Problems solved by technology

After eating by aphids, the tobacco leaves shrink and become thinner, and the severely damaged plants grow slowly, are prone to soot, and are brittle and lack luster after roasting. The cigarettes made are not good and have poor combustion properties.
And aphids can also spread a variety of viral diseases, such as cucumber mosaic virus (CMV), potato virus Y (PVY), tobacco vein mottle virus (TVMV), tobacco vein band mosaic virus (TvBMV), etc., to the production of tobacco. cause huge losses
In the past, chemical insecticides were mainly used to prevent and control aphids. During the period of aphids, farmers usually increased the amount of pesticides used and the frequency of spraying to reduce the number of aphids, but at the same time caused the death of a large number of natural enemies of field pests. , pesticide residues, which not only destroy the ecological balance but also threaten human health

Abstract

The invention discloses an attractant for aphids and a preparation method thereof. The attractant for aphids uses liquid paraffin as a solvent, and the volume fraction is 0.1 to 1%. α -Phellandrene solution, cis-3-hexenol solution, methyl jasmonate solution and octanol solution are mixed in equal proportions. The attractant is a specific component screened from plant volatile substances, and has the characteristics of high selectivity and strong pertinence. The attractant can lure the aphid, and is of great significance for reducing the harm of the aphid to tobacco, reducing tobacco virus diseases, and the like.

Description

technical field [0001] The invention belongs to the technical field of biological control of tobacco pests, and in particular relates to an attractant for tobacco aphids and a preparation method thereof. Background technique [0002] tobacco( Nicotiana tabacum ) belongs to the annual herbaceous plant of Solanaceae, and is an important economic crop in my country. Aphids Myzuspersicae (Sulzer) is one of the important pests on tobacco, causing harm in the seedling and field stages of tobacco. After eating by aphids, the tobacco leaves shrink and become thinner, and the severely damaged plants grow slowly, are prone to soot, and are brittle and lack luster after roasting. The cigarettes made are not good and have poor combustibility. And aphids can also spread a variety of viral diseases, such as cucumber mosaic virus (CMV), potato virus Y (PVY), tobacco vein mottle virus (TVMV), tobacco vein band mosaic virus (TvBMV), etc., to the production of tobacco. cause huge losses....
