Problems solved by technology

Some worms can parasitize in the crevices, scars or root soil of willow trees. They use needles to suck into the phloem of the trunk to absorb the nutrients of willow trees. On the trunk, there are generally ant tunnels built by symbiotic ants with soil. The willow beaked aphid lives directly hidden in the soil, avoiding the predation of natural enemies of aphids such as ladybugs, lacewings, hoverflies and other insects, and at the same time it is more difficult to infect insect pathogens, and it is difficult to use pesticides to control it. Prevention and treatment is extremely difficult

Embodiment 1

[0015] A method of using ants to spread Verticillium laxacilis to prevent and control tree trunk hidden willow beaked aphids, comprising the following steps:

[0016] (1) Prepare Verticillium lecanii spore powder, which can be obtained through purchase or solid fermentation culture;

[0017] (2) Prepare the brown sugar lard block first melt the lard, slowly add the brown sugar to melt, stir gently, so that the brown sugar content accounts for 5%, cool and condense to make brown sugar lard block, cut the brown sugar lard block into 2cm 3 Small square pieces, refrigerated at 4°C for later use;

[0018] (3) Roll the brown sugar lard cubes cut into small pieces in the Verticillium lecanii spore powder, so that the surface is covered with the spore powder, and make the release block of Verticillium lecanii spores;

[0019] (4) Place the release block of Verticillium lecanii spores around willow trees with ant tunnels in the trunk, at the ant tunnel openings and ant nest openings ...

Embodiment 2

[0021] A method of using ants to spread Verticillium laxacilis to prevent and control tree trunk hidden willow beaked aphids, comprising the following steps:

[0022] (1) Prepare Verticillium lecanii spore powder, which can be obtained through purchase or solid fermentation culture;

[0023] (2) Prepare the brown sugar lard block first melt the lard, slowly add brown sugar to melt, stir gently to make the brown sugar content account for 30%, cool and condense to make brown sugar lard block, cut the brown sugar lard block into 0.5cm 3 Small square pieces, refrigerated at 4°C for later use;

[0024] (3) Roll the brown sugar lard cubes cut into small pieces in the Verticillium lecanii spore powder, so that the surface is covered with the spore powder, and make the release block of Verticillium lecanii spores;

[0025] (4) Place the release block of Verticillium lecanii spores around willow trees with ant tunnels in the trunk, at the ant tunnel openings and ant nest openings of ...

Embodiment 3

[0027] A method of using ants to spread Verticillium laxacilis to prevent and control tree trunk hidden willow beaked aphids, comprising the following steps:

[0028] (1) Prepare Verticillium lecanii spore powder, which can be obtained through purchase or solid fermentation culture;

[0029] (2) Prepare the brown sugar lard block first melt the lard, slowly add brown sugar to melt, stir gently to make the brown sugar content account for 15%, cool and condense to make brown sugar lard block, cut the brown sugar lard block into 1cm 3 Small square pieces, refrigerated at 4°C for later use;

[0030] (3) Roll the brown sugar lard cubes cut into small pieces in the Verticillium lecanii spore powder, so that the surface is covered with the spore powder, and make the release block of Verticillium lecanii spores;

Abstract

The invention discloses a method using ants to spread verticillium lecanii for control of tree trunk stomaphissinisalicis; first, a lard and brown sugar mixture with the sugar content about 5-30% is prepared, after the lard and brown sugar mixture is condensed into a bulk, the lard and brown sugar mixture is cut into 0.5-2cm<3> small pieces, the small pieces are rolled in verticillium lecanii spore powder, so that the surface of the small pieces is fully covered with verticillium lecanii spore, and a verticillium lecanii spore release block is prepared; the verticillium lecanii spore release block is put in an inlet of an ant nest and an inlet of an ant path of a tree trunk for freely feeding to the ants, in the free feeding process, the verticillium lecanii spore may stick to epidermis, mouthparts and limbs, when the verticillium lecanii spore contacts stomaphissinisalicis hiding in the tree trunk, the verticillium lecanii spore may be transferred to the stomaphissinisalicis, and after the stomaphissinisalicis body surface is infected by the verticillium lecanii spore, the stomaphissinisalicis may die due to infection. The method has the advantages of good control effect, low cost and environmental protection.

Description

technical field [0001] The invention belongs to the field of biological technology, and relates to a method of using ants to spread Verticillium lecanii Pandora neoaphidis Prevention and Control of Trunk Willow Long-beaked Aphid Stomaphis sinisalisis Methods. Background technique [0002] Willow long beak aphid is an important willow pest, mainly harming many kinds of willows such as white willow, hairy willow, weeping willow, firecracker willow, Qinggang willow, smooth willow and Korean willow. The aphid has more than 10 generations a year and overwinters as adults in the bark crevices at the lower part of the trunk. In the spring of the following year, it begins to move upwards, and it breeds in large numbers from April to May, causing disasters. When a large number occurs, the secreted honeydew is like light rain, and there is a layer of brown mucus on the ground. Nymphs and adults cluster on young branches and twigs, suck branch sap, and secrete honeydew, often caus...
