Description

Method for preventing and controlling grape leaf miner based on push-pull principle

Technical Field

The invention relates to a pest control method, in particular to a method for controlling grape fruit-fin moth.

Background

The grape fruit penetrating moth is a borer commonly occurring in grape planting areas, and borers on the stem pulp of new tips or old branches of grapes are borerd by larvae, so that leaves become yellow, flowers fall and fruits fall, even branches and vines are hollow and withered, the yield of grapes is reduced, and economic loss is brought to fruit growers. The grape fruit moth overwinter in branches and tendrils with old larva, so the larva control mainly uses winter pruning branch control. And the imagoes begin to appear and lay eggs every 5-6 months, the imagoes are used as the only insect states which can move outside the plant, and the key of prevention and control is that the imagoes are trapped to interfere with the laying eggs.

CN105028042A discloses a method for controlling grape fruit-fin moth. The literature "common species and hazard characteristics of the paranthrene moth and green prevention and control technology" (Wangzhonglin, scientific culture, 2020(11):36-38.) also discloses a method for preventing and controlling the paranthrene moth. The prior art methods all utilize a method for comprehensively treating pests to prevent and control the grape leaf miners, and comprise the steps of agriculturally trimming damaged branches and tendrils to destroy overwintering insect sources, reasonably applying fertilizer to enhance soil fertility, and utilizing phototaxis of imagoes to carry out physical prevention and control of light trapping and killing, wherein the biological prevention and control method comprises the steps of protecting and utilizing natural enemies, spraying microbial preparations and setting sex attractant for trapping and killing, and spraying chemical insecticides at different periods. CN105028042A highlights that the disease of grape fruit through moth can be prevented by improving soil structure and biological colony through the microbial fertilizer used by the compound. The prior art recommends using phototaxis of the paranthrene to adopt a light trapping method to prevent and control the paranthrene but the prevention and control effect is not ideal.

Disclosure of Invention

The inventor researches and discovers that the trap lamp mainly using the common ultraviolet light has no trapping effect on grape fruit moth, but grape fruit moth imagoes have an evasion function on the trap lamp, and further provides the invention.

A method for preventing and treating grape fruit moth based on push-pull principle includes using trap lamp to repel grape fruit moth.

Specifically, the light wavelength of the trap lamp is 320-360 nm.

In particular, the power of the trap lamp is 15-40W, for example 15W.

Specifically, the trap lamp is a frequency vibration type trap lamp.

Specifically, the trap lamp is arranged inside and/or at the periphery of the vineyard. Further, the height of the trap lamp is 20-30cm higher than the top of the grape plant. Therefore, the repelling effect on the grape paranthrene tabaniformis is better.

Specifically, at least one trap lamp is arranged inside the vineyard.

Specifically, the method for controlling the paranthrene tabaniformis further comprises the step of placing a sex attractant at the periphery of the vineyard to attract the paranthrene tabaniformis. Further, the sex attractant is placed at the position 2-3 meters away from the periphery of the vineyard.

Specifically, the method for controlling the grape paranthrene tabaniformis further comprises the step of placing the sex attractant in the vineyard so as to monitor the population dynamics of the grape paranthrene tabaniformis inside and outside the vineyard. And when the paranthrene tabaniformis is detected in the vineyard, the trap lamp is turned on to drive the paranthrene tabaniformis out of the vineyard.

Specifically, the sex attractant comprises sex pheromone of grape paranthrene. The sex attractant is commercially available.

Specifically, the method for controlling the grape fruit-fin moth further comprises the step of arranging the trap lamp at the periphery of the vineyard. When the paranthrene tabaniformis is not detected in the vineyard, the trap lamps at the periphery of the vineyard can be turned on to prevent the paranthrene tabaniformis from entering the vineyard. Further, 1 trap lamp can be arranged at every 100m on the periphery of the vineyard. Therefore, the protective net can be formed to drive adult grape leaf moths and trap other phototaxis grape pests.

Specifically, the method for controlling the grape fruit tree moth further comprises the steps of paying attention to observe and remove harmful branches and tendrils when fruit branches are trimmed in winter, and intensively destroying and killing overwintering larvae.

In some embodiments, the method of control of grapevine paranthrene further comprises:

placing a sex attractant at a position 2 meters away from the periphery of a vineyard and at the center of the orchard, and monitoring the population dynamics of the paranthrene tabaniformis inside and outside the orchard;

1 trapping point suspension frequency vibration type trap lamps are arranged at intervals of 100m on the periphery of a vineyard, and 1 trap lamp is suspended at the central position of the orchard; when the grape garden does not have the grape paranthrene, or the sex attractant core does not trap the grape paranthrene, only the peripheral trap lamp of the grape garden is turned on to form a protective net to drive the adult grape paranthrene, and simultaneously trap other phototaxis grape pests;

when it is monitored that the grape winged moth or the orchard has the winged moth damage, turning off the trap lamps at the periphery of the vineyard, turning on the trap lamps at the central position of the vineyard, and driving the adult grape winged moth to the periphery of the orchard;

placing a sex attractant at the periphery of the vineyard to trap adult grape leaf miners flying to the periphery of the orchard;

when fruit branches are pruned in winter, attention is paid to observe and remove harmful branches and tendrils, and overwintering larvae are intensively destroyed and killed.

