[0027] like Figure 10 As shown, the closing device 110 includes a pair of cloth covers 111, a drawstring 112 and an elastic member 113 which are sleeved inside the pair of cloth covers 111. The cloth covers 111 are sewn to the top of the net bag 100, wherein the length of the drawstring 112 is greater than the top circumference of the net bag 100, and the drawstring 112 is at least 50 cm. By fastening the two ends of the drawstring 112, it is further ensured that the net bag 100 is tied tightly outside the tree branch to cover the branches and leaves. The natural diameter of the elastic member 113 is 5-8 cm, and its diameter after elongation and deformation is 30-32 cm. The elastic member 113 is preferably an elastic tendon, and then the elastic member 113 instantly rebounds and contracts the top end of the net bag 100 to wrap the branch, so as to prevent the pests from flying away and failing to be captured.

[0028] Specifically, in order to collect and transfer flying pests, e.g. Figures 2-7As shown in the figure, a pest collector 200 is provided below the bottom end of the net bag 100 for collecting pests and disassembling and transferring them. The pest collector 200 includes a funnel-shaped pest collection hopper 210, a pest collection box 220 rotatably connected to the bottom port of the pest collection hopper 210, and a number of guiding plates 230 annularly and equidistantly embedded in the inner wall of the top end of the pest collection box 220. The upper end of the pest collection hopper 210 is sutured or bonded to the bottom end of the net bag 100. The number of guiding plates 230 is used to cover the top port of the pest collection box 220 and has an opening in the central area. After the pest collection box 220 is rotated and installed at the bottom of the pest collection hopper 210, the number of guiding plates 230 is rotated and rubbed to turn upright, forming a state where the top port of the pest collection box 220 is opened, for collecting pests vibrated and falling into the net bag 100. That is, when the pest collection box 220 is screwed out, the number of guiding plates 230 is in a covered state, leaving only an opening in the central area, so as to align with the mouth of the glass bottle to pour out the pests. The opening in this central area can be covered with the palm when transferring the pest collection box 220 to prevent the pests from flying away.

[0029] The net bag 100 has a diameter of 30 - 32 cm, a height of 32 - 35 cm, and a pore size of 20 mesh, and is woven from nylon. Psyllids are piercing-sucking pests with a tiny body size of 2 - 5 mm, so the 20-mesh net bag 100 with a 1-mm hole is used to capture them. The pest collection box 220 is a cuboid box with dimensions of 10×10×5 cm and is made of pp material.

[0030] Furthermore, a threaded cover 211 is fixedly connected to the bottom port of the pest collection hopper 210, and the two are integrally formed with pp material. A threaded ring 223 threadedly connected to the threaded cover 211 is provided on the outer wall of the top end of the pest collection box 220. A hollow silica gel ring 212 is embedded in the top surface of the threaded cover 211. The longitudinal section of the silica gel ring 212 is wider at the top and narrower at the bottom.

The guiding plate 230 is driven to flip by the contact friction between the silica gel ring 212 and the rubber wheel 231. The hollow design of the silica gel ring 212 is to have space for deformation when continuously squeezed upward by the rubber wheel 231.

[0031] Furthermore, in order to fix the number of guiding plates 230, a number of grooves 221 are annularly and equidistantly opened on the top surface of the pest collection box 220, and a number of concave holes 222 corresponding to and penetrating through the number of grooves 221 are opened on the inner wall of the top of the pest collection box 220. The rotating shaft is inserted and rotated in the concave holes 222, and the rubber wheel 231 is placed in the grooves 221 and protrudes from the top surface of the pest collection box 220, so as to contact and rotate with the silica gel ring 212, thereby driving the rotating shaft and the guiding plate 230 to rotate synchronously.

[0032] The guiding plate 230 is fan-shaped and an inclined surface 232 is provided on its bottom surface, for guiding pests to slide down along the inclined surface 232 from the central area opening when the pest collection box 220 is inverted, and transferring them out of the pest collection box 220 for collection.

