Problems solved by technology

However, most of the current acaricides are chemical acaricides, which not only have many disadvantages such as few types, single action mechanism, unsatisfactory acaricidal effect, and unfriendly environment, but also easily induce drug resistance of acarids.
However, the research on biological source acaricides is currently mainly focused on plant sources and microbial sources, and there is little research on animal source acaricides. The more in-depth research is nereistoxins.

Embodiment 1

[0022] Preparation of the yellow moth powder: first place the yellow moth in an oven at 50°C to dry, then take it out, crush it, pass it through a 60-mesh sieve, and set it aside;

[0023] Preparation of the ethanol extract of the yellow hawk moth: select the sieved yellow hawk moth powder, cold-soak with 95% ethanol for 48 hours, filter to obtain the yellow hawk moth ethanol residue and the ethanol filtrate, and concentrate the ethanol filtrate to obtain the yellow hawk moth ethanol extract .

[0024] Acaricidal active composition 1: by mass percentage, it consists of 5% ethanol extract of the yellow moth, 3% hydroxypropyl methylcellulose dispersant, 2% sodium dodecylsulfonate thickener, 2% ethylene glycol antifreeze, 0.4% n-octanol defoamer, 5% CH 8 o 3 Synergist and 80% deionized water composition.

Embodiment 2

[0026] Preparation of the yellow moth powder: first place the yellow moth in an oven at 55° C., dry it, take it out, pulverize it, and pass it through a 70-mesh sieve for later use;

[0027] Preparation of Ethylacetate extract: Ethanol residue of Erythrina in Example 1 is soaked in ethyl acetate for 48h, then filtered to obtain ethyl acetate residue and ethyl acetate filtrate, and the ethyl acetate filtrate is concentrated After that, the ethyl acetate extract of the yellow moth was obtained.

[0028] Acaricidal active composition 2: by mass percentage, composed of 5% ethyl acetate extract of the yellow moth, 3% Tween 80 dispersant, 2% polyethylene glycol mono-4-nonyl ether thickener , 2% ethylene glycol antifreeze, 0.4% n-octanol defoamer, 5% Zener Wang synergist and 80% deionized water.

Embodiment 3

[0030] Preparation of the yellow moth powder: first place the yellow moth in an oven at 50-60°C for drying, take it out, pulverize it, and pass it through a 60-80 mesh sieve for later use;

[0031] Preparation of the ethanol extract of the japonica: the ethyl acetate residue of the japonica in Example 2 was soaked in ether for 48 hours, and then filtered to obtain the ether residue of the japonica and the ether filtrate, and the ether filtrate was concentrated to obtain the ether extract of the japonica .

[0032] Acaricidal active composition 3: by mass percentage, by the ether extract of 5% japonica, 3% polyvinylpyrrolidone K30 dispersant, 2% sucrose thickener, 2% ethylene glycol antifreeze, 0.4 % of n-octanol defoamer, 5% of An Rongle synergist and 80% of deionized water.

Abstract

The invention discloses a mite killing composition derived from cnidocampa flavescens and application of the mite killing composition, and belongs to the field of biological pesticides. The mite killing composition comprises the following components: 1-16% of a cnidocampa flavescens extract, 1-6% of a dispersant, 1-4% of a thickening agent, 0.5-4% of an ethylene glycol anti-freezing agent, 0.1-2%of an n-octyl alcohol defoaming agent, 2-10% of a synergist and 60-94.4% of deionized water. The mite killing composition derived from cnidocampa flavescens has a good application effect in the fieldof mite killing biological pesticide preparation and has a remarkable mite killing effect. On the one hand, the invention provides a novel animal-derived mite-killing active composition, and varietiesof mite killing substances is enriched; on the other hand, effective utilization ways of the cnidocampa flavescens are increased, and damage of the cnidocampa flavescens is reduced.

Description

technical field [0001] The invention belongs to the field of biopesticides, and in particular relates to an acaricidal composition derived from the yellow moth and its application. Background technique [0002] Cnidocampa flavescens (Walker) is an important class of leaf-eating pests. It is distributed in most parts of my country and has miscellaneous feeding habits. It mainly harms more than 120 kinds of trees such as jujube trees, pears, chestnuts, poplars, and peaches. It is an important tool for forestry development. a major hindrance. Yellow slug moths belong to the order Lepidoptera and belong to the family Limacodidae. The larvae continue to eat the leaves of trees, and can even eat up the whole sapling, which has a serious adverse effect on the normal growth and development of the host. Its occurrence is increasing year by year, and the current effective control measures are to apply pesticides to its young larvae, but once the appropriate period of control is misse...
