> <b>Theory behind Trap Trees</b><P>
> <P>
> An elm tree which is unwanted or which has been diagnosed to have
> Dutch Elm Disease is killed using herbicides applied to wounds
> made in the trunk. This renders the elm attractive to the
> European and Native elm bark beetles (<I>Scolytus
> multistriatus</I> and <I>Hylurgopinus rufipes</I>, respectively).
> The bark beetles subsequently attack and colonize the dead/dying
> tree and set up brood colonies. However, the herbicides result in
> drying of the bark causing brood to fail. Therefore, each year
> that trap trees are used, a compounded decrease in bark beetle
> populations results.<P>
> <P>
> For example, a study conducted in New York by professor Gerald
> Lanier found that each beetle which infests an elm tree normally
> produces 8.5 new beetles. However, if an elm which is less than
> 50% wilted is killed by herbicides, each beetle infesting the
> tree will produce only 2% of its potential brood. This
> illustrates the important point that early detection of Dutch elm
> disease is integral to the success of the trap tree method. Only
> 52% of potential brood was eliminated if an elm was treated with
> herbicide after it was already 90% dead from
> Dutch elm</title><FONT SIZE="2" COLOR="#E005CA">CheatingHousewivesLookingForSexxInYourNeighborhood
