Description
Technical field
The present invention relates to the agricultural cience and farming techniques field, specifically a kind of simple in structure, purifying screening plant of separating source, efficient land for growing field crops striatellus imago.
Background technology
Small brown rice planthopper belongs to the Homoptera Delphacidae, mainly is distributed in the wide geographic areas such as East Asia, Southeast Asia, Africa, Europe in the world, also extensively distributes in each main rice district of China, especially occurs more with the middle and lower reach of Yangtze River and North China.
The small brown rice planthopper host is very extensive, especially likes gramineous plants.Make beyond the region of objective existence except establishing in large scale such as paddy rice, wheat, barley, Chinese sorghum, corns, also comprise the multiple gramineous plantses such as moleplant seed, cicely, yard grass, English are white, amur foxtail, trip grass, wormwood, leaf of bamboo thatch, Paspalum distichum, annual bluegrass, Asiatic plantain, barnyard grass, convexutricle sedge herb, green foxtail, Huang Xucai, drinking water rice, reed.Small brown rice planthopper field host's popularity adds the diversity of crop rotation and planting patterns, so that the bridge that shift mutually in small brown rice planthopper population rice field, wheatland, sorghum field, weeds in field etc. increases, has increased the chance of surviving of population under the whole year various environment.Small brown rice planthopper is the temperate zone insect, has strong anti-adversity ability cold-resistant, anti-hunger, has increased the chance of surviving of population under various environmental conditions, causes its suitable scope of giving birth to very extensive, generally is distributed in the temperate climate band in East Asia, Southeast Asia, South Asia.Warm winter due to the global warming and temperature rising in spring were conducive to the safe overwintering of small brown rice planthopper population and rapidly procreation, so that the worm source radix of surviving the winter of small brown rice planthopper continues to increase in recent years.Control small brown rice planthopper major measure is cultural control at present, to use chemical agent as main, cause small brown rice planthopper that multiple insecticide has been produced pesticide resistance, thereby this single prophylactico-therapeutic measures is faced with formidable challenges, add the characteristic of migrating of small brown rice planthopper so that killing of small brown rice planthopper is very difficult.The popularization of japonica rice variety and plantation cause the paddy rice insect resistance capacity more fragile.So small brown rice planthopper is developed into the primary pest of Asia paddy rice gradually since the 1950's, especially in recent years small brown rice planthopper in many areas large-scale outbreak repeatedly, bring heavy losses to agricultural production.
Order at paddy growth in earlier stage, the harm of small brown rice planthopper is except the rice juice that absorbs water with adult, nymph thorn, cause the yellow leaf, withered of plant, cause sterile grain rate to rise, thousand kernel weight descends, and outside rice quality reduces, mainly is that it can pass malicious medium in paddy growth conduct in early stage, propagate stripe disease, black streaked dwarf virus of rice etc., cause greater loss to agricultural production.At late growth stage of rice, small brown rice planthopper generally lives in concentrated communities in rice clump middle and upper part with larger population density, and adult, nymph are all stung and inhale Culm of Rice and leaf juice.When insect density was large, the rice strain was withered and yellow because of a large amount of forfeitures of juice in the body.Small brown rice planthopper is discharged a large amount of honeydews at blade or tassel, can affect Rice Photosynthesis, also can grow mould, causes that the grain of rice goes rotten.The academy of agricultural sciences, Jiangsu measure to find, small brown rice planthopper endangers serious plant than light 8.92 grams of normal plant, and plant height reduces 33cm, and spike length and number of grain per ear reduce respectively 5.49cm and 28.5, and half real rate and unreal rate increase respectively 36.3% and 3.20%, and the underproduction reaches 41.5%.Small brown rice planthopper is typical sucking pest, except direct harm causes damage, can also propagate the multiple diseases such as oryza virus 3, rice black-streaked dwarf virus and MRDV poison.Small brown rice planthopper is developed into the primary pest of Asia paddy rice gradually since the 1950's, brings heavy losses to agricultural production.And the oryza virus 3 that the small brown rice planthopper amboceptor is propagated and rice black-streaked dwarf virus become two large Major Diseases of harm middle and lower reach of Yangtze River rice workspace.Stripe disease starts at China's southern Jiangsu Province in 1963.After this national many places all happen occasionally, and many areas are popular causes disaster.Should disease become great fulminant disease in provinces such as Jiangsu, Henan at present, to be that a kind of on current China paddy rice distributes wide, it is heavy to occur, large important virus disease causes harm.According to incompletely statistics, the onset area that the whole nation in recent years should disease has reached 2,700,000 hm
2Above, the sick cave of general field rate 5%～30%, grave illness field 50%～60%, serious field reaches more than 80%, can cause paddy rice to drop in production over a large area, even total crop failure, brings heavy economic losses to the peasant.Rice black-streaked dwarf virus also is a kind of virus disease of being propagated by small brown rice planthopper, infects paddy rice and causes black streaked dwarf virus of rice, and paddy rice is in a single day susceptible just without results.In recent years, various along with variation, the agricultural ecological of cropping system and planting type, winter climate warms and the spread of susceptible variety, black streaked dwarf virus of rice in Jiangsu, Zhejiang, Hunan etc. economize large-scale outbreak, cause serious harm to agricultural production.Seriously occur according to Jiangsu Province's plant protection unit statistics cut-off disease ground such as Yancheng, Lianyun Harbour, Taizhou, Huaian, Yangzhou and Xuzhou coastal in this province, that go to river in reaching in the Huaibei in 2007, the area of Occurrence reaches 30.8 ten thousand mu then, the generation area of black streaked dwarf virus of rice in 2008 then surpasses 4,000,000 mu, and the situation of disease eruption and prevalence is very severe.
In the face of virus disease with sudden and explosive characteristics, screening that pest-resistant disease-resistant variety is applied to produce is the most direct effective method.Because the resistance to insects evaluation of paddy rice small brown rice planthopper and stripe disease, black streak dwarf Disease Resistance Identification need a large amount of striatellus imagos, and small brown rice planthopper artificial feeding difficulty is large at present, feeding cost is higher.Annual twice great outburst small brown rice planthopper in period very easily grasps and small brown rice planthopper is in the land for growing field crops, is the most direct easy most economical mode that obtains the required a large amount of striatellus imagos of experiment so grasp from the land for growing field crops at the small brown rice planthopper Onset.
Yet because the land for growing field crops ecosystem various insects of growing, can mix from the small brown rice planthopper colony of land for growing field crops crawl has a large amount of impurity and assorted worm, comprises that the various insects such as natural enemy ladybug, spider of small brown rice planthopper mix therebetween; And the small brown rice planthopper worm age of land for growing field crops crawl and irregular, each, nymph and adult mixed in age; In addition, external force is to the injury of small brown rice planthopper during owing to crawl, and many meetings are died.If directly use, the irregular meeting in assorted worm, the dead worm of small brown rice planthopper and small brown rice planthopper worm age has a strong impact on the reliability of experimental result.So in the urgent need to designing a kind of small brown rice planthopper purifying screening plant, can from the small brown rice planthopper population of land for growing field crops crawl, screen small brown rice planthopper by purifying, get rid of the interference of impurity elimination worm, and striatellus imago and nymph can be made a distinction, select pure striatellus imago to be used for experiment, guarantee reliability and the science of experimental result.This application of installation is used for Resource exploitation screening, breed breeding and the genetic development research of small brown rice planthopper host crop in the Resistance Identifications such as the disease resistance test of crop small brown rice planthopper resistance to insects, small brown rice planthopper amboceptor virus disease.
