The lecturer claims that three methods to solve a problem of emerald ash borer is incapable.
This contradicts the reading's passage that there are several ways to solve the problem of wood of ash trees destroyed by emerald ash borer.

The lecturer, however, challenges this particular viewpoint by arguing that the trees of a symptom which are used by living place for the borers occur at least after two years.
To be more specific, it is hard to find the infested tree due to an innumerous number of trees except an urbane area.
Another point puts the article an emphasis on is that insecticidescan cease the adult borers from laying their eggs and wipes out larvaes.
In contrast, the lecturer contends that the insecticides contaminate a water under the ground and it is useless in some circumstance.
He further indicates that If a lot of larvae already live in the tree, the insecticides can't make a good result since the larvae block the circulatory system to draw up the insecticide.
Finally, it is stated in the reading that wasps annihilate borer larvae by laying their eggs in them.
On the contrary, it is accentuated in the lecture, wasp's surviving is eagerly depending on the region, it is different with borer.
He gives a detail that using wasps can harm other organisms in the tree.
