OFFICIAL EXPLANATION
E
When a modifying phrase is separated by two commas, the sentence should be grammatically correct without it. (A) is not: "The gypsy moth it has established itself". The "it" is problematic. That eliminates choices (A) and (B).
One key difference among the remaining choices is the verb containing the word "eradicated". (E) is only "eradicated", while (C) is "has been eradicated" and (D) is "having been eradicated". "Eradicated" is sufficient on its own, so (E) is the most likely correct choice. (C) is incorrect also because it connects the moth's eradication and its ability to defoliate in the same phrase - those are contradictory. (D) is incorrect also because of the redundancy of "Although" and "still". One or the other is fine, but both are not necessary. (E) is correct.
