In recent years, there is more and more debate about adherence and improve the system of tobacco monopoly or abolish tobacco monopoly system. With the increasing competition in the international tobacco market, it makes China’s tobacco industry have received the unprecedented challenge. In the face of economic globalization, with the modern advanced information technology to build the tobacco industry logistics, which is the way for the survival and development in the future for China’s tobacco industry. And the cost of distribution in tobacco companies occupy large proportion of the total cost of logistics, so we optimize the tobacco company logistics distribution costs based on the information environment. At last, we put forward the model of optimization of fuel management of distribution *** purpose is to reduce logistics distribution costs of tobacco companies, and improve the market competitiveness.

Changes in gene expression are associated with the evolution of pesticide resis-tance in *** this study,transcriptome sequencing was performed in 3 different resistance levels(low,L;medium,M;and high,H)of cyflumetofen-resistant strain(YN-CyR).A total of 1685 genes,including 97 detoxification enzyme genes,were upregulated in all 3 stages,of which 192 genes,including 11 detoxification enzyme genes,showed a continuous increase in expression level with resistance development(L to H).RNA in-terference experiments showed that overexpression of 7 genes(CYP392A1,TcGSTd05,CCE06,CYP389A1,TcGSTz01,CCE59,and CYP389C2)is involved in the development of cyflumetofen resistance in Tetranychus *** recombinant CYP392A1 can effectively metabolize cyflumetofen,while CCE06 can bind and sequester cyflumetofen in *** compared 2 methods for rapid screening of resistance molecular markers,in-cluding short-term induction and 1-time high-dose *** detoxification enzyme genes were upregulated in the field susceptible strain(YN-S)by induction with 20%lethal concentration(LC2o)of ***,16 detoxification enzyme genes were up-regulated by 1-time selection with LCso of ***,the 16 genes were overexpressed in all 3 resistance *** results indicated that 1685 genes that were upregulated at the L stage constituted the basis of cyflumetofen resistance,of which 192 genes in which upregulation continued to increase were the main driving force for the de-velopment of ***,the 1-time high-dose selection is an efficient way to rapidly obtain the resistance-related genes that can aid in the development of resistance markers and resistance management in mites.
