Descriptions: 4 choice insect olfactometer is an instrument applied in studying the behavior of insects with strong ability of activity. Insets communicate with the host plant via odor about the information of spawning, feeding and other activities, so odor is very important for insects. The insects’ olfactory behavior could reveal the chemical relationship between pest and host plant, and could also provide a new way to the prediction, monitoring and prevention of pests. Qt-wii01 4 choice insect olfactometer principles: the air and mixed gas flow throw the four odor channels into the activity room, and the vacuum pump will extract the mixed air through a vent hole. When the experiment starts, insect will be placed in the center of the activity room, and the vacuum pump begins to work after closing the activity room. The air and mixed air will flow into the room under constant pressure, the tested insect will react differently to different odors, if the insect is sensitive to one odor, it will creep to the odor source. Testing process: before testing, place tested insects with the same physiological indices in the center of the activity room, after opening the vacuum pump, the insect will meet the odor air, and creep according to the odor density, at this time, record the quantity of creeping insects. applications: study on the relationships between insects and plant chemical substances. Study on chemical ecology. Study on insects’ behavior. Monitoring insects’ behavior supported with camera system. specifications: flowmeter: 0.1-1lmin for adjusting the air flow speed. Balance bottle: 100 ml, for containing the distilled water, and adjusting the air moisture. Odor bottle: 100 ml，for containing the volatile oil and solvent.

Product description：qt-led1218 plant fill light lamp can help the formation of anthocyanin and restrain the elongation of branches, it can also make the plant stems and leaves grow better and accelerate plant growth. By the regulation of stomatal opening, it can promote oxygen demand, which helps plant gain more nutrients, and further promote the growth of root and the growth of leaves in the early stage of germination. The plant fill light lamp can also promote the growth of plants as a whole, and particularly in flowering period and fruiting period, it can make plant bloom and bear fruit 20-30 days earlier than usual, and it can make vegetable yield increase by 20% ~ 30%. It can also increase the vividness of flowers, increase the storage period of flowers, vegetables and fruits by 5 ~ 10 days, and reduce plant diseases, insect pests and malformed fruit. qt-led1218 plant fill light lamp qt-led1218 plant fill light lamp features: based on the traditional red and blue monochromatic led plants fill light, pink color led light is available; the light is completely designed in accordance with the standards of fluorescent lamp, with good interchangeability and compatibility; light size, shape, power and input power supply can be customized according to users’ requirements; good quality, account for a large share in the market of led plant fill light lamp; using silica gel patch led chips, good material and advanced technology, the lamp has less light degradation and longer service life.; the ratio of red to blue light can be adjusted easily without affecting the manufacturing process of lamps and structure change; power supply can be customized as built-in type, external type, no power type. External power supply can extend the lifespan of the led lamps. However, no power supply type is the best, which is no longer a constraint of the led light;
