BACKGROUND Tree-killing bark beetles (Coleoptera, Scolytinae) are among the most economically and ecologically important forest pests in the northern hemisphere. Induction of terpenoid-based oleoresin has long been considered important in conifer defense against bark beetles, but it has been difficult to demonstrate a direct correlation between terpene levels and resistance to bark beetle colon...

--Sweetgum and water oak trees samp~ed from a plantation over 7 years were used to test whether primary tree component (bole wood, bole bark, limb wood, timb bark, and leaves) predictions could be summed to estima~e total bole. total limb. and total tree values. Estimattons by summing primary component predictions were not significantly different from predictions for the totals, but pr~diction ...

Lindgren funnel traps baited with aggregation pheromones are widely used to monitor and manage populations of economically important bark beetles (Coleoptera: Scolytidae). This study was designed to advance our understanding of how funnel trap catches assess bark beetle communities and relative abundance of individual species. In the second year (2005) of a 3-yr study of the bark beetle communi...

For economic, agricultural, and environmental reasons, composting is frequently used for organic waste recycling. One approach to limiting the potential risk from bacterial food-borne illnesses is to ensure that soil amendments and organic fertilizers are disinfected. However, more knowledge concerning the microbiological safety of composted substrates other than sludge and manure is necessary....

Research on biosorption of organic dyes is an important subject for the development clean technologies treatment textile wastewater. In this work, process sorption four different natures, namely Basic Violet 10 (BV10), Acid Red 27 (AR27), Direct Blue 151 (DB151) and Reactive 4 (RV4) onto two composts, pine bark compost municipal solid waste compost, has been studied. For this, kinetics equilibr...
