ABSTRACT Entomopathogenic fungi can regulate insect populations and function as crucial biological control agents against insect pests, but their impacts on nontarget microorganisms are poorly understood. In this study, we investigated the potential of the fungal strain Metarhizium anisopliae CQMa421 to control rice planthoppers under field conditions and its effects on rice microbiota. This fungus suppressed rice planthoppers during this period, and its control efficiency was more than 60% 7 days after application and did not significantly differ from that of the chemical treatment except in 2019. Both treatments showed a smaller population of rice planthoppers than the controls. After application, M. anisopliae was maintained on rice plants for approximately 14 days, showing a decreasing trend over time. Furthermore, the results showed that the bacterial and fungal richness (operational taxonomic units) and diversity (Shannon index) did not significantly differ between the fungal treatment and the controls after application. The major bacterial taxa of Proteobacteria (including Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, and Deltaproteobacteria), Actinobacteria, Bacteroidetes, and Cyanobacteria accounted for more than 80% of the bacterial community after fungal application, and the major fungal taxa Ascomycota (including Eurotiomycetes, Dothideomycetes, and Sordariomycetes) and Basidiomycota (including Ustilaginomycetes) represented more than 90% of the fungal community. However, the microbial communities of the rice phyllosphere did not significantly change after entomopathogenic-agent application, indicating that the indigenous microbial communities may adapt to fungal insecticide application. Taken together, the results suggest that this fungal agent has good potential for rice planthopper control with no substantial effects on rice microbial communities. IMPORTANCE Entomopathogenic fungi may be used as crucial biocontrol agents for the control of insect pests, but few effective fungal strains have been reported for the control of the rice planthopper, a major pest of rice. More importantly, the impacts of fungal insecticide application on nontarget microorganisms have not been well evaluated, especially under field conditions. Therefore, in this study, we investigated the effects of the fungal strain M. anisopliae CQMa421 on rice planthopper populations from 2017 to 2019 and evaluated its potential impacts on the microbiota of rice plants after application. The results suggested that this fungal agent has good potential for use in the control of rice planthoppers with no significant effects on rice microbial communities, representing an alternative strategy for the control of rice pests.

In order to develop new antimicrobial agents, a series of 3-formyl indole based Schiff bases were synthesized by reacting 3-formyl indole(indole-3-carboxaldehyde) with substituted aniline taking ethanol as solvent. The reaction was carried in the presence of small amount of p-toluene sulphonic acid as catalyst.All the synthesized compounds were characterized by IR, 1H-NMR spectral analysis. All the synthesized compounds were evaluated for antimicrobial activity against two gram positive bacterial strains (B. subtilisand S. aureus) and two gram negative bacterial strains (P. aeruginosaand E. coli) and one fungal strain (C. albicans). All the synthesized compounds were found to have moderate to good antimicrobial activity. The  standard drug amoxicillin, fluconazole were used for antimicrobial activity. Among the synthesized compounds, the maximum antimicrobial activity was shown by compounds GS04, GS07, GS08 and GS10.

En busca de una alternativa de control del mosquito Culex quinquefasciatus en áreas urbanas se desarrolló el proyecto: “Evaluación de microorganismos biocontroladores sobre el mosquito Culex quinquefasciatus” cuyo objetivo fue evaluar la capacidad biocontroladora de diferentes hongos entomopatógenos sobre larvas del mosquito a nivel de laboratorio. Se evaluaron 16 aislamientos de hongos en diferentes concentraciones. Se constataron diferencias en el porcentaje de mortalidad producido en larvas de Cx. quinquefasciatus dependientes del tipo de aislamiento, de la concentración utilizada y del tiempo de exposición. Los aislamientos que presentaron el nivel de mortalidad más alto pertenecen a la especie Metarhizium anisopliae, seguidos por aislamientos de la especie Beauveria bassiana. El aislamiento que presentó el mayor nivel de mortalidad (100%) en menor tiempo de exposición (24 horas) fue Metarhizium anisopliae 99068 en una concentración de 1x106 e/ml. Por lo tanto este aislamiento es recomendado para su evaluación en campo y desarrollo de un producto comercial.

Con el objetivo de evaluar cuatro cepas del hongo Metarhizium anisopliae (Metschincoff) Sorokin para el control garrapatas del genero Boophilus spp., se seleccionaron dos cepas de garrapatas para su evaluación en su fase adulta sobre terneros parasitados. Se utilizó un diseño completamente al azar, con seis tratamientos y diez repeticiones.En esta fase las cepas PLH y CH 93-3 fueron las que mostraron la mayor efectividad, por lo que fueron evaluadas en garrapatas adultas sobre terneros previamente parasitados; en la prueba in vivo se utilizó un diseño de bloques completamente al azar, cuatro tratamientos (Las dos cepas seleccionadas, un compuesto químico y un placebo a base de agua) y ocho repeticiones. Los resultados mostraron que las dos cepas evaluadas presentaron una efectividad del 50% con respecto al producto químico.
