Abstract
The utility model provides a wasp releasing device suitable for releasing parasitic wasps in a water field to prevent and treat rice grubs. The wasp releasing device is composed of a cup body and a cup cover, wherein a funnel-shaped partition plate is arranged inside the cup body; a bearing space is arranged on the lower part of the cup body; a space for placing host eggs is arranged on the upper part of the cup body; a parallel-surrounding outer edge is arranged on the outer part of the cup body; a plurality of wasp outlets are distributed at the outer caliber; the outer edge of the cup cover is expanded in an arc-shaped manner, and locked with the cup body to keep the wasp outlets to not be sealed. When the wasp releasing device disclosed by the utility model is used for releasing wasps in the field, an operator does not need to go to the field, but walks on a rice-field pool bank to throw the wasp releasing device with certain weight into the water field, the bottom of the wasp releasing device is firstly dropped into the water under action of gravity, the wasp releasing device does not sink into water bottom under action of floating force of the cup body outer edge, an upper space with trichogramma is floated on the water surface, so that a little water enters from the wasp outlets and flows into the lower space with sands. The wasp releasing device can be used for preventing predators from eating the host eggs, and preventing rains, is not accumulated with water and is capable of realizing mechanical production.
Description
Technical field
What the utility model related to that a kind of applicable paddy field discharges parasitic wasp control rice grub puts honeybee device, and particularly a kind of oophagous trichogrammae of applicable paddy field application is put honeybee device, belongs to agricultural technology field.
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.The common insect of the paddy rice of causing harm has kind more than 30.In the Severe pests of China crops, rice grub surpasses 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 having, as rice water weevil.In these insects, most kinds are lepidoptera pest, and they are by eating into stem and stinging food blade and cause serious economic loss.For example, striped rice borer is caused harm with larva moth stem, can cause withered sheath, the withered heart and dead ears, and rice strain effective tiller is reduced, and ripening rate reduces, and thousand kernel weight declines, northeastward area do not prevent and treat that field causes harm because of snout moth's larva can the underproduction approximately 20%, serious plot can the underproduction 50% left and right.
Infection and damage for Severe pests on paddy rice, chemical pesticide remains the Main Means of current control, the unreasonable use of agricultural chemicals causes the agricultural chemicals drift of 70%-80% or is 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 cause the insect pests such as striped rice borer to produce high drug-resistance, have to strengthen agricultural chemicals using dosage, be absorbed in the vicious circle that agricultural chemicals is used, had 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 organic rice demand is improved day by day.Therefore, these insects are implemented to green prevention and control, 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 the natural enemy insect that utilizes in the world the most extensively and apply area maximum at present, and numerous species is put honeybee for the control of agriculture and forestry injurious insect by successful amount reproduction.In rice grub is administered, just there are the yellow oophagous trichogrammae of snout moth's larva and Trichogramma successfully to prevent and treat the report of rice-stem borer and rice leaf roller.In oophagous trichogrammae batch production production process, substantially all adopt large ovum (egg of oak silkworm), ovule (rice moth egg, gelechiid ova) and artificial false ovum to breed as vector, the bee-escape matching with it and put honeybee method and also have many reports.As being applicable to egg of oak silkworm, breed the honeybee method of putting of oophagous trichogrammae and " utilize the method for boxlike bee-escape single step of releasing honeybee control of maize snout moth's larva " (application number 200610017085.X), and relevant honeybee device " bag-type bee-escape for trichogramma " (patent No. CN2358678Y) and " box type bee discharging device for trichogrammatid wasps " (patent No. CN2930274Y) put, oophagous trichogrammae bee-escape " little parasitic bee bee-escape " (patent No. CN202374894U) and " little egg parasite is put honeybee device " (patent No. CN202514445U) of applicable 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-escapes in paddy field and putting honeybee oophagous trichogrammae, the artificial suspension of need to going to the field, it is very inconvenient to operate.
Summary of the invention
What the utility model disclosed that a kind of applicable paddy field discharges parasitic wasp control rice grub puts honeybee device, is 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 and in the field of the particular surroundings of paddy field control of insect, puts honeybee for host breeds oophagous trichogrammae.
what the utility model disclosed that a kind of applicable paddy field discharges parasitic wasp control rice grub puts honeybee device, and the technical solution of employing is:
By cup and bowl cover, formed, 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 to be sealed simultaneously.
Described cup, bowl cover, dividing plate, the outer rim ring of putting honeybee device is corn starch biodegradation material and makes.
When the utility model is used, area be the paddy field of 1 mu (667 square metres) jettisoning 3 ~ 5 contain Trichogramma put honeybee device.In the load-bearing space of putting honeybee device, inject mass, in host egg space, put into the ovum of breeding parasitic wasp; Again lid is buckled on cup and is integrally formed; The honeybee device of putting that contains parasitic wasp is evenly jettisoninged in paddy field, make it automatically float on the water surface, the ovum of parasitic wasp initiatively climbs out of and searches insect host egg from going out bee-hole after sprouting wings.
good effect of the present utility model is:when honeybee is put in field, operator need not descend paddy field, on the Chi Geng of rice field, the honeybee device of putting with constant weight can be thrown in paddy field, under Action of Gravity Field, put honeybee bottom of device and first fall into the water, under the effect of cup outer rim ring buoyancy, putting honeybee 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 the lower space that fills sand by funnel-form dividing plate; Avoid predator to the taking food of host egg, prevent from drenching with rain, ponding not, and can realize mechanization production.Putting honeybee device making material and be corn starch biodegradation material, is degradable under field conditions (factors) about 6 months, can be to environment.
