AI Technical Summary

Problems solved by technology

At present, the methods of preventing and controlling such pests generally include (1) biological control and engineering control: screening and utilizing parasitic and predatory natural enemy resources, such as parasitic wasps, velvet beetles, woodpeckers, etc., to achieve biological control; For forest defense against longicorns, engineering control technologies such as grafting of insect-resistant poplar varieties and high-efficiency longicorn lures are adopted. This method is undoubtedly expensive and not easy to see a good control effect in a short period of time; (2) using fungi, bacteria At present, this method of prevention and control is becoming more and more mature, but the conditions of use are relatively harsh and the cost is relatively high; (3) popularize the application of high-efficiency insecticides, this method has the fastest effect, but often focuses on For "cure" rather than "prevention"
Moreover, longhorn beetles are hidden, and the timing of using insecticides is very difficult to grasp.

Effect test

Embodiment 1

[0009] Embodiment 1 (Jingzhou, Hubei), adopts the weight percent of following each component to be:

[0010] Camphor (2-camphorone) 1%, fresh leaves of camphor tree 99%

[0011] The preparation of a repellent comprises the following steps: firstly, grinding camphor into powder; secondly, chopping fresh camphor leaves; and thirdly, mixing camphor powder with crushed leaves to obtain a repellant. Then the repellant is buried in the base of poplar, and the control effect is 95%.

Embodiment 2

[0012] Embodiment 2 (Qichun, Hubei), adopts the weight percentage of following each component to be:

[0013] Camphor (2-camphorone) 0.6%, fresh leaves of camphor tree 99.4%

[0014] The preparation method is the same as in Example 1. The repellant is buried in the base of mulberry tree, and the control effect is 97%.

Embodiment 3

[0015] Embodiment 3 (Lujiang, Anhui), the percentage by weight that adopts following each component is:

[0016] Camphor (2-camphorone) 0.7%, fresh leaves of camphor tree 99.3%

[0017] The preparation method is the same as in Example 1. The repellant is buried in the base of the peach tree, and the control effect is 94%.

Abstract

Disclosed is an insectifuge and its preparation method, wherein the insecctifuge mixed from camphor and fresh leaves of camphor tree, the preparation process comprises polishing the camphor into powdery form, chopping the fresh leaves, and finally mixing the two components.

Description

technical field [0001] The present invention relates to a pest repellent, more specifically to a repellant, and also to a preparation method of the repellant. Background technique [0002] Long beetle stem borer pests feed on the phloem and xylem of the trunk as larvae, destroying the tree's transport tissue and causing tree death. It is difficult to be found because of its hidden damage. As far as the important tree species poplar in the main ecological protection forests and economic timber forests in my country are concerned, the species that cause serious damage include the long-shouldered longhorn beetle, the yellow-spotted long-beetle beetle, the long-spotted long-beetle beetle, the long-spotted long-beetle beetle, etc. Very serious. At present, the methods for preventing and controlling such pests generally include (1) biological control and engineering control: screening and utilizing parasitic and predatory natural enemy resources, such as paras...
