A survey was conducted from May to Oct of 2011 of the parasitoid community of the imported cabbageworm, Pieris rapae (Lepidoptera: Pieridae), in cole crops in part of the eastern United States and southeastern Canada. The findings of our survey indicate that Cotesia rubecula (Hymenoptera: Braconidae) now occurs as far west as North Dakota and has become the dominant parasitoid of P. rapae in th...

Reinvestigation of the fermentation broth and mycelium of the fungus Phoma herbarum led to the isolation of a new phytotoxic nonenolide, namely, (7R,9R)-7-hydroxy-9-propyl-5-nonen-9-olide, which was designated with the trivial name herbarumin III (3). The known compounds herbarumins I (1) and II (2) were also obtained. The structure of 3 was elucidated by spectroscopic methods and molecular mod...

The wellbeing of marine organisms is connected to their microbiome. Oysters are a vital food source and provide ecological services, yet little known about how climate change such as ocean acidification warming will affect We exposed the Sydney rock oyster, Saccostrea glomerata, orthogonal combinations temperature (24, 28 °C) pCO2 (400 1000 ?atm) for eight weeks used amplicon sequencing 16S rRN...

The objective of the study was to evaluate the effect of the biostimulant Kelpak on true protein and simple sugar contents of Dactylis glomerata and Festulolium braunii at different nitrogen rates. A field experiment was set up as a randomised sub-block design (split-split-plot) with three replicates. The following factors were ha, pure-sown grass species and cultivars (monoculture). Protein co...

The presence of potentially toxic elements (PTEs) in soils can upset the natural balance and increase risk PTE incorporation into food chain. use composite biochar with municipal sewage sludge compost (MSSC/C) be an effective way both managing waste, such as sludge, providing additive-supporting phytostabilization processes. effectiveness D. glomerata MSSC/C technique assisted industrially cont...

Isothiocyanates and substituted pyrazoles were combined to form a series of novel isothiocyanates with highly effective herbicidal activity. The target compounds were analyzed by elemental analysis, 1H-NMR, EI-MS and IR spectroscopy. The synthesized compounds, particularly compounds 3-1 and 3-7, exhibited good herbicidal activities against four weeds. The EC(50) values of compound 3-1 against E...
