TECHNICAL FIELD

[0001] The utility model relates to a kind of oviposition devices of chinch bug, belong to insect experimental device technical field. BACKGROUND

[0002] Chinch bug ( Riptortus pedestris ), belong to Hemiptera (Hemiptera) Alydidae (Alydidae), is polyphagous piercing-sucking mouthpart pest. Chinch bug host is widely, can endanger crop, vegetable and fruit tree etc. 200 or so plants, but its main harm soybean etc. Leguminosae, cause soybean to drop flower, drop pod and shriveled grain etc. At present, when doing the experiment about chinch bug egg, there is egg taking technical bottleneck:

[0003] 1. chinch bug oviposition bias problem

[0004] We found that chinch bug female adult is biased to oviposition in high place in experimental process, and like to oviposition on the yarn rearing cage. In addition, chinch bug also tends to choose relatively thin yarn as its oviposition site, especially the yarn in the corner of rearing cage, which increases the difficulty of egg taking.

[0005] 2. the integrity problem of egg taking

[0006] Chinch bug egg is about 1.3mm long and about 1mm wide, individual is relatively small, and chinch bug just laid egg surface has a layer of mucus and sticks the egg firmly on rearing cage or yarn, is extremely easy to destroy egg when taking down, resulting in the low integrity of egg taken. SUMMARY

[0007] The utility model aims at providing a kind of chinch bug oviposition device. The oviposition device not only is convenient for efficiently collecting chinch bug egg, but also is convenient for subsequent experimental operation, such as observation of egg, monitoring of hatching condition and other relevant egg experiments.

[0023] The utility model is further described below in combination with the drawings and examples, but is not taken as the basis for limiting the utility model.

[0024] The utility model discloses an embodiment: a kind of oviposition device of point honey fringe bug, including the box body 1 of top opening, box cover 2 is arranged on the box body 1 upper, first gauze 3 is arranged on box cover 2, the center of first gauze 3 is provided with cotton ball placement hole 4, cotton ball 5 is placed at cotton ball placement hole 4, and gauze 6 is arranged on the first gauze 3 of the periphery of cotton ball placement hole 4 and is vertically into the box body 1.

[0025] The utility model discloses a device through the simulation natural environment, provide suitable growth and feeding condition for point honey fringe bug, and simultaneously through modular design, it is convenient to carry out the collection of egg, and the device includes box body 1, box cover 2, first gauze 3, gauze 6 and the cotton ball 5 of sucking foot honey water.Box body 1: for the cylindrical plastic box of diameter 12cm, high 16cm;Box cover 2 is provided with first gauze 3, guarantees its ventilation, and box cover 2 guarantees easy to detach.In first gauze 3, gauze 6 of length 15cm is fixed, and one cotton ball 5 of sucking foot honey water is placed at the cotton ball placement hole 4 of the center of first gauze 3, to guarantee the basic survival needs of point honey fringe bug, and box body 1 and box cover 2 are detachable structure, guarantee the collection of point honey fringe bug egg and its reusability.The utility model uses above-mentioned structure, with simple structure, easy to operate's advantage.In use process, point honey fringe bug will adhere on gauze 6 and carry out oviposition, when needing to collect point honey fringe bug egg, box cover 2 is taken off from box body 1, then gauze 6 is taken off from first gauze 3, can conveniently carry out the collection of point honey fringe bug egg, and can replace new gauze 6 on first gauze 3.

[0026] Second gauze 7 is fixed at the opening of box body 1, and the center of second gauze 7 is also provided with cotton ball placement hole 4, and the position of cotton ball placement hole 4 on first gauze 3 is opposite to the position of cotton ball placement hole 4 on second gauze 7, the mesh of second gauze 7 is larger than the mesh of first gauze 3, and gauze 6 is vertically into box body 1 after passing through the mesh of second gauze 7.Set with second gauze 7 is to block box body 1 after point honey fringe bug is loaded into box body 1 or after box cover 2 is taken off from box body 1, can pass through second gauze 7 and block box body 1, avoid point honey fringe bug from running out of box body 1.The mesh of second gauze 7 is larger than the mesh of first gauze 3, facilitate gauze 6 to pass through the mesh of second gauze 7, when taking down box cover 2 from box body 1, as far as possible avoid the egg adhered on gauze 6 and the mesh of second gauze 7 touch, cause egg to be scraped down.After box cover 2 is covered on box body 1, press down cotton ball 5 and make it move from the cotton ball placement hole 4 on first gauze 3 to the cotton ball placement hole 4 on second gauze 7, facilitate point honey fringe bug to suck the honey water in cotton ball 5.First gauze 3 and second gauze 7 guarantee the ventilation of device.

[0027] After the first stage of the dot honey rim bug is put into the box body 1, the cotton ball placing hole 4 on the second gauze 7 is sealed by using adhesive tape during the process of setting the second gauze 7 on the box body 1, and after the box cover 2 is covered on the box body 1, the adhesive tape is removed by using tweezers, and then the cotton ball 5 is put into the cotton ball placing hole 4 on the second gauze 7, so that the cotton ball placing hole 4 on the second gauze 7 is sealed by the cotton ball 5, and it is also convenient for the dot honey rim bug in the box body 1 to suck the honey water in the cotton ball 5.

[0028] The box body 1 is provided with a plurality of clamping grooves 8 on the top end outer wall, the second gauze 7 is covered on the opening of the box body 1, and the second gauze 7 is fixed on the top end outer wall of the box body 1 by the rubber ring 9, and the rubber ring 9 is clamped into the clamping groove 8, which can quickly fix the second gauze 7 on the box body 1. The box cover 2 is slidingly sleeved on the box body 1, when the box cover 2 is sleeved on the top end outer wall of the box body 1, the inner wall of the box cover 2 is in contact with the rubber ring 9, since the rubber ring 9 is clamped into the clamping groove 8, the rubber ring 9 cannot be moved together with the box cover 2 during the up-down sliding process of the box cover 2, but the mutual friction force between the rubber ring 9 and the inner wall of the box cover 1 can make the box body 1 and the box cover 2 be well clamped together, so as to ensure firm connection.

[0029] The first gauze 3 is fixed with a plurality of hooks 10, and one gauze 6 is sleeved on each hook 10. After the box cover 1 is taken off from the box body 1, the gauze 6 with eggs attached can be quickly taken off from the hook 10, so as to facilitate replacement of new gauze 6.

[0030] The length of the gauze 6 is less than the depth of the box body 1, so as to avoid the bottom of the gauze 6 from contacting the inner bottom of the box body 1, and make the gauze 6 be in vertical state in the box body 1.

[0031] The box body 1 is a transparent plastic box, which is convenient for observing the activity of the dot honey rim bug in the box body 1.
