Closed prevention and control method for longhorn beetles

Abstract

The invention discloses a closed prevention and control method for longhorn beetles. The method comprises the following steps of identifying a trunk damaged by longhorn beetles, pushing aside the soil 5 to 10cm below the root neck to find a channel of the longhorn beetle, penetrating the channel by using an iron wire, injecting organic phosphorous insecticides into the channel, coating carbofuran on and around the root neck of a seedling or a tree, and binding up the root neck by using a plastic film. By adopting the method, the effect of killing larvae of the longhorn beetle reaches 100 percent, the attack of longhorn beetles can be continuously controlled for three years, and the huge economic loss, caused by the attack of longhorn beetles, of seedlings and trees can be avoided. The method is easy to implement, and the medicines are readily available and easy to prepare and have obvious effect.

Description

technical field [0001] The invention relates to the field of prevention and control of agricultural diseases and insect pests, in particular to a closed prevention and control method for longhorn beetles. Background technique [0002] Beetles belong to the Coleoptera Beetleidae family, and they are widely distributed in my country. Some of them are more harmful to woody plants, such as the cloud-spotted longhorn beetle. Batocera horsfieldi (Hope) is a kind of serious damage to dry stem pests. Adults gnaw on the tender bark of new branches, causing the new branches to die; larvae eat and bore in the xylem of the trunk, and overwinter as larvae and adults in the borer passages and pupal chambers, forming a large number of borers. In serious cases, it will cause tree death or wind breakage, and cause significant losses to economic or ornamental seedlings. [0003] The existing long-term beetle prevention measures are mainly chemical pesticides, but for some long-term beetles ...

[0002] Beetles belong to the Coleoptera Beetleidae family, and they are widely distributed in my country. Some of them are more harmful to woody plants, such as the cloud-spotted longhorn beetle. Batocera horsfieldi (Hope) is a kind of serious damage to dry stem pests. Adults gnaw on the tender bark of new branches, causing the new branches to die; larvae eat and bore in the xylem of the trunk, and overwinter as larvae and adults in the borer passages and pupal chambers, forming a large number of borers. If it is serious, it will cause tree death or wind break, and cause great losses to economic or ornamental seedlings.

[0003] The existing long-term beetle prevention measures are mainly chemical pesticides, but for some long-term beetles whose larvae feed on the inside of the trunk, or long-term long-term long-term beetles with thick body walls and elytra, strong drug resistance, and long eclosion period , the means of chemical pesticides are difficult to achieve effective and sustainable hazard control goals
