Description

Miniature cage device suitable for small insect is experimental

Technical Field

The invention belongs to the field of biology, and relates to a miniature cage device suitable for small insect tests.

Background

Bemisia tabaci (Fr.) Kuntze Bemisia tabaci(Gennadius) belongs to Hemiptera, Aleyrodidae and Stenorrhyncha, and is a worldwide important agricultural pest. Originally in tropical and subtropical regions, with the trade round in the world since the 80 s of the 20 th century, bemisia tabaci quickly spreads by virtue of nursery stocks of flowers and other economic crops, is widely spread around the world and outbreaks to cause disasters, and becomes a worldwide super agricultural pest. The bemisia tabaci induces sooty mould by directly puncturing plant juice and secreting honeydew, weakens the photosynthesis of plants and further influences the growth and development of the plants. Meanwhile, the bemisia tabaci can also cause indirect harm to crops by spreading plant virus diseases, so that the economic loss caused by the indirect harm is more serious.

The bemisia tabaci is tiny in size, adults are good at flying, and when indoor biological and ecological tests of the bemisia tabaci are carried out, the adults are often required to be fixed, for example, in similar test researches such as oviposition mating of the bemisia tabaci, a micro-insect cage or a micro-cage device is required to be used, the adult bemisia tabaci good at flying is fixed within a certain range to lay eggs, and the adults are moved away after the adults lay eggs; or fixed in a certain range for observing mating behavior; in the process of researching the parasitic test of the parasitic wasps on the bemisia tabaci, the originally hatched parasitic wasps are fixed on the leaves with the bemisia tabaci nymphs by using the miniature cages, so that the parasitic rate and the fatality rate of the parasitic wasps on the bemisia tabaci nymphs at a certain proportion are researched. At present, various laboratories can use miniature cages with different specifications, but the following problems often occur when the traditional miniature cages are used for small insect tests: firstly, the test insects are easy to escape in the process of transferring to a miniature cage or replacing a parasitic part, so that the number of experimental samples is obviously reduced, the accuracy of research results is influenced, or the experiment cannot be continued due to great reduction. Second, traditional miniature cage is because including the metal clip, self weight is overweight, when adopting comparatively young tender plant growth initial stage to test, fixes such miniature cage and presses disconnected branch and leaf very easily, influences the plant normal growth. Thirdly, the leaves of the plant with the miniature cage fixed partially can also generate the phenomenon of yellowing and discoloration, and the biological observation of the test insects is directly influenced. Therefore, how to provide a lightweight, convenient and effective micro-insect cage for preventing the escape of the test insects, which is suitable for a device for researching population purification, oviposition test, parasitism and the like of the micro-insects, becomes a technical problem to be solved urgently by scientific research technicians in the field.

Disclosure of Invention

To the above problem, the utility model designs a be suitable for miniature cage test device of small-size pest scientific research, the device light, convenient, can effectively prevent the examination worm escape, be fit for being used for research such as small insect population purification, oviposition experiment and parasitism, solved the technological problem who awaits a urgent solution for scientific research technical staff in this field.

The utility model provides a technical scheme is: a miniature cage device suitable for small insect test mainly comprises six components: the cage body, gauze, tail clamp, connect worm device, foam-rubber cushion, get the worm ware, the cage body includes upper and lower two cups, its shape of cup is the round platform shape, and the cup is equipped with big, osculum, and the macrostoma is the clamping opening, and the osculum is equipped with the gauze, the foam-rubber cushion is established between the macrostoma of two cups, and two cups pass through the tail and press from both sides abundant clamping of cage body is close osculum one side cage body and is equipped with and connects the worm device, get the transparent ultra-thin plastic hose that the worm ware can be crooked wantonly for the compliance is strong.

In the miniature cage device, the gauze is a 200-mesh gauze and is used for preventing insects from escaping, ventilating and preventing water vapor from being in the cage.

The miniature cage device, the insect receiving device is: an insect receiving small opening is formed in the side, close to the small opening, of the cage body, the size of the opening of the insect receiving small opening is determined according to the size of the insect fetching device, and an anti-escape device is assembled in the insect receiving small opening; the anti-escape device is a section of latex tube, when the insect is connected, the latex tube can be directly inserted into the insect, and after the insect is connected, the latex tube utilizes the self gravity to seal the insect connecting opening so as to achieve the purpose of preventing the insect from escaping.

Furthermore, in the miniature cage device, the cage body is preferably made of light transparent plastic; the spongy cushion is a foamed ultrathin spongy cushion or an ultrathin filtering spongy cushion; the insect fetching device is suitable for fetching a single head or a single pair of insects.

The utility model discloses following beneficial technological effect has:

the utility model discloses miniature cage device material is frivolous, add and connect insect population, transparent be convenient for carry on the small-size insect lay eggs, biological characteristics such as mating observe, also reduced the escape rate of examination worm. For example, when the original traditional micro-insect cage is used for scientific experiments on insects such as single-head bemisia tabaci gennadius and encarsia formosa, the escape rate in the transfer process reaches 40%, and after the device is adopted, due to the fact that the specific insect receiving part is additionally arranged, when the single-head bemisia tabaci gennadius or encarsia formosa is transferred, the escape rate of the tested insects can be reduced to be within 10%, and the persistence of a test sample and the accuracy of a result are effectively guaranteed; when the light miniature cage in the device is clamped on plant leaves, the damage to the branches and leaves of young plants of the plants is obviously reduced, and the drop of the branches and leaves and even the breakage of the branches and leaves are obviously reduced (the falling rate of the leaves is zero in most tests); and simultaneously, use the utility model discloses plant of miniature cage device can be better carry out photosynthesis, for experimental continuation provide basis and experimental material guarantee.
