The utility model relates to ecological technique field, particularly relates to a kind of insect experimental rig.

Background technology

Insect pest not only endangers field ecosystem, and the Ecological environment for other also causes serious threat, and in order to provide knowledge and technology to the prevention and control of insect pest, scholars are devoted to study this always.

At present, to the investigation of insect pest kind under wild environment, there is employing five point sampling for the more uniform situation of investigation sample individuality distribution, have and adopt branch counting method for investigating the insect of being not good at flying, employing method of shaking is had to investigate seemingly-dead property insect, have and adopt net to sweep the stronger insect of method investigative action ability, also have and adopt search method to collect individual larger insect; General insect of being collected by inquiry agency is taken back indoor and makes sample, then carries out the qualification of quantity, kind and Harm according to sample; The weak point of these investigation methods is above, insect is made into sample, identify that its kind relies on human eye identification completely, as there is larva or other uncommon insects in fruit insect sample, sense only based on surveyor is often difficult to clear and definite kind, and sample is owing to leaving plant environment and making sample, the research movable to the taking food of insect itself, breeding etc. is made to cause obstruction.

The loss appraisal that prior art is brought for large regions insect pest mainly relies on remote sensing technology, utilizes remote sensing technology observing and predicting aspects such as pest occurring area, plague grade and frequencies.The deficiency of remote sensing technology is the qualitative detection can only carrying out macroscopic view to insect pest, lacks the quantitative analysis of microcosmic, provides not enough to insect pest prevention and control information needed.

At present, the method that Traditional measurements insect pest is lost the ecosystem, also comprise and adopt index for control to estimate as population density, but due to the degree that annual insect pest generating capacity may propose higher than index for control, therefore can underestimate as the method for density calculation the loss that pest causes by index for control in some degree.

Therefore, for above deficiency, need to provide a kind of novel insect experimental rig.
