Description

Technical Field

[0001] The utility model belongs to the technical field of insect breeding devices, in particular to a fruit fly toxicity determination device. Background Art

[0002] Fruit flies are a general term for insects of the family Tephritidae in the order Diptera. They are a type of pest that seriously harms fruit trees and vegetable production in my country. Among them, fruit flies are the most serious, including the citrus fruit fly, citrus fruit fly, citrus fruit fly, pumpkin fruit fly, melon fruit fly, guava fruit fly, etc. After mating, female insects lay eggs inside vegetables and fruits, and the larvae feed on the flesh of vegetables and fruits, causing them to rot and deteriorate, fall off prematurely, and lose their commercial value. At present, the control plan for fruit flies is diverse, mainly based on chemical pesticides, combined with the use of sex attractants, food attractants, release of parasitic wasps, and garden cleaning. Among the methods for determining the toxicity of chemical agents, the drug film method and the drip method are mainly used to determine the contact effect of the agent. Relatively speaking, the method for determining the toxicity of stomach poisons for insects with licking mouthparts is more accurate.

[0003] The existing device for determining the toxicity of the stomach poison of fruit flies can refer to the patent "A method for determining the toxicity of the stomach poison of the orange fruit fly using a simple device" (CN104770340B). The device for determining the toxicity of the stomach poison of the orange fruit fly in this patent includes a cotton ball, a pipette tip, a disposable plastic cup, a gauze and other structures. The device has a simple structure, can reduce the contact between the orange fruit fly and the agent, avoid the interference of the contact killing effect, and can accurately measure the toxicity of the stomach poison. However, the device needs to make multiple devices when performing separate male and female measurements and multi-gradient concentration measurements. The area occupied during the experiment is large, and it takes a lot of time to clean them one by one after the experiment. In addition, the insect entry setting of the device is not perfect, the insect opening is too large and there is no obstruction, which easily causes the insects to fly away, and if the insects of the other sex are accidentally mixed in when the male and female are measured separately, they cannot be taken out, and the whole cup can only be re-inserted, which reduces the efficiency of the experiment.

The following is an explanation of the embodiments of the present invention based on its overall structure.

[0036] Example 1

[0037] like Figure 1 As shown, a fruit fly toxicity determination device comprises a tank body 1, a cover 2, a Pasteur pipette suction bag 3, a partition plate 4 and a gauze cover 5. The utility model provides a Pasteur pipette suction bag 3 on the cover 2 for feeding venom, thereby reducing the contact between fruit flies and venom and accurately measuring the stomach toxicity of the agent. By providing a partition plate 4 in the tank body 1, the tank body 1 is divided into several insect feeding areas, and male and female determinations and multi-gradient concentration determinations can be performed simultaneously, thereby reducing the experimental area.

[0038] Specific, combined Figure 1-2 The lid 2 is disposed on the top of the tank body 1, and at least three sockets 6 are formed on the lid 2, and the Pasteur straw suction bag 3 is detachably inserted in the sockets 6. Figure 3 , one end of the Pasteur straw suction capsule 3 is sealed and the other end is open, and the open end is a closed funnel shape. Preferably, the Pasteur straw suction capsule 3 has an outer diameter of 12mm, a length of 35mm, and an opening width of 4mm. The Pasteur straw suction capsule 3 can be purchased from an existing plastic dropper, the straw part is cut off, and the suction capsule part is retained for use. When in use, after squeezing the Pasteur straw suction capsule 3 to inhale the liquid medicine, it is inserted into the socket 6. The open end of the Pasteur straw suction capsule 3 extends into the tank body 1 for fruit flies to inhale. If the venom test is not performed, the Pasteur straw suction capsule 3 can be inserted upside down at the socket 6, and the socket 6 can be sealed to prevent the fruit flies from escaping, and starvation treatment can be performed, which is simple and practical. The opening width of the Pasteur straw suction capsule 3 is about 4mm, which is convenient for fruit flies to inhale, and the liquid medicine in the Pasteur straw suction capsule 3 will not fall off. If the opening of the Pasteur straw suction bag 3 is too small, after the fruit fly sucks the liquid medicine on the surface, the liquid medicine in the Pasteur straw suction bag 3 is not easy to be replenished downward, which is not conducive to the fruit fly's sucking.

[0039] In other embodiments, several support rods may be provided on the top of the cover 2, wherein the height of the support rods is higher than the height of the Pasteur pipette suction bag 3, so as to facilitate stacking of multiple fruit fly toxicity determination devices and reduce the device footprint.

