The utility model discloses a novel fish lure with noctilucent effect, including the fish bait main part, the lateral surface of fish bait main part is equipped with two first recess and second recess, and the first recess and second recess are symmetric distribution, and the both ends of fish bait main part are installed with two connecting rings, the utility model discloses a first recess and second recess etc. are arranged, and the fishing line and the fish hook are installed on the fish bait main part through two connecting rings, when the fishing line is pulled upward when the fish bait main part is thrown in the water and fishes, the fish bait main part will pull the surrounding water, and the position and shape of first recess and second recess determine the flow direction and speed of water, after the water enters first recess and second recess, due to the change of the flow rate of water around because of the water distribution, the air bubble will be produced, these air bubbles rise in the water, form a kind of dynamic bubble flow, and the bubble flow can simulate the air bubble produced when the aquatic insects, small fish and other organisms swim and struggle in the water, attract the predatory fish to come and attack, and then play the effect of fish lure.

The present invention provides a biological passage adapted to animals with different swimming behaviors, comprising a river-blocking structure arranged on a river channel and a biological passage arranged in conjunction with the river channel; the biological passage is connected to the river-blocking structure; the biological passage comprises channel one, channel two, and channel three, and channel one, channel two, and channel three can be arranged vertically in a mixed arrangement or arranged horizontally side by side. The present invention provides an effective passage along the river-blocking structure to different habitats along the river bank with different water depths, different flow rates, different flow states, and different bottom types, so that different animals can choose to enter. The passage can also provide an effective passage across the river-blocking structure to different habitats for different fish species, fish of different sizes, aquatic insects, shrimps, crabs, and amphibians such as frogs and snakes in the same river, so that different animals can choose to enter.

The invention discloses wetland aquatic insect investigation and sampling equipment, and belongs to the technical field of wetland aquatic insect sampling, the wetland aquatic insect investigation and sampling equipment comprises a sampling platform, the top surface of the sampling platform is slidably connected with a first connecting frame, a first driving mechanism is arranged between the first connecting frame and the sampling platform, and the first connecting frame is internally slidably connected with a first connecting plate; a second driving mechanism is arranged between the first connecting plate and the first connecting frame, the top surface of the first connecting plate is fixedly connected with a sampling driving mechanism, and the sampling driving mechanism is fixedly connected with a sampling barrel. When the wetland aquatic insects need to be sampled, the sampling platform is moved to a sampling position, then the sampling barrel is descended to the position below the water surface through the sampling driving mechanism, the wetland aquatic insects are sampled, after sampling is completed, the sampling barrel is ascended through the sampling driving mechanism, then a first connecting frame slides to the position above the collecting mechanism, and the sampling barrel is lifted through the sampling driving mechanism. The sampling barrel descends, and the wetland aquatic insects are put into the collecting mechanism for further observation and experiment.

The invention discloses an insect interference device and method, and relates to the field of insect behavior regulation and control, the device comprises a power module and an optical module, the optical module comprises at least one reflection unit driven by the power module to regularly move, and the reflection unit is configured to reflect the insect behavior in the movement process. The device periodically reflects ambient light or light emitted by a special light source so as to generate a dynamic flickering light signal with the frequency ranging from 5 Hz to 1000 Hz, and the device is used for simulating various natural visual signals (such as flapping wings, water surface light reflection and flower honey guide) having biological significance to insects or creating'supernormal stimulation 'which does not exist in the nature, and is used for simulating the natural visual signals (such as flapping wings, water surface light reflection and flower honey guide). Therefore, specific behavior interference can be performed on different target insect groups (such as pollinating insects, aquatic insects and predatory insects).

The utility model relates to the field of insect collecting devices, and discloses an aquatic insect collecting suspension device which comprises a storage box and a connecting structure, the storage box and the connecting structure are arranged in a sleeved mode, four connecting rods are fixedly arranged on the periphery of the connecting structure, and floating balls are fixedly arranged on the sides, away from the connecting structure, of the four connecting rods. Supporting rods are fixedly arranged at the positions, close to the two sides, of the upper end of the connecting structure, a top plate is fixedly arranged at the upper ends of the two supporting rods, a through groove is formed in the middle of the upper end of the top plate, four fixing rods are fixedly arranged on the inner wall of the through groove, and a protective shell is fixedly arranged on the opposite sides of the four fixing rods. According to the device, the fan continuously blows air, insects enter the device after being attracted by lamplight and are stored in the storage box under the action of the funnel and the air, an opening in the bottom of the funnel is small to prevent the insects from escaping, the device is further provided with a detachable connecting structure, the storage box is convenient to take down, and cleaning and overhauling are convenient.

The present invention discloses an aquatic insect counting device, which relates to the field of insect counting. It includes a fixed module arranged on the shore, and a capture and counting module located in the water and connected to the fixed module through a connecting rod. The capture and counting module includes an expansion counting device connected to the fixed module through a connecting rod, two direct counting devices symmetrically arranged on the outer wall of the expansion counting device, and a lure device arranged at the inlet of the direct counting device. The device in the present invention can automatically lure, capture and count aquatic insects, and can effectively avoid the influence of insect aggregation on counting. Through the lure device, it is convenient to lure insects, and at the same time, when insects gather, the lure route can be switched to alleviate the phenomenon of insect aggregation. Through the direct counting device, it is convenient to count and collect the trapped aquatic insects with a density lower than the set density, and at the same time, the aquatic insects with a density higher than the set density can be moved into the expansion counting device. The expansion counting device can count aquatic insects in a large space and can suck out the liquid to prevent the liquid from affecting the insect counting.