Insects, particularly lepidopteran insects, are generally considered to have a phototactic habit by which they can be controlled using insect luring lamps. The inventor researches and discovers that the trap lamp mainly using the common ultraviolet light has no trapping effect on grape fruit moth, but the grape fruit moth imago has an evasive function on the trap lamp. Based on the discovery, the invention utilizes the push-pull effect principle, drives pests in the orchard out of the orchard by using light, and then traps the pests by using the sex attractant. Thus effectively improving the control effect on the grape paranthrene tabaniformis. In an orchard where no grape paranthrene tabaci occurs, population monitoring is carried out by adopting a sex attractant trapping method, and meanwhile, trap lamps are arranged on the periphery of the orchard by utilizing the avoiding effect of imagoes on light to drive the grape paranthaci tabaci imagoes to enter the orchard. In an orchard endangered by the paranthrene tabaci, the arrangement positions of the trap lamps and the sex attractant are reasonably distributed in the orchard by utilizing the tropism of the adult grape paranthaci to the sex attractant and the avoidance of light, the trap lamps are placed in the orchard to drive the grape paranthaci, the sex attractant is placed at the periphery of the orchard to trap the adult grape paranthaci, and therefore the control effect on the grape paranthaci can be better improved. The method utilizes the habit of the grape fruit moth, reasonably matches the use attractant and the trap lamp, and obviously improves the control effect of the grape fruit moth.

Detailed Description

The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

The frequency-vibrating insect trap lamp used in the following is purchased from Aurea pest control science and technology Limited, Shenzhen, model JH-D330/D, and the power is 15W.

The sex attractant used below is grape Perpeta xylostella sex pheromone. Sex attractants were purchased from beijing zhongji four-party biotechnology, inc.

Example 1

1) And (3) placing a sex attractant at a position 2 meters away from the periphery of the orchard and at the center of the orchard, and monitoring the population dynamics of the grape fruit moth inside and outside the orchard.

2) And turning on a trap lamp at the periphery of the orchard to repel the grape winged moth imagoes and trap other phototaxis grape pests.

Example 2

1) When the damages of the paranthrene tabaniformis occur in the orchard, the trap lamp in the center of the orchard is turned on, and adult grape paranthrene tabaniformis in the orchard are driven to the periphery of the orchard.

2) Meanwhile, a sex attractant is placed at the periphery of the orchard garden to trap the grape paranthrene imago flying to the periphery of the orchard garden.

3) When the fruit branches are pruned in winter, the damaged branches and tendrils are observed and removed, and the overwintering larvae are destroyed intensively.

Test example 1

In 7-9 months in 2019, 1 frequency-vibrating insect attracting lamp is hung every 100m in a vineyard (known to have the grape piercing moth pests) in the coast of Wenling mountains city of Zhejiang, the insect attracting lamp is 20cm higher than a grape plant, and the number of grape piercing moths and other lepidoptera insects caught by the insect attracting lamp is investigated every 4 days or so. As a result, as shown in Table 1, the trap lamp can trap a large number of prodenia litura and other lepidoptera pests, and the number of the trapped grapevine paranthrene pests is 0. Therefore, the trap lamp mainly based on ultraviolet light commonly used in the market at present has no trapping effect on the grape fruit moth.

TABLE 1 number of Lepidoptera pests such as grape paranthrene induced by trap lamp

Note: the data in Table 1 are the average number of pests attracted by each frequency-vibrating insect trap.

Test example 2

In 2019, from 8 months and 4 days to 10 months and 15 days, the following experiments are respectively carried out on 3 independent grapevines in coastal towns in Wen Ling of Zhejiang, and the management conditions are consistent (the area of each grapevine is 25 mu):

treatment 1 (trap lamp): frequency vibration type trap lamps are arranged at 2 meters of the periphery of the orchard, and one trap lamp is arranged about every 100 meters to trap the grape leaf miners.

Treatment 2 (sex attractant): traps (in which sex attractants are placed) are placed in the orchard. The spacing of each trap is 100 meters.

Treatment 3 (trap lamp + sex pheromone): a frequency vibration type trap lamp (the height of the trap lamp is 20-30cm higher than the top of a grape plant) is placed in the center of the orchard, and a trap (in which sex attractant is placed) is placed on the trap lamp. The trap lamp and the trap are used as a set of trapping device. The distance between each set of trapping device is 100 meters.

Investigating adult grape leaf miners caught by the trap lamp or the sex attractant every 4 days or so. The results are shown in Table 2. The results show that the number of adult grape fruit moth (Perkinra) lured by the trap lamp of the treatment 1 is 0, the number of adult grape fruit moth lured by the sex attractant of the treatment 2 is the largest, and the number of adult grape fruit moth lured by the sex attractant of the treatment 3 when the trap lamp and the sex attractant are put together is lower than that of the trap of the sex attractant of the treatment 2 alone. Therefore, the grape paranthrene adult insect can be inferred to have the evasion function to the trap lamp, and the sex attractant has stronger trapping and collecting functions to the adult insect. Therefore, by reasonably utilizing the push-pull effect principle, the pests in the orchard are driven out of the orchard by the light and then trapped by the sex attractant, and the control effect on the grape fruit moth can be effectively improved.
