Problems solved by technology

[0004] However, it is difficult to artificially raise the adults of A. japonica, and it is impossible to store the adults in a low-temperature environment for a long time. Therefore, it is difficult to realize regular and quantitative supply throughout the year. In addition, because of the strong migration ability of A. , once the environment is not suitable due to food shortage and other reasons, its colonization will be seriously affected, making long-term pest control difficult to achieve
And through multiple releases and supplements, it will increase the cost of prevention and control

Embodiment 1

[0042] Embodiment 1: Citrus psyllid body shape characteristics

[0043]Female and male citrus psyllid adults were collected separately, and the collected citrus psyllid adults were placed in a -20°C refrigerator for 10 minutes, and the body length, body width and body height of each adult were measured with an online stereoscope.

[0044] Table 1 Body size measurement results of citrus psyllid adults (M±SM, mm)

[0045]

[0046] It was found that the adult females and males of citrus psyllids were very similar in body size, with no significant difference. The body widths were 0.677mm and 0.677mm, and the body heights were 0.693mm and 0.701mm, respectively. The body width was slightly smaller than the body height. Therefore, in order to prevent adult citrus psyllids from passing through, the pore size of the insect-proof net should not be greater than 0.693mm.

Embodiment 2

[0047] Embodiment 2: body shape characteristics of bright belly glaze wasp

[0048] The female and male adults of A. japonica were collected separately, and the collected adults of A. japonica were placed in a -20°C refrigerator for 10 minutes. The body length, body width, head length and head width of each adult were measured with an online stereoscope.

[0049] Table 2 Measurement results of body size of the adults of A. japonica (M±SM, mm)

[0050]

[0051] The results showed that there was a significant difference in body size between the female and the males of A. japonica, and the females were significantly larger than the males. The body and head widths of the female japonicas were 0.386 mm and 0.392 mm, respectively, and the body and head widths of the male japonicas were 0.330 mm and 0.330 mm, respectively. 0.356mm, the head width of the two is greater than the body width, so it is determined that the aperture of the insect-proof net that allows the wasp to pass th...

Embodiment 3

[0052] Embodiment 3: Determination of the mesh aperture in the multiplication protection mesh cover in the carrier plant system

[0053] By measuring the body characteristics of the citrus psyllid and the citrus psyllid, it can be found that the body size of the citrus psyllid is much smaller than that of the citrus psyllid, thus confirming that there is an insect-proof net with a specific pore size, which can prevent the host while allowing the citrus psyllid to pass through. Insects pass. According to the body size measurement results of citrus psyllids and citrus psyllids, it can be preliminarily determined that the pore size range of the insect-proof net that allows citrus psyllids to pass through while preventing citrus psyllids from passing through should be between 0.392 and 0.693 mm. The aperture deformation of the medium insect-proof net affects the test results, and the insect-proof net selected is a metal mesh.

[0054] During the test, 100 (half male and half fema...

Abstract

The invention discloses a carrier plant system, a constructing method and an application of A. japonica. In the carrier plant system of the present invention, the carrier plant is Murata japonica, the host is citrus psyllid, and the parasitic natural enemy is A. japonica, which also includes a proliferation protection net cover; the constructed carrier plant system is placed in a suitable temperature, humidity and light Under certain conditions, the natural enemy multiplication is completed; the use method of the carrier plant system of the present invention is to select different numbers of bright-bellied wasps to be inserted into the carrier plant system according to the occurrence degree of psyllid pests in the citrus orchard, and to complete the bright-bellied wasps through the proliferation protection net cover. release. The carrier plant system of the present invention is beneficial to the proliferation and protection of natural enemies, and can effectively inhibit citrus psyllids; according to actual needs, this net-type carrier plant system can be placed in the orchard in time to increase the biological activity of citrus psyllids. Timeliness and pertinence of prevention and control.

Description

technical field [0001] The invention belongs to the technical field of biological control of agricultural pests, and in particular relates to a carrier plant system of the japonica japonica and its construction method and application. Background technique [0002] Citrus psyllid (Diaphorina citri Kuwayama) is the main pest of citrus plants in the young shoot stage. The adults are scattered on the leaves and new shoots of the plants, suck the plant juice through the piercing-sucking mouthparts, and after mating, lay eggs on the new shoots. shoots, young leaves, and tender shoots, while the newborn nymphs continue to harm the plants, causing the buds, shoots, and leaves of the sucking parts to shrink and distort, and during the development process, excrete white secretions, which will cause the occurrence of plant soot . What's more serious is that the citrus psyllid, as the only natural carrier of citrus destructive disease Huanglongbing, often leads to outbreaks of Huanglon...
