| The thrips are collectively referred to as insects. Larvae are white, yellow, or orange, adult yellow, brown or black; feeding plant juice or fungi. Thripsae Thripaeae Thysooptera Thuleoidea, known to the world 276 genera of more than 2000 species, including the needle thymus subfamily Panchaetothripinae, stick thrips subfamily Dendrothripinae, serpentine sericulture Sericothripinae and thrips Asia Thripinae 4 subfamilies The The insects are widely distributed in the world, food complex, mainly phytophagous, bacillus and predatory, of which phytophagia accounted for more than half, is one of the important economic pests. First, the product principle: Sexual attractant trapping pest technology is the country in recent years advocated by the green control technology, the principle is through the synthesis of females after sexual maturity released some called pheromone chemical composition, to attract the same species to seek mating male, Trapping in the trap, so that the loss of mating opportunities for females, can not effectively reproduce the offspring, reduce the number of offspring population to achieve the purpose of prevention and treatment. Second, the product features: High selectivity, each insect needs a unique formula and concentration, with a high degree of specificity, the other insect species is not tempting. No drug resistance. Environmental protection, no pollution, and other control technology 100% compatibility. Significantly improve the quality of agricultural products. The following are the same as the " Third, the application strategy: In the early stages of pests, when the population density is relatively low, it is used (that is, when the pest is winter). The treatment area should be greater than the range of pests to reduce the invasion of mature females and reduce the control effect. And more combined with other prevention and treatment methods, play a comprehensive prevention and control effect. The following are the same as the " Fourth, use: According to the occurrence of field pests set up special-purpose lureurs and traps. Used in vegetables, the general per 667 square meters set up a dedicated trap, each trap placed within the lurex 1; available paper viscose or basin for traps (to maintain the height of the water, so that distance from the lure 1 cm). Dedicated traps hanging at the bottom of the crop from the top 10 cm to 30 cm is appropriate, depending on the crop growth habits. Sexual attractant applied to the fruit trees, requiring the height of the suspension to lure from the ground about 1.5 meters is appropriate, every 667 square meters two or three lure. The following are the same as the " Fifth, save the method: The attractant is volatile and needs to be stored in a lower temperature refrigerator (-15 ° C to 5 ° C). Keep the place away from the high temperature environment, the lure should avoid exposure. Use sealed bags before opening. Capillary type only when used to cut the seal. The following are the same as the " Sixth, note: Due to the high sensitivity of sexual attractants, the installation of different species of pests, need to wash their hands, so as not to contaminate. Under normal circumstances 4-6 weeks to replace a lure. The following are the same as the " This product is best used with the supporting tractor or yellow board. Seven, the recommended use: Traps 1-2 sets / mu. Hanging to the top 20cm above the crop, in principle, the outer dense, dilute the middle. According to the field of insects may be appropriate to deploy the number of hanging. Eight, lure duration: Domestic type about 4-6 weeks, imports from about 2 to 3 months, the duration of different regions slightly different. |
