Effects of Aphidius gifuensis Release on Insect Communities and Diversity in Tobacco Fields of Yunnan Province, China.

Background And Objectives: The biocontrol agent Aphidius gifuensis has widely been released and applied since 1997 to control Myzus persicae in tobacco fields of Yunnan Province, southwestern China, but its ecological effects on the local insect community and diversity have not been described. Biological control agents may effect a diversity of organisms as well as the target for control but such trophic cascades have seldom been studied. This study aimed to explore the effects of A.

Tobacco Rotated with Rapeseed for Soil-Borne Phytophthora Pathogen Biocontrol: Mediated by Rapeseed Root Exudates.

Black shank, caused by Phytophthora parasitica var. nicotianae, is a widespread and destructive disease of tobacco. Crop rotation is essential in controlling black shank.

[Impact of biocontrol agent Bacillus subtilis on bacterial communities in tobacco rhizospheric soil].

The impact of inoculation with the biocontrol agent Bacillus subtilis on bacterial communities and bacterial diversity in rhizospheric soil of Nicotiana tabacum was assessed by constructing a 16S rRNA gene clone library and conducting amplified ribosomal DNA restriction analysis (ARDRA). The bacterial diversity was evaluated by coverage value (C), Shannon index (H), Pielou evenness index (E) and Margalef richness index (R). Phylogenetic analysis revealed that the inoculation significantly affected the composition of bacterial communities in tobacco rhizospheric soil.
