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 a myzus persicae attractant and a preparation method thereof. The myzus persicae attractant is prepared by using liquid paraffin as a solvent and then mixing 0.1% to 1% by volume of an alpha-phellandrene solution, a cis-3-hexen-1-ol solution, a jasmonic acid methyl ester solution and an octanol solution in ratio. The attractant is a specific component selected from plant volatiles and has the characteristics of being high in selectivity and high in pertinence. The attractant can attract myzus persicae and is of important significance on reduction of damage of myzus persicae to tobacco and reduction of virus diseases of tobacco.

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 Myzus persicae (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 losse...
