Embodiment 1

[0023] Embodiment 1: a method of the present invention for preventing and controlling pine caterpillars by utilizing natural enemies to help migration + pine caterpillar virus, it is characterized in that the method is based on pine caterpillar type polyhedrosis virus oil stock solution, implemented by the following means: 1) configure virus preparation : Mix the pine caterpillar polyhedrosis virus oil solution and honey evenly at a weight ratio of 1:1; 2) Help to move natural enemies: Put the pine caterpillar cocoon in the cage, and place the virus preparation in the center of the cage.

[0024] Adopt the method of the present invention to help relocate natural enemies to prevent and control pine caterpillars, through the implementation of six plots in the Xishan forest area of ​​Mile County, Yunnan Province, and the results are shown in Table 3.

[0025]

[0026] The results prove that the method of this example is effective and has excellent effect.

Abstract

The invention belongs to the technical field of disease and pest control and particularly relates to a method for controlling dendrolimus punctatus by using artificial migration natural enemies. The method is characterized in that the method is based on a dendrolimus punctatus CPV (cytoplasmic polyhedrosis virus) oil stock solution, the dendrolimus punctatus CPV oil stock solution and a virus preparation prepared from honey are prepared and placed in a chigger cage containing dendrolimus punctatus cocoons, and thus the dendrolimus punctatus disaster is controlled. The method for controlling dendrolimus punctatus by using the migration enemies in combination with the dendrolimus punctatus virus has the technical advantages of quick and good dendrolimus punctatus control effect.

Description

technical field [0001] The invention belongs to the technical field of pest control, in particular to a method for preventing and controlling pine caterpillars by using artificial relocation of natural enemies. Background technique [0002] Pine caterpillar is a collective name for insects belonging to the genus Pine caterpillar of Lepidoptera, also known as caterpillars, fire caterpillars, and anciently known as pine silkworms. The common pine caterpillars in Yunnan are Simao pine caterpillars and Wenshan pine caterpillars, which generally cause Yunnan pine to die when the needles are eaten up in 2-3 years; pine trees that are not eaten up will also cause tree vigor to weaken, and the physiological and biochemical indicators of the pine tree itself Decreased turpentine secretion and resistance, coupled with frequent human activities in the forest, improper use of pine caterpillars, such as extensive use of pesticides, resulting in the death of a large number of natural enem...
