing thrips in a cowpea field. The device includes a color plate, suspension components, two plastic package plates and two adhesive layers; the color plate is arranged between the two plastic package plates, the plastic package plates are in seal connection at the edge position, the suspension components are arranged on the upper portions of the two plastic package plates, and the outer sides of the two plastic package plates are coated with the two adhesive layers respectively. In this way, the front surface and the back surface of the color plate are provided with the two plastic package plates respectively, the two plastic package plates are formed into a whole through thermoplastic sealing, and the outer surfaces of the two plastic package plates are uniformly coated with the adhesive layers; the suspension components are arranged on the upper portions of the two plastic package plates, stems of cowpea plants in the cowpea field can thus twine in a staggered mode, the suspension components can be used for hanging the color plate to the specified height and orientation of the cowpeaplants, and the combination color plate can be glued regularly, so that the thrips in the cowpea field can be effectively and sustainedly controlled.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a device for preventing thrips in a cowpea field. Background technique [0002] At present, cowpea [Vigna unguiculata (L.) Walp.] is an important planted vegetable in my country, and it is often damaged by thrips in the process of planting cowpea. Thrips are insects that live on plant sap. The larvae are white, yellow, or orange, and the adults are brown or black. Ingestion can cause leaf and flower damage. Spraying pesticides is a common method to control thrips in cowpea fields, but because thrips have developed high resistance to common chemical pesticides, the effect of spraying pesticides on the field is getting worse and worse with age , which in turn led some farmers to arbitrarily increase the use of pesticides in order to achieve the desired control effect, which led to the frequent occurrence of "poisoned cowpea" incidents in various places. In order to reduce ...
