Description
Technical field
The utility model relates to a kind of pesticide to branch class sucking pest Toxicity Determination new equipment, is applied to the indoor biological activity determination of agricultural chemicals, also can be applicable to carrying at a distance of pierce-suck type live body insect.
Background technology
Usually need in the novel pesticide development process to carry out agricultural chemicals to the biological activity determination of insect, in the scientific research process relevant with the pesticide research field such as pest resistance to insecticide monitoring, all relate to the work of agricultural chemicals Toxicity Determination, the assay method of " People's Republic of China's agricultural industry criteria " relevant agricultural chemicals (pesticide) indoor bioassay test rule regulation has drop method at present, press from both sides malicious blade method, fumigating system, the blade immersion method, dip method, wherein the insect of sucking mouth parts is mainly adopted drop method, immersion method and dip method are measured continuously, but, these criterions have just been stipulated experimental insect, the standard of experimental plant organization material and experimental pharmacy relevant treatment, the plant tissue material nutrition supply that how to guarantee after experiment is handled to exsomatize is normally got the food aspect and is not then had clear and definite standard to guarantee experimental insect, particularly carry out pesticide to branch class sucking pest Toxicity Determination in, isolated experiment plant tissue material is preserved moisture, nutrition supply and the test space environment that provides experimental insect to suit activity are Success in Experiment and the key link that obtains accurate data.At present, in the scientific experiment process of relevant agricultural chemicals toxicity test, all be to adopt filter paper after the experimental plant organization material chemicals treatment, absorbent cotton, water-absorbing materials such as flower mud are implemented simple and easy moist keeping measures, place plastic bottle or double dish that experimental insect is carried out simple and easy breeding observing then, but all there is obvious defects in these methods at present: at first material which can retain moisture does not have and the tight immovable combination of test container, observe in experiment and often to cause material which can retain moisture to move in the mobile test container processes and cause the plant tissue material to come off from material which can retain moisture, very easily cause experimental insect to be extruded and dead; And adsorbed nutrition and the moisture of these material which can retain moisture is limited, can only play the short time effect, can't continue to satisfy preserving moisture and the nutrition supply effect of isolated experiment plant tissue material the long period, often cause stripped plant branch tissue shortage nutrition and moisture to cause plant tissue withered easily, cause experimental insect to lack food and death; In addition, currently used test container can't provide ventilated clog-free activity space environment for experimental insect, causes the too high oxygen that lacks again of humidity in the test container, causes the phenomenon of a large amount of deaths by suffocation of experimental insect; Thereby cause pesticide Toxicity Determination experimental result inaccurate even cause the failure of an experiment, great amount of manpower and material resources and financial resources have been wasted, in addition, the source of nutrition and the material which can retain moisture that also have the agar layer utilized to cultivate as the plant leaf blade short time of exsomatizing, but the operating process of this method is comparatively numerous tired, also can't the activity of real simulation insect field and the virtual condition of getting food.Above-mentioned these problems, what show in branch class sucking pest Toxicity Determination experimentation is particularly evident, is badly in need of a kind ofly overcoming the new equipment of above-mentioned defective to satisfy pesticide to branch class sucking pest Toxicity Determination research work.In addition, in pest resistance to insecticide study on monitoring process, the insect that needs to gather zones of different carries out Toxicity Determination, this relates to the problem that experimental insect carries at a distance, if and experimental insect is carrying shortage food and the ventilated phenomenon that also can cause its energy decline or mass mortality in the process at a distance, certainly will cause the experimental insect that carries at a distance can not satisfy the laboratory experiment requirement, thus cause the experiment can't normally carry out or experimental result inaccurate.Therefore, are research purposes of the present utility model at the problems referred to above.
The utility model content
The purpose of this utility model is to provide a kind of pesticide to branch class sucking pest Toxicity Determination device, helping to solve present pesticide is extruded easily to the experimental insect that branch class sucking pest Toxicity Determination exists, the plant branch tissue that exsomatizes lacks nutrition and the moisture supply causes dry dehydration even withered, thereby experimental insect lacks the problem that ventilated clog-free activity space environment causes the inaccurate or the failure of an experiment of experimental result, this device utility model has solved that experimental insect is extruded easily in the pesticide Toxicity Determination, exsomatizing, plant branch tissue can not effectively be fixed and continual and steady nutrition and moisture is supplied with, the space environment condition of ventilated accessible activity is provided for experimental insect, the virtual condition of having simulated the activity of insect field comparatively truly and having got food has improved accuracy and the reliability of pesticide to branch class sucking pest Toxicity Determination result.
The technical solution of the utility model is:
A kind of pesticide is to branch class sucking pest Toxicity Determination device, comprise living cover, bottom and the living cover square of surveying surveyed that two ends are run through, its feature exists: the described bottom of surveying cover of giving birth to is connected with bottom, the described top of surveying cover of giving birth to is connected with the living cover square of surveying, be positioned at living the survey on the bottom middle part of covering and be installed with column container, be filled with a water absorptivity column in order to fixing and the branch of preserving moisture in the described column container.
Wherein, described giving birth on the sidewall of surveying cover offers the gauze window.
The described middle part of surveying the cover square of giving birth to offers the gauze window.
