The main drafters of this standard .Miao Wenbin, Chen Xiang, Chen Jun water, Hu Xunjun, Wang Haiting, Liu Chunxin, Li Lifang, Jiang Wei, Tao Haihua, Chen Huiming, Zhang Jing, Guo Jian.IntroductionThis standard is mainly used to assess the impact of chemicals on the reproduction ability of soil-stinking Reynards. The standard in the existing test procedures Based on the development. Folsomiacandida, asexual reproduction and Folsomiafimetaria, breeder reproduction, are common Varieties can be obtained through farming or through market channels. When these two species of insects do not meet the assessment requirements for some special habitats, too You can use any other species that meet the test's validity. From an ecological point of view, soil-living hopper is a more appropriate ecotoxicological test varieties. Coccinella is a kind of hexapod Arthropods, with a thin layer of exoskeleton that is highly permeable to water and air, have different routes of exposure compared to earthworms and earthworms level. In most terrestrial ecosystems, population density of hoppers living in soil and deciduous layers is generally 105 per square meter. The typical mature individuals are 0.5mm ~ 5mm, which contribute very little to soil biomass and soil respiration, only 1% ~ 5%. So the soil The more important role of the Collembola is to serve as a potential regulator of the food chain as a food source for soil microbes and small animals By. The soil-stinking hopper itself can be widely distributed within a wide range of species, including ticks, centipedes, spiders, pests and flies Raw and epigenetic invertebrates prey on. Soil pinworm helps to disrupt acidic soils. And because earthworms and millipedes usually do not exist In acid soils, the Collembola has therefore become the most important invertebrate in such environments beyond wireworms. F. fimetaria hoppers are distributed throughout the world, from sand to loam, from the fine humus to coarse humus and other typical soil Widely present in the soil, it is a colorless, colorless eye-catcher that is found in agricultural soils throughout Europe. There are omnivorous habits, Its food includes fungal mycelium, bacteria, protozoa and debris and so on. F. fimetaria occurs through contact with pathogenic fungi that infect plants Interacting and affecting mycorrhizal fungi, which is the same as F.candida. Like most tortoise species, F. fime- Taria hopper sexual reproduction, requires the existence of male fertilized eggs. F.candida is also distributed throughout the world. Although not commonly found in common soils, such hoppers are found in humus-rich soils There is a lot of soil. It is without eye pigment, wishbone (bomb) developed, always in an active state of wandering, once disturbed, it will quickly Move and beat. The mechanism of F.candida's ecological impact is similar to that of F. fimetaria but its habitat is dominated by higher organic matter Soil. F.candida is asexual reproduction. The probability of a male is less than one in a thousand. Reproductive testing of insects in soil chemicals1 ScopeThis standard specifies the terms and definitions of reproductive tests of insects (hoppers) in the soil chemicals, test principles, test methods and procedures Steps, data and reports. This standard applies to assess the effect of water-soluble or water-insoluble substances on the reproductive effects of soil enemies of tail-tailed insects (hoppers). This standard does not apply to volatile substances, that is, Henry constant or gas/water partition coefficient greater than 1, or at 25 ℃ when the vapor pressure exceeds 0.0133Pa Material.2 Normative referencesThe following documents for the application of this document is essential.
