Embodiment 1

[0040] Indoor experiment:

[0041] Take 4 pots of Pingan tree plants planted indoors, which are respectively recorded as A, B, C and D, and placed in the laboratory, and D is used as a control group. On the leaves of the plants, 10 seven-spot ladybugs were placed in the laboratory, and the ladybug food attractant was suspended in the aphid groups of plants A, B, and C at a place 3-5cm higher than the target of action. After 24 hours of feeding, the results were investigated and tested. Repeat three times to detect the number of remaining aphids on plants A, B, C and D. As a result, there are 30±3.5 remaining aphids on plant A, 31±4.2 remaining on plant B, 30±4.5 remaining on plant C, and 96±3.2 remaining on plant D.

[0042] From Example 1, it can be seen that the ladybug food attractant of the present invention has a good attracting effect on ladybugs.

Embodiment 2

[0044] Indoor experiment:

[0045]Take 3 pots of Pingan tree plants planted indoors, and record them as A, B, and C respectively, and place them in the laboratory. Take 100 aphids raised in the room and inoculate them on the leaves of plants A, B, C, and D respectively. At ten o'clock in the morning , the control agent was configured as a solvent with a mass fraction of 0.3mmol / L, sprayed on A, B, and C plants, and the results were investigated after 24 hours of ingestion. The test was repeated three times, and the remaining aphids on A, B, C, and D plants were detected. , the result was 33±4.5 left in plant A, 34±4.1 left in plant B, 35±3.5 left in plant C, and 97±2.8 left in plant D.

[0046] It can be seen from Example 2 that the control agent of the present invention has a good control effect on aphids.

[0047] Outdoor experiment:

Embodiment 3

[0050] The first step, ecological control;

[0051] Apply biological compound fertilizer to Huangshan eucalyptus in September, control to apply once every half a month, apply 10kg per mu;

[0052] The biological compound fertilizer is prepared by mixing difluai, HYT-A strain agent and HYT-B strain agent according to the weight ratio of 1:0.2:0.3.

[0053] The second step, physical control;

[0054] In October-November, scrape the tree body of Huangshan eucalyptus and use whitening agent to whiten the trunk, backbone and large branches of Huangshan eucalyptus;

[0055] The third step is biological control;

[0056] In April, the ladybug attractant was suspended in the aphid colony at a place 3cm above the action target, and each ladybug attractant was spaced at a distance of 10cm, and the seed beetle was released in the aphid colony at the same time;

[0057] Described ladybug feed attractant comprises the following steps to make:

[0058] Step S1, add β-cyclodextrin into d...

Abstract

The invention relates to a method for removing and treating overwintering aphids of Huangshan koelreuteria paniculata. The method comprises the following steps that step 1, ecological prevention and treatment is carried out; step 2, physical prevention and treatment is carried out; step 3, biological prevention and treatment is carried out, in April, the ladybird phagostimulant is hung at the position, 3-5 cm higher than an acting target, in the aphid group, the interval between every two ladybird phagostimulant is 10 cm, and meanwhile, the seed ladle is released in the aphid group; and step 4, chemical prevention and treatment is carried out, specifically, the overwintering aphids are comprehensively prevented and treated through ecological, physical, biological and chemical prevention and treatment means, ecological prevention and treatment are carried out firstly, biological compound fertilizer is applied, and the special compound formula provides nutrition needed by planting of Huangshan koelreuteria paniculata on the one hand and can form a biological prevention and treatment and soil-borne disease mechanism on the other hand. According to the method, the use frequency of chemicals is greatly reduced, the environment is protected, and aphids are prevented from generating drug resistance due to excessive spraying frequency.

Description

technical field [0001] The invention belongs to the technical field of plant pest control, and in particular relates to a method for eliminating overwintering aphids of Huangshan eucalyptus. Background technique [0002] Aphids, also known as greasy insects and honey insects, are a class of herbivorous insects, including all members of the Aphidoidea (also known as Aphidoidea). There are about 4,400 species of aphids that have been discovered in 10 families, most of which belong to the family Aphididae. Aphids are one of the most destructive pests. About 250 of them are serious pests for agriculture, forestry and horticulture. Aphids have strong reproduction and adaptability, and conventional chemical control methods are difficult to achieve a radical effect. Moreover, the extensive use of chemical pesticides has generally produced resistance to agricultural pests. In the deep winter, aphids are in a state of hibernation and overwintering. Doing a good job in the preventi...
