Description
Technical field
The invention belongs to inada's disease insect pest prevention and control field, be specifically related to a kind of oophagous trichogrammae rice field method for releasing.
Background technology
Trichogramma spp is in a kind of parasitic insect of Hymenoptera Trichogramma spp, owing to it is single, compound eye all is red, therefore be called oophagous trichogrammae.The one-tenth polypide of oophagous trichogrammae is long to only have 0.3-1.0mm, is generally yellow or yellowish-brown, and most of queen bees and drone are by carrying out the breeding that the offspring is finished in the mating activity in pin main body.The research of oophagous trichogrammae starts from the thirties in 20th century, and the later stage sixties enters high-speed development period, and 1977, Nagaratti and Nagaraja recorded in the world 36 kinds of honeybees, and nineteen ninety is to annotate studies show that according to woods, and may there be more than 90 kind of oophagous trichogrammae in China.The application of oophagous trichogrammae also starts from the sixties ,-nineteen fifty-five in 1954 Guangxi successively carried out oophagous trichogrammae control sugarcane moth borer and corn borer; Insects such as using oophagous trichogrammae control striped rice borer, lima bean pod borer and sugarcane moth borer is carried out in a year Hunan, nineteen fifty-five-1956; Subsequently, other provinces and cities also begin to promote research and the application of this technology.The seventies and the eighties, China large-area applications is promoted and is reached a climax, and northeastward etc. ground utilizes egg of oak silkworm as middle host egg, makes to educate honeybee and control the application that worm is operated in the production practices and develop rapidly; Some places, Guangdong utilize rice moth (Corcyra cepphalonica) ovum breeding oophagous trichogrammae, have play a part positive to solving host's deficiency.Nowadays, the yellow oophagous trichogrammae of artificial host egg's amount reproduction snout moth's larva is stepped into by technological process and quality standard and carries out the new stage that batch production is produced, but the oophagous trichogrammae method for releasing is respectively different to some extent.
Summary of the invention
The technical problem to be solved in the present invention be, insect low for oophagous trichogrammae field breeding quantity explosive cause harm and honeybee body vitality a little less than etc. problem, and provide a kind of practicality concrete oophagous trichogrammae field method for releasing, with the insects such as striped rice borer, rice leaf roller, rice green caterpillar, rice plant skipper and armyworm in effective control rice field, reduce the radix of snout moth's larva in the rice field, alleviate to chemical agent dependence.
In order to achieve the above object, technical scheme provided by the invention is:
A kind of oophagous trichogrammae rice field method for releasing comprises the steps:
(1) low amount breeding discharges: before the prevention target insect, discharge a small amount of oophagous trichogrammae and oophagous trichogrammae host egg; Best release period is in rice plant of tillering stage, trichogramma releases when the total moth amount of the lepidoptera pest that comprises striped rice borer, rice leaf roller, rice green caterpillar, rice plant skipper and armyworm reaches 100-200 every mu or every mu and can parasitic insect ovum total amount reaches 10000-20000, burst size is 5000-10000 every mu;
(2) dynamically control evil discharges: dynamically carry out target pest control for the generation of insect, according to target pest master evil long-term emergence period in generation and insect development progress, the moth emergence period of tentative prediction target pest, observe insect moth appearance and field moth emergence size situation at the moth appearance initial stage, insect moth appearance beginning Sheng phase trichogramma releases, burst size=moth amount * 30-field egg parasitoid amount * 70%; Wherein, described moth amount refers to behind the insect moth appearance quantity of moth in the rice field, and described field egg parasitoid amount refers to that the field can be by the insect egg amount of Trichogramma;
(3) later stage protects effect and discharges: discharge oophagous trichogrammae in paddy rice booting latter stage to the fringe phase of beginning and be without prejudice to guarantee the later stage paddy rice; Burst size is 10000-15000 every mu;
Wherein, described trichogramma releases is to arrange 9-19 to put the honeybee point in every mu of rice field, and each puts the slotting bamboo pole that hangs with bee-escape of honeybee point, and the spacing between the adjacent bamboo pole is 8-9m, and the distance on bamboo pole and limit, field is 3-4m; Long 1.8-the 2.0m of described bamboo pole; The distance at described bee-escape and rice plant top is 30-50cm.
Described insect master evil is this area generic term for referring to that generation mainly occurs insect.
