Problems solved by technology

However, due to the long life history of the longhorn beetle, its eggs, larvae and pupae all live in the trunk, the individuals are scattered, live alone, and are rarely affected by external adverse conditions, so the control effect is not ideal.
At the same time, ash trees are generally used as garden or urban greening trees. The use of a large number of chemical pesticides will undoubtedly pollute the ecology and human settlements and lack sustainability, which is contrary to the purpose of people's cultivation of ash trees to improve the environment.

Embodiment 1

[0029] A method for biological control of tree beetles, comprising the following steps:

[0030] S1, determine the growth state of longhorn beetles on trees: the growth state includes larval stage, pupal stage and adult eclosion stage;

[0031] The number of larvae was recorded through the defecation holes. Many longhorn beetle larvae continuously excreted the feces out of the trunk through the defecation holes during the feeding process. The number of defecation holes can reflect the number of insect populations in the damaged wood to a certain extent.

[0032] The judgment of the pupal stage adopts methods such as cutting bark in the prior art and all can.

[0033] The adult eclosion exit stage can be judged by observing the number of eclosion holes.

[0034] S2, applying the longicorn larva control agent at the larvae stage, applying the longicorn beetle pupa stage control agent at the pupa stage, and applying the longicorn beetle adult control agent at the adult eclosion ...

Embodiment 2

[0045] A method for biological control of tree beetles, comprising the following steps:

[0046] S1, determining the growth state of longhorn beetles on trees: the growth state includes larval stage, pupal stage and adult emergence stage; the judgment of each stage is the same as that in Example 1.

[0047] S2, applying the longicorn larva control agent at the larvae stage, applying the longicorn beetle pupa stage control agent at the pupa stage, and applying the longicorn beetle adult control agent at the adult eclosion stage to complete the control of the tree longicorn beetle;

[0048] The long-beetle larva control agent is made of the following components by weight: 80 parts of Beauveria bassiana spore liquid, 10 parts of Toosendan bark soaking juice, 2 parts of absolute ethanol, and 1 part of emulsifier; the emulsifier is glycerin ; The method for controlling long beetle larvae is prepared and preserved according to Example 1.

[0049] The long-beetle pupal stage control...

Embodiment 3

[0058] A method for biological control of tree beetles, comprising the following steps:

[0059] S1, determining the growth state of longhorn beetles on trees: the growth state includes larval stage, pupal stage and adult emergence stage; the judgment of each stage is the same as that in Example 1.

[0060] S2, applying the longicorn larva control agent at the larvae stage, applying the longicorn beetle pupa stage control agent at the pupa stage, and applying the longicorn beetle adult control agent at the adult eclosion stage to complete the control of the tree longicorn beetle;

[0061] The long-beetle larva control agent is made of the following components by weight: 60 parts of Beauveria bassiana spore liquid, 20 parts of Toosendan bark soaking juice, 1 part of absolute ethanol, and 0.5 part of emulsifier; the emulsifier is Tray 80; the longicorn larva control agent is prepared and preserved according to the method in Example 1.

[0062] The control agent for the pupal st...

Abstract

The invention belongs to the technical field of longhorn beetle control and specifically discloses a biological control method of longhorn beetles on trees. The method comprises following steps: applying longhorn beetle larva control agent in the larva stage; applying longhorn beetle pupa control agent in the pupa stage; applying longhorn beetle imago control agent in the imago eclosion hole stage; in this way, the control of longhorn beetles on trees is completed; the longhorn beetle larva control agent is prepared from beauveria bassiana spore liquid, Sichuan azedarach extract, ethanol, and emulsifier; the longhorn beetle pupa control agent is prepared from beauveria bassiana spore liquid, adonis aestivalis extract and ethanol; the longhorn beetle imago control agent is prepared from beauveria bassiana spore liquid, hydrogen peroxide, ethanol and adonis aestivalis extract. According to the method of the invention, beauveria bassiana spore liquid is adopted as biological source for controlling longhorn beetles and the application of toxic chemical pesticides such as zinc phosphide and aluminum phosphide is avoided to reduce environment pollution and protect the ecological environment.

Description

technical field [0001] The invention belongs to the technical field of longicorn beetle prevention and control, and in particular relates to a biological control method for tree longicorn beetle. Background technique [0002] The multi-spotted white beetle (Batocera horsfieldi Hope) mainly harms paulownia, apple, pear, paraffin, elm, walnut and other trees. Because the ash tree has strong adsorption capacity and resistance to pollutants such as sulfur dioxide, chlorine gas, hydrogen chloride and smoke dust, it is one of the important landscaping tree species in my country. In recent years, the harm and occurrence of the multi-spotted long beetle has become more and more serious. It has flooded many places, causing a large number of deaths or poor growth and dying, causing huge losses to the ecological environment and urban greening. It has become an urban forestry, It is a major pest in landscaping and ecological city construction and development. [0003] At present, chem...
