The outdoor parasitical efficiency of T. brontispae was normally 40%-50% and tiptop was 100%, A. hispinarum was normally 20%-30% and tiptop was 47%.
In this paper, embryonic development, parasitizing behavior of the parasitical insect and population rejuvenation after successive rearing with the pupa of Tenebrio molitor were studied.
Compared with Japanese eel, European eel has a poorer appetite for food and is susceptible to both bacterial and parasitical diseases.
