Problems solved by technology

Light trapping is a physical control technology that uses the tendency of pests to specific light waves to artificially design light sources of different wavelengths for trapping and killing. However, this technology has the problems of killing natural enemy insects, high price, large power consumption and cumbersome maintenance.
Swatch trapping is a trapping and killing control technology designed according to the sensitivity of pests to color. It is often used in conjunction with viscose, but it still has problems such as killing natural enemies and cumbersome layout.
In addition, the color (silver film) repellent technology has defects such as high cost and limited effect.
Using specific light waves to interfere with the mating behavior of male and female tea geometrid adults, and then control the pest population related technologies have not been reported at home and abroad so far

Embodiment 1

[0034] Embodiment 1: Control of indoor population of tea geometrid by light wave interference

[0035] (1) The light wave characteristics of the test

[0036] The LED light bulb is used as the interference light source, the power of the light bulb is 3W, and the power supply is 220V AC power supply. Under the same light bulb power, the effects of light waves of different colors on the mating behavior of tea geometrid adults were compared. Six colors of light sources were set up in the experiment, namely: red (dominant wavelength 625-670nm, peak 650±5nm, light intensity 8Lux), yellow (dominant wavelength 555-610 nm, peak 590±5nm, light intensity 16Lux), green (dominant wavelength 500-565nm, peak 530±5nm, light intensity 12Lux), blue (dominant wavelength 430-490nm, peak 460±5nm, light intensity 16Lux), purple (dominant wavelength 380-420nm, peak 400±5nm, light Intensity 8Lux), white (dominant wavelength 400-670nm, peak 450±5nm, 565±5nm, light intensity 30Lux), and no light dar...

Embodiment 2

[0047] Embodiment 2: The effect of green light interference on the control of tea geometrid population in tea garden

[0048] (1) light wave for test

[0049] The field test uses LED bulbs as the interference light source, the power of the bulbs is 30W, and the power supply is 220V AC. Two colors of light sources were set up in the experiment: green (treatment light wave, dominant wavelength 500-565nm, peak 530±5nm), purple (control light wave, dominant wavelength 380-420nm, peak 400±5nm).

[0050] (2) Test method

[0051] The tea geometrid reoccurrence area in Chizhou, Anhui was selected, and the green light wave and purple light wave were used to irradiate and interfere with the tea garden at the beginning of eclosion of the fifth generation of adults (early September). The center of the bulb light source is about 0.6m higher than the top of the tea tree, the straight-line distance between the green light bulb and the purple light bulb is ≥150m, the irradiation time is fro...

Embodiment 3

[0063] (1) Test method

[0064] Green light interference method to control tea geometrid indoor press Figure 5 conduct. According to the method of Example 1, the interference effect of different green light irradiation intensities on the mating success rate of tea geometrid adults was tested. During the test, neutral filters with different transmittances were placed under the LED green light bulb to adjust the irradiation intensity.

[0065] (2) Test results

[0066] The results of the interference test showed that there were large differences in the inhibitory effects of different green light irradiation intensities on the tea geometrid population (see Image 6 ). After treatment with 10Lux green light, the mating success rate of tea geometrid was only 8%, and after treatment with 8Lux green light, the mating success rate of tea geometrid was 18%. When the irradiation intensity was 6Lux, the mating success rate of tea inchworm was 26%.

[0067] When using green light in...

Abstract

The invention discloses a physical prevention and control method for efficiently controlling population reproduction of ectropis obligue prout and belongs to the technical field of pest prevention andcontrol. According to the method, male and female ectropis obligue prout adult insects which do not mate are treated by adopting green light indoor interference for 10 h, the mating success rate of the female insects can be lowered by 90% or above, the hatching rate of egg masses can be lowered by 80% or above, the egg laying quantity of the female insects can be lowered by 40% or above, and theindoor population inhibition effect is remarkable. At the initial eclosion growth stage of ectropis obligue prout, a green light interference method is adopted for continuously conducting interferencetreatment on a tea garden for 5 nights, the inhibition rate of the offspring population of ectropis obligue prout can reach 83.5%, and the prevention and control effect can reach 86.2%. The method isused for preventing and controlling ectropis obligue prout of a tea garden, the application amount of chemical insecticide can be effectively lowered, the killing effect of a traditional light trap technology on natural enemy insects of the tea garden can be effectively lowered, and the method helps to protect the ecological environment and biodiversity of the tea garden and has good economical,social and ecological benefits.

Description

technical field [0001] The invention relates to a physical control method for efficiently controlling the population reproduction of tea geometrids, and belongs to the technical field of pest control. Background technique [0002] The damage of tea trees by pests will lead to changes in the metabolism and the composition ratio of important functional substances in the tree, which will affect the quality of tea. The warm and humid climate in my country's tea regions is also very conducive to the breeding and reproduction of various tea tree pests. According to reports, my country's annual tea production reduction due to pest damage is about 10-20%. The tea geometrid Ectropis obligueProut is one of the most economically significant leaf-eating pests on tea trees. It occurs in all tea regions in China. When it occurs seriously, it can eat all the leaves of tea trees, resulting in bare branches and stems of tea trees, destroying production and harvest. [0003] At present, the...
