Embodiment 1

[0029] Embodiment 1 Indoor lure example

[0030] 1. The olfactory response of adult citrus psyllids to a single dose of the secondary metabolites of Murata japonica

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

Embodiment 2

[0038] Embodiment 2 field trap example

[0039] 1. The formula of the attractant described in this example is: Mixture 1 (β-caryophyllene 33 μL / mL+D-limonene 50 μL / mL+linalool 17 μL / mL), mixture 2 (β-caryophyllene 43 μL / mL +D-limonene 43μL / mL+linalool 14μL / mL), mixture 3 (β-caryophyllene 25μL / mL+D-limonene 50μL / mL+linalool 25μL / mL), mixture 4 (β-caryophyllene 40μL / mL+D-limonene 40μL / mL+linalool 20μL / mL), the balance is mineral oil. Put 10mL of the prepared composition into a transparent plastic insect-attracting bottle, cover the bottle with a plurality of air holes on the surface of the insect-attracting bottle, and then evenly spray a layer of transparent or yellow sticky insects on the periphery of the insect-attracting bottle Glue is used to make transparent insect trap bottles or yellow insect trap bottles respectively, which are used to adhere and trap and kill citrus psyllids. Hang the insect trap bottle on the host plant of the citrus psyllid, and the insect trap bo...

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 prevention and control technology of citrus psyllid, and belongs 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 psyllid (Diaphorinacitrikuwayamae) belongs to the family Psyllidae of the order Homoptera. It mainly harms Rutaceae plants such as murella and citrus. The frequent occurrence of lice is an important factor for the prevalence of citrus huanglongbing. At present, citrus greening disease is gradually spreading in citrus planting areas around the world, and it is a major threat to the world's citrus industry. Thorough control of citrus psyllids is the premise and basis for preventing the spread of citrus huanglongbing. At present, chemical control measures are mostly used for the control of citrus psyllids. However, the frequent use of chemical pesticides has cau...
