Description

{Method of eco-friendly controlling brown wings leaf hoppers}

The present invention relates to an eco-friendly control method of brown winged flies for effective enticing and trapping by combining an eco-friendly attractant made of vegetable essential oil and ethanol and a yellow plate-type adhesive trap for eco-friendly control of a type of forest pest. it's about

The brown-winged leafhopper is an insect of the order Hemiptera that inhabits mainly in Southeast Asia. It is classified as a pest that attaches to the stem of trees or grass, sucks the sap, and spawns on the branches of young one-year-old trees, causing damage to fruit trees and forests.

The body length of the adult insect is 8mm and the wingspan is about 15mm. The overall color is dark brown, and there is a wavy pattern in the center of the wing. The body length of the nymph released from the egg is about 4.5 mm. The brown-winged nymph nymph has a white waxy substance, which gradually increases as it grows. The yellowish white waxy substance gives it an overall whitish appearance and is easy to find on tree or grass trunks.

The brown-winged leafhopper occurs once a year. After spending the winter as an egg, it hatches around May and spends a period of time as a nymph. The nymphs attach to the young stems of plants, suck the sap, and secrete a white waxy substance to attach to the stems, which causes soot disease on fruits, leaves, and stems. During the nymph period, they eat more sap than adults, and they molt 4 times before becoming an adult. The brown-winged hawthorn caterpillar, which became an adult around mid-July, lays eggs in the branches from mid-August. It spawns mainly on first-year young branches, which can damage the growth of trees.

The brown-winged flycatcher has a wide range of host plants used as food, such as fruit trees, crops, grasses, and broadleaf trees, and there are cases where it inhabits forests, orchards, farmland, as well as residential areas. They generally prefer dark environments and are difficult to control due to their wide habitat.

From mid-August to before May, control by removing or sealing the branches that laid eggs. The brown winged flycatcher lays eggs in the tissue rather than the outer surface of the branch, so it is difficult to control if the area is not removed. From mid-July to mid-August when adults appear, sticky traps are used to prevent spawning. Yellow sticky traps are installed at intervals of about 3 m, and a height of 1 to 1.5 m is suitable. The reason for using yellow is to increase the inflow effect. In particular, from the end of August, there are many cases of adult brown-winged hoppers entering orchards from the mountains, so it is necessary to thoroughly control them.

Representatively, the severely damaged orchards damage major fruit trees in Korea such as apples, blueberries, peaches, sweet persimmons, cornflowers, and jujubes. In this way, to prevent the damage of the brown-winged leafhopper, which damages major fruit trees in Korea, insecticides are mainly used on farms to catch the brown-winged leafhopper. , pesticides remain on fruits and orchards due to pesticide spraying, causing secondary damage.

Brown-winged flycatcher likes light at night, so you can lure it with a baby light to catch it. In Patent Document 1, when a sticky trap plate fixed under an LED light is hung and the LED light is emitted, a technique is proposed in which pests are attracted to fly and stick to the sticky trap and die. However, in the above registered utility model, it is difficult to attract pests from far away due to its structure, and once a layer of brown winged cicadas adheres to the periphery of the sticky trap plate, it does not adhere thereafter. , there is a problem that the price of the sticky trap plate, which cannot be recycled, is high, and thus it is not economical.

In Patent Document 2, a housing constituting the body, a long-distance attractor that emits ultraviolet light to attract pests from a distance, and a short-range attractor that emits an attractor to re-attract pests attracted to a short distance by the remote attractor and a caterpillar that kills pests attracted to the inside of the housing by the long-distance attractor and the short-distance attractor by falling into a trapping tank provided at the lower part of the housing to die. Since the size of the drawer-type trapping tank provided in the tank is small and the effect is lost as the pests do not fall into the tank over time, there is a problem in that the trapping device must always be managed by the side because it must be emptied when the collecting tank is filled with pests to some extent.

In Patent Document 3, brown-winged flycatchers are lured in a wide area with long-distance entrenched infants and short-distance entrenched infants, etc. to be rescued using a capture tank, and even if there is no manager, the brown-winged flycatcher is automatically removed, and the insufficient water in the capture tank is replenished. Although a device for attracting and trapping brown-winged larvae has been proposed, there is a problem in that the number of individuals that fall due to a collision and fall into the tank is small, so that the capture effect is poor despite successful attracting.

Korea Registered Utility No. 20-0457870 (Registered on Jan. 2, 2012) Korean Patent Registration No. 10-1032713 (Registered on April 26, 2011) Korean Patent No. 10-1944951 (registered on February 28, 2019)