The invention will be further described below in conjunction with principle and advantage:
In the method for the present invention, before oophagous trichogrammae discharges, need investigation and analysis rice pest emergence date, egg-laying period, Development of egg to go through phase and spawning habit, the forecast of making prediction; Then, at investigation insect generation density and natural parasitic rate; At last, to numerous honeybee quality sampling check, investigate the simple grain emergence period, eclosion rate, male and female compare and become the honeybee vitality.Above foundation as determining to put the honeybee amount and put the inspection of honeybee effect.
It is before preventing and treating the purpose insect that low amount breeding discharges, discharge a small amount of oophagous trichogrammae and additional oophagous trichogrammae host egg, being allowed to condition at natural world relies on the host egg of other insect ovum or artificial supplementation to breed, thereby progressively enlarge the oophagous trichogrammae population quantity, to reach the purpose of the existing enough oophagous trichogrammae quantity in field when insect occurs, best release be period rice plant of tillering stage lepidoptera pest comprise striped rice borer, rice leaf roller, rice green caterpillar, the total moth amount of rice plant skipper and armyworm reaches every mu of 100-200 or every mu can parasitic insect ovum total amount reach the 10000-20000 grain, and putting the honeybee amount is every mu of 5000-10000.Low amount breeding method for releasing is suitable for the rice field of long-term ecological prevention and control rice field, minor pests laying particular stress on and the insect generation is irregular, the rice field of generation overlap, there is again the host egg of some in the field of putting honeybee for Trichogramma and breeding, below four kinds of situations feasible: first, for many years ecological prevention and control, the field insect assembly is many, the rice field that the oophagous trichogrammae host egg is abundant; The second, between the rice field other crop patch fields of plantation some, have the insect ovum of other crops can supply the breeding of oophagous trichogrammae with parasitic, such as lima bean pod borer, diamond-back moth etc.; The 3rd, the less important defoliator in rice field is the good middle host egg of oophagous trichogrammae, such as insects such as rice green caterpillar, rice plant skippers; The 4th, in the situation that Field Pests ovum deficiency, can discharge rice moth egg or the gelechiid ova of artificial propagation.
Dynamically control evil discharges applicable all ecological prevention and control rice fields, when the moth amount between general rice field reaches every mu of 150-200, put 10000 of honeybees for every mu, as put behind the honeybee in 4-7 days that the every mu of moth amount in field only surpasses 300-400 and during natural honeybee quantity not sufficient, need to mend anti-once, reaching the moth amount in field egg parasitoid amount does not need to put honeybee more than 30 times the time; General early rice discharges 1 time or does not discharge, and middle late rice discharges 1-2 time.
It is for guaranteeing that functional leaf is not subjected to the harm of the blade insects such as leaf roll snout moth's larva and rice green caterpillar that later stage protects that effect discharges, and the moth fringe insect such as striped rice borer is to the harm of spike of rice, booting latter stage to beginning the fringe phase, need put once protect after honeybee be without prejudice to guarantee the later stage paddy rice.Later stage is protected the applicable all ecological prevention and control rice fields of effect method for releasing, the Rice Growing later stage various insects take place frequently, the annual every Ji Junyou of the insects such as striped rice borer, leaf roll snout moth's larva and rice green caterpillar generation in various degree, therefore, the extermination of disease and insect pest of this phase is the critical period that oophagous trichogrammae discharges, and the worm amount all has the necessity of putting honeybee, and control efficiency is remarkable, put the honeybee amount and need to comprehensively determine general 10000-15000 every mu according to number of pest and field oophagous trichogrammae storage.
Trichogramma releases is mainly adopted ovum card method for releasing, namely the ovum card of the honeybee that will sprout wings is pasted into respectively in the bee-escape, and bee-escape should have rainproof, windproof, sunproof characteristics, generally selects preferably cardboard cup of disposable waterproof; Then opening down with bee-escape, so that the oophagous trichogrammae that sprouts wings freely flies out, the searching host; Bee-escape generally is hung on the bamboo pole of 1.8-2.0m with thick line or cord, and dried up rice plants top is 30-50cm approximately, and progressively raises with the growth of paddy rice.Put the diffusivity that how much depends on oophagous trichogrammae and the ovum card quantity of honeybee point between the rice field, oophagous trichogrammae is spreaded over a whole area from one point with circle to external diffusion, effective radius 10-15m, and the parasitic rate in 8-10m is the highest; Yet the range of scatter of oophagous trichogrammae and wind direction, wind speed and temperature are closely related, and scope of activities is larger with the wind, and suitable temperature also helps the diffusion of oophagous trichogrammae; According to the mobility of oophagous trichogrammae, 9-10 point put in general every mu of large-area rice field, and each point is inserted a long bamboo pole that hangs with bee-escape, spacing 8-9m between the bamboo pole, field back gauge 3-4m.Putting honeybee point should be according to the difference of landform and layout equably, better with quincunx distribution, also can adopt square.
