Changes in Transcriptome and Gene Expression in Sogatella furcifera (Hemiptera: Delphacidae) in Response to Cycloxaprid.

The white-backed planthopper, Sogatella furcifera (Horváth), causes substantial damage to crops by direct feeding or virus transmission, especially southern rice black-streaked dwarf virus, which poses a serious threat to rice production. Cycloxaprid, a novel cis-nitromethylene neonicotinoid insecticide, has high efficacy against rice planthoppers, including imidacloprid-resistant populations. However, information about the influence of cycloxaprid on S.

Expression Differences of Resistance-Related Genes Induced by Cycloxaprid Using qRT-PCR in the Female Adult of Sogatella furcifera (Hemiptera: Delphacidae).

As a newer cis-nitromethylene neonicotinoid pesticide at present, cycloxaprid has good industrialization prospects, including the management of imidacloprid-resistant populations, because this chemical have an excellent efficiency against rice planthoppers. Sogatella furcifera (Horváth) is the most economically important pest of rice worldwide and has developed resistance to many insecticides. This study focused on the expression change of these resistance genes, induced by cycloxaprid, involved in metabolic detoxification and receptor protein.

Monitoring Trends in Insecticide Resistance of Field Populations of Sogatella furcifera (Hemiptera: Delphacidae) in Guizhou Province, China, 2012-2015.

Sogatella furcifera (Horváth) is a migratory insect that is one of the most important pest species on rice in many Asian countries. Control of S. furcifera (Hemiptera: Delphacidae) primarily depends on the use of chemical insecticides, and with this extensive reliance on pesticides, determining the degree of resistance of S.

Green tea drinking habits and gastric cancer in southwest China.

Aim: The purpose of this study was to investigate relationships between green tea consumption and gastric cancer development.

Methods: A population-based case-control study including 200 cases and 200 controls was conducted in the southwest area of China from May 2010 to February 2011. A self-designed questionnaire was used to collect data on factors influencing gastric cancer development, including tea drinking, conditional logistic regression being used to calculate odds ratios (ORs) and corresponding 95% confidence intervals (95% CIs).

[A comprehensive prevention programs on AIDS, HBV and syphilis among pregnant women and couples experienced premarital medical examination].

Objective: To evaluate the effect of comprehensive prevention programs on HIV, HBV and syphilis transmission from mother to child and between premarital couples.

Methods: HIV, HBV and syphilis were screened among pregnant women with interventional measure for infected women; HIV, HBV and syphilis (TP) were screened among premarital couples with medical advice.

Results: The HIV, HBsAg and TP positive rates were 8.
