Fig. 1 is a schematic structural view of a breeding device for citrus mealybugs according to embodiment 1 of the present invention.
In the figure: 1-pumpkin; 2-a culture room; 3-water; 4-a support member.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The embodiment of the invention provides a method for breeding a scale insect, which comprises the following steps:
pumpkin is used as a host, water is used as isolation, the pumpkin used as the host is placed above the water surface, the pumpkin is not contacted with the water through a supporting piece, and then eggs or larvae of the mealybugs are inoculated on the pumpkin for cultivation. Specifically, the oocysts at the tail of the citrus mealybugs can be picked, eggs (red) in the oocysts are taken out, and the taken eggs are uniformly coated on the surface of the pumpkin; in addition, the pumpkin with the citrus mealybugs can be stacked on the pumpkin with the citrus mealybugs for cultivation.
Example 1
As shown in fig. 1, this embodiment provides a device for cultivating citrus mealybugs, which includes:
a culture room 2; water 3 is arranged in the culture room;
at least one pumpkin 1, which is used as a host of the mealybugs;
at least one set of supports 4 for supporting the pumpkin 1 so that the pumpkin 1 does not come into contact with the water 3 in the cultivation room 2; the support 4 is arranged in the water 3 inside the culture chamber 2; the pumpkin 1 is arranged on the supporting piece 4, and the supporting piece 4 is made of waterproof materials.
Specifically, the breeding room 2 can adopt a disc-shaped structure made of waterproof materials, or adopts a seedling raising water pool with the specification of 70cm multiplied by 12 cm; 1 part of pumpkin is the common pumpkin sold on the market, and a plurality of pumpkins 1 can be placed or stacked in multiple layers; the supporting member 4 can be made of a building plate brick or a stone which is commonly available on the market, and the upper surface of the supporting member needs to be smooth and flat so as to be convenient for placing the pumpkin 1.
As another preferable scheme of the embodiment of the invention, the water level in the culture room 2 is lower than the height of the support 4, so as to ensure that the water 3 can be prevented from contacting with the water when being placed on the support 4, therefore, the mealybugs can grow on all the surfaces of the pumpkins 1, and the problem that the pumpkins 3 are easy to mildew on the water can be prevented. Specifically, the height of the water surface in the culture room 2 can be 1-5 cm.
Example 2
The embodiment provides a method for breeding a mealybugs using the breeding device provided in embodiment 1, which specifically includes the following steps:
(1) water is poured into the breeding chamber 2, and a plurality of groups of supporting pieces 4 are placed in the water 3 to ensure that the upper surface of the citrus mealybugs is exposed to the water surface.
(2) A plurality of layers of squash 1 are placed on the support 4 and the squash 1 is kept out of contact with the water 3.
(3) Inoculating the eggs or larvae of the scale canicillium citrosum to the pumpkin for cultivation.
(4) Because the colony of the scale mealybugs expands, the scale mealybugs spread from the lower part to the upper part and spread to the top end and then spread all around, the seeding is started from the bottom layer pumpkin 1, and the evenly-expanded scale mealybugs colony can be obtained. Specifically, the oocysts at the tail of the citrus mealybugs are picked up, eggs (red) in the oocysts are dipped by a writing brush, and then the dipped eggs are uniformly smeared on the surface layer of the bottom layer pumpkin 1, wherein the inoculation amount of the citrus mealybugs can be controlled to be 10 eggs/cm2. In addition, when the citrus mealybugs grow on the bottom layer pumpkin 1, the new pumpkin without the citrus mealybugs can be directly stacked on the pumpkin with the citrus mealybugs (the pumpkin with the citrus mealybugs can be cleaned by a writing brush in advance to remove the citrus mealybugs which are easy to be killed), and the natural inoculation can be completed after 24 hours.
(5) After the citrus mealybugs are covered on the surface layer of the pumpkin 1, the citrus mealybug communities on the surface layer of the pumpkin 1 can be scraped by using a writing brush or thick paper so as to finish the cultivation of the citrus mealybugs. Wherein, because the cortex of the scale canicillium citrosum is soft and has large water content, the bred scale canicillium citrosum community can be directly used as a feed to feed natural enemy insects such as harmonia axyridis or coccinella septempunctata. In addition, because the citrus mealybugs grow in a colony mode, colonies of the citrus mealybugs are stacked together in the culture process, and the citrus mealybugs need to be frequently taken out to reduce the thickness of the colonies, so that the growth and propagation of the mealybugs at the bottom layer are facilitated.
It should be noted that, because the eggs of the citrus mealybugs can spread with the wind and can harm the surrounding crops, the cultivation room 2 can be placed in an indoor windless environment, and cannot be placed in an outdoor ventilated environment. In addition, the growth efficiency of the citrus mealybugs can be influenced by exposure to the sun and rain, and the pumpkins are easy to mildew, so that the cultivation room 2 cannot be placed in the open air. In addition, because the pumpkin after being washed by water is easy to rot, the surface of the pumpkin before being used is not washed by water as much as possible, and the pumpkin can be dried in advance if necessary.