[0033] In addition, in order to quickly tighten the net bag 100 top port, such as Figures 8-9 As shown, a net adjusting part 300 is provided on the outside of the net bag 100, which is used to switch the top end of the net bag 100 from an open state to an elastically contracted closed state, thereby automatically wrapping the tree branches; the net adjusting part 300 includes a net supporting member 310 sleeved on the inner side of the top end of the net bag 100, a pair of transmission rods 320 connected to both sides of the net supporting member 310, and a pair of toggle members 330 rotatably connected to both sides of the bottom of the insect collecting bucket 210, the top toggle member 330 triggers the transmission rod 320 to drive the net supporting member 310 to separate from the net bag 100, and the net bag 100 instantly shrinks and wraps the tree branches under the rebound action of the elastic member 113. A closing mouth 311 is provided at the bottom end of the net supporting member 310, and the longitudinal section of the closing mouth 311 is arc-shaped. The inner diameter of the bottom end of the closing mouth 311 is smaller than the inner diameter of the upper end, so that the top end of the net bag 100 is opened and firstly put on the outer wall of the closing mouth 311, and then slides along it to the outer wall of the net supporting member 310, which is convenient for assembly.

[0034] Furthermore, guide rings 214 are symmetrically provided on both sides of the top of the insect collecting bucket 210, and the two are made of PP material to form an integral structure; the transmission rod 320 is slidably sleeved with the guide ring 214 to guide the transmission rod 320 to push the supporting net 310 away from the top of the net bag 100; the bottom outer wall of the guide ring 214 is sleeved with a spring 321, and the spring 321 is located below the guide ring 214. With the help of the guide ring 214, the transmission rod 320 rebounds and drives the supporting net 310 to reset so that it can be inserted into the net bag 100.

[0035] Furthermore, clamp rings 213 are symmetrically provided on both side walls of the threaded cover 211, and the two are made of pp material to form an integral structure; the toggle member 330 is L-shaped and a rotating hole 331 is opened on the side wall at its bending part, and the rotating hole 331 is rotatably connected to the clamp ring 213 through a pin. When grasping the insect collecting box 220, the upper end of the toggle member 330 is lifted by lifting and pushing the lower end, and the upper transmission rod 320 drives the net supporting member 310 to move upward relative to the insect collecting bucket 210, thereby detaching from the top of the net bag 100, and the top of the net bag 100 is closed under the contraction of the elastic member 113.

[0036] When using the vibrating net bag type capture device for monitoring psyllid pests in fruit tree seedling cultivation of the present invention, the top of the net bag 100 is firstly placed on the outside of the supporting net member 310, and then the insect collecting box 220 is tightened in the bottom of the insect collecting bucket 210, triggering a plurality of guide plates 230 to stand up and unfold, and then the insect collecting box 220 is grasped to put the supporting net member 310 on the outside of the branches of the flower buds, young fruits or new shoots where psyllids like to parasitize, and then the net bag 100 is covered; Then, the lower end of the lifting and pushing member 330 is tilted upwards and the upper end is lifted, and the upward pushing transmission rod 320 drives the net supporting member 310 to move upwards relative to the insect collecting hopper 210, so as to disengage from the top end of the net bag 100. The top end of the net bag 100 is then closed instantaneously under the contraction of the elastic member 113 to wrap the branch. Then, the insect collecting box 220 is gently shaken to vibrate the covered branch, so that the insects are shaken down into the net bag 100 and then shaken into the insect collecting box 220. When the insect collecting box 220 is screwed out, a plurality of guiding plates 230 are in a closed state, leaving only an opening in the central area. Then, the pests are poured out by aligning with the mouth of the glass bottle, making it convenient and reliable to capture the jumping and flying psyllid pests, reducing the difficulty of manual capture, timely grasping the dynamic occurrence of the insect situation, giving an early warning in time, predicting the best period for prevention and control, and improving the efficiency of pest control.
