[Effect of Different Land Use Types on the Diversity of Soil Bacterial Community in the Coastal Zone of Jialing River].

The purpose of this study was to clarify the differences in soil bacterial community diversity in different land uses in the coastal zone of the Jialing River and to provide theoretical reference for reasonable land development and resource protection of the Jialing River basin. Based on second generation high-throughput sequencing technology, the diversity, structural composition, functional types, and influencing factors of soil bacterial communities in different land use types were analyzed. The results showed that:① there were some differences in soil physical and chemical properties among different land uses.

[Deltamethrin resistance, metabolic detoxification enzyme and kdr mutation in Anopheles sinensis in region along Huaihe River in Anhui Province].

Objective: To understand the deltamethrin resistance level, GTS and P450 metabolic detoxification enzyme activities, and mutations in the para-type sodium channel gene that confers knockdown resistance (kdr) in Anopheles sinensis mosquitoes from malaria endemic areas along the Huaihe River in Anhui Province, China.

Methods: An. sinensis adult mosquitoes were collected in Lilou, Mohekou and Tuohu townships of Bengbu City, Anhui Province from August to September, 2011.
