Description

A kind of crop insect educates case altogether
Technical field
The present invention relates to a kind of agricultural, biological scientific research field, refer in particular to a kind ofly in order to extensive raising crop plant-feed insect and can be used as the resistance to insects of crop and insect amboceptor bacteriosis viral disease disease resistance is identified the device of platform, specifically a kind ofly be applicable to that the crop insect of raising the crop insect simultaneously and cultivating crop educates case altogether.
Background technology
Plant-feed insect is of a great variety, population quantity is huge, bring huge harm to agricultural production, food crop makes that its yellow leaf is withered to many plant-feed insects except directly getting, output descends, quality reduces, can also be as the vector of various crop virus disease, bacteriosis, only insect-borne crop virosis evil annual to crop production cause with a toll of tens dollars.
The caste of harm agricultural production is various, indulges as the thrips on the Rice Production, leafhopper, small brown rice planthopper, brown planthopper, white-backed planthopper, rice etc.; Wheat aphid on the Wheat Production, leafhopper, suction slurry worm, penthaleus major duges, small brown rice planthopper etc.; Corn borer on the Maize Production, prodenia litura, small brown rice planthopper etc.; Diamond-back moth on vegetables produce, beet armyworm, trialeurodes vaporariorum, thrips, liriomyza bryoniae etc..The bacteriosis of being propagated by the insect amboceptor on the crop production, the kind of virus disease are also very various, as black streaked dwarf virus of rice, the stripe virus disease that has small brown rice planthopper to propagate on the Rice Production, rice grass shape bushy stunt, the tingia that brown planthopper is propagated stunt disease and rice sheath blight disease, culm rot, the southern rice black-streaked dwarf disease that white-backed planthopper is propagated, rice dwarf virus disease, yellow dwarf and verticillium wilt etc. that leafhopper is propagated; Little (greatly) wheat produces and goes up the wheat rosette stunt that small brown rice planthopper is propagated, little (greatly) wheat yellow dwarf that wheat aphid is propagated, the wheat red stunt that the husky leafhopper of bar is propagated, the wheat streak mosaic that the wheat koji leafhopper is propagated etc., the MRDV that small brown rice planthopper is propagated on the Maize Production, corn short mosaic disease of aphis propagation etc.
Just because of the huge harm that plant-feed insect for a long time brings to crop production, crop and insect are studied mutually so also are research emphasis in agricultural, the biological scientific research field.On the one hand, the physiological Study of planting property of crop herbivore insect, the susceptibility of insect insecticide and scientific researches such as resistance detection, indoor resistance risk assessment are to producing the actual important directive significance that has, and these researchs all need be raised a large amount of insects; On the other hand, the researchs such as resistance detection that the research of insect amboceptor crop disease, crop are directly got food and insect amboceptor crop pest to insect also need a kind of long-time common platform of cultivating crop and insect that is fit to.
At natural world, insect just lives in the very long period of history with parasitic crop, dyadic interaction, influence each other, regulate restriction mutually, coevolution, and the land for growing field crops ecosystem is exactly the good platform of doing mutually of insect and parasitic crop, and the artificial culture of crop and insect is to realize by the simulation to the land for growing field crops ecosystem invariably.And influencing each other between insect and crop restricted by the polytropy of natural environment, ecotope, so overcome the polytropy of the land for growing field crops ecosystem, setting up stable ecotope just becomes essential that crop and insect do to study mutually.
What at present simulating nature circle ecotope was cultivated crop has climatic cabinate, a climatic chamber etc.Yet, climatic cabinate and climatic chamber are done research mutually insect and crop still the inconvenience part,, insect transfer operation inconvenience big as the frequent moisturizing of need consumption power, easily cause problem such as insect escape, in addition, climatic cabinate and the climatic chamber cost is too high, volume exclusion is big is difficult to be applied to large-scale insect and tests mutually.Therefore, setting up a kind of crop insect simple and convenient, low-cost, applied widely makes platform mutually research is had great practical value.
