Problems solved by technology

Thrips and Bemisia tabaci suck and damage plants, and compete with cotton aphids for nutrients, causing adverse effects on plants
Parasitic wasps parasitize aphids, and the population of aphids decreases rapidly, affecting the continued proliferation of aphids, and in severe cases, causing the population of aphids to collapse
[0004] During the breeding process of aphid populations, it is inevitable that they will be polluted by insects such as thrips, whitefly or their natural enemies, parasitoids. Simply relying on chemical pesticides to remove pollution is not conducive to the growth of aphids, and relying on manual repurification is time-consuming and laborious

Embodiment 1

[0029] The present embodiment relates to the removal of thrips in aphids, comprising the steps of:

[0030] Soak the leaves with aphids and thrips or the composition of host plants or plant stems and leaves in 0.1% ethyl allicin aqueous solution, soak for 5 seconds each time, and soak 5 times; until the thrips are removed from the leaves, host plants or plants The composition of stems and leaves falls off, and finally soaked in clean water for 2 times, each time for 3s. By adopting the method for deworming, the removal rate of thrips can reach more than 95%. The unremoved part is the thrips hidden in the axillary buds of cotton, which are not easy to remove. If you increase the number of times of soaking, it can be cleaned up, and the removal rate can reach 100%.

Embodiment 2

[0032] The present embodiment relates to the removal of thrips in aphids, comprising the steps of:

[0033] Soak the leaves with aphids and thrips or the composition of host plants or plant stems and leaves in 0.2% acetoallicin aqueous solution, soaking for 5 seconds each time, soaking 3 times; until all or part of the thrips are removed from the leaves or The host plant or the composition of plant stems and leaves falls off, falls into water, and finally soaks in clean water for 1-2 times, each time for 3-5s. By adopting the method for deworming, the removal rate of thrips can reach more than 95%. The unremoved part is the thrips hidden in the axillary buds of cotton, which are not easy to remove. If you increase the number of times of soaking, it can be cleaned up, and the removal rate can reach 100%.

Embodiment 3

[0035] Present embodiment relates to the removal of bemisia tabaci in aphids, comprises the steps:

[0036] Soak the leaves of aphids and Bemisia tabaci or the composition of host plants or plant stems and leaves in an aqueous solution containing acetoallin, the concentration of the aqueous solution of acetoallin is 0.05%, soak for 10 seconds each time, 5 times, and finally Soak in clean water once for 3 seconds. After washing with clean water, the residue of acetoallicin is reduced and the impact on aphids is reduced. By adopting the method for deworming, the removal rate of Bemisia tabaci can reach more than 95%.

Abstract

The invention relates to application of ethylicin in removal of polluting insects from aphids. The application comprises the following steps: preparing ethylicin into an aqueous solution of ethylicin,and soaking or spraying leaves, plants or plant stems or leaves infected with aphids and polluting insects. The invention first provides a method for separating the aphids from the polluting insectsby utilizing sensibility differences of the aphids and polluting insects on the ethylicin. The method is capable of rapidly removing pollution of thrips, bemisia tabaci or parasitic wasps and the likeand has significances on purification and propagation of the aphids.

Description

technical field [0001] The invention belongs to the field of pest control, and in particular relates to the application of acetoallicin in removing polluting insects from aphids. Background technique [0002] Aphids, also known as greasy insects and honey insects, are an important class of agricultural, forestry and horticultural pests. There are many kinds of aphids, a wide range of hosts, and a large number. Adults and nymphs often gather on the young leaves, stems and leaf backs of vegetable plants to suck plant juice. , resulting in poor plant growth and short plants, seriously affecting crop yield and quality. As a typical piercing-sucking insect, aphids are not only small in size and soft in body surface, but also have the characteristics of parthenogenesis, fast growth and reproduction, and overlapping generations. It is also an important research object in the control of agricultural pests. [0003] Aphids are often studied indoors on potted plants or on hydroponi...
