Embodiment 1

[0013] Example 1: Field trapping effect experiment of different ratios of sweet and sour liquor on the male and female pear borer worms. The different ratios of sweet and sour liquor are shown in Table 1. The ratio of sweet and sour liquor with the best trapping effect on both male and female pear borer worms was 3 : 1 : 3 : 80 through screening.

[0014] Table 1 Different ratios of sweet and sour liquor

[0015]

[0016] There were significant differences in the trapping amount of male pear borer moths with different ratios of sweet and sour liquor in the field ( F =2.24, df=9,39, P =0.047), there was no significant difference in the amount of trapping females ( F =1.889, df=9,39, P =0.093). Among them, the average trapping quantity of both male and female insects reached the maximum at ratio 7 (1.25±0.48 and 24.00±10.70). Ratio 1, 2 and 4 failed to trap females, and the trapping amount of males in the blank control was the smallest. ( figure 1 )

Embodiment 2

[0017] Example 2: Experiments on the effect of different ratios and doses of host plant volatiles on the field trapping effect of female and male moths of pear borer moths. The ratio and dose of host plant volatiles are shown in Table 2. The proportion and dose of volatiles in host plants with the best trapping effect on both male and female pear borer worms were obtained through screening: nonanal: cis-3-hexenol acetate: 6-methyl-5-heptene -2-keto:(Z)-β-ocimene=14:100:1:86 ratio, 0.201mg dose.

[0018] Table 2 The ratio and dose of volatiles in host plants

[0019]

[0020] The field moth-attracting effect of host plant volatile components was not significantly different under the combined effects of ratio and dosage ( F = 0.560, df= 6, 56, P = 0.76), the same difference was not significant under individual ratio or dose effects (dose: F =0.217, df = 1, P = 0.446; Scale: F = 1.317, df = 6, P = 0.271). In terms of dosage, 0.1× has the highest moth-attracting am...

Embodiment 3

[0021] Embodiment 3: Contrast experiment of sweet and sour liquor, host plant volatile matter and the obligate lure method used in combination on the lure of pear borer. The antennal potential was used to detect the reactivity of the antennae to the odor indoors, and the flight behavior induced by the odor was measured through the wind tunnel to simulate the field activity space, and finally the trapping effect was tested in the field. See image 3 . The directional flight response rate of the female and male moths of the pear borer moth, see Figure 4 . The response rates of the female and male moths of the pear borer moth flying to more than 1 / 2 distance in the wind tunnel are shown in Figure 5 . The female and male moths of the pear borer moth approach the odor source within 10cm or the landing reaction rate see Image 6 . Specific lure method in the field to attract moths of the small pear borer, see Figure 7-9 . In the figure: PP means host plant volatile matter...

Abstract

The invention belongs to the technical field of pest attractants, and provides a specific attractant and control method for preventing and controlling pear borer moth. : absolute ethanol: water=3g:1ml:3ml:80ml; host plant volatile matter: nonanal, cis-3-hexenol acetate, 6-methyl-5-heptenyl-2-ketone, (Z )‑β‑Ocimene=14:100:1:86, the host plant volatiles were dissolved in n-hexane as a solvent to 1 μg / μl; the sweet and sour liquor and the host plant volatiles solution were mixed at a volume ratio of 1:1. Through the long-distance lure of food attractants and the short-distance lure of oviposition attractants, the reduction of chemical pesticides is promoted while ensuring the control effect. Accelerate the promotion of green prevention and control products and technologies. It is conducive to protecting the ecological environment, ensuring food safety and ecological security, and is conducive to the sustainable development of agriculture.

Description

technical field [0001] The invention belongs to the technical field of pest luring, and in particular relates to an obligate attractant and a control method for preventing and treating the small pear borer. Background technique [0002] With the optimization and adjustment of the agricultural industrial structure, the fruit market has become the second largest agricultural product market after the grain market. The healthy development of the fruit industry is crucial to the realization of my country's agricultural efficiency, rural development, and farmers' income. Pests and diseases have a great impact on fruit tree production. There is a large area of ​​deciduous fruit tree cultivation areas in northern my country. Peach, pear, and apple are the main cultivated species, and pear small borer Grapholitha molesta (Busck) is a very serious harm of fruit borer pests, bringing devastating harm to the fruit industry. The small pear borer can harm the young shoots and fruits o...
