A significant difference (p = 0.05) was revealed between the formulation (T1) and the control (T0) in the field on the seed germination rate of okra varieties Clemson spineless (V1) (83.3 vs 94.4%; 88.8 vs 100%; 77.7 vs 88.8%) and Hire (V2) (77.7 vs 94.4%; 88.8 vs 100%; 83.3 vs 88.8%) in agroecological areas V, III and IV respectively. The same effect observed on plant health with bioformulation was significant compared with the control in terms of protection against cercosporiosis pathogens. The protection ranges according to treatment and control for the two okra varieties in agroecological areas V, III and IV were 79.24 vs. 86.48%; 100 vs. 100%; 77.76 vs. 91.82% for variety V1 and 88.88 vs. 94.44%; 94.44 vs. 100%; 83.33 vs. 94.44% for variety V2. Gas chromatography combined with mass spectrometry revealed an overproduction of bioactive molecules in the hydro-methanolic extracts of okra leaves treated with the formulation, which are responsible for its bioprotection in the three agroecological areas. In conclusion, the use of the Trichoderma harzianum and Bacillus amyloliquefaciens formulation on okra crops significantly induced germination and systemic resistance of Abelmoschus esculentus plants against cercosporiosis agents.","PeriodicalId":15023,"journal":{"name":"Journal of Advances in Biology & Biotechnology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135199436","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}

The fieldwork was carried out in humid period on two study sites: 1– rubber landscape (secondary forest, 7-, 12- and 25-year-old rubber plantations) and 2– oil palm landscape (secondary forest, 13-, 20- and 39-year-old oil palm plantations). Three sampling stands were established in each land-use type and age class, for a total of 24 sampling stands. On each sampling stands, soil cores for Gamasid mite’s extraction were taken at 10 cm soil depth through a 40–50 m transect. Our findings highlighted a drop of mesostigmatid mites’ density (–49% and –52%), species richness (–41% and –40%), and diversity (–35% and –49%), respectively after conversion of the secondary forests into rubber and oil palm plantations. The soil with clayey sandy and clayey textures favored the development of the mesostigmatid mites, particularly in the abundance and species richness of Uropodina. However, the soil with sandy clayey textures improved the abundance and species richness of Gamasina. The mesostigmatid mites’ community was degraded in sandy-textured soils. In light of the Maturity Index values, a better quality of soil and environment was detected in the secondary forests compared to plantations. The results also suggest that the mesostigmatid mites’ community influence the soil nutrients and probably plant productivity indirectly by influencing the populations of their prey.","PeriodicalId":15023,"journal":{"name":"Journal of Advances in Biology & Biotechnology","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74901699","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}

Blood samples were collected in Jacqueville and Tiassalé. The different haematological parameters were identified by an automated haematological analyser. The coefficient of determination (R2) was determined to show the proportion of variation in parasite density and each haematological parameter. A total of 69 patients were sampled. A negative correlation was observed between parasite density and haemoglobin in the general population, in Jacqueville and in Tiassalé.
