Food-luring composition aiming at cydia pomonella larvae and adults and application of food-luring composition

Abstract

According to harm objects of codling moths, volatile matters liked by the codling moths exist in harm plants of the codling moths. Therefore, the volatile matters of the plants are qualitatively and quantitatively analyzed, the attraction effect of the compounds on the codling moths is measured at the same time, and finally a single compound and a composition with a high attraction effect on the codling moths are obtained.

Description

Technical Field

[0001] The present invention relates to the field of agricultural pest control, and in particular to a composition and an application method thereof for controlling the apple moth that harms fruit trees, such as pear trees, peach trees and plum trees, by using a food-attractant combination at different growth stages. Background Art

[0002] The fruit moth harms fruit trees, causing serious economic losses. Traditional chemical pesticide control methods are only effective before the fruit moth bores into the fruit or after it becomes an adult. At other times, the insect body is bored into the fruit of the plant, making it difficult for the pesticide to reach the insect body. The purpose of controlling the pest cannot be achieved. Therefore, it is necessary to find a more environmentally friendly and efficient control method. The time of entering the parasitic fruit or luring the pests that have bored into the plant body can be delayed, giving the chemical control agent more time window to contact the insect body, which can improve the control effect of the fruit moth. Summary of the invention

[0003] The purpose of the present invention is to provide a food attractant for codling moths prepared by using a single substance of fruit tree volatiles or a mixture of several volatiles. The food attractant can be mixed with conventional pesticides to control codling moths of different ages. The food attractant has the characteristics of environmental protection and high efficiency.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a combination of volatiles of fruit tree moths, containing the following volatile components: anise ketone, α-pinene, hexyl butyrate, β-pinene, pinane, styrene, rhodol, cis-3-hexen-1-ol, cis-3-hexenyl, linalool, isopentene, trehalone, α-origanin, β-farnesic acid, α-longifolia aldehyde, 2-acetylpyrrole, β-gallinal, nonanal, β-glutenol, ethyl 2,4-decadienol, n-butyl sulfide, α-p-acetylacetate, 2-methyl-1-butanol, β-citronellol, β-myrcene, isoocimene, pinocalafin, dianthus oxide ene, benzaldehyde, β-tridecene, limonene, jasmone, mung bean ketone, vanillin, acetone aldehyde, melicyclazole, ethyl acetate, styrene, trimethylstyrene, phenylacetaldehyde, limonene, geraniol, 3-ethyl pentanoate, 2-ethyl pentanoate, propylene glycol, hexanoic acid, nonanol, β-myrcene-2-one, eucalyptus alcohol, p-isoprene, eugenol, citronellol, narcissin, pentenal, octenes, cis-thymaldehyde, methyl acrylate, α-eudesmol, citric acid, farnesenol, (E)-farnesene, octyl acetate, butyl acetate, cyanol, rutin, caryophyllene, citral, γ-terpene, linalool, acetic acid, 2-cyclopentylcyclopentanone, etc. The above substances can be used alone or in combination of multiple compounds, and used at different growth stages of the caterpillar moth to achieve the goal of luring the target pests, so as to facilitate pesticide control of pests and reduce the final yield loss. DETAILED DESCRIPTION Embodiment 1:

[0005] Prepare three compounds containing anise ketone, cis-3-hexene-1-ol and cis-β-farnesate, mix them in a ratio of 1:1:1, make an emulsifiable concentrate preparation, spray them at a dosage of 10 grams per mu of each active ingredient during the hatching period of the maggots, and use the combination to delay or postpone the time for the apple maggots to bore into the fruit, thereby increasing the probability of the insects contacting the pesticides; and use conventional chemical pesticides for pesticide application to achieve a higher mortality rate. Compared with no attractant, the prevention effect is increased by 30%. Compared with the prior art, the volatile food attractant combination for maggots on fruit trees provided by the present invention can effectively prevent and control maggots during the growth period of fruit trees, reduce the damage of maggots, reduce the amount of pesticides used, and improve the effectiveness of maggot control. Embodiment 2:

[0006] Prepare a variety of compounds including (E)-farnesene, cis-3-hexenyl, linalool, limonene, eugenol, citronellol, etc., mix them in a ratio of 1:1:1:1:1:1 to make an emulsifiable concentrate preparation, spray them at a dosage of 6 grams per mu of each active ingredient during the incubation period of the maggots, and use the combination to delay or prolong the time for the apple maggots to bore into the fruit, while using conventional chemical pesticides for pesticide application to achieve a higher mortality rate. Compared with no attractant, the prevention effect is increased by 40%. Compared with the prior art, the volatile food attractant combination for maggots on fruit trees provided by the present invention can effectively prevent and control maggots during the growth period of fruit trees, reduce the damage of maggots, reduce the amount of pesticides used, and improve the effectiveness of maggot control. Embodiment 3:

[0007] Prepare a food attractant containing 2-cyclopentylcyclopentanone by dissolving the compound in n-hexane. Use a pipette to transfer the solution to a rubber tip to make a food attractant core with 1 mg / mL of the active ingredient. Seal and refrigerate or use a white sticky board as a trap to trap male and female adults of the apple moth. Effectively reduce the number of adult moths in the orchard.
