Until now this disease has been difficult to control; while the bacteria attack the xylem vessel they cannot be reached by any bactericide. Biocontrol is potential for controlling this disease. One group of important biocontrol agents is the plant growth promoting rhizobacteria (PGPR). Based on in planta screening method, we have found 13 indigenous rhizobacterial strains from healthy chili’s rhizosphere, which have the ability to control bacterial wilt and to increase growth and yield of chili. This research is aimed at characterizing the direct mechanisms of selected indigenous rhizobacterial strains as biocontrol agents of R. solanacearum in vitro. The physiological characters of indigenous rhizobacterial strains as biocontrol agents had been observed, including production of antibiotic, siderophore, HCN, haemolysine, protease, and biosurfactan. For root colonization rifampicin mutants of indigenous rhizobacterial strains had been the results of in vitro analysis showed that those selected rhizobacterial strains had various physiological characters as biocontrol agents. Not all biocontrol tested characters have been produced by indigenous rhizobacterial strains. Only RZ2.1AP4 strains showed the positive on 3 characters. All indigenous rhizobacterial strains produced biosurfactant but only Pseudomonas hibiscicola strain RZ1.1AG4 showed the highest viscosity. All rifampicin mutants of indigenous rhizobacterial strains have colonized chili roots on rhizoplane and in the root tissues (endophyte) from nursery until 9 days after planting. RZ2.1AP2 and Klebsiela michiganensis strain RZ1.3AG4 showed the highest bacterial population on chilli roots. The bacterial population was higher in root tissue (endophytes) than on the root surface (rhizoplane) from seedling stage until 9 days after transplanting.","PeriodicalId":15069,"journal":{"name":"journal of biopesticides","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47257891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different alternative strategies have been pursued for the management of this pest to avoid the excessive use of chemical products of high toxicological levels. Within these strategies is included the use of ethanolic and oily extracts from plants belonging to various plant families exhibiting acaricidal activity. For this reason, the objective of this work was the selection and evaluation of some botanical extracts from native plants in Colombia that can be used to manage T. urticae. Thus, as part of our research on bioacaricides, the direct effect of five plant extracts on the mortality and fecundity of the egg, larva, nymph and adult stages of the mite and the chemical composition of each extract was additionally determined by high performance liquid chromatography coupled with mass spectrometry (LC/MS). It was found that the test extracts showed a low efficiency on eggs, larvae and nymphs of T. urticae, since mortalities did not reach 50%. However, in the case of adults, the extracts of Cnidoscolus aconitifoluis, Copaifera oficinalis and Anadenanthera peregrina could be suggested as promissory extracts for the management of adults of T. urticae, since they caused mortalities greater than 60% and reduced female fecundity. The main secondary metabolites identified were flavonoids, whose presence in test extracts would be associated with the acaricidal potentiality referred to.","PeriodicalId":15069,"journal":{"name":"journal of biopesticides","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48601990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the morning, interplant movement of foragers was significantly longer and they were moving at higher places of phacelia patches. They approached and probed flowers considerably longer in morning compared to afternoon. A significant positive relationship between the number of open flowers in a patch and the patch residence time was observed in the morning. The proportion of females having swollen abdomen filled with phacelia pollen (68.2%) in the afternoon was significantly higher than that (31.82%)in the morning. In our study, E. balteatus females spent more time foraging in phacelia patches in morning compared to afternoon.
