Abstract:

A lot of prepupae of Artona funeralis were collected in succession after they broke out in a large area and were reared in the lab.during the process,11 species of parasitic enemies,1 white muscardine fungi,3 parasitic flies and 7 parasitic chalcids were discovered.All the parasitic flies and chalcids collected are new record enemies of A.funeralis in China.Two newly-recorded genus,Diaglyptidae Vieredc and Caenocryptoides Vchida and 1 newly-recorded species,Theronia depressa were discovered.There were 4 dominant species among the 11 parasitic natural enemies,and the parasitic rate of each enemy is over 10%.Extraordinarily,the parasitic rate of C.sp.is 47%.C.sp.could complete 3 generations during the period of prepupa for overwintering of A.funeralis in bamboo forest.

Key words: Artona funeralis, parasitic fungi, parasitic chalcid, newly-recorded host, Chinese newly-recorded species, Chinese newly-recorded genus