[0040] Combination Figure 4The tank body 1 is a hollow cylinder with an opening at the top. A vent hole 7 is provided at the upper part of the tank body 1. An insect release opening 8 is provided at one side of the lower part of the tank body 1. The insect release opening 8 is provided with the gauze sleeve 5. The insect release opening 8 is provided at the lower part of the tank body 1 and is equipped with a gauze sleeve 5. Compared with releasing the insects with the lid opened, the insects are not easy to fly away. By providing the insect release opening 8 at the lower part of the tank body 1 and providing the gauze sleeve 5 at the insect release opening 8, when in use, the fruit flies can be directly placed near the lid 2 of the tank body 1 through the insect release opening, so that the fruit flies can feed on the liquid in the Pasteur straw suction bag 3. At the same time, if the insects of the other sex are accidentally mixed in when the male and female are measured separately, they can be caught through the insect release opening 8, without taking out the fruit flies in the area and re-catching them, thereby improving the fault tolerance of the device.

[0041] In other embodiments, a fixing ring is provided at one end of the gauze cover 5 away from the tank body 1, so as to facilitate the operation of taking and releasing the insects.

[0042] Combination Figure 1 The tank body 1 is provided with a partition plate 4, and the partition plate 4 divides the tank body 1 into at least two insect feeding areas. Figure 6 In this embodiment, there are three partition plates 4, which divide the tank body 1 into three insect feeding areas. Two Pasteur straw suction capsules 3 are installed on the lid 2 facing each insect feeding area. Of course, in other embodiments, different numbers of partition plates 4 can also be set, and different numbers of Pasteur straw suction capsules 3 can be matched. In this embodiment, the top of the partition plate 4 is fixed to the lid 2 by glue or the like. When the lid 2 rotates relative to the tank body 1, the Pasteur straw suction capsule 3 and the partition plate 4 also rotate. That is, by rotating the lid 2, different insect feeding areas can be aligned with the insect release port 8 in turn, which is convenient for taking out and putting in fruit flies from different insect feeding areas.

[0043] In other embodiments, the partition may also be fixed in different ways. Figure 6 A column 9 is fixed at the center of the cover 2, and vertical slots 10 are evenly spaced along the circumferential direction on the column 9, and one side of the partition plate 4 is detachably inserted on the column 9. The number of partition plates 4 and the installation positions of the vertical slots 10 are selected as needed to obtain the number of insect feeding areas to meet more experimental requirements.

[0044] In other embodiments, a feeding box is fixed to the lower portion of the partition.

[0045] In this embodiment, the tank body 1 is transparent and the partition is opaque, which is convenient for observing fruit flies in different insect feeding areas.

[0046] The device is used for the determination of the toxicity of the stomach poison of the orange fruit fly. The device is assembled first. Six sockets 6 with a diameter of about 1.2 cm are opened on the lid 2. The partition is cut and fixed to the lid 2 by glue. At the same time, a number of 1 mm diameter pores are opened on the upper part of the tank body 1 by an electric soldering iron, and an insect release opening 8 is also cut out by an electric soldering iron on the lower part of the tank body 1. The insect release opening is length * width = 8cm * 9cm, and the gauze sleeve 5 is fixed at the insect release opening 8. Then the lid 2 is covered on the tank body 1, and the Pasteur pipette suction capsule 3 is inverted first. After preparation, the adult orange fruit fly is rotated into different insect feeding areas through the insect release opening 8 through the partition plate. After starvation for 24 hours, the Pasteur pipette suction capsule 3 is squeezed into the medicine liquid or water and inserted into the socket 6, so that the orange fruit fly can suck the medicine liquid in the Pasteur pipette suction capsule 3. After 24 hours, the mortality rate of each area is recorded. This device can set multiple treatment groups at the same time, which is conducive to the development of the experiment.

[0047] In summary, the utility model provides a Pasteur straw suction bag 3 on the lid 2, and the open end of the Pasteur straw suction bag 3 extends into the tank body 1 for fruit flies to suck, which can reduce the interference of contact killing and accurately measure the stomach poison toxicity of the agent. By providing a partition, the tank body 1 is divided into several insect feeding areas, and male and female measurements and multi-gradient concentration measurements can be performed simultaneously, and the number of measurement devices can be reduced, and the experimental area can be reduced. By providing an insect release opening 8 at the lower part of the tank body 1, and providing a gauze cover 5 at the insect release opening 8, if insects of the other sex are accidentally mixed in when performing male and female measurements, they can be caught through the insect release opening 8, without taking out the fruit flies in the area and re-catching them, thereby improving the fault tolerance of the device, or when sampling at different toxicity times is required, sampling can be conveniently performed and continued measurement can be performed.
