Description
Technical field
The present invention discloses a kind of method of applicable paddy field release parasitic wasp pest control, provides corresponding releasing device simultaneously, belongs to pest technical field of biological control.
Background technology
Paddy rice is the main cereal crops of China, in cereal crops, accounts for 26% of total area under cultivation, accounts for 43% of total grain yield.Paddy rice common insect pests of causing harm has kind more than 30.In the Severe pests of China crops, rice grub exceedes half.Wherein, some pest species occurs throughout the year, as striped rice borer, paddy stem borer, pink rice borer, rice leaf roller, brown planthopper etc.; Some kind some areas occurs, as rice plant skipper, rice leaf beetles; Some kind is intermittent large generation, as armyworm; The insect for recently importing into had, as rice water weevil.In these insects, most kind is lepidoptera pest, and they cause serious economic loss by eating into stem and stinging food blade.Such as, striped rice borer is caused harm with larva moth stem, and can cause withered sheath, the withered heart and dead ears, rice strain effective tiller is reduced, ripening rate reduces, thousand kernel weight decline, northeastward area do not prevent and treat that field causes harm because of snout moth's larva can the underproduction about 20%, serious plot can the underproduction about 50%.
For the Infection and damage of Severe pests on paddy rice, chemical pesticide remains the Main Means of control at present, the unreasonable use of agricultural chemicals causes the agricultural chemicals of 70%-80% drift about or be lost in non-target organism, soil and waters, serious pollution of ecological environment, indiscriminate use of pesticide is a large amount of killed natural enemies not only, also causes the insect pests such as striped rice borer to produce high drug-resistance, has to strengthen Pesticide use dosage, be absorbed in the vicious circle of Pesticide use, have a strong impact on rice yield, rice quality and kind rice benefit.Along with the continuous lifting of living standards of the people, green consumption idea is progressively rooted in the hearts of the people, and day by day improves organic rice demand.Therefore, implement green prevention and control to these insects, particularly utilizing natural enemy insect to carry out biological control is inexorable trend.
Oophagous trichogrammae is a most important class egg parasitoids in lepidoptera pest biological control, is at present to utilize the most extensively and apply the maximum natural enemy insect of area in the world, and numerous species has been used for the control of agriculture and forestry injurious insect by successful amount reproduction release.In rice grub is administered, just there is the report of Trichogramma chilonis and Trichogramma success water prevention chilo suppressalis and rice leaf roller.In oophagous trichogrammae factorial praluction process, large ovum (egg of oak silkworm), ovule (rice moth egg, gelechiid ova) and artificial false ovum is substantially all adopted to breed as vector, the bee-escape matched with it and put honeybee method and also have many reports.The method for releasing of breeding oophagous trichogrammae as applicable egg of oak silkworm " utilizes the method for boxlike bee-escape single step of releasing honeybee control of maize snout moth's larva " (application number 200610017085.X), and relevant releasing device " bag-type bee-escape for trichogramma " (patent No. CN2358678Y) and " box type bee discharging device for trichogrammatid wasps " (patent No. CN2930274Y), be applicable to oophagous trichogrammae release " little parasitic bee release " (patent No. CN202374894U) and " little egg parasite releasing device " (patent No. CN202514445U) of little parasitic bee.The design of these bee-escapes and use are confined to the control of lepidoptera pest in field crop or forestry substantially, do not consider the particular surroundings of rice plant and paddy field operation, when applying these bee-escape trichogramma releases in paddy field, need artificial suspension of going to the field, it is very inconvenient to operate.
Summary of the invention
The present invention discloses a kind of method of applicable paddy field release parasitic wasp pest control, and being applicable to large ovum (egg of oak silkworm, Eggs of Philosamia Cynthia Ricini), ovule (rice moth egg, gelechiid ova or Eggs of Diamondback Moth) or artificial false ovum is that host breeds the field adaptability of oophagous trichogrammae in the particular surroundings of paddy field control of insect.
What present invention also offers the method for applicable paddy field release parasitic wasp pest control puts honeybee device; the parasitic wasp releasing device that rational in infrastructure, protective effect is comprehensive, easy and simple to handle, being applicable to large ovum (egg of oak silkworm, Eggs of Philosamia Cynthia Ricini), ovule (rice moth egg, gelechiid ova and Eggs of Diamondback Moth) and artificial false ovum is the field adaptability that host breeds oophagous trichogrammae.
the present invention discloses a kind of method of applicable paddy field release parasitic wasp pest control, and the technical solution of employing is:
Inject mass in the load-bearing space of releasing device, put into the ovum of breeding parasitic wasp in host egg space; Again lid is buckled on cup and is integrally formed;
Releasing device containing parasitic wasp is evenly jettisoninged in paddy field, makes it automatically float on the water surface, initiatively climb out of from going out bee-hole and search insect host egg after the ovum emergence of parasitic wasp;
Above-mentioned honeybee device of putting is made up of cup and bowl cover, wherein: the inside of cup is provided with a funnel-form dividing plate, cup is divided into the load-bearing space of bottom and the host egg space on top; The rim of a cup edge of cup is uniformly distributed 3-5 and goes out bee-hole; The middle part cover of cup has an outer rim ring; The curved abduction of outer rim of described bowl cover, is integrally formed structure after fastening with cup, keeps bee-hole not airtight simultaneously.
The cup of described releasing device, bowl cover, dividing plate, outer rim ring are corn starch biodegradation material and make.
When the present invention uses, area is jettisoning 3 ~ 5 releasing devices containing Trichogramma in the paddy field of 1 mu (667 square metres).
good effect of the present invention is:when honeybee is put in field, operator need not descend paddy field, the releasing device with constant weight can be thrown in paddy field by rice field Chi Geng, under gravity, first fall into the water bottom releasing device, under the effect of cup outer rim ring buoyancy, releasing device can not sink under water, the upper space that oophagous trichogrammae is housed can float on the water surface, immediately has a small amount of water to enter from going out bee-hole, also can flow into by funnel-form dividing plate the lower space filling sand; Avoid predator taking food host egg, prevent from drenching with rain, not ponding, and can mechanization production be realized.Releasing device makes material and is corn starch biodegradation material, within about 6 months, is degradable under field conditions (factors), can not to environment.
