Abstract
The utility model discloses a kind of ovum card device for discharging Harpactor fuscipes, including in the horizontal positioned columnar ovum casing clamping body of equilateral triangle prismatic, and with the integrally formed inverted U-shaped hanger plate of ovum casing clamping body, the bottom plate center of ovum casing clamping body is equipped with pieces of an egg rest area.The ovum card device of the utility model release Harpactor fuscipes is hung in field, waits egg hatchings imago/nymph to be diffused on tobacco leaf and preys on pest, it is possible to reduce the use of chemical pesticide can be effectively reduced persticide residue in tobacco leaf, reduce adverse effect of the pesticide to environment.
Description
Technical field
The utility model belongs to biological control of insect pests field, and in particular to one kind is for red in tobacco field release predator
The color ovum card device for really hunting stinkbug.
Background technique
Harpactor fuscipes [Harpactor fuscipes (Fabricius)] belong to Semiptera, Reduviidae, are mainly distributed on wide
The Main Tobacco-growing Regions In Souths such as east, Guangxi and Fujian, are the important Dominant Natural Enemies populations of Guangdong tobacco field.Its adult and nymph can prey on twill
Noctuid [Spodoptera litura (Fab.)], oriental tobacco budworm [Helicoverpa assulta (Guenee)] and cigarette aphid [Myzus
Persicae (Sulzer)] etc. tobacco-plant pest-insects.Harpactor fuscipes locomotivity is strong, can a wide range of host-location, Harpactor fuscipes
Two worm states that pest can be preyed on are respectively adult and nymph, and Harpactor fuscipes adult can prey on control oriental tobacco budworm and twill night
Moth mature larva, nymph can prey on rapidly the population quantity of the small individual pest such as cigarette aphid and prodenia litura low instar larvae, and nymph is every
It can prey on 50~100 cigarette aphids, and pest controlling ability is strong.Every piece of ovum has 20~40 after Harpactor fuscipes oviposition, is utilizing blusher
When really hunting stinkbug prevention and treatment tobacco field pest, conventional method is release adult and nymph, is prevented and treated pest.At present still not in field
Between hang Harpactor fuscipes ovum card pest control relevant report.
Utility model content
The purpose of this utility model is in view of the above-mentioned problems, a kind of ovum card device for discharging Harpactor fuscipes is provided, in field
Between hang Harpactor fuscipes ovum card device, wait egg hatchings imago/nymph to be diffused on tobacco leaf and prey on pest, chemistry can be reduced in this way
The use of pesticide can be effectively reduced persticide residue in tobacco leaf, reduce adverse effect of the pesticide to environment.
The technical scheme for implementing the utility model is as follows：
A kind of ovum card device discharging Harpactor fuscipes, including getting stuck in the horizontal positioned columnar ovum of equilateral triangle prismatic
Body, and with the integrally formed inverted U-shaped hanger plate of ovum casing clamping body, the bottom surface of ovum casing clamping body is provided with pieces of an egg rest area, and pieces of an egg are placed
Pest pieces of an egg rest area is provided with around area.
Ovum casing clamping body is formed by corrugated paper bending, and corrugated paper includes integrated molding and the identical first component of size, second
Component, third member and the 4th component, with third member as bottom surface, the first component and 60 degree of angles of the mutual bending of second component,
Second component and 60 degree of angles of the mutual bending of third member, the first component is Chong Die with the 4th component and is connected by viscose glue, forms water
The equilateral triangle prismatic column of placing flat.
Hanger plate is set to the 4th component side, is provided with inverted U-shaped tearing notch on hanger plate.
The beneficial effects of the utility model are：The ovum card device of the utility model release Harpactor fuscipes is hung in field,
Equal egg hatchings imago/nymph, which is diffused on tobacco leaf, preys on pest, it is possible to reduce the use of chemical pesticide can be effectively reduced in tobacco leaf
Persticide residue reduces adverse effect of the pesticide to environment, and the apparatus structure is simple, low in cost, is suitable for promoting.
Detailed description of the invention
Fig. 1 is the ovum card device structural schematic diagram that the utility model discharges Harpactor fuscipes.
Fig. 2 is the ovum card device expanded view that the utility model discharges Harpactor fuscipes.
Specific embodiment
The utility model is further described With reference to embodiment.
As shown in Figure 1 and Figure 2, a kind of ovum card device discharging Harpactor fuscipes, including in horizontal positioned equilateral triangle rib
The columnar ovum casing clamping body 10 of shape, and with the integrally formed inverted U-shaped hanger plate 20 of ovum casing clamping body.
Ovum casing clamping body 10 is formed by corrugated paper bending, corrugated paper include be integrally formed and the identical first component 11 of size,
Second component 12, third member 13 and the 4th component 14, with third member 13 as bottom plate, second component 12 and the 4th component 14
As side plate, the first component 12 and 13 60 degree of angles of mutual bending of second component, second component 14 and the mutual bending of third member 13
60 degree of angles, the first component 11 is Chong Die with the 4th component 14 and is connected by viscose glue, forms horizontal positioned equilateral triangle prismatic column.
Two pieces of side plate tops link together, and can play the function that is protected from light and takes shelter from rain.
The bottom plate center of ovum casing clamping body be equipped with pieces of an egg rest area 15, including place Harpactor fuscipes center pieces of an egg rest area and
A circle prey ovum grain rest area 16 around Harpactor fuscipes pieces of an egg rest area.
Hanger plate 20 is set to 14 side of the 4th component, and inverted U-shaped tearing notch 21 is provided on hanger plate 20, is gently torn
After can hang on tobacco leaf or other plant petioles.
In use, the Harpactor fuscipes pieces of an egg paper that will hatch is sticked to first the center pieces of an egg rest area of ovum card device
15, the rice moth egg or Trichogramma pupae of equivalent are put in a circle prey ovum grain rest area 16 outside the rest area of pieces of an egg center,
For Harpactor fuscipes incubates nymph feeding, kill each other to prevent there is no prey feeding after incubates nymph hatching.Then by corrugation
Paper first part 11 and 12 bending of second part, 60 degree angles, second part 12 and 13 bending of Part III, 60 degree of angles, then by the
A part 11 is sticked together with Double-face gummed paper 111 or is ordered together with stapler with Part IV 14.Finally by 20 edge of hanger plate
After being torn at tearing notch 21, pieces of an egg device is held at the petiole of cigarette strain Different sites of leaf, thus by Harpactor fuscipes ovum card
It hangs in cigarette strain.After Harpactor fuscipes egg hatching, can first feeding prey ovum grain rest area rice moth egg or artificial eggs trichogramma
Then pupa is diffused on tobacco leaf and finds predation cigarette aphid, oriental tobacco budworm and Spodoptera litura larvae.
Above-listed detailed description is illustrating for the utility model possible embodiments, and the embodiment is not to limit
The scope of the patents of the utility model, all equivalence enforcements or change without departing from carried out by the utility model, is intended to be limited solely by this case
In the scope of the patents.
