[0002] In the work of vector control, it is often necessary to collect wild mosquito eggs and raise them for a certain period of time in order to conduct mosquito resistance experiments and identify species.

[0003] Existing mosquito breeding devices are mainly made of gauze structures, which make it difficult to observe the hatching status of mosquito eggs. The containers containing water and mosquito eggs and adult mosquitoes are in the same space, which can easily cause adult mosquitoes to drown and reduce the hatching rate of mosquitoes. In addition, when adding feed and observing the growth status of young mosquitoes, it is often necessary to open the mosquito cage gauze and take out the containers containing water and mosquito eggs, which can easily spill and increase the risk of adult mosquitoes escaping.

[0004] For this purpose, a mosquito larvae rearing and observation device is proposed. Utility Model Content

More specifically, water and insect eggs are placed inside the breeding box 5. The hatched adult mosquitoes pass through the flight hole 10 and enter the inside of the mesh cover 7. When collecting mosquitoes above, the flight hole 10 can be covered to prevent the mosquitoes from escaping. When feeding, the limit of the locking mechanism 9 is released, and the breeding box 5 and the cone 6 can be separated, so that feed can be added to the inside of the breeding box 5. The shape of the cone 6 can prevent the adult mosquitoes from escaping and drowning due to reverse flight, and is conducive to screening adult mosquitoes with strong flying ability and good condition for testing. By releasing the limit of the docking component 8, the mesh cover 7 can be disassembled to collect adult mosquitoes. The positioning circle 4 and the breeding box 5 can be controlled to move up and down through the height adjustment component 3, so as to facilitate the observation of mosquitoes at different heights.

[0025] The docking assembly 8 includes an elastic band 801, and the elastic band 801 is fixedly connected to the bottom end of the net cover 7. The surface of the cone 6 is provided with an annular groove 802, and the elastic band 801 is sleeved on the inner wall of the annular groove 802. It should be noted that the hatched adult mosquitoes will fly out through the flight hole 10 and enter the interior of the net cover 7. The net cover 7 can be fixed above the cone 6 by the cooperation of the elastic band 801 and the annular groove 802.

[0026] The locking mechanism 9 includes an insert block 901, and the insert block 901 is fixedly connected to the cone 6, a positioning sleeve 902 is fixedly connected to the surface of the feeding box 5, and the inner wall of the positioning sleeve 902 is movably connected to the insert block 901, a support step 907 is provided on the top of the inner wall of the feeding box 5, and the bottom end of the cone 6 is in contact with the surface of the support step 907, and the locking mechanism 9 also includes a positioning component for limiting the insert block 901 and the positioning sleeve 902. More specifically, the positioning component is used to release the limit of the insert block 901 and the positioning sleeve 902, and the insert block 901 is pulled upward, so that the insert block 901 is separated from the inner wall of the positioning sleeve 902, and the bottom of the cone 6 is separated from the support step 907, so that the cone 6 and the feeding box 5 can be disassembled, so that feed can be fed into the inside of the feeding box 5.

[0027] The positioning assembly includes a mounting cavity 903, and the mounting cavity 903 is opened inside the plug block 901, the inner wall of the mounting cavity 903 is fixedly connected with a spring 904, the free end of the spring 904 is fixedly connected with a protrusion 905, and the surface of the positioning sleeve 902 is penetrated with a positioning hole 906, and the inner wall of the positioning hole 906 is movably connected with the protrusion 905.

More specifically, by rotating the knob 302, the screw rod 301 is driven to rotate, and the connecting frame 303 is driven to slide along the surface of the sliding column 304 under the action of the thread, thereby driving the positioning ring 4 and the feeding box 5 to move up and down, thereby facilitating the observation of mosquitoes inside the feeding box 5 and the net cover 7.

[0029] The inner wall of the positioning ring 4 is fixedly connected with a rubber pad, and the breeding box 5 and the cone 6 are both made of transparent materials. It should be noted that by arranging the rubber pad, the friction between the inner wall of the positioning ring 4 and the breeding box 5 is increased, so that the breeding box 5 is placed more stably, and by arranging the transparent material, it is convenient to observe the mosquitoes in the breeding box 5 and the cone 6.

[0031] In summary: water and insect eggs are contained in the feeding box 5, and the hatched adult mosquitoes pass through the flight hole 10 and enter the inside of the net cover 7. When collecting mosquitoes above, the flight hole 10 can be covered to prevent the mosquitoes from escaping. When feeding, the limit of the locking mechanism 9 is released, and the feeding box 5 and the cone 6 can be separated, so that feed is added to the feeding box 5. The shape of the cone 6 can prevent the adult mosquitoes from escaping and drowning due to reverse flight, and is conducive to screening adult mosquitoes with strong flying ability and good condition for testing. By releasing the limit of the docking component 8, the net cover 7 can be disassembled to collect adult mosquitoes. The positioning ring 4 and the feeding box 5 can be controlled to move up and down by the height adjustment component 3, so as to facilitate the observation of mosquitoes at different heights. The effect of facilitating the hatching and observation of mosquito larvae is achieved in use, and water and adult mosquitoes can be effectively separated to avoid the drowning of adult mosquitoes. In addition, disassembly and assembly are more convenient, making it more convenient to add feed and avoiding splashing and escape of adult mosquitoes.
