The morphology and ultrastructure of the metathoracic scent glands (MTG) of Eurygaster maura were studied by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Also, extracts of the volatile fraction of the MTG secretion from males and females were analyzed by capillary gas chromatography-mass spectrometry (GC-MS). In SEM investigations, MTG are composed of a reservo...

This plant is medicinally much famous. The biological activities of this plant were carried out by using standard procedures. The aim of this work was to investigate the in vitro antimicrobial...

The brown marmorated stink bug, Halyomorpha halys Stål (Hemiptera: Pentatomidae), is an invasive pest in America, Europe and Asia causes serious economic loss to crops, nuisance problems during overwintering. Uninvaded southern hemisphere countries, such as New Zealand Australia, see increase H. border interceptions the northern populations’ overwintering period large aggregations of can settle...

This work was aimed at isolating and characterising biosurfactant producing bacteria strain from diesel oil contamination sites. The potential of the to degrade n-alkanes further studied. Soil samples were collected rich areas, identified strains grown on minimal media that contained as only carbon source. Enrichment culture technique used identify bacteria. Seventeen based their capacity use O...

Biodegradation of crude oil and 7 different distillation products by Ralstonia picketti SRS and Alcaligenes piechaudii SrS was investigated. Crude oil degradation was above 80% after incubation of 20 days for both strains and their mixture. removal of short/long alkanes and BteX investigated was different, from 97% (for hexane degraded by the mixture of the isolates) to 22% (for tridecane degra...

The title compound, C(13)H(20)O(4)Si(2), is a siloxane-functionalized norbornane anhydride. Both five-membered heterocyclic rings of the mol-ecule have a planar structure, whereas the two five-membered aliphatic rings assume envelope conformations. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.
