ABSTRACT
To clear the effect of the wound to the growth of the larva of the host to the Ophiocordyceps sinensis, the wounds of same severity at the same position were made artificially to the larva and which were artificial fed at the same environment and condition. The results indicated that, over the winter, the survival rate of the wounded of the infection larva was lower than that of the healthy larva, but the weight had no significant difference between the wounded and the healthy larva. The survival rate of the wounded of the no infection larva was lower than that of the healthy larva, but except with black skin, the wounded larva with offwhite and dusty red had no influence on the variety of the weight. In summery, wound had no advantage to the survival rate, but had no influence to the weight. The result had provided theoretical basis to the reforming of the system of the artificial culture O. sinensis.

OBJECTIVE: To study the biological character of Hepialus introduced from Yunnan province. METHOD: H. jianchuanensis introduced from Yunnan was bred artificially to observe its biological character. RESULT: The pupa duration was about 40 d, pupa emergence lasted for one day, female to male ratio was about 1.2:1, the mating peak was 19:30-20:30, the adults duration was about 25 d, the average life time of female was 5-6 d and that of male 6-7 d, the average number of the producing egg was about 300, the average weight of the 100 eggs was 10.33 mg. Lasting period of the larva is 350 d and the infancy larva showed the character of the polyphagy and cold endurance. CONCLUSION: Results indicate that there are some differences in the whole duration, weight of the 100 eggs and the number of the eggs left in the abdomen between H. jianchuanensis and others bred at the Kangding base.

UNLABELLED: To study the effects of the integrated pest control techniques on growth of host larvae of Cordyceps sinensis. METHOD: The integrated pest control techniques were compared with conventional techniques to evaluate the effects on growth of host larvae. RESULT AND CONCLUSION: The results showed that the techniques had broken the balance of the microbial living in the material, produced effective inhibition on the pests, raised the survival rate and promoted the growth of the host larvae at the same time.