Small brown rice planthopper belongs to the Homoptera Delphacidae, overflows in the middle and lower reach of Yangtze River and North China at present.The host is gramineous plantses such as various lawns dogstail and water paddy and wheat class, corn, barnyard grass, divided by adult, nymph thorn inhale cause harm outside, can also propagate black streaked dwarf virus of rice, stripe virus disease, wheat rosette stunt, MRDV and the striped multiple virus diseases such as disease of stunting, agricultural is had huge harm.
Present many scientific research institutions have all set up small brown rice planthopper artificial feeding system, raise methods such as (single seedling single tube method for breeding) as solarium's plantation rice seedling method for breeding, the potted plant rice seedling method for breeding of greenhouse sarong, indoor single worm.But these methods have shortcoming separately, and indoor a large amount of propagating and breeding technologies do not obtain further perfect always.There are paddy growth cycle length in small brown rice planthopper solarium plantation rice seedling method for breeding and the potted plant rice seedling method for breeding of greenhouse sarong, shift problems such as worm operating difficulties and worm escape; Indoor single worm is raised rule and exists operation loaded down with trivial details, is difficult to problems such as extensive raising; Simultaneously the rice fulgorid rice shoot is raised in cages and indoor single worm raising all exists and is difficult to obtain a large amount of worm consistent examination worm and excessive shortcoming of human input in age.The more employing of laboratory rearing small brown rice planthopper at present be indoor beaker method for breeding, this method is to carry out at the receptacle that constant temperature air conditioning is installed, which floor brandreth of indoor placement, every layer of top is equipped with daylight double (before the fluorescent lamp circuit time switch being installed), be placed with the beaker of plantation sense worm kind paddy rice on the shelf, small brown rice planthopper is just raised on the rice seedling of growing in beaker, and the beaker mouth wraps up guaranteeing to breathe freely with white gauze.Cause in the beaker rice growth poor owing to blocking of rice seedling top white gauze causes the not enough and reason such as can't apply fertilizer of illumination, and have that the number of animals raised is little, manpower is wasteful, support the inefficient problem of worm.
With small brown rice planthopper serious generation in Yangze river and Huai river rice district in recent years as the paddy rice virus disease that passes malicious media, cause the underproduction significantly.Black streaked dwarf virus of rice in the small brown rice planthopper amboceptor paddy rice virus disease and stripe virus disease become the main rice disease in rice district, the present middle and lower reach of Yangtze River.Resistant gene is excavated, and utilizes the molecular marker assisted selection breeding technique to cultivate the disease resisting rice kind, is considered to control the most cost-effective method of rice disease.The excavation of resistance germ plasm resource resistant gene is the prerequisite of disease resistance rice genetic breeding, and the rice germplasm resource is carried out the problem that variety resistance is identified becomes primary solution.The rice varieties disease resistance of paddy rice small brown rice planthopper amboceptor virus disease is identified the interference that has paddy rice resistance to insects antagonism characteristic of disease under the ecosystem of land for growing field crops, influencing each other and restricted by the polytropy of natural environment, ecotope between small brown rice planthopper and paddy rice simultaneously, so overcome the polytropy of the land for growing field crops ecosystem and the interference of paddy rice resistance to insects, setting up stable ecotope just becomes essential that paddy rice and small brown rice planthopper do to study mutually.The black streaked dwarf virus of rice disease resistance identify to be adopts small brown rice planthopper nymph under the greenhouse to raise the poison back and moves into to strengthen on the rice varieties rice shoot to be identified and pass that poison realizes, portion is withered greatly when yet beaker commonly used is cultivated the rice seedling paddy growth to tri-leaf period, can't further pass poison, identify that as the black streaked dwarf virus of rice disease resistance platform becomes urgent problem so set up the artificial ecoenvironment of constant suitable paddy rice and the long-time common growth of small brown rice planthopper.
