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 rate of the female and male moths of the pear borer moth flying to more than 1 / 2 distance in the wind tunnel is 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 Figure 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 an obligate attractant for controlling oriental fruit moths and a control method. The effective components are sugar acetate and alcohol liquid and a host plant volatile matter which are mixed, wherein in the sugar acetate and alcohol liquid, the ratio of soft sugar to glacial acetic acid to absolute ethyl alcohol to water is 3 g:1 ml:3 ml:80 ml; in the host plant volatile matter, the ratio of nonanal to cis-3-hexenolacetate to 6-methyl-5-heptene-2-ketone to (Z)-beta-ocimene is 14:100:1:86, and the solubility of solvent n-hexane used for the host plant volatile matter is 1 mu g / mu l; the sugar acetate and alcohol liquid and the host plant volatile matter are mixed according to the volume ratio of 1:1. Through action of long-distance attraction of a food attractant and near-distance attraction of the oviposition attractant, not only is the control effect ensured, but also chemical pesticide reduction is propelled; green prevention and control product and technology popularization is accelerated; the obligate attractant and the method are beneficial to protecting the ecological environment and ensuring thefood safety and ecological safety and are beneficial to 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...
