The species' density of the gypsy moth will be controlled under economic permitted level.(終將舞毒蛾的種群密度控制在經濟允許水平之下。)

In stands dominated by trees such as aspen, however, incipient gypsy moth outbreaks are quickly suppressed by viral epidemics.(然而，在以白楊等樹為主的林分，最初的舞毒蛾爆發很快就被病毒流行病所抑制。)

The gypsy moth is also subject to attack by the nucleopolyhedrosis virus, or wilt disease, a particularly important killer of the caterpillars in outbreak years.(舞毒蛾還會受到核多角體病毒或萎蔫病的攻擊，在毛蟲爆發的年代，這是一種特別重要的殺手。)

Spiders also attack the much-feared gypsy moth.(蜘蛛也襲擊令人害怕的舞毒蛾。)
