     The LC50 of Hg to Chironomus Larva is higher than other insects, this may be related with the action mechanism of Hg, to generic insects, such as Dugesia japonica, they have comparatively complicated detoxifcation mechanism, the Hg can destroy the detoxifcation mechanism easily that makes the Dugesia japonica dead.
     汞对羽摇蚊幼虫的LC_(50)比其它昆虫要高,这可能与汞的作用机理有关,对于一般的昆虫,如三角涡虫都有比较复杂的解毒机制,汞很容易破坏其解毒机制而使其致死,而摇蚊幼虫没有复杂的解毒机制所以对汞的耐性稍高。
