Juncus tenuis Willd. is a warm-season, perennial weed of turfgrass. In wet and compacted soils, it well documented, yet little known regarding the interaction effects compaction soil moisture on its rooting foliar growth. A greenhouse experiment examined above- belowground growth J. tenuis. The experimental design was completely randomized with 3 × arrangement four replications two runs. Factor...

Aspergillus niger van Tieghem, Aspergillus tamarii Kita, and Aspergillus flavus Link ex Fries utilized the methylthio moiety of 2,4-bis(isopropylamino) -6-methyl-mercapto-s-triazine (prometryne) as a sulfur nutrient source. Other soil fungal isolates not affected by prometryne concentrations to 1 mg/ml culture included: Aspergillus oryzae (Ahlburg) Cohn, Curvularia lunata (Wakker) Boedijn, Tric...

Seven microsatellite loci were isolated and characterized from a microsatellite enriched genomic library for the stingless bee Scaura latitarsis. Primers were tested in 12 individuals. The number of alleles per locus ranged from 3 to 6 (mean = 4.29) and observed heterozygosity ranged from 0.00 to 0.75 (mean = 0.40). Cross-species tests showed successful amplification for Scaura atlantica, Scaur...

Biweekly field visits starting from January to the end of April 2011 were conducted to tomato fields (open and plastic houses) heavily infested with the tomato borer Tuta absoluta, in order to survey natural enemies associated with this pest. Three hemipterans were found: Orius albidipennis, Orius sp. (Anthocoridae) and Nesidiocoris tenuis (Miridae). In addition, the parasitic wasp Bracon (Habr...
