Abstract
The utility model discloses a kind of Predatory Mites toxicity test device, comprise upper cover and base, cover on described and be provided with ventilative gauze, described base is hollow tubular and two open ends, sponge block is installed with in the cavity of described base, described sponge block is covered with holder worm gauze, and described upper cover internal diameter is greater than described base external diameter and makes upper cover to pack into base.Predatory Mites toxicity test installation cost of the present utility model is low, it is simple, easy to use to make, and can repeatedly use, and accurately and reliably, the test of the tiny insect such as suitable Predatory Mites uses measurement result especially.
Description
Technical field
The utility model relates to a kind of Predatory Mites toxicity test device, is applied to the determination of activity of agricultural chemicals indoor biological.
Background technology
Predatory Mites is one of good biological control natural enemy, the various pests (mite) such as tetranychid, greenhouse whitefly and thrips can be preyed on, there is safety, non-harmful advantage, be widely used in the control of the industrial crops insects such as fruit tree, tealeaves and vegetables abroad, the natural enemy product of Ye Shi China crop pests (mite) green prevention and control emphasis popularization simultaneously.But chemical prevention remains produces upper indispensable control of insect measure.Chemical pesticide is used the broad spectrum insecticide such as the contradiction unavoidably causing chemical prevention and biological control, particularly organophosphorus and chrysanthemum ester and is used Predatory Mites toxic action very big.
In order to coordinate the contradiction of chemical prevention and biological control, needing to select the chemical agent low to Predatory Mites toxicity, selecting the low chemical agent of toxicity to need the evaluation method of science.Meanwhile, the toxicity assessment method that Predatory Mites resistance needs science equally, all at seed selection Predatory Mites resistant strain of going into overdrive, is evaluated in current countries in the world.Predatory Mites because its body is little, strong, the back of own activity ability without reasons such as bristles, the toxicity test method of traditional tetranychids such as slide infusion process can not be used for reference.The method evaluated Predatory Mites toxicity is at present mainly blade and remains method; the method is by IOBC (The International Organization for BiologicalControl; international bio control tissue) adopted; also be classified as official comment's method by EPPO (European andMediterranean Plant Protection Organization, Europe and Mediterranean Plant Protection Organization) simultaneously.But the method Predatory Mites escapement ratio is very high, the result accuracy of gained is difficult to ensure.
Utility model content
For solving the problems of the technologies described above, the Predatory Mites toxicity test device that the utility model provides a kind of structure simple, easy to use.
The technical solution of the utility model is as follows: a kind of Predatory Mites toxicity test device, comprise upper cover and base, cover on described and be provided with ventilative gauze, described base is hollow tubular and two open ends, sponge block is installed with in the cavity of described base, described sponge block is covered with holder worm gauze, and described upper cover internal diameter is greater than described base external diameter and makes upper cover to pack into base.
The order number of the holder worm gauze that the ventilative gauze covered on described and sponge block are laid is more than or equal to 300 orders, prevents Predatory Mites from climbing out of device or bleeds in sponge from gauze.
Described upper cover and base interference fit, prevent Predatory Mites from climbing out of device.
Described upper cover madial wall and the outer wall frosted process of base near top, increase the leakproofness of device, prevent the Predatory Mites of small size from climbing out of device.
Described sponge block is on base bottom, and when preventing from detecting, sponge block directly contacts with the water in porcelain dish and causes the excessive accuracy affecting testing result of humidity in device.
The described area asking the area of worm gauze to be greater than sponge block makes to ask the edge of worm gauze can encase the edge of sponge block, prevents Predatory Mites from falling in sponge block from holder worm gauze the accuracy affecting testing result.
After described holder worm gauze encases sponge block edge, sponge block is fixed in base by glue, and the gap between sponge block and the inwall of base is filled up by glue, avoids Predatory Mites to fall in gap the accuracy affecting testing result.
The beneficial effects of the utility model are: Predatory Mites toxicity test installation cost of the present utility model is low, it is simple, easy to use to make, and can repeatedly use.On cover setting ventilative gauze make in device air circulation, ensure that the test environment residing for experimental insect has stable air humidity and oxygen, avoid experimental insect because of death by suffocation, the true effect for method for testing can be reflected really, make measurement result have more authenticity; The test being suitable for the tiny insect such as Predatory Mites especially uses.
Accompanying drawing explanation
Fig. 1 is Predatory Mites toxicity test apparatus structure schematic diagram used in the present invention.
Fig. 2 is the structural representation of upper cover in Fig. 1.
Fig. 3 is the structural representation of the utility model base.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As Fig. 1--the of the present utility model a kind of Predatory Mites toxicity test device shown in 3, be made up of upper cover 1 and base 2, upper cover 1 is provided with ventilative gauze 11, make the air circulation in device, ensure that the test environment residing for experimental insect has stable air humidity and oxygen, avoid experimental insect because of death by suffocation.
Base 2 is hollow tubular and two open ends, is installed with sponge block 22 in the cavity of base 2, and sponge block 22 is covered with holder worm gauze 21, and the area asking the area of worm gauze 21 to be greater than sponge block 22 makes to ask the edge of worm gauze 21 can encase the edge of sponge block 22.After encasing sponge block 22 edge with holder worm gauze 21, sponge block 22 is fixed in base 2 by glue, and the gap between the inwall of sponge block 22 and base 2 is filled up by glue.Can effectively prevent Predatory Mites from falling in sponge block from holder worm gauze or falling into the accuracy affecting testing result among the gap of sponge block and base inner wall like this.
Sponge block 22 is on base 2 bottom, and when preventing from detecting, sponge block directly contacts with the water in porcelain dish and causes the excessive accuracy affecting testing result of humidity in device.The order number of the holder worm gauze 21 that the ventilative gauze 11 on upper cover 1 and sponge block 22 are laid is 300 orders, prevents Predatory Mites from escaping from.
Upper cover 1 internal diameter is greater than described base 2 external diameter and makes upper cover 1 can pack into base 2, upper cover 1 and base 2 interference fit, and upper cover 1 madial wall and base 2 are near the outer wall frosted process on top, ensure that the leakproofness of device, prevent Predatory Mites from escaping from device and cause testing result invalid.
When carrying out Predatory Mites toxicity test, upper cover 1 is opened, on the holder worm gauze 21 gauze being placed with pesticide-treated Predatory Mites being put into base 2, then upper cover 1 is covered, whole device is placed on one to be filled on the porcelain dish of water, porcelain dish is moved in the growth cabinet of the temperature and humidity condition meeting experimental design, empirically the dead quantity of designing requirement timing observed and recorded Predatory Mites.
