Description

Technical Field

[0001] The utility model belongs to the technical field of insect breeding devices, and particularly relates to a fruit fly breeding device which is convenient for collecting insect eggs. Background Art

[0002] Fruit flies are the common name for the family Tephritidae in the order Diptera. There are about 250 species of fruit flies that directly harm commercially grown or wild fruits or vegetables. They are internationally recognized as dangerous pests and are listed as important quarantine targets in many countries. Fruit flies are herbivorous insects. Their larvae are all cryptic and harm all parts of plants, from roots, stems, leaves, flowers to fruits. Many species are crop pests, among which those that harm fruits are particularly important. For example, the melon fruit fly, the citrus fruit fly, the broad-banded fruit fly and the South Asian fruit fly are all distributed in my country and have caused serious damage in the fields. Reproduction is the key to the growth of pest populations. In-depth research on the reproduction of fruit flies can better prevent and control them.

[0003] Although existing fruit fly rearing devices can provide water, food, etc. well, they are mostly taken out from the cuffs, which is not convenient. In addition, the manufacturing process of some devices is complicated and the operability is not strong, which is not conducive to the observation and collection of fruit fly eggs. The patent "A single-head rearing device for fruit fly pests" (CN20356364U) sets holes in the bottom of the cup to facilitate the collection of eggs, but in actual operation, eggs may be produced inside and not be counted, which reduces the accuracy of the experiment. In addition, the device cannot easily replace feed, and the breeding scale is very small. Utility Model Content

Fruit flies like to lay eggs on hole-shaped objects, and the setting of the egg collecting hole 81 is conducive to collecting eggs. Of course, a small number of fruit flies will lay eggs on the cover plate 8. The egg collecting box 7 is detachably connected to the tank body 1, and the cover plate 8 can be taken out separately, which is conducive to collecting all eggs and improving the experimental accuracy.

[0044] Combination Figure 5 The water feeding device 10 comprises a cotton rope 101 and a water container 102. The water container 102 is filled with water. One end of the cotton rope 101 is placed in the water container 102, and the other end passes through the tank body 1 and is suspended in the tank body 1. The water container 102 is a flat-bottomed centrifuge tube, and a hole is provided on the lid of the centrifuge tube for the cotton rope 101 to pass through. The cotton rope 101 can be replaced in time when it is dirty, so as to keep the drinking water clean and facilitate operation.

[0045] The manufacturing method of the fruit fly breeding device is as follows.

[0046] In this embodiment, the tank body 1 is a transparent plastic tank with a diameter of 10 cm and a height of 20 cm. After cutting out a ventilation hole 11 (about 50×40 mm) with an electric soldering iron, a 100-mesh ventilation net 4 is connected to the ventilation hole 11 with a glue gun. After cutting out an insect-removing buckle with a diameter of 4 cm with an electric soldering iron, the gauze cover 5 is connected to the tank body 1 with a hot-melt glue gun.

[0047] Then, a hole with a diameter of 7 cm is cut out at the bottom of the tank with an electric soldering iron, and a disposable plastic bowl cover is placed at the bottom of the tank to cover the hole. The plastic bowl cover is the bottom cover 3 in the egg collection box 7 of the present application.

[0048] Use an electric soldering iron punch to punch a hole in the middle of the can body 1, and install an elastic sealing ring to allow the adjusting rod 31 (a wooden stick with a diameter of 4 mm and a length of 20 mm) to smoothly move in and out obliquely, and use a hot melt glue gun to glue the adjusting rod 31 and connect it to the bottom cover 3 (disposable plastic bowl cover) of the bottle bottom.

[0049] A through hole 14 is punched at the lower part of the tank body 1 with an electric soldering iron punch, and a 60 ml ear cleaning bulb (ball diameter 49 mm, total length 105 mm) is inserted into the through hole 14 and further fixed with cotton.

[0050] An arc-shaped replacement opening 13 is punched on the upper part of the tank body 1 with an electric iron puncher, which is about 1 / 4 of the bowl cover. The disposable plastic bowl cover is divided into two halves, and the edge of the 1 / 4 bowl cover is cut off. A small part of the inner cover is cut off on the other side of the complete 1 / 4 bowl cover to leave an extended bowl cover edge. A small hole is punched on the periphery with an electric iron puncher and a traction belt is inserted to form a food tray 6. The food tray 6 is inserted into the arc-shaped replacement opening 13, and the edge of the food tray 6 is stuck with the tank body 1 at the arc-shaped replacement opening 13, and is further fixed on the outside with adhesive tape. The place where the middle of the adhesive tape fits the long hole is reversely pasted with adhesive tape or paper to facilitate tearing. When the food tray 6 is taken out, the arc-shaped replacement opening 13 can also be sealed with adhesive tape.

[0051] The water supply container is a 50ml flat-bottom centrifuge tube. Several 5mm holes are punched in the centrifuge tube cover and the middle of the transparent plastic tank body 1. A cotton rope 101 with a diameter of 5mm passes through the two holes. One end can draw water from the centrifuge tube and conduct it to the other end of the tank for fruit flies to drink.

[0052] The egg collecting box 7 is made as follows: the egg collecting box 7 is a disposable plastic bowl with a bottom of 6.5 cm, an upper part of 10 cm, and a height of 4.2 cm. The cover plate 8 is a lid matching the plastic bowl. Dozens of egg collecting holes 81 with a diameter of 2 mm are punched on the lid for fruit flies to lay eggs. When in use, open the lid and add egg attractants such as juice or melon.

[0053] According to the experimental needs, a certain number of adult insects are caught with a centrifuge tube and then placed in the tank through the insect release port. On the third day after the mating of the male and female, an egg collecting box 7 is placed at the bottom of the tank. The peak period of egg laying is from 16:00 to 18:30 in the afternoon. A wooden stick is slid to open the lower hole to allow the female insect to lay eggs on the cover 8 of the egg collecting box 7. When the time is up, the wooden stick is slid to lower the bowl cover to a lower position, and then the ear washing bulb is pressed to blow away the female insect. After the female insect leaves the lower part, the wooden stick is slid to cover the hole with the bowl cover, the egg luring box is taken out and washed with water, and then filtered with a 150-mesh gauze to count on black cardboard or observe the hatching rate.

[0054] When changing the feed, first put the feed in another food tray 6, then tear off the tape and pull out the food tray 6. If there are insects in the food tray 6, shake it first to drive away the insects, then take it out and replace it. After observing that the level of the centrifuge tube is lower than the cotton thread, add water or change the water in time. When the surface of the cotton thread becomes dirty, take it out, replace it and wash it.

[0055] In summary, the device occupies a small space, the device materials are easy to purchase, the cost is low, and it is convenient to collect fruit fly eggs, and the collection is very complete, which is conducive to improving the accuracy of the experiment. The device can be used to explore the egg-laying rate and egg-laying dynamics of fruit flies after different treatments, and biological observations such as lifespan and mating behavior can also be conveniently carried out, and it has a wide range of uses.
