The efficiency of a series of wetland colonized with Eichhornia crassipes and Salvinia molesta to treat the effluent of a giant river prawn (Macrobrachium rosenbergii) broodstock pond was evaluated in this study. The experimental design was completely randomized and was performed in 9 rectangular tanks (1.6 m3) with three treatments (constructed wetlands) and three replicates. The treatment typ...

Males of two species of moths (Grapholitha molesta (Busck) and Hehothis virescens (F )) were flown in a sustained-flight tunnel in horizontal pheromone plumes The up-tunnel velocity of the moths increased with increasing height of flight and for G molesta was independent of tunnel wind velocities Use of moving ground patterns verified that the height of flight above the ground was the factor re...

Salvinia molesta Mitchell, a floating invasive aquatic plant, is one of the top 10 worst invasive aquatic weeds in the world. It was discovered in the lower Pascagoula River in 2005 and evidence suggests that this non-native species is spreading along the northern Gulf of Mexico. These plants exhibit rapid growth and nutrient uptake rates, allowing them to out compete other plants in similar ha...

Tingginya kadar fosfat, BOD, dan COD disebabkan oleh pembuangan limbah dari kegiatan laundry ke dalam badan air tanpa pengolahan yang memadai. Penelitian ini bertujuan untuk mengurangi dengan menggunakan berbagai jenis tanaman. Tanaman digunakan penelitian meliputi Pistia stratiotes, Salvinia molesta, serta kombinasi kedua tanaman tersebut. Metode eksperimen adalah sistem batch. Hasil menunjukk...

Salvinia molesta D. S. Mitchell (Salviniaceae) is an invasive aquatic plant that causes environmental and economic damage, but its rapid growth in eutrophic media can be used for the biotechnological use of biomass. Thus, aim this work was to determine best technique lipid extraction from molesta, testing solvents hexane:methanol (2:1 v/v), ethanol:water (10% v/v) (4 % association with auxiliar...

The soft coral genus Sinularia is a rich source of bioactive metabolites containing a diverse array of chemical structures. A solvent extract of Sinularia polydactyla resulted in the isolation of three new casbane diterpenes: sinularcasbane M (1), sinularcasbane N (2) and sinularcasbane O (3); in addition, known metabolites (4-5) were isolated. Compounds were elucidated on the basis of spectros...
