Problems solved by technology

[0004] Due to the long life cycle of the pink-necked beetle and its strong concealment when injuring host plants, except adults, other insect stages (larvae, pupae) are spent in the trunk, which brings great difficulties to the control.
The existing chemical control methods are not only ineffective, but also cause environmental pollution, so there is an urgent need to study new biological control methods

Embodiment 1

[0019] Example 1 Indoor use of the Chinese beetle cat mite combined with bio-control bacteria to control the middle and young larvae of the pink-necked longhorn beetle

[0020] 1 test material

[0021] 1.1 Insect source: the Chinese beetle (hereinafter referred to as the veterinarian) was provided by the Natural Enemy Breeding Center of the Changli Fruit Tree Research Institute of the Academy of Agriculture and Forestry of Hebei Province; In peach trees, the larvae whose body length is 2-3cm (middle age) are used as test insects.

[0022] 1.2 Bio-control bacteria: Bio-control bacteria spore powder (Metarhizium anisopliae) was provided by Chongqing Julixin Biological Engineering Co., Ltd.

[0023] 2 test method

[0024] 2.1 Treatment of cat mites carrying biocontrol bacteria

[0025] Sprinkle 0.1g of biocontrol fungus spore powder into a 12cm-diameter petri dish, shake it evenly and pour out the excess spore powder, put the propagule that has started to produce offspring for...

Embodiment 2

[0032] Example 2 Field Utilization of the Chinese Beetle Papyrus mite to Control Peach-necked Longhorn Beetle Young Larvae

[0033] 1 test material

[0034] 1.1 Insect source: The Chinese beetle, the catfish, was provided by the Natural Enemy Breeding Center of Changli Fruit Tree Research Institute, Hebei Academy of Agriculture and Forestry Sciences.

[0035] 2 test method

[0036] 2.1 Release time

[0037] On May 15, 2019, it was released in the cherry orchard in Shanhaiguan, and in Taoyuan, Changli County on September 1.

[0038] 2.2 release method

[0039] Before release, select cherry trees and peach trees that have been infested by the pink-necked longhorn beetle, with a DBH of 20-25 cm, and mark the small dung holes. Use the conventional product of the Chinese beetle nymph alone to release once, and the release amount is set in 3 gradients, which are 1 box of nymph per plant (100,000 heads), 2 boxes of nymph per plant (200,000 heads), and 3 boxes of nymph per plant ...

Abstract

The invention provides a biological control method of aromia bungii. Pyemotes zhonghuajia and biocontrol bacteria are combined for use in a middle-and-low-age larva stage of aromia bungii. According to the method, pyemotes zhonghuajia and biocontrol bacteria are combined for biological control on aromia bungii, a good control effect, 80% or above, can be achieved under the condition that the release amount of pyemotes zhonghuajia is low, aromia bungii can be killed more quickly and effectively before causing severe damage, so that the tree vigor can be restored rapidly. Moreover, the biological control method greatly reduces the use amount of pesticide, reduces environmental pollution, and guarantees safe and sustainable development of the ecological system.

Description

technical field [0001] The invention relates to the field of biological control of pests, and more specifically, to a biological control method of longhorn beetle. Background technique [0002] The pink-necked longhorn beetle (Aromia bungii Fald), also known as the red-necked longhorn beetle, is commonly known as the iron cannon insect, and belongs to the family Cerambycidae of the order Coleoptera. It is native to East Asia and is distributed abroad in the Korean Peninsula, Vietnam and Russia. In 2013, it was reported that it had settled in Germany and Italy, and the United States and the United Kingdom had also intercepted the insect, which attracted great attention from the two countries. British scientists also conducted a risk assessment of its hazards. It is widely distributed in my country except Xinjiang and Tibet and other high-altitude severe cold regions. It is reported that it mainly damages stone fruit trees such as peach Amygdaluspersica, cherry Cerasus pseud...
