INTRODUCTION The use of entomopathogenic fungi to control disease vectors has become relevant because traditional chemical control methods have caused damage to the environment and led to the development of resistance among vectors. Thus, this study assessed the pathogenicity of entomopathogenic fungi in Triatoma dimidiata. METHODS Preparations of 108 conidia/ml of Gliocladium virens, Talarom...

A phytochemical investigation of Ficus virens leaves led to isolation of six flavonoids (1–6). On the basis of 2D and/or 1D NMR, and mass data, together with the comparison with the literature values, the flavonoids were identified as quercetin (1), quercetin-3-O-α-D-arabinopyranoside (2), quercetin-3-O-β-Dgalactopyranoside (3), kaempferol-3-O-α-D-arabinopyranoside (4), kaempferol-3-O-β-Dgalact...

In recent years, extreme weather has become more and frequent. The heat in summer is a serious threat to human health. Chongqing one of the hottest cities China, high temperature can cause skin cancer stroke. Green plants residential areas play great role cooling down air temperature. However, there are no accurate numerical references for which have better effect. Therefore, seven species tree...

Several Trichoderma virens (syn. Gliocladium virens) strains have good biocontrol activity against Rhizoctonia solani on cotton but lack some of the commercially desirable characteristics found in other Trichoderma species. In an attempt to combine these desirable characteristics, we used a highly effective biocontrol strain of T. virens in protoplast fusions with a strain of T. koningii, which...

Rice false smut (RFS) is an important rice disease that is caused by the pathogen Ustilaginoidea virens. In this study, we developed a real-time polymerase chain reaction (PCR) assay to detect U. virens and to estimate the level of disease. The genomic DNAs of U. virens and rice were extracted together from the rice samples. Real-time PCR assays were performed and compared to conventional neste...

Gliocladium virens is a common saprophytic fungus that is mycoparasitic on a large number of fungi. Responses of G. virens toward its environment were examined by monitoring the presence of extracellular proteins in culture fluid during time course experiments. Culture fluid of G. virens grown on glucose, washed cell walls of Rhizoctonia solani (one of its hosts), olive oil, or chitin contained...

We have previously shown that the beneficial filamentous fungus Trichoderma virens secretes the highly effective hydrophobin-like elicitor Sm1 that induces systemic disease resistance in the dicot cotton (Gossypium hirsutum). In this study we tested whether colonization of roots by T. virens can induce systemic protection against a foliar pathogen in the monocot maize (Zea mays), and we further...

Ficus is a exible replication facility with optimistic concurrency control designed to span a wide range of scales and network environments. Support for partitioned operation is fundamental to the Ficus design but was not widely exercised in early Ficus use. This position paper reports recent experiences using Ficus in settings where some replicas are only occasionally connected to a network, a...
