Embodiment 1

[0024] Attractant 1: 50 ul / mL camphor, the rest is liquid paraffin solution.

[0025] Attractant 2: 30 ul / mL camphor, 20 ul / mL γ-terpinene, and the balance is liquid paraffin solution.

[0026] The above-mentioned two attractants were used on Murata to detect the attractant effect on citrus psyllids. The experimental method was as follows: the prepared attractant 1 and attractant 2 (the control was an equal amount of liquid paraffin solution) were respectively taken Drop 1mL onto the cotton carrier, put it into a transparent plastic insect-attracting bottle, cover the bottle cap, there is a vent hole between the bottle cap and the bottle mouth, and then evenly spray a layer of transparent or yellow viscous on the periphery of the insect-attracting bottle. Shellac, respectively made into a transparent sticky bottle or a yellow sticky bottle, used to adhere to the trapped citrus psyllids. Hang the sticky worm bottle on the mulberry, and the hanging bottle is at the same height ...

Embodiment 2

[0030] The gamma-terpinene and aromatic camphor described in the attractant 2 in Example 1 are mixed in different proportions, and the balance is liquid paraffin solution to obtain the attractants of different proportions in the following table respectively. Said experimental method lures psyllids and statistical results are shown in Table 2:

[0031]

[0032] The results showed that when the volume ratio of γ-terpinene and camphor was 2:3 (the contents were 20 ul / mL and 30 ul / mL, respectively), the trapping effect on psyllids was the best (such as figure 1 ).

Embodiment 3

[0034] The attractant described in this example is improved on the basis of attractant 2 in Example 1, namely including γ-terpinene, α-pinene and linalool.

[0035] The formula of the attractant described in this example is: 2 ul / mL, 8 ul / mL, 3 ul / mL, and the balance is liquid paraffin solution. Also using the experimental method described in Example 1, the citrus psyllid was lured with the attractant described in this example. The trapping effect of this lure on citrus psyllids on Jiulixiang:

[0036] Transparent sticky insect bottle: The number of citrus psyllids trapped after hanging the bottle for 10 days was 10.2 heads / bottle, which was extremely different from the liquid paraffin control (only 0.4 heads / bottle), which was 25.5 times that of the control.

[0037] Yellow sticky insect bottle: The number of citrus psyllids trapped after hanging the bottle for 10 days was 24 heads / bottle, which was extremely different from the liquid paraffin control (only 0.6 heads / bottle...

Abstract

The invention relates to the fields of prevention and treatment of citrus plant diseases and insect pests, and particularly relates to a composition for trapping diaphorina citri kuwayama and an application method of the composition. The composition comprises gamma-terpinene, alpha-pinene and linalool. The method comprises the following steps: putting the prepared composition into a transparent plastic trapping bottle; covering by a bottle cap, and spraying an insect sticker outside the trapping bottle to prepare an insect sticking bottle; and hanging the insect sticking bottle on a host plant of the diaphorina citri kuwayama to trap and stick the diaphorina citri kuwayama, wherein the trap quantity of the composition under the condition of high diaphorina citri kuwayama density can be increased by 49.3 times, and the trapping quantity at low diaphorina citri kuwayama density is also increased by 5.17 times. The trapping effect of the composition is significant; the composition can be applied to prevention, treatment and prediction of the diaphorina citri kuwayama; and meanwhile, the propagated citrus yellow shoot is prevented.

Description

Technical field [0001] The invention involves the field of citrus disease and insect pest control, and more specifically, it involves a composition and how it is used to lure citrus wood lice. Background technique [0002] Orange lice Diaphorina citri (Kuwayama) is the main pest of the new period of citrus, and it is also the main disease of the citrus-the only media for the citrus yellow dragon disease.Citrus yellow dragon disease is the most dangerous infectious disease in the world's citrus industry. Because it has not found effective methods to prevent this disease at home and abroad, it can only be used to prevent the transmission of media insects in production.At present, chemical control of citrus lice is mainly used, that is, a large amount of chemical pesticides are sprayed in each new shooting period.In other issues, affect the safety of citrus, and ultimately reduce the economic value of citrus. [0003] Citrus lice are tender and yellowish. The existing technology has...