This practical technique has been summed up the experience that forefathers apply, by research and improvement, now formed a cover and used concrete oophagous trichogrammae field release tech scheme, protected the effect method for releasing by low amount breeding method for releasing, dynamically control evil method for releasing and later stage and can effectively prevent and treat the insects such as striped rice borer in the rice field, rice leaf roller, rice green caterpillar, rice plant skipper and armyworm.The present invention has strengthened natural oophagous trichogrammae field survival ability, decrease put the honeybee cost, increased pest control effect, reduced the radix of snout moth's larva in the rice field, alleviate to chemical agent dependence be core technology that practicality is very strong in the green organic farming.This technology is an oophagous trichogrammae field release tech.
Specific implementation method
Embodiment 1
The rice field trichogramma releases is typically chosen in cloudy day or fine day, and the rainy day should not put honeybee.Oophagous trichogrammae light in the family way and the characteristic of sprouting wings in the morning, and daytime frequent activity, the habit that evening is static.Just can sprout wings fully in 1-3 days after oophagous trichogrammae discharges, the high temperature period time of sprouting wings just can shorten.Behind the Trichogramma 4-5 days, be the relevant damp state of black by parasitic ovum grain, 5 points of every mu of investigation, every some investigation 20-30 strains, to calculate the quantity of individual plant egg parasitoid, extrapolate field oophagous trichogrammae quantity, and estimate the eclosion rate of oophagous trichogrammae according to weather conditions at that time, for next trichogramma releases provides foundation.
Concrete release comprises the steps:
(1) low amount breeding discharges: in rice plant of tillering stage, trichogramma releases when the total moth amount of the lepidoptera pest that comprises striped rice borer, rice leaf roller, rice green caterpillar, rice plant skipper and armyworm reaches 100-200 every mu or every mu and can parasitic insect ovum total amount reaches 10000-20000, burst size is 5000-10000 every mu;
(2) dynamically control evil discharges: dynamically carry out target pest control for the generation of insect, according to target pest master evil long-term emergence period in generation and insect development progress, the moth emergence period of tentative prediction target pest, observe insect moth appearance and field moth emergence size situation at the moth appearance initial stage, insect moth appearance beginning Sheng phase trichogramma releases, burst size=moth amount * 30-field egg parasitoid amount * 70%;
(3) later stage protects effect and discharges: discharge oophagous trichogrammae in paddy rice booting latter stage to the fringe phase of beginning and be without prejudice to guarantee the later stage paddy rice; The burst size of oophagous trichogrammae is 10000-15000 every mu;
Wherein, described moth amount refers to behind the insect moth appearance quantity of moth in the rice field, and described field egg parasitoid amount refers to that the field can be by the insect egg amount of Trichogramma;
Described trichogramma releases is to arrange 9-19 to put the honeybee point in every mu of rice field, and each puts the slotting bamboo pole that hangs with bee-escape of honeybee point, and the spacing between the adjacent bamboo pole is 8-9m, and the distance on bamboo pole and limit, field is 3-4m; Long 1.8-the 2.0m of described bamboo pole; The distance at described bee-escape and rice plant top is 30-50cm.
The result of the test of the inventive method shows: the green production area of striped rice borer large tracts of land control effect is 69.61%-77.29%, and chemical control district preventive effect is 49.80%-93.14%.2009-2011 years green production areas of rice leaf roller large tracts of land control effect is 69.34%-87.10%, and chemical control district preventive effect is 46.52%-86.10%.Since Trichogramma can Sustainable Control rice leaf roller population in the field density, preventive effect is comparatively stable, same place between year difference less, and use the reasons such as the difference of chemical agent and spraying time and pesticide resistance thereof, cause the chemical control effect unstable, differ greatly.
