Embodiment 1

[0029] Example 1 Indoor Attraction Example

[0030] 1. The olfactory response of the adult citrus psyllid to a single dose of the secondary metabolite of Jiulixiang

[0031] A Y-type olfactory instrument was used for testing, and the two arms were connected to the taste source bottle (100mL), humidification bottle (100mL), filter (activated carbon) device and air pump with Teflon tubes respectively, and the gas flow rate in the two arm tubes was 200mL / min. The test is carried out at 10:00~17:00, 25-28°C. The following odor sources were set: β-caryophyllene 10 μL / mL, D-limonene 10 μL / mL, and Linalool 10 μL / mL. Dilute the secondary metabolites 100 times with mineral oil as the test solution, take 100 μL / drop of the volatile secondary metabolite solution on the filter paper in the flavor source bottle, and use mineral oil as the control. One adult worm was inserted each time, a total of 30 worms were tested and repeated 3 times. When an adult crosses 1 / 3 of an arm, it is regarded a...

Embodiment 2

[0038] Example 2 Field trapping example

[0039] 1. The formulation of the attractant described in this example is: mixture 1 (β-caryophyllene 33μL / mL+D-limonene 50μL / mL+linalool 17μL / mL), mixture 2 (β-caryophyllene 43μL / mL +D-limonene 43μL / mL+linalool 14μL / mL), mix 3 (β-caryophyllene 25μL / mL+D-limonene 50μL / mL+linalool 25μL / mL), mix 4 (β-caryophyllene 40μL / mL+D-limonene 40μL / mL+linalool 20μL / mL), the balance is mineral oil. Put 10 mL of the prepared composition into a transparent plastic trap bottle, cover the cap, the surface of the trap bottle has multiple vents, and then evenly spray a layer of transparent or yellow armyworm on the periphery of the trap bottle Glue, respectively made into a transparent trap bottle or a yellow trap bottle, used to adhere to trap citrus psyllids. Hang the trap bottle on the host plant of citrus psyllids, the height of the trap bottle and the host plant or slightly lower than the height of the host plant (such as figure 1 ).

Abstract

The invention discloses a composition for trapping and killing diaphorina citri kuwayama, and a using method and the application thereof. The composition comprises beta-caryophyllene, D-limonene, linalool and the balance of mineral oil, wherein the volume ratio of the beta-caryophyllene to the D-limonene to the linalool is (1-3):(2-3):1, and the content of the beta-caryophyllene is 4.3 to 43 mu L / mL, the content of the D-limonene is 4.3 to 43 mu L / mL and the content of the linalool is 1.4 top 14 mu L / mL. The composition for trapping and killing the diaphorina citri kuwayama provided by the invention has a better trapping effect than that of trapping with yellow sticky cards; the trapping number of the composition can be improved by 25.1 times when the density of the diaphorina citri kuwayama is high (murraya paniculata serves as a host), and the trapping number can also be improved by 20.4 times when the density of the diaphorina citri kuwayama is low (citrus gonggan serves as a host), so that the trapping effect is remarkable. The using method of the composition disclosed by the invention is simple and feasible; compared with the current chemical agent for preventing and controlling the diaphorina citri kuwayama, the composition has the advantages of high efficiency, greenness, environmental friendliness, strong lasting effect and the like, does not have pollution to the environment, and does not have residues.

Description

Technical field [0001] The invention relates to the control technology of citrus psyllid, belonging to the technical field of physical control, and more specifically, relates to a composition for trapping and killing citrus psyllid and its use method and application. Background technique [0002] Citrus psyllids (Diaphorina citri kuwayamae) belong to the Homoptera Psylidae family. They mainly damage Rutaceae plants such as murraya and citrus. It is one of the most harmful pests on citrus and the only vector of citrus Huanglongbing (Huanglongbing). The frequent occurrence of citrus psyllids is an important factor in the epidemic of citrus yellow dragon disease. Citrus yellow dragon disease is gradually spreading in citrus growing areas around the world and is a major threat to the world's citrus industry. Thorough control of citrus psyllids is the prerequisite and basis for preventing the spread of citrus yellow dragon disease. At present, chemical control measures are mostly use...
